无法读取前一个请求AJAX设置的$ _SESSION变量 [英] Can't read $_SESSION variables set by previous request, AJAX

问题描述

我的页面加载，并调用一个init（）函数，该函数将内容返回到页面上的

div，以及设置$ _SESSION变量。它返回的内容

包含一个调用相同变量的链接，但是我得到一个

错误，表示索引没有定义。


后两个调用是AJAX生成的。第二次调用

在设置它之后回复$ _SESSION变量，并将其设置为正确的
。但随后的请求并没有看到它。


我无法想出这一点，这种功能对于

至关重要我正在建设。


我已经完成的事情：


将session_start（）放入后调用的函数中最初的

页面加载。只是生成会话已经启动的警告（原始页面加载）。


选中以确保所有请求都使用相同的会话，

，它是（根据session_id）。


任何帮助表示赞赏。

My page loads, and calls an init() function that returns content to a
div on the page, as well as setting a $_SESSION variable. The content
it returns includes a link that calls the same variable, but I get an
error that says the index isn''t defined.

The second two calls are AJAX-generated. The second call immediately
echos the $_SESSION variable back after it sets it, and it sets it
properly. But the subsequent request doesn''t see it.

I can''t figure this one out, and this sort of function is vital to the
site I''m building.

Things I''ve already done:

Put session_start() in the functions that get called after the initial
pageload. Just generates warnings that a session has already been
started (by the original pageload).

Checked to make sure the same session is being used by all requests,
and it is (according to session_id).

Any help is appreciated.
