对于开放注册的 WordPress 站点来说，尤其是有会员购买服务的站点，可能需要禁止用户共享账号，也就是要禁止多个人同时登录一个账号。倡萌今天分享老外的一个方法，大家不妨试试。将下面的代码到主题的 functions.php 中即可：/*** Detect if the current user has concurrent sessions** @return bool*/function pcl_user_has_concurrent_sessions() {return ( is_user_logged_in() && count( wp_get_all_sessions() ) > 1 );}/*** Get the user's current session array** @return array*/function pcl_get_current_session() {$sessions = WP_Session_Tokens::get_instance( get_current_user_id() );return $sessions->get( wp_get_session_token() );}/*** Only allow one session per user** If the current user's session has been taken over by a newer* session then we will destroy their session automattically and* they will have to login again to continue.** @action init** @return void*/function pcl_disallow_account_sharing() {if ( ! pcl_user_has_concurrent_sessions() ) {return;}$newest = max( wp_list_pluck( wp_get_all_sessions(), 'login' ) );$session = pcl_get_current_session();if ( $session['login'] === $newest ) {wp_destroy_other_sessions();} else {wp_destroy_current_session();}}add_action( 'init', 'pcl_disallow_account_sharing' );如果大家不想折腾代码，可以直接下载插件 Prevent Concurrent Logins 安装启用也是一样的。 |
