混淆自定义帖子类型类别和分类

我创建了三个自定义帖子类型，其中一个名为"TV" . 我还在WP仪表板中创建了一个类别，它出现在所有这三个自定义帖子类型以及"Posts"中 . 我从这些自定义帖子类型和帖子中分配了几个帖子到该类别 . 但是，当我尝试在"the_query"循环和 Category Posts Widget 插件中显示类别时，该类别未显示自定义帖子类型中的帖子 . 它只显示来自"Posts"的帖子 .

我在网上看了https://codex.wordpress.org/Function_Reference/register_post_type中的Wordpress Codex说"When registering a post type, always register your taxonomies using the taxonomies argument" .

当我在下面的代码中添加 taxonomies' => array( 'category', 'post_tag' ) 时，我已经在 register_post_type() 中调用了't really get it. I thought that Taxonomy is same as Category, right? And that it'：

// Register Custom Post Type
function tvs_post_type() {

    $labels = array(
        'name'                  => _x( 'TV', 'Post Type General Name', 'text_domain' ),
        'singular_name'         => _x( 'TV', 'Post Type Singular Name', 'text_domain' ),
        'menu_name'             => __( 'TV', 'text_domain' ),
        'name_admin_bar'        => __( 'Post Type', 'text_domain' ),
        'archives'              => __( 'Item Archives', 'text_domain' ),
        'parent_item_colon'     => __( 'Parent TV:', 'text_domain' ),
        'all_items'             => __( 'All TVs', 'text_domain' ),
        'add_new_item'          => __( 'Add New Post', 'text_domain' ),
        'add_new'               => __( 'Add New Post', 'text_domain' ),
        'new_item'              => __( 'New Item', 'text_domain' ),

        'search_items'          => __( 'Search Posts', 'text_domain' ),
        'not_found'             => __( 'No posts found', 'text_domain' ),
        'not_found_in_trash'    => __( 'Not posts found in Trash', 'text_domain' ),
        'featured_image'        => __( 'Featured Image', 'text_domain' ),
        'set_featured_image'    => __( 'Set featured image', 'text_domain' ),
        'remove_featured_image' => __( 'Remove featured image', 'text_domain' ),
        'use_featured_image'    => __( 'Use as featured image', 'text_domain' ),
        'insert_into_item'      => __( 'Insert into item', 'text_domain' ),
        'uploaded_to_this_item' => __( 'Uploaded to this item', 'text_domain' ),
        'items_list'            => __( 'Items list', 'text_domain' ),
        'items_list_navigation' => __( 'Items list navigation', 'text_domain' ),
        'filter_items_list'     => __( 'Filter items list', 'text_domain' ),
    );
    $args = array(
        'label'                 => __( 'TV', 'text_domain' ),
        'description'           => __( 'tv information pages', 'text_domain' ),
        'labels'                => $labels,
        'supports'              => array( 'title', 'editor', 'excerpt', 'author', 'thumbnail', 'comments', 'custom-fields', ),
        'taxonomies'            => array( 'category', 'post_tag' ),
        'hierarchical'          => false,
        'public'                => true,
        'show_ui'               => true,
        'show_in_menu'          => true,
        'menu_position'         => 5,
        'show_in_admin_bar'     => true,
        'show_in_nav_menus'     => true,
        'can_export'            => true,
        'has_archive'           => true,        
        'exclude_from_search'   => false,
        'publicly_queryable'    => true,
        'capability_type'       => 'page',
    );
    register_post_type( 'tv', $args );

}
add_action( 'init', 'tvs_post_type', 0 );

救命？如此迷茫....

    没关系 . 我想出了大部分内容 . 调用自定义帖子类型的类别需要将 post_type 添加到查询中，如下所示

    <?php 
    $args = array (
        'cat'              => 3,
        'post_type'        => array( 'post', 'tv', 'print', 'radio' ), //defined the post type. The default is post.
        'posts_per_page'   => 3
    );

     $the_query = new WP_Query( $args ); ?>
            <?php if ( $the_query->have_posts() ) : ?>

        <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?> 
           <?php the_title(); ?>
        <?php endwhile;  ?>

    <?php endif;
     wp_reset_postdata();
    ?>

    至于 Category Posts Widget 插件，看起来它只显示查询中带有 post_type => post 的帖子，我想？所以我使用 Ultimate Posts Widget 插件，它的工作原理 .
