so the page protection code I finally got to work is working properly in all the browsers however with safari after I log out i can click the back button and get into the protected pages and change things, however once the submit button is hit or the page is left a second time, then the protection kicks in, however this is to late if someone has already made the changes that they want to. Anyone with any ideas to fix this? here is the code protecting the page:
<?php
session_start();
include 'conection_code.php';
if(isset($_SESSION['user_id']))
{
?>
Web page code is placed here, then there is an else statment.
<?php
}else
{
echo "<br /><br /><br /><br />";
echo "<strong><center>"."You Are Not Authorized To view This Page......<a href='admin.php'>Please Login First !!</a>"."</center></strong>";
}
?>
