Just wanting to know the correct code to use to add to a foreign script.
To ensure that only registered users are capable of viewing what i offer?

A custom php script.
For example if i am to create a script and place it in the root directory then i would like to be able to prevent non registered users from viewing the page.

And is the global.php script included in your custom script? I fyou have that script included, then you can use basic vbulletin code.

Yes i tried to include the global file but it throws an error as below.

Warning: require(./includes/class_bootstrap.php) [function.require]: failed to open stream: No such file or directory in /home/ftwforum/public_html/global.php on line 15

So i assume this is because i am using a directory instead of the root for my script location?

Anyone got any ideas what i am doing wrong?
I can get it to work in the root directory using the below code.

PHP Code:

<?php 
require_once('./global.php'); 
if ($vbulletin->userinfo['userid']!=0) {
  echo "Welcome Back, <b>"; 
  echo $vbulletin->userinfo['username'];  
  } else {
  echo "Sorry No Joy, <b>";
  }
 ?>

But if i try this in a lower directory and change the location to global.php to ../global.php i get errors.

Normally errors like this.

Warning: require(./includes/class_bootstrap.php) [function.require]: failed to open stream: No such file or directory in /home/ftwforum/public_html/global.php on line 15

Now i tried defining the root like so.
define( ROOT_PATH , "./" );
But that did nothing either.
I know this is a simple answer but i am really not that good with PHP and even less skilled with VB. So any help here would be appreciated.
