当新用户注册时，会收到确认电子邮件，上面写着：
Username: testuser To set your password, visit the following address:
但我想对其进行自定义，因此我将以下代码添加到
functions.php但它不起作用。默认电子邮件仍会发送。
我正在使用WordPress 4.9.9
<?php
add_filter( \'wp_new_user_notification_email\', \'custom_wp_new_user_notification_email\', 10, 3 );
function custom_wp_new_user_notification_email( $wp_new_user_notification_email, $user, $blogname ) {
$wp_new_user_notification_email[\'subject\'] = sprintf(__( \'[%s] Your username and password\' ), $blogname, $user->user_login );
$key = get_password_reset_key( $user );
$message = sprintf(__(\'Welcome to our website,\')) . "\\r\\n\\r\\n";
$message .= \'To set your password, visit the following address:\' . "\\r\\n\\r\\n";
$message .= network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user->user_login), \'login\') . "\\r\\n\\r\\n";
$message .= "After this you can enjoy our website!" . "\\r\\n\\r\\n";
$message .= "Kind regards," . "\\r\\n";
$message .= "Support Team" . "\\r\\n";
$wp_new_user_notification_email[\'message\'] = $message;
$wp_new_user_notification_email[\'headers\'] = \'From: MyName<[email protected]>\';
// this just changes the sender name and email to whatever you want (instead of the default WordPress <[email protected]>
return $wp_new_user_notification_email;
}
?>
为什么代码不起作用？你能帮帮我吗？

实际上，您所使用的代码没有任何问题（我按照上面的代码进行了测试，效果很好）。
但您必须考虑一些其他可能性：
在wp_new_user_notification() 函数是一个可插入函数。因此，它可以被插件或自定义代码替代。如果它被替换，则该函数的自定义版本可能缺少wp_new_user_notification_email 过滤器挂钩wp_new_user_notification().
查看主题，确保这是wp_new_user_notification_email 过滤器
