Hi All,

 

I hope someone can point out the obvious with this one.

 

I've a CMS which has 2 account types:

- Admin

- Basic

 

If you're logged in as an admin, you can edit a user and you've access to other parts of the CMS

If you're logged in as a basic user, you just get access to 1 page

 

My problem is, when I edit a user with basic access, as soon as I go into the edit user screen, the CMS removes all access as if you were logged in as the basic user.

 

There are 3 parts to the script

- header

- edit_user

- footer

 

Header contains

// This page begins the HTML header for the site.

// Start output buffering.
ob_start();

// Initialize a session.
session_start();

 

edit_user contains

<?php

// This page edits a users profile
// This page is accessed through view_users.php.

// Include the configuration file for error management and such.
require_once ('includes/config.inc.php'); 

// Set the page title and include the HTML header.
$page_title = 'Edit A Profile';
include ('includes/header.html');
  
// If no first_name variable exists, redirect the user.

if (!isset($_SESSION['name'])) {

// Start defining the URL.
$url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']);
// Check for a trailing slash.
if ((substr($url, -1) == '/') OR (substr($url, -1) == '\\') ) {
	$url = substr ($url, 0, -1); // Chop off the slash.
}
// Add the page.
$url .= '/index.php';

ob_end_clean(); // Delete the buffer.
header("Location: $url");
exit(); // Quit the script.

} else {
?>
