FB.event.subscribe comment.create在没有用户操作的情况下执行 [英] FB.event.subscribe comment.create acting without action from user

问题描述

好的，这里是我的问题。我试图得到一个电子邮件发送给个人的帖子的作者，一旦在Facebook的评论作出评论（通知作者，已作出评论）。评论框位于K2项目（在Joomla中）。

OK, so here is my problem. I'm trying to get an email sent to the author of individual posts once a comments is made in facebook comments (to notify the author that comments have been made). The comment box is in a K2 item (in Joomla).

FB.event.subscribe comment.create正在工作，我尝试过
alert（'fired'）;
和工作正常。但是当我进入PHP它只是开始发送电子邮件给第一个电子邮件给每次有人进入页面。我如何才能在创建或添加评论时发送电子邮件？

FB.event.subscribe comment.create is working, I've tried it with just alert('fired'); and that works fine. But when I enter the PHP it just starts sending emails to the first email given everytime someone enters the page. How do I get it to send email only when a comment is created or added?

<script>
    window.fbAsyncInit = function(){ 
        FB.Event.subscribe('comment.create', function(response){
            <?php
                if ($this->item->author->name = 'Author1'){
                    $to = "[e-mail]";
                }else if ($this->item->author->name = 'author2'){
                    $to = "[e-mail]";
                };
                $subject = "Test mail";
                $message = "Hello! This is a simple email message. live run";
                $from = "[e-mail]";
                $headers = "From:" . $from;
                mail($to,$subject,$message,$headers);
            ?>;
        });
    };
</script>

推荐答案

PHP在服务器端执行。在回调被触发时，PHP已经执行了（当请求页面时）。

PHP is executed server-side. By the time the callback is fired, the PHP has already executed (when the page was requested).

相反，你需要在你的回调中进行一个AJAX调用一个PHP脚本，它可以做任何你需要它做：

Instead, you need to make an AJAX call inside of your callback to a PHP script that will do whatever it is that you need it to do:

window.fbAsyncInit = function(){ 
    FB.Event.subscribe('comment.create', function(response){
        $.post('/sendemail.php');
    });
};

将其余代码放在 sendemail.php

这假设您使用的是jQuery。

This assumes you are using jQuery.

注意：一个很糟糕的想法，考虑到，没有任何验证，用户可以只是发送重复请求到 sendemail.php ，并垃圾邮件从某人的邮箱。考虑安全性，速率限制等。

Note: This is a pretty bad idea considering that, without any validation, a user can just send repeated requests to sendemail.php and spam the heck out of someone's mailbox. Consider security, rate limiting, etc.
