カスタム投稿タイプのカテゴリを表示するにはどうすればよいですか？

カスタム投稿タイプがあります.私がやりたいのは、プロジェクトのすぐ上にプロジェクトカテゴリを表示して、訪問者がそれに応じてプロジェクトをフィルタリングできるようにすることです.

私のfunctions.phpには次のものがあります:

 <?php

require_once('portfolio-type.php');
add_filter('excerpt_length', 'my_excerpt_length');

function my_excerpt_length($length) {
return 25; 
}

add_filter('excerpt_more', 'new_excerpt_more');  
function new_excerpt_more($text){  

return ' ';  
}  

function portfolio_thumbnail_url($pid){
$image_id = get_post_thumbnail_id($pid);  
$image_url = wp_get_attachment_image_src($image_id,'screen-shot');  
return  $image_url[0];  
}
?>

portfolio-type.php内:

  <?php

 if ( function_exists( 'add_theme_support' ) ) { 
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 270, 170, true ); // Normal post thumbnails
add_image_size( 'screen-shot', 720, 540 ); // Full size screen
 }

 add_action('init', 'portfolio_register');  

 function portfolio_register() {  
 $args = array(  
    'label' => __('Portfolio'),  
    'singular_label' => __('Project'),  
    'public' => true,  
    'show_ui' => true,  
    'capability_type' => 'post',  
    'hierarchical' => false,  
    'rewrite' => true,  
    'supports' => array('title', 'editor', 'thumbnail')  
   );  

register_post_type( 'portfolio' , $args );  
 }  

register_taxonomy("project-type", array("portfolio"), array("hierarchical"  =>  true, "label" => "Project Types", "singular_label" => "Project Type",   "rewrite" => true));
 ?>

そして最後に私のindex.phpに私は持っています:

 <!-- Start Projects -->

                    <div id="posts" class="row isotope">

                      <?php if (have_posts()) : while (have_posts()) : the_post(); ?>  

                          <?php  
                              $title= str_ireplace('"', '', trim(get_the_title()));  
                              $desc= str_ireplace('"', '', trim(get_the_content()));  
                          ?>     

                          <div class="item post item span4 isotope-item">

                            <a class="project-wrp fancybox" title="<?=$title?>" rel="lightbox[work]" href="<?php print portfolio_thumbnail_url($post->ID) ?>"><div class="profile-photo"><div class="profile-icon">&#0102;</div><?php the_post_thumbnail(array('230','170'),array('alt' => '')); ?> </div>  
                            <div class="project-name"><?php echo $title; ?></div>
                            <div class="project-client"><?php echo $desc; ?></div>
                            </a>
                          </div>  
                      <?php endwhile; endif; ?>  


                    </div>

I have a custom post type. What I'd like to do is to display the project categories just on top of the projects so visitors could then filter projects accordingly.

In my functions.php I have:

<?php

require_once('portfolio-type.php');
add_filter('excerpt_length', 'my_excerpt_length');

function my_excerpt_length($length) {
return 25; 
}

add_filter('excerpt_more', 'new_excerpt_more');  
function new_excerpt_more($text){  

return ' ';  
}  

function portfolio_thumbnail_url($pid){
$image_id = get_post_thumbnail_id($pid);  
$image_url = wp_get_attachment_image_src($image_id,'screen-shot');  
return  $image_url[0];  
}
?>

In portfolio-type.php:

 <?php

 if ( function_exists( 'add_theme_support' ) ) { 
add_theme_support( 'post-thumbnails' );
set_post_thumbnail_size( 270, 170, true ); // Normal post thumbnails
add_image_size( 'screen-shot', 720, 540 ); // Full size screen
 }

 add_action('init', 'portfolio_register');  

 function portfolio_register() {  
 $args = array(  
    'label' => __('Portfolio'),  
    'singular_label' => __('Project'),  
    'public' => true,  
    'show_ui' => true,  
    'capability_type' => 'post',  
    'hierarchical' => false,  
    'rewrite' => true,  
    'supports' => array('title', 'editor', 'thumbnail')  
   );  

register_post_type( 'portfolio' , $args );  
 }  

register_taxonomy("project-type", array("portfolio"), array("hierarchical"  =>  true, "label" => "Project Types", "singular_label" => "Project Type",   "rewrite" => true));
 ?>

And finally in my index.php I have:

<!-- Start Projects -->

                    <div id="posts" class="row isotope">

                      <?php if (have_posts()) : while (have_posts()) : the_post(); ?>  

                          <?php  
                              $title= str_ireplace('"', '', trim(get_the_title()));  
                              $desc= str_ireplace('"', '', trim(get_the_content()));  
                          ?>     

