My News Script [No errors] - Just wont work!
The problem is that when i try to visit edit?=1 or addnews.php
it redirects me to index.php and it should only do that if i am not logged in which i am.. so what is the problem :S?
Index.php
PHP Code:
<?php
// Turn on error reporting and start the session
error_reporting(E_ALL);
session_start();
include('lib_class/db_class_connect.php');
$database_connection = new db_connect();
//Look for our logged status, if not found redirect the user
if($_SESSION['logged'] != 1)
{
//header("Location: users.php");
exit();
}
define('DEBUG', 1);
?>

$result = mysql_query($q);
if( ! $result)
{
if (defined('DEBUG'))
{
echo $q; // so we can verify the query was properly formatted. Not really necessary here, but useful when you
// you're using dyanmically created query strings (such as those using $_GET variables)
echo mysql_error(); // Useful for debugging, but for a live site this will give useful information to a potential hacker, just so you know.
