WordPress添加回复评论邮件通知

前言

之前就想要弄这个功能了，但是主题不支持，今天果核更新了主题终于支持了

教程

将如下代码放到子主题的function.php 中即可

function comment_mail_notify($comment_id) {
  $comment = get_comment($comment_id);
  $parent_id = $comment->comment_parent ? $comment->comment_parent : '';
  $spam_confirmed = $comment->comment_approved;
  if (($parent_id != '') && ($spam_confirmed != 'spam')) {
    $wp_email = 'no-reply@' . preg_replace('#^www.#', '', strtolower($_SERVER['SERVER_NAME'])); //e-mail 发出点, no-reply 可改为可用的 e-mail.
    $to = trim(get_comment($parent_id)->comment_author_email);
    $subject = '您在 [' . get_option("blogname") . '] 的留言有了回复';
    $comment_link = get_comment_link($comment_id); // 获取评论链接
    $message = '<div style="border-right:#666666 1px solid;border-radius:8px;color:#111;font-size:12px;width:95%;border-bottom:#666666 1px solid;font-family:微软雅黑,arial;margin:10px auto 0px;border-top:#666666 1px solid;border-left:#666666 1px solid"><div class="adM">