                          <div class="item post item span4 isotope-item">

                            <a class="project-wrp fancybox" title="<?=$title?>" rel="lightbox[work]" href="<?php print portfolio_thumbnail_url($post->ID) ?>"><div class="profile-photo"><div class="profile-icon">&#0102;</div><?php the_post_thumbnail(array('230','170'),array('alt' => '')); ?> </div>  
                            <div class="project-name"><?php echo $title; ?></div>
                            <div class="project-client"><?php echo $desc; ?></div>
                            </a>
                          </div>  
                      <?php endwhile; endif; ?>  


                    </div>

このポートフォリオの投稿カテゴリリストの用途:

 <?php echo get_the_term_list(get_the_ID(), 'portfolio_category', '', ', ', ''); ?>

For this portfolio post categories list use:

<?php echo get_the_term_list(get_the_ID(), 'portfolio_category', '', ', ', ''); ?>

投稿タイプと分類法を登録するportfolio-type.phpからコードを削除します(9行目以降).

次のコード(portfolio-type.php内)を使用して、投稿タイプ「portfolio」を登録します

 function portfolio_register() {
    $labels = array(
        'name' => _x('Portfolio', 'post type general name'),
        'singular_name' => _x('Portfolio Item', 'post type singular name'),
        'add_new' => _x('Add New', 'portfolio item'),
        'add_new_item' => __('Add New Portfolio Item'),
        'edit_item' => __('Edit Portfolio Item'),
        'new_item' => __('New Portfolio Item'),
        'view_item' => __('View Portfolio Item'),
        'search_items' => __('Search Portfolio Items'),
        'not_found' =>  __('Nothing found'),
        'not_found_in_trash' => __('Nothing found in Trash'),
        'parent_item_colon' => ''
    );
    $args = array(
        'labels' => $labels,
        'public' => true,
        'publicly_queryable' => true,
        'show_ui' => true,
        'query_var' => true,
        'rewrite' => true,
        'capability_type' => 'post',
        'hierarchical' => false,
        'menu_position' => 8,
        'supports' => array('title','editor','thumbnail')
    ); 
    register_post_type( 'portfolio' , $args );
}
add_action('init', 'portfolio_register');

次のコード(portfolio-type.php内)を使用して、投稿タイプ「portfolio」の分類法「portfolio_categories」を登録し、階層化(カテゴリなど)します

 function create_portfolio_taxonomies() {
    $labels = array(
        'name'              => _x( 'Categories', 'taxonomy general name' ),
        'singular_name'     => _x( 'Category', 'taxonomy singular name' ),
        'search_items'      => __( 'Search Categories' ),
        'all_items'         => __( 'All Categories' ),
        'parent_item'       => __( 'Parent Category' ),
        'parent_item_colon' => __( 'Parent Category:' ),
        'edit_item'         => __( 'Edit Category' ),
        'update_item'       => __( 'Update Category' ),
        'add_new_item'      => __( 'Add New Category' ),
        'new_item_name'     => __( 'New Category Name' ),
        'menu_name'         => __( 'Categories' ),
    );

    $args = array(
        'hierarchical'      => true, // Set this to 'false' for non-hierarchical taxonomy (like tags)
        'labels'            => $labels,
        'show_ui'           => true,
        'show_admin_column' => true,
        'query_var'         => true,
        'rewrite'           => array( 'slug' => 'categories' ),
    );

    register_taxonomy( 'portfolio_categories', array( 'portfolio' ), $args );
}
add_action( 'init', 'create_portfolio_taxonomies', 0 );

次に、次のコードを使用して、テンプレートファイル(index.phpなど)の分類用語を取得します

 <?php

$taxonomy = 'portfolio_categories';
$terms = get_terms($taxonomy); // Get all terms of a taxonomy

if ( $terms && !is_wp_error( $terms ) ) :
?>
    <ul>
        <?php foreach ( $terms as $term ) { ?>
            <li><a href="<?php echo get_term_link($term->slug, $taxonomy); ?>"><?php echo $term->name; ?></a></li>
        <?php } ?>
    </ul>
<?php endif;?>

?>

説明が必要な場合はお知らせください.

Remove your code from portfolio-type.php that registers post type and taxonomy (line 9 onwards).

