我有一个自定义的帖子类型，在我的函数中设置了以下内容。php。问题是，即使在我指定了\'supports\' => array(\'title\',\'editor\',\'thumbnail\'),. 我有什么遗漏吗？

add_theme_support( \'post-thumbnails\', array( \'post\' ) );

// Register Talents
add_action(\'init\', \'register_talents\');

function register_talents() {

    $labels = array(
        \'name\' => _x(\'Talents\', \'post type general name\'),
        \'singular_name\' => _x(\'Talent\', \'post type singular name\'),
        \'add_new\' => _x(\'Add New\', \'talent item\'),
        \'add_new_item\' => __(\'Add New Talent\'),
        \'edit_item\' => __(\'Edit Talent\'),
        \'new_item\' => __(\'New Talent\'),
        \'view_item\' => __(\'View Talent\'),
        \'search_items\' => __(\'Search Talents\'),
        \'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\' => null,
        \'menu_icon\' => get_stylesheet_directory_uri() . \'/images/menu-talents.png\',
        \'supports\' => array(\'title\',\'editor\',\'thumbnail\'),
        \'has_archive\' => true
      );

    register_post_type( \'talents\' , $args );
}
