非表示の管理機能を有効にしてすべてのサイト設定を表示

テスト対象: WordPress 3.1 RC3

この小さなコードは、かなりクールなことをします.「すべての設定」へのリンクを含むオプションが設定メニューに追加されます.これにより、WordPressサイトに関連するデータベース内のすべての設定の完全なリストが表示されます.以下のコードは、このリンクを管理者ユーザーにのみ表示し、他のすべてのユーザーには非表示にします.

 // CUSTOM ADMIN MENU LINK FOR ALL SETTINGS
   function all_settings_link() {
    add_options_page(__('All Settings'), __('All Settings'), 'administrator', 'options.php');
   }
   add_action('admin_menu', 'all_settings_link');
 

Enable Hidden Administration Feature displaying All Site Settings

Tested on: WordPress 3.1 RC3

This little piece of code does something pretty cool. It will add an additional option to your settings menu with a link to "all settings" which will show you a complete list of all the settings you have within your database related to your WordPress site. The code below will only made this link visible to an administrator user and hide it for all other users.

// CUSTOM ADMIN MENU LINK FOR ALL SETTINGS
   function all_settings_link() {
    add_options_page(__('All Settings'), __('All Settings'), 'administrator', 'options.php');
   }
   add_action('admin_menu', 'all_settings_link');

ログインロゴを変更＆amp;画像のURLリンク

テスト対象: WordPress 3.0.1

このコードを使用すると、WordPressログインページのロゴ、およびこのロゴのhrefリンクとタイトルテキストを簡単に変更できます.

 add_filter( 'login_headerurl', 'namespace_login_headerurl' );
/**
 * Replaces the login header logo URL
 *
 * @param $url
 */
function namespace_login_headerurl( $url ) {
    $url = home_url( '/' );
    return $url;
}

add_filter( 'login_headertitle', 'namespace_login_headertitle' );
/**
 * Replaces the login header logo title
 *
 * @param $title
 */
function namespace_login_headertitle( $title ) {
    $title = get_bloginfo( 'name' );
    return $title;
}

add_action( 'login_head', 'namespace_login_style' );
/**
 * Replaces the login header logo
 */
function namespace_login_style() {
    echo '<style>.login h1 a { background-image: url( ' . get_template_directory_uri() . '/images/logo.png ) !important; }</style>';
}
 

編集:サイトのロゴを使用してログインのロゴを置き換える場合は、以下を使用してその情報を動的に取得できます( WP3.5 でテスト済み) :

 function namespace_login_style() {
    if( function_exists('get_custom_header') ){
        $width = get_custom_header()->width;
        $height = get_custom_header()->height;
    } else {
        $width = HEADER_IMAGE_WIDTH;
        $height = HEADER_IMAGE_HEIGHT;
    }
    echo '<style>'.PHP_EOL;
    echo '.login h1 a {'.PHP_EOL; 
    echo '  background-image: url( '; header_image(); echo ' ) !important; '.PHP_EOL;
    echo '  width: '.$width.'px !important;'.PHP_EOL;
    echo '  height: '.$height.'px !important;'.PHP_EOL;
    echo '  background-size: '.$width.'px '.$height.'px !important;'.PHP_EOL;
    echo '}'.PHP_EOL;
    echo '</style>'.PHP_EOL;
}
 

Modify the Login Logo & Image URL Link

Tested on: WordPress 3.0.1

This code will allow you to easily modify the WordPress Login page Logo as well as the href link and title text of this logo.

add_filter( 'login_headerurl', 'namespace_login_headerurl' );
/**
 * Replaces the login header logo URL
 *
 * @param $url
 */
function namespace_login_headerurl( $url ) {
    $url = home_url( '/' );
    return $url;
}

add_filter( 'login_headertitle', 'namespace_login_headertitle' );
/**
 * Replaces the login header logo title
 *
 * @param $title
 */
function namespace_login_headertitle( $title ) {
    $title = get_bloginfo( 'name' );
    return $title;
}

add_action( 'login_head', 'namespace_login_style' );
/**
 * Replaces the login header logo
 */
function namespace_login_style() {
    echo '<style>.login h1 a { background-image: url( ' . get_template_directory_uri() . '/images/logo.png ) !important; }</style>';
}

EDIT: If you want to use the site logo to replace the login logo, you can use the following to dynamically pull that information (tested on WP3.5):

function namespace_login_style() {
    if( function_exists('get_custom_header') ){
        $width = get_custom_header()->width;
        $height = get_custom_header()->height;
    } else {
        $width = HEADER_IMAGE_WIDTH;
        $height = HEADER_IMAGE_HEIGHT;
    }
    echo '<style>'.PHP_EOL;
    echo '.login h1 a {'.PHP_EOL; 
    echo '  background-image: url( '; header_image(); echo ' ) !important; '.PHP_EOL;
    echo '  width: '.$width.'px !important;'.PHP_EOL;
    echo '  height: '.$height.'px !important;'.PHP_EOL;
    echo '  background-size: '.$width.'px '.$height.'px !important;'.PHP_EOL;
    echo '}'.PHP_EOL;
    echo '</style>'.PHP_EOL;
}

 return $query;
}
add_filter( 'the_search_query', 'searchAll' );

Add your custom post types to your sites main RSS feed by default.

// ADD CUSTOM POST TYPES TO THE DEFAULT RSS FEED
function custom_feed_request( $vars ) {
 if (isset($vars['feed']) && !isset($vars['post_type']))
  $vars['post_type'] = array( 'post', 'site', 'plugin', 'theme', 'person' );
 return $vars;

ADMINユーザーを除くすべてのユーザーの更新通知を削除する

テスト対象: WordPress 3.0.1

このコードは、＆quot; admin＆quot;以外のユーザーがいないことを保証します.アップデートが利用可能になると、WordPressから通知されます.

 // REMOVE THE WORDPRESS UPDATE NOTIFICATION FOR ALL USERS EXCEPT SYSADMIN
   global $user_login;
   get_currentuserinfo();
   if ($user_login !== "admin") { // Change admin to the username that gets the updates
    add_action( 'init', create_function( '$a', "remove_action( 'init', 'wp_version_check' );" ), 2 );
    add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );
   }
 

バージョンを変更して、(ユーザー 'admin'だけではなく)管理者ユーザーの更新通知のみを表示するようにしました:

 // REMOVE THE WORDPRESS UPDATE NOTIFICATION FOR ALL USERS EXCEPT SYSADMIN
       global $user_login;
       get_currentuserinfo();
       if (!current_user_can('update_plugins')) { // Checks to see if current user can update plugins
        add_action( 'init', create_function( '$a', "remove_action( 'init', 'wp_version_check' );" ), 2 );
        add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );
       }
 

Remove Update Notification for all users except ADMIN User

Tested on: WordPress 3.0.1

This code will ensures that no users other than "admin" are notified by WordPress when updates are available..

// REMOVE THE WORDPRESS UPDATE NOTIFICATION FOR ALL USERS EXCEPT SYSADMIN
   global $user_login;
   get_currentuserinfo();
   if ($user_login !== "admin") { // Change admin to the username that gets the updates
    add_action( 'init', create_function( '$a', "remove_action( 'init', 'wp_version_check' );" ), 2 );
    add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );
   }

Changed version to only show update notification for admin users (as opposed to just the user 'admin'):

// REMOVE THE WORDPRESS UPDATE NOTIFICATION FOR ALL USERS EXCEPT SYSADMIN
       global $user_login;
       get_currentuserinfo();
       if (!current_user_can('update_plugins')) { // Checks to see if current user can update plugins
        add_action( 'init', create_function( '$a', "remove_action( 'init', 'wp_version_check' );" ), 2 );
        add_filter( 'pre_option_update_core', create_function( '$a', "return null;" ) );

    }
}
 

RSSフィードへの公開投稿を遅らせる

テスト対象: WordPress 3.0.1

最後に、RSSフィードへの投稿を10〜15分間遅らせるのが好きです.これは、テキストに少なくとも2つのエラーが常にあるためです.その他の用途としては、コンテンツをRSSリーダーにプッシュする前に1日または1週間サイト専用にしたい場合があります.

