Implementation ideas and code for PHP users to jump back to the previous visited page after logging in

Project requirements

When visiting the website page , some pages require authorization to access. At this time, the user will be asked to log in and jump to the login page login.php. How to return to the page just visited after logging in.

Solution 1:

Before jumping to the login page, save the URL of the currently visited page in the cookie. After the login verification authorization is passed, from the cookie Take out the url value and jump to the page specified by the url.

Specific implementation method:

While prompting the user to log in, record the URL of the requested page in the session or cookie; after successful login verification, jump back to the URL.

checklogin.php

The code is as follows:

session_start();
if (!isset ($_SESSION['login_ok']))
{
echo "<script language=javascript>alert (&#39;要访问的页面需要先登录。&#39;);</script>";
$_SESSION[&#39;userurl&#39;] = $_SERVER[&#39;REQUEST_URI&#39;];
echo &#39;<script language=javascript>window.location.href="login.php"</script>&#39;;
}
login.php
代码如下:
session_start();
//此处省略了账号密码验证代码，验证OK再执行下面代码
if (isset ($_SESSION[&#39;userurl&#39;]))
{
//会话中有要跳转的页面
$url = $_SESSION[&#39;userurl&#39;];
}
else
{
//没有要跳转的页面，则转到首页
$url = "home.php";
}
//0.5s后跳转
echo "<meta http-equiv="refresh" content="0.5;url=$url">";

Solution 2:

In addition to saving in cookie form, I believe everyone I have also seen that many large websites directly use GET to obtain data. This is the login mechanism of DZ.

The specific idea is as follows:

Before jumping to the login page, the URL of the page visited by the visitor must be passed as a parameter. After login verification, jump after granting access rights. Go to the page specified by this url.

For example, the URL before logging in is: http://www.xxx.com/member/authpage.html. When a visitor visits and clicks No Permission, the address that jumps to the login page is login.php? redirect_url=http://www.xxx.com/member/authpage.html, so that when logging in, you can use GET to obtain the parameter http://www.xxx.com/member/authpage.html. After the login verification is successful, Just jump to the authpage.html page.
