get_current_user_id()不能与wp_login挂钩一起使用-WordPress [英] get_current_user_id() Not Working with wp_login Hook - WordPress

问题描述

我编写了一个函数，该函数对大多数钩子(例如wp_head)都适用.问题是，我似乎无法获得用户的用户ID，因为他们使用wp_login作为我的钩子登录.

I wrote a function and it works great with most hooks, such as wp_head. The problem is, I can't seem to get the user ID for a user, as they log in with wp_login as my hook.

get_current_user_id()不返回任何内容，而且我似乎也无法获取任何其他用户对象.实际登录是否在wp_login之后进行?因为那对我来说没有意义.

get_current_user_id() returns nothing, and I can't seem to get any other user object either. Does the actual login happen AFTER wp_login? Because that doesn't make sense to me.

推荐答案

我没有让get_current_user_id()工作，但确实找到了解决方案.

I never got get_current_user_id() to work, but I did find a solution.

首先，我不得不给我的功能一个非常低的优先级.在动作挂钩中，我将其设置为99优先级，如下所示:

First, I had to give my function very low priority. In the action hook, I gave it 99 priority, like so:

add_action( 'wp_login', 'my_function', 99 );

然后，我没有使用get_current_user_id()，而是向函数添加了$login参数，并使用了get_userdatabylogin($login)，这为我提供了用户信息.然后就是$user_ID = $user->ID.因此，获取ID包括以下内容:

Then, instead of using get_current_user_id(), I added a $login parameter to the function and used get_userdatabylogin($login), which gave me the user information. Then it was just $user_ID = $user->ID. So getting the ID consisted of this:

function my_function( $login ) {
    $user = get_user_by('login',$login);
    $user_ID = $user->ID;
    //do something with the User ID
}
