WordPress实现回复文章评论后发送邮件通知的功能

很多时候，人们都希望在自己的评论被管理员回复后会收到通知。该函数的作用就是回复后自动邮件通知评论者。

把下面的代码加到wordpress的主题函数里面，然后修改下邮件帐号密码。

该函数是针对SAE平台的wordpress，非SAE平台不能使用，有需要的话留言我也会写出相应方法。

  //邮件回复
  function comment_mail_notify($comment_id) {
  define('MAIL_SMTP', 'smtp.exmail.qq.com'); //smtp服务器
  define('MAIL_PORT', 25); //smtp端口
  define('MAIL_SENDEMAIL', '123456789@qq.com'); //发送邮件帐号
  define('MAIL_PASSWORD', '123456'); //发送邮件密码
  $admin_notify = '1';
  $admin_email = get_bloginfo ('admin_email');
  $comment = get_comment($comment_id);
  $comment_author_email = trim($comment->comment_author_email);
  $parent_id = $comment->comment_parent ? $comment->comment_parent : '';
  global $wpdb;
  if ($wpdb->query("Describe {$wpdb->comments} comment_mail_notify") == '')
  $wpdb->query("ALTER TABLE {$wpdb->comments} ADD COLUMN comment_mail_notify TINYINT NOT NULL DEFAULT 0;");
  if (($comment_author_email != $admin_email && isset($_POST['comment_mail_notify'])) || ($comment_author_email == $admin_email && $admin_notify == '1'))
  $wpdb->query("UPDATE {$wpdb->comments} SET comment_mail_notify='1' WHERE comment_ID='$comment_id'");
  $notify = $parent_id ? '1' : '0';
  $spam_confirmed = $comment->comment_approved;
  if ($parent_id != '' && $spam_confirmed != 'spam' && $notify == '1') {
  $wp_email = 'no-reply@' . preg_replace('#^www\.#', '', strtolower($_SERVER['SERVER_NAME']));
  $to = trim(get_comment($parent_id)->comment_author_email);
  $subject = '你在' . get_option("blogname") . '回复被关注啦~';
  $message = '
