基于用户会话的重定向周期

发布于 2024-12-07 15:52:41 字数 297 浏览 0 评论 0原文

我在重定向到页面时遇到问题。看起来它正在多次重定向自身。我的标题中有

if(!isset($_SESSION)){
header("location:index.php");
exit();
}

。我的标题包含在我的索引页和其他任何地方。我知道，由于它位于标头中，因此它将被重定向到index.php，然后它会一遍又一遍地执行脚本，这给我带来了问题。

我如何防止它在重定向后立即停止执行此操作？或者是否有另一种方法来检查用户是否登录，如果没有，则转到index.php？

谢谢！

I have a problem with redirecting to a page. It seems like it is redirecting itself multiple times. I have

if(!isset($_SESSION)){
header("location:index.php");
exit();
}

in my header. and my header is included in my index page and everywhere else. I know that since it is in the header, it will be redirected to index.php then it will the script again and over and over which is giving me problems.

How would I prevent it to stop doing it right after redirecting? Or is there another way to check if user is logged in, if not, go to index.php?

Thanks!

首先，您不应该检查 SESSION 数组本身是否已完整设置。您应该只分配一两个索引并检查它们。这样，您将永远无法逃脱重定向，因为您甚至无法分配 SESSION。

您需要分配类似 $_SESSION['authorized'] = TRUE; 的内容； 登录成功后，然后在每个页面上检查该索引是否已设置、是否为 TRUE，并进行相应操作。
另外，您应该重定向到登录页面或类似的页面...您应该提供实际登录用户的可能性！当然，除非您的登录表单不在索引页面中，但您没有指定该信息...

if(isset($_SESSION['authorized']) AND ($_SESSION['authorized'] === TRUE)
{
   //ok, user is logged. Redirect somewhere else? Do something specific?
}
else
{
   header("Location:index.php"); // or redirect to login.php, for example
   exit();
}

此外，请记住在所有页面中首先调用 session_start()您希望使用会话。

You should not check for the SESSION array itself to be set in its entirety, for starter. You should just assign one or two indexes and check against them. In this way, you won't ever escape the redirect, since you're not even given the possibility to assign a SESSION..

You need to assign something like $_SESSION['authorized'] = TRUE; upon succesful login, and than, on every page, check if this index is set, is TRUE, and act accordingly.
Also, you should redirect to a login page, or something like that...you should give the possibility to actually login to the user! Unless your login form isn't in the index page, of course, but you didn't specify that information...

if(isset($_SESSION['authorized']) AND ($_SESSION['authorized'] === TRUE)
{
   //ok, user is logged. Redirect somewhere else? Do something specific?
}
else
{
   header("Location:index.php"); // or redirect to login.php, for example
   exit();
}

Also, remember to call session_start() as the first thing in all your pages where you want Sessions to be used.
