非插件方式实现wordpress评论回复的邮件通知, 效果类同同站博客评论回复

function comment_mail_notify($comment_id) {
  $admin_notify = ‘1’; // admin 要不要回复通知 ( ‘1’=要 ; ‘0’=不要 )
  $admin_email = get_bloginfo (‘admin_email’); // $admin_email 可改为你指定的 e-mail.
  $comment = get_comment($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 = $parent_id ? get_comment($parent_id)->comment_mail_notify : ‘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’])); // 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") . ‘] 的留言有了回应’;
    $message = ‘
