カテゴリエディタにカスタムフィールドを追加する例はありますか？

私はこのナッツを割るのにかなり近いと思います:)

カテゴリエディタにカスタムフィールドのセットを追加しようとしています.ポストメタを扱っていないので、カスタムカテゴリフィールドの値をwp_optionsテーブルではなくwp_term_taxonomyテーブルに書き込むと思います.これは正しいですか?

これを行う方法の例がある場合は、リンクまたはコードを共有してください.カスタムカテゴリフィールドをキャプチャして保存する方法がわかりません.

これが私のコードです...

 //add the hook to place the form on the category editor screen
add_action('edit_category_form','ce4_category_admin');

//Adds the custom title box to the category editor
function ce4_category_admin($category){
    echo "category: ".$category->term_id; //great, I got a reference to the term_id, now I need to get/set my custom fields with this key
    ?>
<table class="form-table">
        <tr class="form-field">
            <th scope="row" valign="top"><label for="_ce4-categoryTitle">Full Category Title</label></th>
            <td><input name="_ce4-categoryTitle" id="_ce4-categoryTitle" type="text" size="40" aria-required="false" value="<?php echo get_taxonomy($category->term_id, '_ce4-categoryTitle'); ?>" />
            <p class="description">The title is optional but will be used in place of the name on the home page category index.</p></td>
        </tr>
        <tr class="form-field">
            <th scope="row" valign="top"><label for="_ce4_fullDescription">Full Category Text for Landing Page</label></th>
            <td><textarea style="height:70px; width:100%;margin-left:-5px;" name="_ce4_fullDescription" id="_ce4_fullDescription"><?php echo get_taxonomy($category->term_id, '_ce4_fullDescription'); ?></textarea>
            <p class="description">This text will appear on the category landing page when viewing all articles in a category. The image, you supply above, if any, will be used here and this content will wrap around it.</p></td>
        </tr>
</table>
<?php
}

//How to save the custom field data? Normally I'd use..
//add_action('save_post', 'custom_save_function');
//but this is not a post, so perhaps there's another method?

I think I'm pretty close to cracking this nut :)

I'm trying to add a set of custom fields to the Category editor. Since I'm not dealing with post meta, I believe I'll be writing my custom category field values to the wp_term_taxonomy table rather than the wp_options table. Is this correct?

If there are any examples of how to do this, please share a link or bit of code. I'm not sure how to capture and save my custom category fields.

Here's my code...

//add the hook to place the form on the category editor screen
add_action('edit_category_form','ce4_category_admin');

//Adds the custom title box to the category editor
function ce4_category_admin($category){
    echo "category: ".$category->term_id; //great, I got a reference to the term_id, now I need to get/set my custom fields with this key
    ?>
<table class="form-table">
        <tr class="form-field">
            <th scope="row" valign="top"><label for="_ce4-categoryTitle">Full Category Title</label></th>
            <td><input name="_ce4-categoryTitle" id="_ce4-categoryTitle" type="text" size="40" aria-required="false" value="<?php echo get_taxonomy($category->term_id, '_ce4-categoryTitle'); ?>" />
            <p class="description">The title is optional but will be used in place of the name on the home page category index.</p></td>
        </tr>
        <tr class="form-field">
            <th scope="row" valign="top"><label for="_ce4_fullDescription">Full Category Text for Landing Page</label></th>
            <td><textarea style="height:70px; width:100%;margin-left:-5px;" name="_ce4_fullDescription" id="_ce4_fullDescription"><?php echo get_taxonomy($category->term_id, '_ce4_fullDescription'); ?></textarea>
            <p class="description">This text will appear on the category landing page when viewing all articles in a category. The image, you supply above, if any, will be used here and this content will wrap around it.</p></td>
        </tr>
</table>
<?php
}

//How to save the custom field data? Normally I'd use..
//add_action('save_post', 'custom_save_function');
//but this is not a post, so perhaps there's another method?

