How to use vBulletin user database with external PHP scripts?

[Inocybe]

Thanks, this almost work.

Now when people get the vBulletin login page, the image links is broken, and when I enter my user info and press Log In, I'm refered to the wrong page "login.php" (404 Not found) instead of "forums/login.php".

This is the code I use:

PHP Code:

<?php 
chdir('forums/'); 
require_once('./global.php');

if ($vbulletin->userinfo['userid']) 
{ 
    include "include/header.php";
    echo 'Welcome ' . $vbulletin->userinfo['username'] . ', you have logged in.'; 
    include "include/footer.php";
} 
else 
{ 
    // displays vbuletins login/error page 
    print_no_permission();
} 
?>