 // Delay feed update
function publish_later_on_feed($where) {
    global $wpdb;

    if (is_feed()) {
        // Timestamp in WordPress format
        $now = gmdate('Y-m-d H:i:s');

        // Value for wait; + device

Add Spam & Delete Links to Comments on Front End

Tested on: WordPress 3.0.1

This makes it way easier to manage comments from the front end by adding spam and delete links.**

// Spam & delete links for all versions of WordPress
function delete_comment_link($id) {
    if (current_user_can('edit_post')) {
        echo '| <a href="'.get_bloginfo('wpurl').'/wp-admin/comment.php?action=cdc&c='.$id.'">del</a> ';
        echo '| <a href="'.get_bloginfo('wpurl').'/wp-admin/comment.php?action=cdc&dt=spam&c='.$id.'">spam</a>';
    }
}

Delay the public posting to RSS Feed

Tested on: WordPress 3.0.1

Finally, I like to delay posting to my RSS feeds for 10-15 minutes because I always find at least a couple errors in my text. Other uses are in case you want content to be exclusive to your site for a day or a week before pushing it out to your RSS readers.

// Delay feed update
function publish_later_on_feed($where) {
    global $wpdb;

    if (is_feed()) {
        // Timestamp in WordPress format
        $now = gmdate('Y-m-d H:i:s');

        // Value for wait; + device
        $wait = '10'; // integer

DBの肥大化を回避するために、ポストリビジョンの最大数を設定します.

テスト対象: WordPress 3.0.1

デフォルトは無限であり、これにより、最後の5つの編集のみを記憶するように設定されます:

 /**
 * Set the post revisions unless the constant was set in wp-config.php
 */
if (!defined('WP_POST_REVISIONS')) define('WP_POST_REVISIONS', 5);
 

その価値については、Codexページで設定できるCONSTANTSの優れたアイデアがたくさんあります wp-config.phpの編集.

Set a maximum number of post revisions to avoid DB bloat.

Tested on: WordPress 3.0.1

The default is infinite, and this will set it to only remember the last five edits:

/**
 * Set the post revisions unless the constant was set in wp-config.php
 */
if (!defined('WP_POST_REVISIONS')) define('WP_POST_REVISIONS', 5);

For what it's worth, there are a ton of great ideas for CONSTANTS that can be set on the Codex page Editing wp-config.php.

サイズ変更された画像をシャープにする(JPEGのみ)

この関数は、サイズ変更されたJPEG画像をシャープにします.違いの例:

「Wordpress」のすべてのインスタンスを自動的に変換するフィルターがWordPressバージョン3.0で追加されました.(大文字のPなし)から「WordPress」へ(大文字のPを使用)投稿コンテンツ、投稿タイトル、コメントテキスト.これを煩わしいと思う人もいますが、私は時々WordPressのケースを間違える必要があり、フィルターがやや煩わしいと感じました.

 // Remove annoying P filter
if(function_exists('capital_P_dangit')) {
    foreach ( array( 'the_content', 'the_title' ) as $filter )
        remove_filter( $filter, 'capital_P_dangit', 11 );

    remove_filter('comment_text', 'capital_P_dangit', 31 );
}
 

Remove "Wordpress" to "WordPress" filter

Tested on: WordPress 3.0.1

There was a filter added with WordPress version 3.0 that automatically converts all instances of "Wordpress" (no capital P) to "WordPress" (with a capital P) in post content, post titles, and comment text. Some people see this as intrusive, but I just have a need to mis-case WordPress from time to time and found the filter somewhat annoying.

// Remove annoying P filter
if(function_exists('capital_P_dangit')) {
    foreach ( array( 'the_content', 'the_title' ) as $filter )
        remove_filter( $filter, 'capital_P_dangit', 11 );

    remove_filter('comment_text', 'capital_P_dangit', 31 );
}

ダッシュボードをカスタマイズする

 add_action('wp_dashboard_setup', 'my_custom_dashboard_widgets');

function my_custom_dashboard_widgets() {
   global $wp_meta_boxes;
 

これらのダッシュボードウィジェットを削除します...

    unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_plugins']);
   unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_primary']);
   unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_secondary']);
 

「ヘルプとサポート」というカスタムウィジェットを追加します

    wp_add_dashboard_widget('custom_help_widget', 'Help and Support', 'custom_dashboard_help');
}
 

これはカスタムウィジェットのコンテンツです

  function custom_dashboard_help() {
    echo '<p>Lorum ipsum delor sit amet et nunc</p>';
}
 

Customize the Dashboard

add_action('wp_dashboard_setup', 'my_custom_dashboard_widgets');

function my_custom_dashboard_widgets() {
   global $wp_meta_boxes;

Remove these dashboard widgets...

   unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_plugins']);
   unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_primary']);
   unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_secondary']);

Add a custom widget called 'Help and Support'

   wp_add_dashboard_widget('custom_help_widget', 'Help and Support', 'custom_dashboard_help');
}

This is the content for your custom widget

 function custom_dashboard_help() {
    echo '<p>Lorum ipsum delor sit amet et nunc</p>';
}

カスタムユーザープロファイルフィールドの追加

以下のコードをfunctions.phpファイルに配置して、カスタムユーザープロファイルフィールドを追加します.必要に応じて行を編集または追加します.

次の行を削除しないことを忘れないでください:return $ contactmethods;そうしないと、これは機能しません.

 // CUSTOM USER PROFILE FIELDS
   function my_custom_userfields( $contactmethods ) {

    // ADD CONTACT CUSTOM FIELDS
    $contactmethods['contact_phone_office']     = 'Office Phone';
    $contactmethods['contact_phone_mobile']     = 'Mobile Phone';
    $contactmethods['contact_office_fax']       = 'Office Fax';

    // ADD ADDRESS CUSTOM FIELDS
    $contactmethods['address_line_1']       = 'Address Line 1';
    $contactmethods['address_line_2']       = 'Address Line 2 (optional)';
    $contactmethods['address_city']         = 'City';
    $contactmethods['address_state']        = 'State';
    $contactmethods['address_zipcode']      = 'Zipcode';
    return $contactmethods;
   }
   add_filter('user_contactmethods','my_custom_userfields',10,1);
 

カスタムフィールドを表示するには、以下の2つの方法のいずれかを使用できます.

オプション1:

 the_author_meta('facebook', $current_author->ID)
 

オプション2:

 <?php $current_author = get_userdata(get_query_var('author')); ?>
<p><a href="<?php echo esc_url($current_author->contact_phone_office);?>" title="office_phone"> Office Phone</a></p>
 

Add Custom User Profile Fields

Place the code below into your functions.php file to add custom user profile fields. Edit or add lines as you see fit.

Remember not to remove the line: return $contactmethods; otherwise this won't work.

// CUSTOM USER PROFILE FIELDS
   function my_custom_userfields( $contactmethods ) {

    // ADD CONTACT CUSTOM FIELDS
    $contactmethods['contact_phone_office']     = 'Office Phone';
    $contactmethods['contact_phone_mobile']     = 'Mobile Phone';
    $contactmethods['contact_office_fax']       = 'Office Fax';

    // ADD ADDRESS CUSTOM FIELDS
    $contactmethods['address_line_1']       = 'Address Line 1';
    $contactmethods['address_line_2']       = 'Address Line 2 (optional)';
    $contactmethods['address_city']         = 'City';
    $contactmethods['address_state']        = 'State';
    $contactmethods['address_zipcode']      = 'Zipcode';
    return $contactmethods;
   }
   add_filter('user_contactmethods','my_custom_userfields',10,1);

To display custom fields you can use one of the two methods listed below.

