我怎样才能让会话变量持续跨越标题重定向？ [英] How can I get session variables to persist across header redirects?

问题描述

我的标题重定向如下所示： header（Location：./ content / user_dash.php）;

我有 session_start（）; 在每一页的顶部。

我已经尝试过我的标题重定向 session_regenerate_id（true）; $ b

我已经在我的头文件之前和session_regenerate_id重定向之后尝试了 session_write_close（）;

我试过 exit（0）; 和 die（）; after我的头重定向;

我试过头（Location：./ content / user_dash.php？PHPSESSID =。session_id（））;

如果我包含结束页面，它可以工作（但我不能使用它），并且当我更改它以重定向我的变量时停止工作。我通过$ _SESSION通过foreach循环测试了它，并且在包含页面时打印，但不在重定向。

我有点拉我的头发因为我确实需要在重定向后使用会话变量。

文件结构：

index.php = submits login form => login_code.php =在设置session vars => user_dash.php后重定向echos vars并没有显示（空vars，如果语句要回显ifset）

I已删除重定向，甚至简单的超链接都不会将我的会话变量带到下一页。

解决方案

您需要调试您的应用程序。

这对你来说可能是一个惊喜，但调试需要大部分程序员时间。所以，有时间去学习一些真正的程序员的工作。

  header（Location：./ content / user_dash.php？。session_name（）。=。session_id（） ）; 
  

与 session_write_close（）一起使用是最防弹的方式如果它仍然不能正常工作，那么就开始调试吧。
$ b

• 检查会话文件


• 检查cookie


• 检查ini设置


• 检查user_dash.php中的会话ID - 是否一样？


• 检查您是否真的失去了所有会话或可能只是一个变量

谢谢为ini设置。
我可以看到2个可疑人物

• session.use_only_cookies表示通过url发送SID将不起作用。重新检查会话cookie
  
• session.cache_expire 180 180太小。

和I可能会忽略一些，因为我没有为调试您的应用程序付费，我有我自己的工作要完成。
所以，我只是建议让所有设置都是默认设置，并且在你知道你在做什么之前不要触摸它们。

How can I get session variables to persist across header redirects?

My header redirect looks like this: header("Location:./content/user_dash.php");

I have session_start(); at the top of every page.

I have tried before my header redirect session_regenerate_id(true);

I have tried before my header and after session_regenerate_id redirect session_write_close();

I have tried exit(0); and die(); after my header redirect;

I have tried header("Location:./content/user_dash.php?PHPSESSID=".session_id());

If I INCLUDE the end page it works (But I cannot use this) and when I change it to redirect my variables stop working. I tested this with a foreach loop through $_SESSION and it prints when INCLUDING the page, but doesn't on redirect.

I'm kinda pulling my hair out over this because I really do need to use session variables after redirects.

File Structure:

index.php = submits login form => login_code.php = redirects after setting session vars => user_dash.php echos vars and nothing shows (empty vars, if statement to echo if isset)

I have removed the redirects and even simple hyperlinks aren't carrying my session variables to the next page.

解决方案

You need to debug your application.

It could be a surprise for you, but debugging takes most of the programmers time. So, time to learn some of the real programmers job.

header("Location:./content/user_dash.php?".session_name()."=".session_id());

used along with session_write_close() is a most bulletproof way

if it's still not working start debugging it.

• check the session file
• check the cookies
• check ini settings
• check session id in the user_dash.php - is it the same?
• check if you really lose all your session or may be just one variable

thank you for the ini settings. I can see 2 suspicious ones

• session.use_only_cookies On means sending SID via url will have no effect. check session cookies AGAIN
• session.cache_expire 180 180 is way too small.

and I may overlooked some as I got not paid for the debugging your app and I have my own job to be done. So, I'd just suggest to make all settings default and never touch them until you got to know what are you doing certainly
