hey dhrups
u alrite? lol

if u use the session stuff on ur login page does the login still work?

the thing that is wrong with ur last script is that with this part:

[code]
session_start();

if(!isset($_SESSION[user_id])) { echo "<p><center>Please login to view this page.</p><p> </p> Please wait... You will automatically be redirected back to the login page";
echo "<META HTTP-EQUIV=Refresh CONTENT='3; URL=home.php'>";

} else {
}

[/code]

u need to close the else after ur script so at the end of ur page coz ur saying that if the session isnt set then redirect them to the login page otherwise u let them into the script.
lol hope that helps
if it dont let me know

Change this the top part of scs_admin.php:
[code]<html>

<head>
<title>Administrator Page</title>
</head>

<body>

<?php

require_once("config.php");

?>

<?

session_start();[/code]
to the following:
[code]<?php
session_start();
?>
<html>

<head>
<title>Administrator Page</title>
</head>

<body>

<?php
require_once("config.php");[/code]

Always place session_start as the first line of code in any page that requires sessions. Do not output HTML before the use of session_start otherwise your sessions will fail to work.