Use the following code (in portfolio-type.php) to register the post type "portfolio"

function portfolio_register() {
    $labels = array(
        'name' => _x('Portfolio', 'post type general name'),
        'singular_name' => _x('Portfolio Item', 'post type singular name'),
        'add_new' => _x('Add New', 'portfolio item'),
        'add_new_item' => __('Add New Portfolio Item'),
        'edit_item' => __('Edit Portfolio Item'),
        'new_item' => __('New Portfolio Item'),
        'view_item' => __('View Portfolio Item'),
        'search_items' => __('Search Portfolio Items'),
        'not_found' =>  __('Nothing found'),
        'not_found_in_trash' => __('Nothing found in Trash'),
        'parent_item_colon' => ''
    );
    $args = array(
        'labels' => $labels,
        'public' => true,
        'publicly_queryable' => true,
        'show_ui' => true,
        'query_var' => true,
        'rewrite' => true,
        'capability_type' => 'post',
        'hierarchical' => false,
        'menu_position' => 8,
        'supports' => array('title','editor','thumbnail')
    ); 
    register_post_type( 'portfolio' , $args );
}
add_action('init', 'portfolio_register');

Use the following code (in portfolio-type.php) to register a taxonomy "portfolio_categories" for the post type "portfolio", make it hierarchical (like categories)

function create_portfolio_taxonomies() {
    $labels = array(
        'name'              => _x( 'Categories', 'taxonomy general name' ),
        'singular_name'     => _x( 'Category', 'taxonomy singular name' ),
        'search_items'      => __( 'Search Categories' ),
        'all_items'         => __( 'All Categories' ),
        'parent_item'       => __( 'Parent Category' ),
        'parent_item_colon' => __( 'Parent Category:' ),
        'edit_item'         => __( 'Edit Category' ),
        'update_item'       => __( 'Update Category' ),
        'add_new_item'      => __( 'Add New Category' ),
        'new_item_name'     => __( 'New Category Name' ),
        'menu_name'         => __( 'Categories' ),
    );

    $args = array(
        'hierarchical'      => true, // Set this to 'false' for non-hierarchical taxonomy (like tags)
        'labels'            => $labels,
        'show_ui'           => true,
        'show_admin_column' => true,
        'query_var'         => true,
        'rewrite'           => array( 'slug' => 'categories' ),
    );

    register_taxonomy( 'portfolio_categories', array( 'portfolio' ), $args );
}
add_action( 'init', 'create_portfolio_taxonomies', 0 );

Then use the following code to retrieve taxonomy terms in template files (like index.php)

<?php

$taxonomy = 'portfolio_categories';
$terms = get_terms($taxonomy); // Get all terms of a taxonomy

if ( $terms && !is_wp_error( $terms ) ) :
?>
    <ul>
        <?php foreach ( $terms as $term ) { ?>
            <li><a href="<?php echo get_term_link($term->slug, $taxonomy); ?>"><?php echo $term->name; ?></a></li>
        <?php } ?>
    </ul>
<?php endif;?>

?>

Let me know if you need any clarification.

Portfolio-type.phpのコードを指定したコードに置き換えたところ、カテゴリが表示されましたが、何らかの理由でプロジェクトがフィルタリングされていません.

I replaced the code in my portfolio-type.php with the code you provided and I got the categories to show up but they're not filtering the projects for some reason.

私が提供した最初の2つのコードスニペットは、バックエンド機能用でした.私が提供した3番目のスニペットでは、カテゴリ名を取得できます. もう一度あなたのウェブサイトを見て、あなたが今欠けているものを見てみましょう.

The first two code snippets I provided was for the back-end functionality. The third snippet I provided allows you to retrieve the category names. Let me go through your website again and see what you are missing now.

あなたが今持っているphpコード(ポートフォリオセクション全体)を投稿することは可能でしょうか?

Would it be possible for you to post the php code (for the whole portfolio section) you have now?

これは、カスタム分類法 `function displayCategories($post_type_name){を設定した後にカテゴリをロードするためのより良い方法かもしれません. $ customPostTaxonomies=get_object_taxonomies($post_type_name); if(count($ customPostTaxonomies)> 0){ foreach($ customPostTaxonomies as $tax){ $ args=array( 'orderby'=> '名前'、 'show_count'=> 1、 'pad_counts'=> 0、 '階層'=> 1、 '分類法'=> $tax、 'title_li'=> '' ); wp_list_categories($ args); } } } `

This might be a better way to load the categories after setting up the custom taxonomy `function displayCategories($post_type_name) { $customPostTaxonomies = get_object_taxonomies($post_type_name); if(count($customPostTaxonomies) > 0) { foreach($customPostTaxonomies as $tax) { $args = array( 'orderby' => 'name', 'show_count' => 1, 'pad_counts' => 0, 'hierarchical' => 1, 'taxonomy' => $tax, 'title_li' => '' ); wp_list_categories( $args ); } } }`

カテゴリに投稿がない場合でもリストを表示するには、 `$ args=array( 'hide_empty'=>false、);` `$terms=get_terms($taxonomy、$ args)`である必要があります.

Should be `$args = array( 'hide_empty' => false, );` `$terms = get_terms($taxonomy, $args)` to see list even when categories do not have posts.
