登录PHP后如何进入同一页面 [英] how to go to the same page after login in PHP

问题描述

例如

步骤1:

我正在浏览的页面没有登录，登录前的最后一页是beforeLogin.php

I am browsing a page without logging in and my last page before logging in is beforeLogin.php

步骤2:

现在我的问题是当我登录时将重定向到index.php页面.相反，我应该重定向到我浏览过的最后一页.

Now my prob is when i logged in i am redirecting to the index.php page. Instead i should be redirected to the last page what i had browsed.

这是从上面的示例应重定向到beforeLogin.php

That is from the above example is should redirected to beforeLogin.php

这应该怎么做.

任何帮助都是有意义的.

Any help will be appreciable.

预先感谢

推荐答案

您将需要一种跟踪所访问网页的方法，以便可以向后引用用户浏览过的最后一页.

You would need a way to keep track of the web pages visited, so you can back-reference to the last page the user has browsed to.

当我想到跨多个页面跟踪用户的 session 时，我像其他所有PHP程序员一样，想到使用

When I think of tracking a user's session across multiple-pages I, like every other PHP programmer, think of using sessions.

一种可能的方法是将访问的链接存储到会话变量中，然后当用户到达login.php页面(要登录的页面)时，提供

A possible way could be to store the link visited into a session variable and then when the user reaches the login.php page (the page to login into) provide a header redirect to $url given by the session variable.

您可以将此代码粘贴到网站上的所有页面中:

You can paste this code into all your pages on your website:

<?php
session_start(); // starts the session
$_SESSION['url'] = $_SERVER['REQUEST_URI']; // i.e. "about.php"

这利用 $_SERVER 变量返回使用$_SERVER['REQUEST_URI']

然后在登录页面上帮助进一步演示:

And then for the login page to help further demonstrate:

<?php
session_start();  // needed for sessions.
if(isset($_SESSION['url'])) 
   $url = $_SESSION['url']; // holds url for last page visited.
else 
   $url = "index.php"; // default page for 

header("Location: http://example.com/$url"); // perform correct redirect.
