PHP会话无法正常工作 [英] PHP session is not working
问题描述
我正在使用wamp2.0 - PHP 5.3，apache 2.2.11，但我的会话不存储数据。
I am working with wamp2.0 - PHP 5.3, apache 2.2.11 but my sessions are not storing data.
我有一个接受参数的页面，哪个（简化版）我想在会话中存储，所以当我来到
I have a page that accepts a parameter, which (simplified version) I wanna store in a session, so when I come to
http://www.example.com/home.php?sessid=db_session_id
脚本如下：
session_start();
$sessid = @$_GET['sessid'];
if ($sessid) {
$_SESSION['sessid'] = $sessid;
}
var_dump($_SESSION);
和输出：
array(1) { [0]=> string(13) "db_session_id" }
这很好，但是当我去链接（没有sessid参数） $ _ SESSION 数组是空的。我的事件试图在没有参数的页面之前评论 $ _ SESSION ['sessid'] = $ sessid; 行，但它仍然没有用。
which is fine, but then, when I go to link (without the sessid parameter) the $_SESSION array is empty. I've event tried to comment the $_SESSION['sessid'] = $sessid; line before going to the page without the parameter, but still it didin't work.
我检查了 session_id（）输出，会话ID保持不变。
I've checked the session_id() output and the session id remains the same.

编辑：
会话被iframe删除。我不知道为什么，但是当
评论时，会话工作正常。事实上，iframe必须保持
（当然这很糟糕，但我对此无能为力）。
嗯...你知道任何使用iframe让会话工作
的变通办法吗？
The sessions are deleted by an iframe. I don't know why, but when commented, the sessions work fine. Thing is, the iframe has to stay there (which of course is bad, but I can't do anything about it). Well...do you know about any workarounds to get the sessions working with an iframe?
推荐答案
只有当帧相对于同一个域时，才能访问该会话。例如：
A frame can access the session only if it's relative to the same domain. For example:
<?
$_SESSION["foo"]="foo";
?><html>
<body>
<iframe src ="test.php" width="200" height="200"></iframe>
</body>
</html>
<?
print_r($_SESSION);
?>
应该在iframe外部和内部工作。如果您仍然遇到问题，请尝试：
Should work outside and inside the iframe. If your still having problems try:
<?php session_start();
$sessid = $_GET['sessid'];
if (isset($sessid) && $sessid != "" && $sessid != NULL) {
$_SESSION['sessid'] = $sessid;
}
print_r($_SESSION);?>
