Integrating external script with vB

[MoMan]

Hi,

I currently integrate my homepage with vbulletin in order to fetch user login and session data. The code I use to do that is as follows:

PHP Code:

// Integrate with vbulletin if requested
    if (defined('VB_CONNECT'))
    {
        define('DISABLE_HOOKS', true);
        define('LOCATION_BYPASS', 1);
        chdir(VB_DIR);
        require_once('global.php');
        chdir(BASE_DIR);
    } 


...and it works like a charm. However, when I wrap that in a function, like so:

PHP Code:

function logIn()
{
    // Integrate with vbulletin if requested
    if (defined('VB_CONNECT'))
    {
        define('DISABLE_HOOKS', true);
        define('LOCATION_BYPASS', 1);
        chdir(VB_DIR);
        require_once('global.php');
        chdir(BASE_DIR);
    }
}

logIn(); 


Everything mysteriously blows up and I get the following PHP error:

PHP Fatal error: Call to a member function query_first_slave() on a non-object in [DIR]/forums/includes/functions.php on line 1386

Where line 1386 uses $vbulletin->db->query_first_slave to fetch the userinfo.

Any ideas why this could be? Is it a scope issue?

As a temporary workaround, I've simply placed the code in a separate file and include it whenever I need the integration. I know that a better solution would be to connect to the database only to fetch user data and use my own session, but for now I want to keep things quick and dirty (and secure)