Option 1:

the_author_meta('facebook', $current_author->ID)

Option 2:

<?php $current_author = get_userdata(get_query_var('author')); ?>
<p><a href="<?php echo esc_url($current_author->contact_phone_office);?>" title="office_phone"> Office Phone</a></p>

管理メニューの順序をカスタマイズする

テスト済み: WordPress 3.0.1

このコードを使用すると、管理メニューの要素の順序を再編成できます.管理メニューの既存のリンクをクリックして、/wp-admin/URLの前にあるすべてのものをコピーするだけです.以下の順序は、新しい管理メニューの順序を表しています.

 // CUSTOMIZE ADMIN MENU ORDER
function custom_menu_order($menu_ord) {
    if (!$menu_ord)
        return true;
    return array(
     'index.php', // This represents the dashboard link
     'edit.php?post_type=events', // This is a custom post type menu
     'edit.php?post_type=news',
     'edit.php?post_type=articles',
     'edit.php?post_type=faqs',
     'edit.php?post_type=mentors',
     'edit.php?post_type=testimonials',
     'edit.php?post_type=services',
     'edit.php?post_type=page', // This is the default page menu
     'edit.php', // This is the default POST admin menu
 );
}
add_filter('custom_menu_order', 'custom_menu_order');
add_filter('menu_order', 'custom_menu_order');
 

Customize the order of the administration menu

Tested on: WordPress 3.0.1

This code will allow you to reorganize the order of elements in the administration menu. All that you need to do is click on an existing link in the administration menu and copy everything before the /wp-admin/ URL. The order below represents the order the new administration menu will have.

// CUSTOMIZE ADMIN MENU ORDER
function custom_menu_order($menu_ord) {
    if (!$menu_ord)
        return true;
    return array(
     'index.php', // This represents the dashboard link
     'edit.php?post_type=events', // This is a custom post type menu
     'edit.php?post_type=news',
     'edit.php?post_type=articles',
     'edit.php?post_type=faqs',
     'edit.php?post_type=mentors',
     'edit.php?post_type=testimonials',
     'edit.php?post_type=services',
     'edit.php?post_type=page', // This is the default page menu
     'edit.php', // This is the default POST admin menu
 );
}
add_filter('custom_menu_order', 'custom_menu_order');
add_filter('menu_order', 'custom_menu_order');

抜粋の長さを変更する関数

テスト対象: Wordpress 3.0.1

デフォルトでは、すべての抜粋は55語に制限されています.以下のコードを利用して、このデフォルト設定を上書きできます:

 function new_excerpt_length($length) { 
    return 100;
}

add_filter('excerpt_length', 'new_excerpt_length');
 

この例では、抜粋の長さを100ワードに変更しますが、同じ方法を使用して任意の値に変更できます.

Function to change the length of Exerpt

Tested on: Wordpress 3.0.1

By default all excerpts are capped at 55 words. Utilizing the code below you can override this default settings:

function new_excerpt_length($length) { 
    return 100;
}

add_filter('excerpt_length', 'new_excerpt_length');

This example changes the excerpt length to 100 words, but you can use the same method to change it to any value.

投稿/ページリストの管理にサムネイルを追加

これを関数に追加して、サムネイルプレビュー付きの新しい列を[投稿とページリストの管理/編集]に表示できます.

GZIP出力圧縮を有効にする

通常、サーバーはこれを自動的に行うように設定する必要がありますが、多くの共有ホストはこれを行いません(おそらくクライアントの帯域幅の使用量を増やすため).

  if(extension_loaded("zlib") && (ini_get("output_handler") != "ob_gzhandler"))
   add_action('wp', create_function('', '@ob_end_clean();@ini_set("zlib.output_compression", 1);'));
 

Enable GZIP output compression

Normally the server should be set up to do this automatically, but a lot of shared hosts don’t do this (probably to increase client bandwidth usage).

 if(extension_loaded("zlib") && (ini_get("output_handler") != "ob_gzhandler"))
   add_action('wp', create_function('', '@ob_end_clean();@ini_set("zlib.output_compression", 1);'));

DBクエリ、消費時間、メモリ消費量を表示する

テスト対象: WordPress 3.0.1

 function performance( $visible = false ) {

            get_num_queries(),
            timer_stop( 0, 3 ),
            memory_get_peak_usage() / 1024 / 1024
        );

    echo $visible ? $stat : "<!-- {$stat} -->" ;
}
 

次に、上記のコードの下にあるこのコードは、上記のコードを公開Webサイトのフッターに自動的に挿入します(テーマがwp_footerを呼び出していることを確認してください):

 add_action( 'wp_footer', 'performance', 20 );
 

複数回呼び出すことができます.

Display DB Queries, Time Spent and Memory Consumption

Tested on: WordPress 3.0.1

function performance( $visible = false ) {

    $stat = sprintf( '%d queries in %.3f seconds, using %.2fMB memory',
            get_num_queries(),
            timer_stop( 0, 3 ),
            memory_get_peak_usage() / 1024 / 1024
        );

    echo $visible ? $stat : "<!-- {$stat} -->" ;
}

Then this code below the code above which will automatically insert the code above into the footer of your public website (make sure your theme is calling wp_footer):

add_action( 'wp_footer', 'performance', 20 );

It can be called multiple times.

ライブサイトで使用するエラーデバッグとログを有効にする

これは、通常はデフォルトで無効になっているWP_DEBUG定数を使用するために作成したコードです.さて、WP_DEBUGを有効にして、マイナスの副作用なしにライブサイトで使用できるようにする方法を作成しただけでなく、他のデバッグ定数を使用して、エラーを強制的に表示したり、ログファイルを作成したりしました./wp-contentディレクトリ内のエラーと通知の一覧.

このコードをwp-config.phpファイルにドロップすると(バックアップを保存した後)、サイトの任意のURLの最後に?debug=1、2、または3パラメーターを渡すことができます.

?debug=1=すべてのエラー/通知を表示します ?debug=2=それらを強制的に表示します ?debug=3=/wp-contentdirにあるすべてのエラーのdebug.logファイルを作成します.

興味があれば、Comluvのために書いたゲスト投稿について詳しく説明します. http://comluv.com/dev/enable -debugging-and-logging-for-live-site-usage/

私はまだこれをパスワードで保護する方法、またはできれば何らかの方法でif(current_user_can( 'manage_themes')andis_logged_in())で機能させる方法に取り組んでいます.

しかし、それはもっとトリッキーになるところです.

Enable Error Debugging And Logging To Use On Live Sites

This is a piece of code I wrote to make use of the WP_DEBUG constants that are normally disabled by default. Well, I created a way to not only enable WP_DEBUG so you can use it on a live site with no negative side-effects, but I also made use of the other debugging constants for forcing errors to be displayed, and for creating a log file of the errors and Notices in the /wp-content directory.

Drop this code in your wp-config.php file (AFTER YOU SAVE A BACKUP JUST IN CASE) and then you can pass the ?debug=1, 2, or 3 parameters at the end of any URL on your site.

?debug=1 = shows all errors/notices ?debug=2 = forces them to be displayed ?debug=3 = creates a debug.log file of all errors in /wp-content dir.

I go into more detail on the guest post I wrote for Comluv if you're interested, here: http://comluv.com/dev/enable-debugging-and-logging-for-live-site-usage/

I'm still working on a way to make this either password protected, or preferrably somehow make it work on if (current_user_can('manage_themes') and is_logged_in().

But that's where it gets alot more tricky.

Automatically Add Dynamic Titles to Public Pages

Tested on: WordPress 3.0.1

Utilizing the code below will automatically create dynamic page titles based upon the pages/posts being viewed publicly.

