Redirect The User After Login

You read the url you came to login page. It is stored in $_SERVER unless I am mistaken. (I would advise doing print_r($_SERVER) to see what's available) Alternatively, you bring $_SERVER['REQUEST_URI'] to login page as a parameter like so header('login.php?came_from=' + $_SERVER['REQUEST_URI']) when you redirect the user to login. Put it in the form as a hidden input. Then after login, you still have that url as a parameter in the script so you can now easily use header('yourpage.php') to redirect again :)

One option is to store the redirect location somewhere. This can be done in the url or my preferred option: in a hidden field.

store the value of page in cookie

$_COOKIE['visit'] = "http://www.example.com/secret/data/important.php?id=23&pin=2if24scrtw2323"; and then from login header('location: '.$_COOKIE['visit']); 

first you need to check the id and pin value using php GET and POST or REQUEST like $_GET['id']

after successful login you can set values in session like $_SESSION['id'] and redirect thr user on agin or reload the page and check session value is exist or equel to get value

Please check the php manual for the header method, there is an example for redirection.

http://php.net/header

Copy&Paste from there:

<?php header("Location: http://www.example.com/"); /* Redirect browser */ /* Make sure that code below does not get executed when we redirect. */ exit; ?> 

Something like this:

<?php session_start(); if (!$_SESSION['logged_in']) { header('location: login.php'); die; } //other code ?>