いいえ. wp_term_taxonomyテーブルに新しいフィールドを作成できないため、wp_optionsを使用する必要があります(作成すると、次のWPアップデートでそれらが失われます).

だから:

 // the option name
define('MY_CATEGORY_FIELDS', 'my_category_fields_option');

// your fields (the form)
add_filter('edit_category_form', 'my_category_fields');
function my_category_fields($tag) {
    $tag_extra_fields = get_option(MY_CATEGORY_FIELDS);

    ?>

<table class="form-table">
        <tr class="form-field">
            <th scope="row" valign="top"><label for="_ce4-categoryTitle">Full Category Title</label></th>
            <td><input name="_ce4-categoryTitle" id="_ce4-categoryTitle" type="text" size="40" aria-required="false" value="<?php echo $tag_extra_fields[$tag->term_id]['my_title']; ?>" />
            <p class="description">The title is optional but will be used in place of the name on the home page category index.</p></td>
        </tr>
        <tr class="form-field">
            <th scope="row" valign="top"><label for="_ce4_fullDescription">Full Category Text for Landing Page</label></th>
            <td><textarea style="height:70px; width:100%;margin-left:-5px;" name="_ce4_fullDescription" id="_ce4_fullDescription"><?php  echo $tag_extra_fields[$tag->term_id]['my_description']; ?></textarea>
            <p class="description">This text will appear on the category landing page when viewing all articles in a category. The image, you supply above, if any, will be used here and this content will wrap around it.</p></td>
        </tr>
</table>

    <?php
}


// when the form gets submitted, and the category gets updated (in your case the option will get updated with the values of your custom fields above
add_filter('edited_terms', 'update_my_category_fields');
function update_my_category_fields($term_id) {
  if($_POST['taxonomy'] == 'category'):
    $tag_extra_fields = get_option(MY_CATEGORY_FIELDS);
    $tag_extra_fields[$term_id]['my_title'] = strip_tags($_POST['_ce4-categoryTitle']);
    $tag_extra_fields[$term_id]['my_description'] = strip_tags($_POST['_ce4_fullDescription']);
    update_option(MY_CATEGORY_FIELDS, $tag_extra_fields);
  endif;
}


// when a category is removed
add_filter('deleted_term_taxonomy', 'remove_my_category_fields');
function remove_my_category_fields($term_id) {
  if($_POST['taxonomy'] == 'category'):
    $tag_extra_fields = get_option(MY_CATEGORY_FIELDS);
    unset($tag_extra_fields[$term_id]);
    update_option(MY_CATEGORY_FIELDS, $tag_extra_fields);
  endif;
}

最後の2つにはカテゴリ関連のフックがあるかもしれませんが、私はそれらを検索しませんでした.管理者がカスタム分類用語に画像を添付できる私の古いテーマから上記のコードを適応させました...

No. You have to use wp_options, because you can't create new fields in the wp_term_taxonomy table (If you do, in the next WP update you'll loose them).

So:

// the option name
define('MY_CATEGORY_FIELDS', 'my_category_fields_option');

// your fields (the form)
add_filter('edit_category_form', 'my_category_fields');
function my_category_fields($tag) {
    $tag_extra_fields = get_option(MY_CATEGORY_FIELDS);

    ?>

<table class="form-table">
        <tr class="form-field">
            <th scope="row" valign="top"><label for="_ce4-categoryTitle">Full Category Title</label></th>
            <td><input name="_ce4-categoryTitle" id="_ce4-categoryTitle" type="text" size="40" aria-required="false" value="<?php echo $tag_extra_fields[$tag->term_id]['my_title']; ?>" />
            <p class="description">The title is optional but will be used in place of the name on the home page category index.</p></td>
        </tr>
        <tr class="form-field">
            <th scope="row" valign="top"><label for="_ce4_fullDescription">Full Category Text for Landing Page</label></th>
            <td><textarea style="height:70px; width:100%;margin-left:-5px;" name="_ce4_fullDescription" id="_ce4_fullDescription"><?php  echo $tag_extra_fields[$tag->term_id]['my_description']; ?></textarea>
            <p class="description">This text will appear on the category landing page when viewing all articles in a category. The image, you supply above, if any, will be used here and this content will wrap around it.</p></td>
        </tr>
</table>