/* Dynamic Titles **/
// This sets your <title> depending on what page you're on, for better formatting and for SEO
// You need to set the variable $longd to some custom text at the beginning of the function
function dynamictitles() {
    $longd = __('Enter your longdescription here.', 'texdomainstring');
        if ( is_single() ) {
          wp_title('');
          echo ' | '.get_bloginfo('name');

    } else if ( is_page() || is_paged() ) {

    } else if ( is_category() ) {
          bloginfo('name');
          wp_title(' | '.__('Archive for', 'texdomainstring'));

    } else if ( is_tag() ) {

新しい役割と機能-一度だけ実行してください！

私はこれらを手元に置いています.これはプラグインなしでそれらを行う正しい方法です.それらはオプションデータベースに単一のフィールド(prefix_user_roles)を設定し、それらを設定するためのプラグインは必要ありません. 利用可能な機能のリストとその機能の説明については、Codexページを参照してください. あなたこれらのブロックの1つをコメント解除し、任意のページを読み込んでから再度コメントするだけです！ここでは、必要な機能を備えた役割を作成しています:

 /* Capabilities */

// To add the new role, using 'international' as the short name and
// 'International Blogger' as the displayed name in the User list and edit page:
/*
add_role('international', 'International Blogger', array(
    'read' => true, // True allows that capability, False specifically removes it.
    'edit_posts' => true,
    'delete_posts' => true,
    'edit_published_posts' => true,
    'publish_posts' => true,
    'edit_files' => true,
    'import' => true,
    'upload_files' => true //last in array needs no comma!
));
*/


// To remove one outright or remove one of the defaults:
/* 
remove_role('international');
*/
 

既存の役割を削除して再度追加するよりも、既存の役割を追加/削除すると便利な場合があります. 繰り返しになりますが、コメントを解除し、ページをリロードしてから再度コメントするだけです.これにより、役割/機能がオプションテーブルに適切に保存されます. (これにより、開発者はそれらを制御し、同じことを行うかさばるプラグインのオーバーヘッドを取り除くことができます.)ここでは、作成者の役割を変更して、公開された投稿(デフォルト)を削除しますが、編集する機能を許可します公開された投稿(デフォルトではこのロールでは使用できません)-* add_cap *または* remove_cap *を使用します.

 /*
$edit_role = get_role('author');
   $edit_role->add_cap('edit_published_posts');
   $edit_role->remove_cap('delete_published_posts');
*/
 

このように変更するサイトのCodexページのグリッドを含むスプレッドシートを保持しているので、functions.phpファイルにコメントアウトされたコードを残しても、設定方法を思い出すことができます.これらの例をコメント化しないままにしないでください.コメントを付けないと、ページが読み込まれるたびにデータベースに書き込まれます.

New Roles and Capabilities - Only run once!

I keep these handy, this is the right way to do them without a plugin. They set a single field (prefix_user_roles) in the options database, and you don't need a plugin to set them. Refer to the Codex page for a list of what capabilities are available and descriptions for what they do. You only need to uncomment one of these blocks, load any page and then comment them again! Here I'm creating a role that's got the capabilities I need:

/* Capabilities */

// To add the new role, using 'international' as the short name and
// 'International Blogger' as the displayed name in the User list and edit page:
/*
add_role('international', 'International Blogger', array(
    'read' => true, // True allows that capability, False specifically removes it.
    'edit_posts' => true,
    'delete_posts' => true,
    'edit_published_posts' => true,
    'publish_posts' => true,
    'edit_files' => true,
    'import' => true,
    'upload_files' => true //last in array needs no comma!
));
*/


// To remove one outright or remove one of the defaults:
/* 
remove_role('international');
*/

It's sometimes handy to add/remove from an existing role rather than removing and re-adding one. Again, you only need to uncomment it, reload a page and then comment it again. This will store the role/capability properly in the options table. (This allows you, the developer to control them and removes the overhead of the bulky plugins that do the same thing.) Here I'm changing the author role to delete their published posts (the default), but allowing them the capability to edit their published posts (which isn't possible for this role by default)-- using *add_cap* or *remove_cap*.

/*
$edit_role = get_role('author');
   $edit_role->add_cap('edit_published_posts');
   $edit_role->remove_cap('delete_published_posts');
*/

I keep a spreadsheet with the grid from the Codex page for sites that modify this way, so I can remember how things are set, though leaving the commented out code in your functions.php file will work to. Don't leave these examples uncommented, or it will write to the database with each page load!

Wordpressカスタム管理フッター

//管理フッターテキストをカスタマイズします
関数custom_admin_footer(){
 echo 'カスタムフッターテキストとhtmlをここに追加します';
}
add_filter( 'admin_footer_text'、 'custom_admin_footer');

これをクライアントサイトに使用して、開発者として私に連絡するための簡単な参照ポイントとして使用します.

Wordpress Custom Admin Footer

// customize admin footer text
function custom_admin_footer() {

I use this for client sites as a simple point of reference to contact me as the dev.

RSSフィードを無効にする機能

テスト対象: Wordpress 3.0.1

Wordpressベースのウェブサイトを静的なものとして維持したい場合は、RSSフィードを無効にすることができます.

この機能を使用できます:

 function fb_disable_feed() {
wp_die( __('No feed available,please visit our <a href="'. get_bloginfo('url') .'">homepage</a>!') );
}

add_action('do_feed', 'fb_disable_feed', 1);
add_action('do_feed_rdf', 'fb_disable_feed', 1);
add_action('do_feed_rss', 'fb_disable_feed', 1);
add_action('do_feed_rss2', 'fb_disable_feed', 1);
add_action('do_feed_atom', 'fb_disable_feed', 1);
 

Function to Disable RSS Feeds

Tested on: Wordpress 3.0.1

You can disable RSS feeds If you want to maintain your Wordpress based website as static.

You can Use this function :

function fb_disable_feed() {
wp_die( __('No feed available,please visit our <a href="'. get_bloginfo('url') .'">homepage</a>!') );
}

add_action('do_feed', 'fb_disable_feed', 1);
add_action('do_feed_rdf', 'fb_disable_feed', 1);
add_action('do_feed_rss', 'fb_disable_feed', 1);
add_action('do_feed_rss2', 'fb_disable_feed', 1);
add_action('do_feed_atom', 'fb_disable_feed', 1);

「Howdy」メッセージを「Welcome」に変更します

この機能を使用すると、管理領域の右上にある「Howdy」メッセージをカスタマイズできます.
この関数は、JQueryを利用して、「Howdy」メッセージを「Welcome」に変更します.

 /****** Customize admin message "Howdy" to "Welcome" ******/
$nohowdy = "Welcome";

if (is_admin()) {
    add_action('init', 'artdev_nohowdy_h');
    add_action('admin_footer', 'artdev_nohowdy_f');
}
// Load jQuery
function artdev_nohowdy_h() {
    wp_enqueue_script('jquery');
}
// Modify
function artdev_nohowdy_f() {
global $nohowdy;
echo <<<JS
<script type="text/javascript">
//<![CDATA[
var nohowdy = "$nohowdy";
jQuery('#user_info p')
    .html(
    jQuery('#user_info p')
        .html()
        .replace(/Howdy/,nohowdy)
    );
//]]>
JS;
}
 

PHPバージョン、gettextフィルターを使用:

 add_filter('gettext', 'change_howdy', 10, 3);

function change_howdy($translated, $text, $domain) {

    if (!is_admin() || 'default' != $domain)
        return $translated;

    if (false !== strpos($translated, 'Howdy'))
        return str_replace('Howdy', 'Welcome', $translated);

    return $translated;
}
 

Change the "Howdy" message to "Welcome"

With this function you can customize the "Howdy" message in top right of your admin area.
This function make use of JQuery to change the "Howdy" message to "Welcome".

