根据 WordPress 中的多个用户角色显示内容 [英] Show content based on multiple user roles in WordPress

问题描述

我希望显示基于多个不同用户角色的内容.

I am looking to display content based on multiple different user roles.

目的是为两个或三个不同的用户角色显示内容，然后为其他用户角色阻止它，显示一条消息，它只适用于某些登录用户.

The aim is to display content for two or three different user roles, and then block it for other user roles, displaying a message that it is only for certain logged in users.

到目前为止，我有以下几点:

So far, I have the following:

<?php 
    global $user_login, $current_user;
    get_currentuserinfo();
    $user_info = get_userdata($current_user->ID);
    $roles = array (
        'administrator',
        'subscriber',
    );

if (is_user_logged_in() && in_array( $roles, $user_info->roles)) {

//content here

} else {

// they aren't logged in, so show them the login form

}
?>

目前，我遇到的问题似乎是代码同时寻找管理员和订阅者角色，因此不满足 if 语句并显示登录表单.

At the moment, the issue I am having seems to be that the code is looking for both the administrator and subscriber roles at the same time and as a result, the if statement is not satisfied and the login form shows.

如果我将 $roles 更改为管理员"或订阅者"，它就可以正常工作.

If I change $roles to 'administrator' or 'subscriber', it then works fine.

那么，我将如何搜索数组以显示任一角色，而不是所有角色.

So, how would I search through the array to display either role, not all of them.

谢谢

推荐答案

您可以使用:array_intersect(链接)

You could use: array_intersect (link)

array_intersect 将检查两个数组之间的针($roles)是否存在于大海捞针($user_info->roles)中.我已经在我自己的身上进行了测试，效果很好.

array_intersect will check between two array to see if the needle ($roles) exists in the haystack ($user_info->roles). I have tested this against my own and works well.

见下文array_intersect的使用.

<?php 
    global $user_login, $current_user;
    get_currentuserinfo();
    $user_info = get_userdata($current_user->ID);
    $roles = array (
        'administrator',
        'subscriber',
    );

if (is_user_logged_in() && array_intersect( $roles, $user_info->roles)) {

echo 'success';

} else {

echo 'failure';

}
?>

示例 1:LINK $roles 数组不匹配.

示例 2:LINK $roles 数组有一场比赛.
