因此，我有下面的代码试图创建媒体库自定义帖子类型，但我没有得到媒体库，它只是一个常规的帖子类型。

下面是我的类中的方法：

public static function doc_post_type() {
    add_action(\'init\', function() {
        $labels = array(
            \'name\' => _x(\'Doc\', \'post type general name\'),
            \'singular_name\' => _x(\'Doc\', \'post type singular name\'),
            \'menu_name\' => \'Docs\',
            \'add_new\' => _x(\'Add New\', \'doc item\'),
            \'parent_item_colon\' => \'\'
        );

        register_post_type(\'doc_post_type\' , array(
            \'labels\' => $labels,
            \'public\' => true,
            \'has_archive\' => false,
            \'rewrite\' => false,
            \'supports\' => array(\'title\', \'editor\')
        ));
    });
    register_taxonomy_for_object_type(\'media_category\', \'doc_post_type\');
}