/****** Customize admin message "Howdy" to "Welcome" ******/
$nohowdy = "Welcome";

if (is_admin()) {
    add_action('init', 'artdev_nohowdy_h');
    add_action('admin_footer', 'artdev_nohowdy_f');
}
// Load jQuery
function artdev_nohowdy_h() {
    wp_enqueue_script('jquery');
}
// Modify
function artdev_nohowdy_f() {
global $nohowdy;
echo <<<JS
<script type="text/javascript">
//<![CDATA[
var nohowdy = "$nohowdy";
jQuery('#user_info p')
    .html(
    jQuery('#user_info p')
        .html()
        .replace(/Howdy/,nohowdy)
    );
//]]>
JS;
}

PHP version, using gettext filter:

add_filter('gettext', 'change_howdy', 10, 3);

function change_howdy($translated, $text, $domain) {

    if (!is_admin() || 'default' != $domain)
        return $translated;

    if (false !== strpos($translated, 'Howdy'))
        return str_replace('Howdy', 'Welcome', $translated);

    return $translated;
}

エディターのデフォルトをWYSIWYGまたはHTMLに設定

 function my_default_editor() {
    $r = 'tinymce'; // html or tinymce
    return $r;
}
add_filter( 'wp_default_editor', 'my_default_editor' );
 

HTMLエディタを削除する方法は次のとおりです

 jQuery(document).ready(function($) {
$("#edButtonHTML").remove();
});
 

更新 デフォルトのエディタをHTMLに設定する別の方法は次のとおりです

 add_filter('wp_default_editor', create_function('', 'return "html";'));
 

Set Editor Defaults to WYSIWYG or HTML

function my_default_editor() {
    $r = 'tinymce'; // html or tinymce
    return $r;
}
add_filter( 'wp_default_editor', 'my_default_editor' );

Here is how to remove the HTML Editor

jQuery(document).ready(function($) {
$("#edButtonHTML").remove();
});

UPDATED here is another way to set the default editor to HTML

add_filter('wp_default_editor', create_function('', 'return "html";'));

作成者メタボックス/オプションを削除＆amp;公開メタボックスに移動

テスト対象: Wordpress 3.0.1

私を夢中にさせるものの1つは、雑然としたWordpress管理エリアです.現在、functions.phpファイルで最初から常に設定している要素の1つは、作成者メタボックスと画面​​オプションを削除してから、公開メタボックスにオプションを追加することです.私の意見では、これは理にかなっていて、物事をきれいに保ちます.これは、該当する権限も尊重します.

この目標を達成するには、次のコードをコピーしてfunctions.phpファイルに貼り付けます.

これを行うためのより良い方法があると思われる場合は、提案してください.

注:コーディングの問題を修正するためにコードを更新しました

 // MOVE THE AUTHOR METABOX INTO THE PUBLISH METABOX
add_action( 'admin_menu', 'remove_author_metabox' );
add_action( 'post_submitbox_misc_actions', 'move_author_to_publish_metabox' );
function remove_author_metabox() {
    remove_meta_box( 'authordiv', 'post', 'normal' );
}
function move_author_to_publish_metabox() {
    global $post_ID;
    $post = get_post( $post_ID );
    echo '<div id="author" class="misc-pub-section" style="border-top-style:solid; border-top-width:1px; border-top-color:#EEEEEE; border-bottom-width:0px;">Author: ';
    post_author_meta_box( $post );
    echo '</div>';
}
 

Remove Author Metabox/Options & Move to Publish MetaBox

Tested on: Wordpress 3.0.1

One of the things that drive me crazy is a cluttered Wordpress Admin area. One of the elements which I now always setup from the start in my functions.php file is removing the Author MetaBox and Screen Options and then adding the option into the publish metabox. In my opinion this just makes sense and keep things clean. This also respects applicable permissions.

To achieve this goal, just copy and past the following code into your functions.php file.

If you feel there is a better way of doing this please suggest.

NOTE: UPDATED THE CODE TO FIX A CODING ISSUE

// MOVE THE AUTHOR METABOX INTO THE PUBLISH METABOX
add_action( 'admin_menu', 'remove_author_metabox' );
add_action( 'post_submitbox_misc_actions', 'move_author_to_publish_metabox' );
function remove_author_metabox() {
    remove_meta_box( 'authordiv', 'post', 'normal' );
}
function move_author_to_publish_metabox() {
    global $post_ID;
    $post = get_post( $post_ID );
    echo '<div id="author" class="misc-pub-section" style="border-top-style:solid; border-top-width:1px; border-top-color:#EEEEEE; border-bottom-width:0px;">Author: ';
    post_author_meta_box( $post );
    echo '</div>';
}

サーバーとサーバーをすばやく特定する環境の詳細

複数のサーバーと、開発、QA、本番環境などの複数の環境がある場合、これは非常に便利です.

私のシステムでは、環境はホスト名の最初の3文字で決まりますが、これはニーズに合わせて簡単に変更できます.

 add_action( 'admin_notices', 'report_environment_status', 3 );

// Report on which server and environment details
function report_environment_status() {
    $server = php_uname('n');
    switch (strtolower(substr($server,0,3))) {
        case 'pXX':
            $msg = "PRODUCTION";
            break;
        case 'qXX':
            $msg = "QA";
            break;
        case 'dXX':
            $msg = "DEVELOPMENT";
            break;
        default :
            $msg = 'UNKNOWN';
    }
    echo "<div id='update-nag'>";
    echo "<b>You are in the $msg environment. (Server: $server)</b>";
    echo "</div>";
}
 

これにより、間違った環境を更新する必要がなくなりました.

これをプラグインに変換し、ネットワークでアクティブ化して、すべてのサイトが通知を受け取るようにすることもできます.

Quickly Determine Server & Environment Details

If you have multiple servers and multiple environments such as development, QA, and production environments, this can be very useful.

For my systems, environment is determined by the first 3 letters of the hostname, but this could easily be changed to whatever suits your needs.

add_action( 'admin_notices', 'report_environment_status', 3 );

// Report on which server and environment details
function report_environment_status() {
    $server = php_uname('n');
    switch (strtolower(substr($server,0,3))) {
        case 'pXX':
            $msg = "PRODUCTION";
            break;
        case 'qXX':
            $msg = "QA";
            break;
        case 'dXX':
            $msg = "DEVELOPMENT";
            break;
        default :
            $msg = 'UNKNOWN';
    }
    echo "<div id='update-nag'>";
    echo "<b>You are in the $msg environment. (Server: $server)</b>";
    echo "</div>";
}

This has saved me many times from making updates to the wrong environment.

You can also turn this into a plugin and network activate it so all sites get the notification.

Requires at least 3.1 to work, though the meta_query could be replaced with the older meta_key and meta_value for 3.0.

Remove XML-RPC when not in use for performance boost

Tested on: Wordpress 3.0.1

WordPress uses a CURL operation to test for SSL capability for XML-RPC. If you're using XML-RPC but not using, then you can remove the filter. This is a small performance boost (since basically WP does a cURL GET on the https url and either 1) gets a denied message, or 2) times out, and it can take upwards of 5 seconds), but in our case it actually prevented a gateway timeout where a proxy was timing out before the cURL GET was timing out rendering XML-RPC unusable.

