在PHP Foreach Loop之外使用变量 [英] Using a variable outside PHP Foreach Loop

问题描述

我正在尝试在foreach循环之外输出用户名和用户电子邮件。我正在尝试向所有WordPress用户发送一封电子邮件到一定的用户角色。

I am trying to output a username and user email outside of a foreach loop. I am trying to send an email to all WordPress users that are within a certain User Role.

这是我的代码：

// Get users and their roles
    $user_args = array(
      'role__in' => 'new_role', 
      'orderby'  => 'user_nicename',
      'order'    => 'ASC'
    );  
    $users = get_users($user_args); 

    foreach ( $users as $user ) :       
        $user_name  = $user->user_email;
        $user_email = $user->display_name;          
    endforeach;

所以我可以在页面的其他区域使用它们，即：。

So I can then use them in other areas of the page, ie:.

echo 'Hello, ' . $user_name;
echo 'Send to: ' .$user_email;

我已打印出包含以下内容的$ users数组：

I've printed out the $users array which contains the following:

推荐答案

如果您想向所有具有特定角色的用户发送电子邮件，请尝试以下操作：

If you want to send an email to all users with a certain role, try something like this:

// Get users and their roles
$user_args = array(
  'role__in' => 'new_role', 
  'orderby'  => 'user_nicename',
  'order'    => 'ASC'
);

$users = get_users($user_args); 

foreach ( $users as $user ) :       
    $user_email  = $user->user_email;
    $user_name = $user->display_name;
    send_email($user_name, $user_email);          
endforeach;

然后编写您的电子邮件功能：

And then write your email function:

function send_email($name, $email) {
    // Do email sending stuff here with $name & $email
}