    <?php
}


// when the form gets submitted, and the category gets updated (in your case the option will get updated with the values of your custom fields above
add_filter('edited_terms', 'update_my_category_fields');
function update_my_category_fields($term_id) {
  if($_POST['taxonomy'] == 'category'):
    $tag_extra_fields = get_option(MY_CATEGORY_FIELDS);
    $tag_extra_fields[$term_id]['my_title'] = strip_tags($_POST['_ce4-categoryTitle']);
    $tag_extra_fields[$term_id]['my_description'] = strip_tags($_POST['_ce4_fullDescription']);
    update_option(MY_CATEGORY_FIELDS, $tag_extra_fields);
  endif;
}


// when a category is removed
add_filter('deleted_term_taxonomy', 'remove_my_category_fields');
function remove_my_category_fields($term_id) {
  if($_POST['taxonomy'] == 'category'):
    $tag_extra_fields = get_option(MY_CATEGORY_FIELDS);
    unset($tag_extra_fields[$term_id]);
    update_option(MY_CATEGORY_FIELDS, $tag_extra_fields);
  endif;
}

There might be some category-related hooks for the last two, I didn't search for them. I just adapted the code above from a old theme of mine in which the admin can attach a image to a custom taxonomy term...

@AA:ありがとう、これはうまくいきます！カテゴリアーカイブページを表示しているときに、タイトルの値をどのように取得しますか?

@AA: Thanks, this works great! How would you retrieve the value for the title when you are viewing the category archive page?

私はこのコードを使用しましたが、うまく機能します.追加したいフィールドが[カテゴリの追加]ボタンの下に配置されていることがわかりました.ボタンの上に新しいフィールドを表示する方法を知っていますか?コードからテーブルを削除して、trとtdを残してみましたが、機能しませんでした

I used this code and it works great. I found that the field I want to add gets put below the add category button. Do you know a way to get the new fields to show above the button? I tried removing the table from the code and just left the tr and td but that didn't work

はい、どうやらWPには、使用できる新しいアクションがあります.`edit_category_form`の代わりに主に`edit_category_form_fields`.[edit_tags.php](http://core.svn.wordpress.org/trunk/wp-admin/edit-tags.php)を参照してください

yes, apparently WP has new actions now which you can use. Mainly `edit_category_form_fields` instead of `edit_category_form`. See [edit_tags.php](http://core.svn.wordpress.org/trunk/wp-admin/edit-tags.php)

add_action(. "_ add_form_fields"、my_action)を使用して、カテゴリフォームエディタを拡張します.つまり、分類タイプ「store」のカスタムアクションフックのオブジェクトコンテキスト内のadd_action( "store_add_form_fields"、array($this、 'add_form_fields)).WordPressのバージョン3.X +は、アクションフックに形式を優先し、古いスタイルの「edit_category_form_fields」などはコードで「レガシーサポート」としてマークされます.つまり、最終的にはなくなる可能性があります..参照:http://core.trac.wordpress.org/browser/tags/3.4.2/wp-admin/edit-tags.php

Use add_action(."_add_form_fields",my_action) to extend the category form editor. i.e. add_action("store_add_form_fields",array($this,'add_form_fields)) in an object context for your custom action hooks for a taxonomy type of 'store'. Version 3.X+ of WordPress prefers the format for action hooks, the older style of "edit_category_form_fields" and others are marked as "legacy support" in the code, which means they may/will eventually go away. ref: http://core.trac.wordpress.org/browser/tags/3.4.2/wp-admin/edit-tags.php
