PHP会话和Ajax [英] PHP session and Ajax

问题描述

我创建一个会话变量并存储在一个值123456。 我需要另一个网页，使用AJAX呼吁该值。使Ajax调用时，我无法访问会话变量。在session_start（）是在两页的顶部。我甚至试着写的实际会话值从阿贾克斯函数调用的页面txt文件，但该文件竟然一片空白。

I've created a session variable and stored a value "123456" in it. I need that value on another page that is called using ajax. I cannot access the session variable when making the ajax call. session_start() is in top of both pages. I even tried to write the actual session value to a txt file from the page that the ajax function calls, but the file turned out blank.

怎么办？

推荐答案

您不能访问从Javascript PHP的会话信息（我假定这就是你想要做的事）。您可以将它作为一个隐藏字段或JS（用PHP动态添加）到第二页，将其添加到普通饼干，或从PHP提供它作为一个AJAX请求的响应，但我认为这些都是你唯一的选择。

You cannot access PHP session info from Javascript (I'm assuming that this is what you're trying to do). You can pass it in as a hidden field or in the JS (dynamically added with PHP) to the second page, add it to a regular cookie, or provide it from PHP as a response to an AJAX request, but I think those are your only options.
