我有一个Joomla插件，它在Joomla和WordPress之间进行单向单点登录 .
这意味着注册和登录由Joomla处理，每当有人在Joomla中注册时，它会将用户的数据复制到WordPress用户表中，每当有人登录到Joomla时，它会将用户的状态写入登录到WordPress cookie中，从而用户自动记录进入WordPress .
然而，WordPress并非如此 . 如果有人登录到WordPress或注册到WordPress，它将不会执行这些操作 .
因此，我想将用户从Wordpress转移到Joomla页面进行登录和注册活动 .
例：
Joomla login page: http://www.xyz.com/index.php?option=com_user&view=login&Itemid=204
Joomla registration page: http://www.xyz.com/index.php?option=com_user&view=login&Itemid=205
现在我希望当用户点击默认Meta Widget中的登录链接时，它必须将用户带到上面的Joomla页面，同样当用户点击Register时，它必须将用户带到上面的注册页面 .
我正在寻找一个解决方案，最好不要破解核心文件 . Please feel free to suggest if there is a better solution then what I am looking for above .
我使用Atom theme并且它有一个内置的登录表单小部件，该小部件的代码是：
Please note: 我是编程的新手，因此请求详细的回复 .
