如何通过此代码检索WordPress中具有特定角色的用户的电子邮件地址

借助以下代码，我能够检索WordPress中所有用户的电子邮件地址：

<?php
$users = get_users();
foreach ($users as $user ) { 
$email = get_user_meta($user->ID, "email", true);
?>

<?php
$users = get_users();
foreach ($users as $user ) { 
    if ( in_array( 'subscriber', (array) $user->roles ) ) {
        $email = get_user_meta($user->ID, "email", true);
    }
}
?>

我想通过修改上述代码来检索仅具有订户角色（slug=Subscriber）的用户的电子邮件地址

请给出建议。

您可以尝试以下代码：

<?php
$users = get_users();
foreach ($users as $user ) { 
$email = get_user_meta($user->ID, "email", true);
?>

<?php
$users = get_users();
foreach ($users as $user ) { 
    if ( in_array( 'subscriber', (array) $user->roles ) ) {
        $email = get_user_meta($user->ID, "email", true);
    }
}
?>

您可以尝试以下代码：

<?php
$users = get_users();
foreach ($users as $user ) { 
$email = get_user_meta($user->ID, "email", true);
?>

<?php
$users = get_users();
foreach ($users as $user ) { 
    if ( in_array( 'subscriber', (array) $user->roles ) ) {
        $email = get_user_meta($user->ID, "email", true);
    }
}
?>

允许您按特定角色进行查询：

$users = get_users( array( 'role' => 'subscriber' ) );
foreach ( $users as $user ) { 
   $email = get_user_meta($user->ID, "email", true);
   echo $email;
}

允许您按特定角色进行查询：

$users = get_users( array( 'role' => 'subscriber' ) );
foreach ( $users as $user ) { 
   $email = get_user_meta($user->ID, "email", true);
   echo $email;
}

我喜欢使用和的组合。看起来是这样的：

$users = get_users( array( 'role' => 'subscriber' ) );
if( ! empty( $users ) ) {
    $emails = wp_list_pluck( $users, 'user_email' );
}
