discuz回贴通知插件实现-获取邮件内容

//自定义钩子函数，命名：模块_函数名_output()或模块_函数名()
//一个是模块执行完，模板输出前执行。一个是模块执行前
//post_reply_output函数会在所有post操作中都会执行，通过$params['message']来区别
public function post_reply_output($params) {
    global $_G;

    //判断是否为主题回复成功时
    if($params['message'] != 'post_reply_succeed') {
        return;
    }

    //如果操作的是系统表，先获得系统表的模型，
    //在discuz目录的source/class/table下
    $mForumThread = C::t('forum_thread');
    $tid = $params['values']['tid'];
    $thread = $mForumThread->fetch($tid);
    //主题作者ID

    //判断作者是否开启回贴通知
    $mForumPostNotice = C::t('#post_notice#forum_post_notice');