// Prevents WordPress from testing ssl capability on domain.com/xmlrpc.php?rsd
remove_filter('atom_service_url','atom_service_url_filter');

すべてのカスタムフィールドをグローバルに取得

 function get_custom_field($key, $echo = FALSE) {
    global $post;
    $custom_field = get_post_meta( $post->ID, $key, true );
    if ( $echo == false ) 
        return $custom_field;
    echo $custom_field;
}
 

次に、1行でフィールドを呼び出します

 <?php get_custom_field('custom-field-name', TRUE); ?>
 

Grab all custom fields globally

function get_custom_field($key, $echo = FALSE) {
    global $post;
    $custom_field = get_post_meta( $post->ID, $key, true );
    if ( $echo == false ) 
        return $custom_field;
    echo $custom_field;
}

Then call the field with a single line

<?php get_custom_field('custom-field-name', TRUE); ?>

コメントの数を返す

これはcount_user_posts()に似ていますが、代わりにコメントの数を返します:

 function count_user_comments($id) {
global $wpdb;
$users = $wpdb->get_var("
        SELECT COUNT( * ) AS total
        FROM $wpdb->comments
        WHERE comment_approved = 1 
        AND user_id = $id");
return $users;
}
 

詳細:ユーザーの投稿(カスタム投稿タイプを含む)またはコメントを数える:

 function atom_count($user_id, $what_to_count = 'post') {
  global $wpdb;    
  $where = $what_to_count == 'comment' ? "WHERE comment_approved = 1 AND user_id = {$user_id}" : get_posts_by_author_sql($what_to_count, TRUE, $user_id);
  $from = "FROM ".(($what_to_count == 'comment') ? $wpdb->comments : $wpdb->posts);    
  $count = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) {$from} {$where}"));
  return $count;
}
 

使用例:

<?php echo atom_count(1, 'movie'); // displays 'movie' post type count ?>

<?php echo atom_count(1, 'comment'); // displays comment count ?>

Return the number of comments

This is like count_user_posts(), but returns the number of comments instead:

function count_user_comments($id) {
global $wpdb;
$users = $wpdb->get_var("
        SELECT COUNT( * ) AS total
        FROM $wpdb->comments
        WHERE comment_approved = 1 
        AND user_id = $id");
return $users;
}

More: Count User's posts (including custom post types) or comments:

function atom_count($user_id, $what_to_count = 'post') {
  global $wpdb;    
  $where = $what_to_count == 'comment' ? "WHERE comment_approved = 1 AND user_id = {$user_id}" : get_posts_by_author_sql($what_to_count, TRUE, $user_id);
  $from = "FROM ".(($what_to_count == 'comment') ? $wpdb->comments : $wpdb->posts);    
  $count = $wpdb->get_var($wpdb->prepare("SELECT COUNT(*) {$from} {$where}"));
  return $count;
}

Usage examples:

<?php echo atom_count(1, 'movie'); // displays 'movie' post type count ?>

<?php echo atom_count(1, 'comment'); // displays comment count ?>

テキスト/HTMLウィジェットでoEmbedを有効にする

 add_filter( 'widget_text'、array($ wp_embed、 'run_shortcode')、8);
add_filter( 'widget_text'、array($ wp_embed、 'autoembed')、8); 

これはYouTubeのビデオウィジェットやFlickrのものに使用しています.

Post Word Count

Tested on: Wordpress 3.0.1

(Originally extracted from the Post Word Count plug-in by Nick Momrick)

Adds a count of total published words to the bottom of the "Right Now" box on the admin dashboard. Useful if you're using your blog as an outlet for something like NaNoWriMo or if you just want to keep track of how prolific your blogging skills have become.

function post_word_count() {
    $count = 0;
    $posts = get_posts( array(
        'numberposts' => -1,
        'post_type' => array( 'post', 'page' )
    ));
    foreach( $posts as $post ) {
        $count += str_word_count( strip_tags( get_post_field( 'post_content', $post->ID )));
    }
    $num =  number_format_i18n( $count );
    // This block will add your word count to the stats portion of the Right Now box
    $text = _n( 'Word', 'Words', $num );
    echo "<tr><td class='first b'>{$num}</td><td class='t'>{$text}</td></tr>";
    // This line will add your word count to the bottom of the Right Now box.
    echo '<p>This blog contains a total of <strong>' . $num . '</strong> published words!</p>';
}

// add to Content Stats table
add_action( 'right_now_content_table_end', 'post_word_count');
// add to bottom of Activity Box
add_action('activity_box_end', 'post_word_count');

Kudos to Rarst for the query-free cleanup of the code!

    wp_print_scripts('my_script');
}
    return $posts;
}
add_action('the_posts', 'has_my_shortcode');
 

特定のウィジェットが存在する場合にのみスクリプトをロードする方法は次のとおりです

ウィジェットがロードされるページにのみスクリプトをロードするには、ウィジェットクラスにis_active_widget()コードを追加する必要があります.たとえば、デフォルトの最近のコメントウィジェット(wp-includes/default-widgets.php、行602)を参照してください:

 class WP_Widget_Recent_Comments extends WP_Widget {
    function WP_Widget_Recent_Comments() {
        $widget_ops = array('classname' => 'widget_recent_comments', 'description' => __( 'The most recent comments' ) );
        $this->WP_Widget('recent-comments', __('Recent Comments'), $widget_ops);
        $this->alt_option_name = 'widget_recent_comments';
        if ( is_active_widget(false, false, $this->id_base) )
        add_action( 'wp_head', array(&$this, 'recent_comments_style') );
        add_action( 'comment_post', array(&$this, 'flush_widget_cache') );
        add_action( 'transition_comment_status', array(&$this, 'flush_widget_cache') );
    }
 

Loading scripts conditionally

Here is a way to load scripts only if a particular shortcode or widget is present. source: Loading scripts only if a particular shortcode or widget is present

function has_my_shortcode($posts) {
    if ( empty($posts) )
        return $posts;
    $found = false;
    foreach ($posts as $post) {
        if ( stripos($post->post_content, '[my_shortcode') )
            $found = true;
            break;
        }
    if ($found){
        $urljs = get_bloginfo( 'template_directory' ).IMP_JS;
    wp_register_script('my_script', $urljs.'myscript.js' );
    wp_print_scripts('my_script');
}
    return $posts;
}
add_action('the_posts', 'has_my_shortcode');

And here is how to load scripts only if a certain widget is present

To load the script in the page where the widget is loaded only, you will have to add the is_active_widget() code, in you widget class. E.g., see the default recent comments widget (wp-includes/default-widgets.php, line 602):

class WP_Widget_Recent_Comments extends WP_Widget {
    function WP_Widget_Recent_Comments() {
        $widget_ops = array('classname' => 'widget_recent_comments', 'description' => __( 'The most recent comments' ) );
        $this->WP_Widget('recent-comments', __('Recent Comments'), $widget_ops);
        $this->alt_option_name = 'widget_recent_comments';
        if ( is_active_widget(false, false, $this->id_base) )
        add_action( 'wp_head', array(&$this, 'recent_comments_style') );
        add_action( 'comment_post', array(&$this, 'flush_widget_cache') );
        add_action( 'transition_comment_status', array(&$this, 'flush_widget_cache') );
    }

カスタムダッシュボードCSS

 /* Change WordPress dashboard CSS */
function custom_admin_styles() {
    echo '<style type="text/css">#wphead{background:#069}</style>';
}
add_action('admin_head', 'custom_admin_styles');
 

タグ間のCSSに変更を加えることができます.

/* Change WordPress dashboard CSS */
function custom_admin_styles() {
    echo '<style type="text/css">#wphead{background:#069}</style>';

親ページのスラグをbody_classに追加

 /***************************************************************
* Function body_class_section
* Add the top level page to the body class for coloured sections

add_filter('body_class','body_class_section');

function body_class_section($classes) {
    global $wpdb, $post;
    if (is_page()) {
        if ($post->post_parent) {
            $parent  = end(get_post_ancestors($current_page_id));
        } else {
            $parent = $post->ID;
        }
        $post_data = get_post($parent, ARRAY_A);
        $classes[] = 'section-' . $post_data['post_name'];
    }
    return $classes;
}
 

このフィルターは、現在のページの最上位の親に基づいて一意のボディクラスを追加します.これは、サイトのセクションごとに特定の色やレイアウトがあるサイトに使用します.これは、ページに基づいたサイトで最適に機能します. CSSの例:

 .section-about { background: red; }
.section-portfolio { background: blue; }
 

テーマでは、body_class関数も使用する必要があります.

oEmbedフラッシュオブジェクトを修正

 /***************************************************************
* Function my_oembed_wmode
* Fix oEmbed window mode for flash objects
***************************************************************/

add_filter('embed_oembed_html', 'my_oembed_wmode', 1);

function my_oembed_wmode( $embed ) {
    if ( strpos( $embed, '<param' ) !== false ) {
        $embed = str_replace( '<embed', '<embed wmode="transparent" ', $embed );
        $embed = preg_replace( '/param>/', 'param><param name="wmode" value="transparent" />', $embed, 1);
    }
    return $embed;
}
 

過去に、oEmbedFlashオブジェクトがドロップダウンナビゲーションメニューと衝突するという問題が発生しました.このフィルターは、埋め込みに透過ウィンドウモードを追加することで、この問題を修正します.

