是的，WP中有一个功能：wp_check_post_lock()

给它一个帖子ID，它将返回当前正在编辑帖子的用户ID，如果没有人编辑帖子，它将返回false（即未锁定）。

$is_locked = wp_check_post_lock( $post_id );

if ( false === $is_locked ) {

     // Post $post_id is not not locked for editing

} else {

     // Post is not locked, $is_locked contains the user ID who is editing.
     $user = get_user_by( \'id\', $is_locked );
     echo \'Post id being edited by \' . $user->user_login;

}
