添加小示例函数：
add_action( \'request\', \'fb_add_to_feed\' );
// add to post-feed
function fb_add_to_feed($request) {
if ( isset($request[\'feed\']) && !isset($request[\'post_type\']) ) {
$request[\'post_type\'] = get_post_types( $args = array(
\'public\' => true,
\'capability_type\' => \'post\'
) );
}
return $request;
}
或者，您可以仅为自定义帖子类型创建自己的提要。有关草稿帖子的“草稿提要”，请参见以下示例。
