我有一个名为“News”的自定义帖子类型，如下所示：

/**
 * Register "News" custom post type
 */
function news_custom_post_type() {

    $labels = array(
        \'name\'                  => _x( \'News\', \'Post Type General Name\', \'school\' ),
        \'singular_name\'         => _x( \'News Item\', \'Post Type Singular Name\', \'school\' ),
        \'menu_name\'             => __( \'News\', \'school\' ),
        \'name_admin_bar\'        => __( \'News\', \'school\' ),

        \'view_items\'            => __( \'View Posts\', \'school\' ),
        \'search_items\'          => __( \'Search Posts\', \'school\' ),
        \'not_found\'             => __( \'Not found\', \'school\' ),
        \'not_found_in_trash\'    => __( \'Not found in Trash\', \'school\' ),

        \'uploaded_to_this_item\' => __( \'Uploaded to this post\', \'school\' ),
        \'items_list\'            => __( \'Posts list\', \'school\' ),
        \'items_list_navigation\' => __( \'Posts list navigation\', \'school\' ),
        \'filter_items_list\'     => __( \'Filter posts list\', \'school\' ),
    );
    $args = array(
        \'label\'                 => __( \'News Post\', \'school\' ),
        \'description\'           => __( \'A custom post type for news posts.\', \'school\' ),
        \'labels\'                => $labels,
        \'supports\'              => array( \'title\', \'editor\', \'excerpt\' ),
        \'taxonomies\'            => array( \'news\' ),
        \'hierarchical\'          => false,
        \'public\'                => true,
        \'show_ui\'               => true,
        \'show_in_menu\'          => true,
        \'menu_position\'         => 5,

    );
    register_post_type( \'news\', $args );

}
add_action( \'init\', \'news_custom_post_type\', 0 );

我还为此帖子类型设置了分类：

/**
 * Register "News" Categories
 */
function news_categories() {

    $labels = array(
        \'name\'                       => _x( \'Categories\', \'Taxonomy General Name\', \'school\' ),
        \'singular_name\'              => _x( \'Category\', \'Taxonomy Singular Name\', \'school\' ),
        \'menu_name\'                  => __( \'Categories\', \'school\' ),
        \'all_items\'                  => __( \'All Items\', \'school\' ),
        \'parent_item\'                => __( \'Parent Category\', \'school\' ),
        \'parent_item_colon\'          => __( \'Parent Category:\', \'school\' ),
        \'new_item_name\'              => __( \'New Category Name\', \'school\' ),
        \'add_new_item\'               => __( \'Add New Category\', \'school\' ),
        \'edit_item\'                  => __( \'Edit Category\', \'school\' ),
        \'update_item\'                => __( \'Update Category\', \'school\' ),
        \'view_item\'                  => __( \'View Category\', \'school\' ),

        \'popular_items\'              => __( \'Popular Categories\', \'school\' ),
        \'search_items\'               => __( \'Search Categories\', \'school\' ),
        \'not_found\'                  => __( \'Not Found\', \'school\' ),
        \'no_terms\'                   => __( \'No items\', \'school\' ),
        \'items_list\'                 => __( \'Categories list\', \'school\' ),
        \'items_list_navigation\'      => __( \'Categories list navigation\', \'school\' ),
    );
    $args = array(
        \'labels\'                     => $labels,
        \'hierarchical\'               => true,
        \'public\'                     => true,
        \'show_ui\'                    => true,
        \'show_admin_column\'          => true,
        \'show_in_nav_menus\'          => true,
        \'show_tagcloud\'              => true,
    );
    register_taxonomy( \'news\', array( \'news\' ), $args );

}
add_action( \'init\', \'news_categories\', 0 );

我已经通过WP Admin添加了我的类别，并创建了三篇带有这些类别的帖子。

通过小部件，我添加了“类别”小部件。当您访问新闻存档页面时，小部件会显示“无类别”。

有什么想法吗？
