Problems with: $vbulletin->userinfo['userid'];

[cashaddy]

Hey mates,

got a small problem, which is already transformed to a major one...

i want to add a login box to my wordpress frontend, and if the user is logged in to the forum it should display a welcome message and some related stuff...

main facts:

i am including the global.php while using this code (added it to the header.php in wordpress. that it's openend on every page):

if (!file_exists('/path/forum/global.php')) { echo "++++ IT!";
exit; }

require_once('/path/forum/global.php');


got that code in my sidebar:

$userid=$vbulletin->userinfo['userid'];
echo '"'.$userid.'"';

the result i get: "" => that means, i can't read the userid of a logged in user.

got any tipps? would be pretty happy if yes
