将WordPress登录名转移并注册到Joomla的链接 [英] Diverting WordPress login and register links to Joomla
本文介绍了将WordPress登录名转移并注册到Joomla的链接的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个Joomla插件，可以在Joomla和WordPress之间进行单向单点登录.
I have a Joomla plugin which does a one-way single sign-on between Joomla and WordPress.
这意味着注册和登录由Joomla处理，每当有人在Joomla中进行注册时，它将用户的数据复制到WordPress用户表中，并且每当有人登录Joomla时，它将用户的状态记录为登录到WordPress cookie中，从而使用户自动登录到WordPress.
It means the registrations and logins are handled by Joomla and every time someone registers in Joomla it replicates the user's data into WordPress user tables and everytime someone logs into Joomla it writes the user's status as logged in into the WordPress cookie thus the user automatically gets logged into WordPress.
但是WordPress并非如此.如果有人登录WordPress或注册WordPress，它将不会执行这些操作.
However this is not the case with WordPress. It will not do these actions if someone logs into WordPress or registers into WordPress.
因此，我想将用户从Wordpress转移到Joomla页面进行登录和注册活动.
Hence I want to divert users from Wordpress to Joomla pages for login and registration activities.
示例:
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，我希望当用户单击默认Meta Widget中的登录链接时，必须将用户带到上面的Joomla页面，并且类似地，当用户单击注册"时，必须将用户带到上面的注册页面.
Now I want that when a user clicks on the login link in the default Meta Widget it must take the user to the above Joomla page and similarly when the user clicks on Register, it must take the user to the above registration page.
我正在寻找一种解决方案，最好不要破坏核心文件. 请随时建议是否有比我上面想要的解决方案更好的解决方案.
I am looking for a solution preferably without hacking the core files. Please feel free to suggest if there is a better solution then what I am looking for above.
我使用 Atom主题，它具有内置的登录表单小部件，并且该小部件的代码为:
I use the Atom theme and it has a built-in login form widget, and the code for that widget is:
请注意::我是编程新手，因此需要详细答复.

推荐答案
替换此
<form id="<?php echo $this->id; ?>_login" action="<?php echo site_url('wp-login.php', 'login_post') ?>" method="post">
使用
<form id="<?php echo $this->id; ?>_login" action="<?php echo 'http://www.xyz.com/index.php?option=com_user&view=login&Itemid=204' ?>" method="post">
用于登录和注册链接替换
for logging in and for registering link replace
$register_link = site_url('wp-login.php?action=register', 'login');
使用
$register_link = 'http://www.xyz.com/index.php?option=com_user&view=login&Itemid=205';
P.S-我自己没有尝试过
