这与问题不同：How to display categories of my Custom Post Type?

我有一个自定义的帖子类型-播客。我添加了分类法“category”，因为我希望我的“podcast”与我的帖子共享“category”分类法。我有一个归档页面（archive podcasts.php），它在url/podcasts/处显示播客，但它shows all the categories. 我想在中显示我的播客a single category at a time, 比如在mysite。com/podcasts/category/mycategory/

或者更好：mysite。com/category/mycategory/podcasts/

理想情况下，它将使用我现有的存档播客。php模板。

以下是我的自定义帖子类型创建：

function podcast_post_type() {

// Set UI labels for Podcast post Type
    $labels = array(
       //redacted my labels because they aren\'t important here.
    );

// Set other options for Podcast post Type

    $args = array(
        \'label\'               => __( \'podcasts\', \'understrap\' ),
        \'description\'         => __( \'Podcasts\', \'understrap\' ),
        \'labels\'              => $labels,
        // Features this CPT supports in Post Editor
        \'supports\'            => array( \'title\', \'editor\', \'excerpt\', \'author\', \'thumbnail\', \'comments\', \'revisions\', \'custom-fields\', ),
        // You can associate this CPT with a taxonomy or custom taxonomy. 
        \'taxonomies\'          => array(  \'category\' ),
        /* A hierarchical CPT is like Pages and can have
        * Parent and child items. A non-hierarchical CPT
        * is like Posts.
        */  
        \'hierarchical\'        => false,
        \'public\'              => true,
        \'show_ui\'             => true,
        \'show_in_menu\'        => true,
        \'show_in_nav_menus\'   => true,
        \'show_in_admin_bar\'   => true,
        \'menu_position\'       => 5,
        \'can_export\'          => true,
        \'has_archive\'         => true,
        \'exclude_from_search\' => false,
        \'publicly_queryable\'  => true,
        \'capability_type\'     => \'post\',
    );

    // Registering your Podcast post Type
    register_post_type( \'podcasts\', $args );

}

以下代码似乎很有希望，但不起作用：

add_action(\'init\', \'category_cpt_rewrites\');

function category_cpt_rewrites() {
    $custom_post_types = array(\'podcasts\'); //some example post types
    foreach ( $custom_post_types as $post_type ) {
        $rule = \'^\' . $post_type . \'/category/(.+?)/?$\';
        $rewrite = \'index.php?post_type=\' . $post_type . \'&category_name=$matches[1]\';
        add_rewrite_rule($rule,$rewrite,\'top\');
    }
}

实际上，我有点期待这会自动工作——通过在我的帖子类型中添加“类别”分类法，我认为Wordpress会有一个url，我可以在那里访问我的播客类别。

我为此浪费了很多时间，看起来应该很简单——感谢您的帮助！

function custom_category_rewrite() {

    /**
     * Here you build an array containing the post type keys that you want
     * the rule to work for.
     */
    $custom_post_types = array(\'podcast\');

    foreach ( $custom_post_types as $post_type ) {
        /**
         * Adds rewrite rule which will rewrite sth like http://yoursite.com/podcast/category/category-name/ to
         * http://yoursite.com/index.php?post_type=podcast&category_name=category-name
         */
        add_rewrite_rule( "^$post_type/category/(.+)/?$", \'index.php?post_type=\' . $post_type . \'&category_name=$matches[1]\', \'top\' );
    }

    flush_rewrite_rules();

}

add_action( \'init\', \'custom_category_rewrite\' );
