这应该与“页面”非常相似。

function gallery_type_custom_init() {
    $args = array( 
        \'public\' => true, 
        \'label\' => \'Gallery\',
        \'capability_type\' => \'page\',
        \'hierarchical\' => true,
        \'supports\' => array( 
               \'title\', 
               \'editor\', 
               \'thumbnail\', 
               \'excerpt\', 
               \'page-attributes\', 
               \'custom-fields\' 
      )
    );
    register_post_type( \'Gallery\', $args );
}
add_action( \'init\', \'gallery_type_custom_init\' );