管理ページリストから「コメント」列を削除します

 /***************************************************************
* Function custom_pages_columns
* Remove "comments" from pages overview (rarely use comments on pages)

add_filter('manage_pages_columns', 'custom_pages_columns');

function custom_pages_columns($defaults) {
    unset($defaults['comments']);
    return $defaults;
}
 

ページへのコメントを利用することはほとんどありません.これにより、WordPressダッシュボードの整理に役立ちます.

Add parent page slug to body_class

/***************************************************************
* Function body_class_section
* Add the top level page to the body class for coloured sections
***************************************************************/

add_filter('body_class','body_class_section');

function body_class_section($classes) {
    global $wpdb, $post;
    if (is_page()) {
        if ($post->post_parent) {
            $parent  = end(get_post_ancestors($current_page_id));
        } else {
            $parent = $post->ID;
        }
        $post_data = get_post($parent, ARRAY_A);
        $classes[] = 'section-' . $post_data['post_name'];
    }
    return $classes;
}

This filter adds a unique body class based on the highest level parent of the current page. I use this for sites that have specific colours or layouts for each section of the site. It works best with sites based around pages. CSS examples:

.section-about { background: red; }
.section-portfolio { background: blue; }

Your theme must also make use of the body_class function.

Fix oEmbed flash objects

/***************************************************************
* Function my_oembed_wmode
* Fix oEmbed window mode for flash objects
***************************************************************/

add_filter('embed_oembed_html', 'my_oembed_wmode', 1);

function my_oembed_wmode( $embed ) {
    if ( strpos( $embed, '<param' ) !== false ) {
        $embed = str_replace( '<embed', '<embed wmode="transparent" ', $embed );
        $embed = preg_replace( '/param>/', 'param><param name="wmode" value="transparent" />', $embed, 1);
    }
    return $embed;
}

I have had problems in the past where oEmbed Flash objects collide with drop down navigation menus. This filter fixes that problem by adding a transparent window mode to the embeds.

Remove the "comments" column from Admin page list

/***************************************************************
* Function custom_pages_columns
* Remove "comments" from pages overview (rarely use comments on pages)
***************************************************************/

add_filter('manage_pages_columns', 'custom_pages_columns');

function custom_pages_columns($defaults) {
    unset($defaults['comments']);
    return $defaults;
}

I hardly ever make use of commenting on pages and this helps keep things tidy in the WordPress dashboard.

            continue;
        return true;
    }
    return false;
}
 

投稿にタグが付いているかどうかを確認するのと同じ方法でこの関数を使用します.

 if( has_embed() ) {
   // do whatever
}
 

関数は、埋め込みが見つかった場合はtrueを返し、失敗した場合はfalseを返します.

Check if a post has embedded content.

Check if a post has embedded content, works inside the loop using the current post's ID, or alternatively can be passed an ID to determine the post to check for embedded content.

function has_embed( $post_id = false ) {
    if( !$post_id ) $post_id = get_the_ID();
    else $post_id = absint( $post_id );
    if( !$post_id ) return false;

    $post_meta = get_post_custom_keys( $post_id );
    $post_meta = array_map( 'trim' , $post_meta );

    foreach( $post_meta as $meta ) {
        if( '_oembed' != substr( $meta , 0 , 7 ) )
            continue;
        return true;
    }
    return false;
}

You'd use the function in the same way you check if a post has a tag..

if( has_embed() ) {
   // do whatever
}

Function returns true if an embed is found, false on fail.

ホームページにさまざまなカスタム投稿タイプの投稿を表示する

この投稿の下部にある次のコードをfunctions.phpファイルにドロップすることで、wordpressに、作成したさまざまなカスタム投稿タイプの投稿を自動的に表示させることができます.現在、デフォルトのワードプレスは、デフォルトの「投稿」に属する投稿のみを表示します.投稿タイプ.

以下の例では、以下を呼び出すセクションを変更する必要があります.

 $query->set( 'post_type', array('post', 'page', 'services', 'attachment'));
 

ホームページの投稿リストの結果に含めたい独自のカスタム投稿タイプを使用します.この場合、デフォルトの「投稿」に属するすべての投稿を返送するようにワードプレスに依頼しています.および「ページ」post_typeは、「サービス」用に作成したカスタム投稿タイプも含めるようにワードプレスに要求します.そして最後に、デフォルトのワードプレス投稿タイプ「添付ファイル」つまり、メディアライブラリに何かが追加されると、ホームページに別のエントリとして自動的に表示されます.

 // CUSTOM HOMEPAGE POST LIST INCLUDING DIFFERENT POST_TYPES
// make sure to edit the post types you wanted included in the list below
add_filter( 'pre_get_posts', 'my_homepage_post_list' );
function my_homepage_post_list ( $query ) {
    if ( is_home() && false == $query->query_vars['suppress_filters'] )
        $query->set( 'post_type', array('post', 'page', 'services', 'attachment'));
    return $query;
}
 

このカスタムクエリは、次のようなカスタムフィードなど、さまざまな場所で利用することもできます

 if (( is_home() && false == $query->query_vars['suppress_filters'] ) || is_feed())
 

Display Posts from Different Custom Post Types on homepage

By dropping the following code on the bottom of this post into your functions.php file you can get wordpress to automatically display posts from different custom post types you have created. Currently by default wordpress only display posts which belong to the default "posts" post type.

In the example provided below you will need to change the section which calls:

$query->set( 'post_type', array('post', 'page', 'services', 'attachment'));

With your own custom post types which you would like to include in the homepage post list results. In this case we are asking wordpress to return to us all posts belonging to the default "post" and "page" post_type then asking wordpress to also include the custom post type we created for "services" and finally the default wordpress post type of "attachment" which just means that anytime something is added to the media library it will automatically get displayed on the homepage as a separate entry.

// CUSTOM HOMEPAGE POST LIST INCLUDING DIFFERENT POST_TYPES
// make sure to edit the post types you wanted included in the list below
add_filter( 'pre_get_posts', 'my_homepage_post_list' );
function my_homepage_post_list ( $query ) {
    if ( is_home() && false == $query->query_vars['suppress_filters'] )
        $query->set( 'post_type', array('post', 'page', 'services', 'attachment'));
    return $query;
}

You can also utilize this custom query in different locations, such as in a custom feed through something like this

if (( is_home() && false == $query->query_vars['suppress_filters'] ) || is_feed())

デフォルトフィールドの連絡先情報ユーザープロファイルを削除し、より使いやすいものに置き換えます

この関数の2番目の部分についてはすでに説明しましたが、デフォルトのフィールド(AIM、Yahoo IM、Jabber/Google Talk)はまだ削除されていません:

 function update_contact_methods( $contactmethods ) {

// Remove annoying and unwanted default fields  
unset($contactmethods['aim']);  
unset($contactmethods['jabber']);  
unset($contactmethods['yim']);  

// Add new fields  
$contactmethods['phone'] = 'Phone';  
$contactmethods['mobile'] = 'Mobile';  
$contactmethods['address'] = 'Address';  

return $contactmethods;
}
add_filter('user_contactmethods', 'update_contact_methods');
 

もちろん、[新しいフィールドの追加]の下に必要な数のフィールドを追加できます(このスレッドの前半の例を参照)

Remove default fields contact info user profile and replace them with something more usable

The second part of this function has already been mentioned above, but removing the default fields - AIM, Yahoo IM and Jabber/Google Talk - not yet:

function update_contact_methods( $contactmethods ) {

// Remove annoying and unwanted default fields  
unset($contactmethods['aim']);  
unset($contactmethods['jabber']);  
unset($contactmethods['yim']);  

// Add new fields  
$contactmethods['phone'] = 'Phone';  
$contactmethods['mobile'] = 'Mobile';  
$contactmethods['address'] = 'Address';  

return $contactmethods;
}
add_filter('user_contactmethods', 'update_contact_methods');

Of course you can add as many fields as you want (see previous examples earlier in this thread) under "Add new fields"

投稿タイプの事前入力

これがこのコレクションの1つです.

