Login and Logout Authentication for a Project Management Application - The Script (
Page 4 of 4 )
This is how your entire logout script should look:
<?
ob_start();
include "dbcon.php";
//update the users table
if(isset($_SESSION['name'])){
$uname =$_SESSION['name'];
$save = "UPDATE users SET lastlogin ='".$td."'";
mysql_query($save);
//destroy session
session_start();
session_unset();
session_destroy();
}else{
//user is not suppose to be on this page
//redirect to login page
header("location:login.php");
}
?>
