如何确定发送到PHP脚本的POST数据来自何处？

Question

I have a ton of data collection forms on my website, and I wrote a PHP script to handle all the data. All the forms have that one script as their action, and POST as the method. The handler emails a copy of the data to me, and I'd like for the emails I get to contain the URL of the form where they originated. Is there any way in PHP to get the url of the form which was submitted to the script? Or do I have to add an extra hidden field in every form with its URL?

Answer 1

同样在电子邮件中发送以下变量：

$_SERVER['HTTP_REFERER'] 

Answer 2

如果要确保帖子仅来自您自己的表单，则可以在表单的隐藏字段中放置一次性令牌以进行验证。