 ////////////////////////////////////////////////////////////////////////////////////
// This auto populates post types and posts.
///////////////////////////////////////////////////////////////////////////////////

add_filter( 'default_content', 'my_editor_content' );

function my_editor_content( $content ) {

    global $post_type;

    switch( $post_type ) {
        case 'your_post_type_here': //auto populate
            $content = 'The content you want to pre-populate the post type with.';
break;
     }

    return $content;
}
 

これは、わずかな違いを除いて同じ情報を何度も投稿する必要がある場合に便利です.

Pre-populating post types

Here is one for this collection.

////////////////////////////////////////////////////////////////////////////////////
// This auto populates post types and posts.
///////////////////////////////////////////////////////////////////////////////////

add_filter( 'default_content', 'my_editor_content' );

function my_editor_content( $content ) {

    global $post_type;

    switch( $post_type ) {
        case 'your_post_type_here': //auto populate
            $content = 'The content you want to pre-populate the post type with.';
break;
     }

    return $content;
}

This can come in handy for when you need to post the same info over and over again with slight differences.

Googleアナリティクスコードを自動的に含める

テスト対象: Wordpress 3.1 RC3

WordPress 2.3.0以降、すべてのサイトでこのスクリプトを使用しています...標準のGoogleトラッキングスクリプトをフッターに追加するだけです.

 // Add Google Analytics Tracking Code
function add_google_analytics() {
?>
<script type="text/javascript">
    var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
    document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
    try {
        var pageTracker = _gat._getTracker("UA-XXXXXXX-X");
        pageTracker._trackPageview();
    } catch(err) {}</script>
<?php
}

add_action('wp_footer', 'add_google_analytics');
 

必ずUA-XXXXXXX-Xを独自のGoogleトラッキングコードに置き換えてください...

Auto Include Google Analytics Code

Tested on: Wordpress 3.1 RC3

I've been using this script on all of my sites since WordPress 2.3.0 ... it just adds the standard Google tracking scripts to the footer.

// Add Google Analytics Tracking Code
function add_google_analytics() {
?>
<script type="text/javascript">
    var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
    document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
    try {
        var pageTracker = _gat._getTracker("UA-XXXXXXX-X");
        pageTracker._trackPageview();
    } catch(err) {}</script>
<?php
}

add_action('wp_footer', 'add_google_analytics');

Just be sure to replace UA-XXXXXXX-X with your own Google tracking code...

情報とデバッグのためにすべての定数を一覧表示します

テスト対象: Wordpress 3.0.1

ログインしているユーザーの場合にのみ情報が表示されます

 if ( is_user_logged_in() ) {
    print('<pre>');
    print_r( @get_defined_constants() );
    print('</pre>');
}
 

定数の名前と値に部分的に一致するオプションのフィルターを備えたバージョンは次のとおりです.

 function constants($filter = false) {

        $constants = get_defined_constants();

        if( $filter ) {

            $temp = array();

            foreach ( $constants as $key => $constant )
                if( false !== stripos( $key, $filter ) || false !== stripos( $constant, $filter ) )
                    $temp[$key] = $constant;

            $constants = $temp;
        }

        ksort( $constants );
        var_dump( $constants );
    }
 

List all constants for information and debugging

Tested on: Wordpress 3.0.1

Will only display the information if you are a logged in user

if ( is_user_logged_in() ) {
    print('<pre>');
    print_r( @get_defined_constants() );
    print('</pre>');
}

Here is version with optional filter that will partially match constant names and values:

function constants($filter = false) {

        $constants = get_defined_constants();

        if( $filter ) {

            $temp = array();

            foreach ( $constants as $key => $constant )
                if( false !== stripos( $key, $filter ) || false !== stripos( $constant, $filter ) )
                    $temp[$key] = $constant;

            $constants = $temp;
        }

        ksort( $constants );
        var_dump( $constants );
    }

ローカルホストにauto-update/plugin-installerを追加

 define ('FS_METHOD', 'direct');
 

これをwp-config.phpに入れてください.

Add auto-update/plugin-installer on you localhost

define ('FS_METHOD', 'direct');

Put this in your wp-config.php.

デフォルトの作成者スラッグを変更

これを関数に入れて、デフォルトの作成者スラグを好きなように変更します.
「売り手」を必要なスラッグに変更するだけです.

 // Change URL Slug from Author to Sellers
function new_author_base() {
    global $wp_rewrite;
    $author_slug = 'sellers';
    $wp_rewrite->author_base = $author_slug;
}
add_action('init', 'new_author_base');
 

Change default Author Slug

Put this in your functions to change the default Author Slug to whatever you want,
just change the "sellers" to the slug you want.

// Change URL Slug from Author to Sellers
function new_author_base() {
    global $wp_rewrite;
    $author_slug = 'sellers';
    $wp_rewrite->author_base = $author_slug;
}
add_action('init', 'new_author_base');

WYSIYG-editorに[次のページ]ボタンを追加

 add_filter('mce_buttons','wysiwyg_editor');
function wysiwyg_editor($mce_buttons) {
    $pos = array_search('wp_more',$mce_buttons,true);
    if ($pos !== false) {
        $tmp_buttons = array_slice($mce_buttons, 0, $pos+1);
        $tmp_buttons[] = 'wp_page';
        $mce_buttons = array_merge($tmp_buttons, array_slice($mce_buttons, $pos+1));
    }
    return $mce_buttons;
}
 

Add "Next-page"-button in WYSIYG-editor

add_filter('mce_buttons','wysiwyg_editor');
function wysiwyg_editor($mce_buttons) {
    $pos = array_search('wp_more',$mce_buttons,true);
    if ($pos !== false) {
        $tmp_buttons = array_slice($mce_buttons, 0, $pos+1);
        $tmp_buttons[] = 'wp_page';
        $mce_buttons = array_merge($tmp_buttons, array_slice($mce_buttons, $pos+1));
    }
    return $mce_buttons;
}

TinyMCEエディターにカスタムスタイルを追加

ユーザーとクライアントは、コンテンツがエディターでどのように表示されるのか、フロントエンドでどのように表示されるのかについて混乱することがあります.メインのスタイルシートから新しいtinymce.cssに関連する数行をコピーすると、非常に役立ちます.

 function custom_mce_css($wp) {
    return $wp .= ',' . get_bloginfo('stylesheet_directory') . '/css/tinymce.css';
}
add_filter( 'mce_css', 'custom_mce_css' );
 

Add custom styles to TinyMCE editor

Sometimes users and clients get confused about how their content is displayed in the editor versus how it is displayed on the front-end. Copying just a few relevant lines from your main stylesheet into your new tinymce.css can help a lot:

function custom_mce_css($wp) {
    return $wp .= ',' . get_bloginfo('stylesheet_directory') . '/css/tinymce.css';
}
add_filter( 'mce_css', 'custom_mce_css' );
