Problem:- Control Over User Login Procedure – Cookies Authentication

Solution:-

This is HTML code of Login Form. Save as User.php

User.php file

<form method="POST" action="login.php">
 <input type="text" name="username"><br>
 <input type="password" name="password"><br>
 <input type="submit" name="login" value="Login">
</form>

Login.php File

This is the Login.php file. Here we use Cookies function to store information but if you want to use session then just change the setcookie function.

<?php
error_reporting(0);
function validate($user, $pass){
 if ($user == "Deep" && $pass=="123456") {
  return true;
 }else{
 header("Location: test.php ");
}

}

if (isset($_POST['login'])) {

$secretWord = "this is cool";
if (validate($_POST['username'], $_POST['password'])) {
 setcookie('login', $_POST['username'].",".md5($_POST['username'].$secretWord));
}
}
unset($username);
if (isset($_COOKIE['login'])) {
 list($c_username, $cookie_hash) = explode(',', $_COOKIE['login']);
 if (md5($c_username.$secretWord) == $cookie_hash) {
  $username = $c_username;
 }
}else{
  echo("You sent a unreconized request <br>");
 }
if (isset($username)) {
 print "Welcome, $username";
}
else{
 ?>
 <script type="text/javascript">
  alert("Welcome, You'r Not a Reconized User");
  window.location.href = "test.php";
</script>
 <?php
}



 ?>
