字preSS生成用户登录WP_Error对象？ [英] Wordpress to generate WP_Error Object for user login?

问题描述

我想即使正确返回登录错误信息用户键入他们的特权。换言之，以终止登录并显示错误信息。

I want to return the Login Error Message even user key-in their privileges correctly. In other words, to terminate the login and show the error message.

当我们键入错误的密码，文字preSS所示：

When we key-in wrong passwords, wordpress shows:

There was an error authenticating your details.

ERROR: The password you entered for the username admin is incorrect. Lost your password?

..在登录页面上。这是因为 WP_Error 返回的对象。

.. on the login page. This is because of WP_Error Object is returned.

所以，我好奇的问题是：

So my curious question is:

• 如何获得/生成我自己的这个 WP_Error 对象，即可返回？它是阵列？

• How to get/generate this WP_Error Object on my own, to return back? Is it Array?

推荐答案

您需要连接到身份验证字preSS挂钩。然后返回一个新的WP_Error对象生成错误消息并重定向回登录页面。下面是一个例子。

You need to hook into the authenticate wordpress hook. Then return a new WP_Error object to generate an error message and redirect back to the login page. Here is an example.

add_filter('authenticate', 'check_login_submit', 40, 3);

function check_login_submit($user, $username, $password) {
    $WP_Error = new WP_Error();
    $WP_Error->add('my_error', '<strong>Error</strong>: Something went wrong.');
    return $WP_Error;
}
