If he is admin, then he will redirect to admin home page & If he is user, will redirect to user home page. but my problem is when I set session to the admin homepage or user homepage, it does not work. there is a code named "homepage.php" That I use to create session in the admin homepage. without this part, after login, user enter to the homepage. But with this part user reditect to the index.php page always. Where is the problem in my code? homepage.php

<?php
session_start();
if(!isset($_SESSION["sess_user"]) || $_SESSION['sess_user']!='1')
