WordPress 评论回复邮件通知

开始之前请确认你的服务器可以使用wp_mail发送邮件，否则以下代码就不用看了。邮件模版写起来和普通网站模版是有些区别的，加上很多旧代码写的真是无法直视……

实现方法：

下面代码加到functions.php中

/**
* mail when reply to someone
*
* @since Pure 1.0
*/
function comment_mail_notify($comment_id) {
$comment = get_comment($comment_id);
$parent_id = $comment->comment_parent ? $comment->comment_parent : ”;
$spam_confirmed = $comment->comment_approved;
$logo = get_template_directory_uri().’/images/logo.png’;//LOGO 地址
if (($parent_id != ”) && ($spam_confirmed != ‘spam’)) {
$wp_email = ‘no-reply@’ . preg_replace(‘#^www/.#’, ”, strtolower($_SERVER[‘SERVER_NAME’])); //可以修改为你自己的邮箱地址
$to = trim(get_comment($parent_id)->comment_author_email);
$subject = ‘你在 [‘ . get_option(“blogname”) . ‘] 的留言有了新回复’;
$message = ‘<table class=”email” style=” width: 600px; margin-top: 10px; margin-right: auto; margin-bottom: 0; margin-left: auto; font-size: 16px; line-height: 1.4;”>
