I'll pay an additional $10
Okay I got impatient and played around, after a while I narrowed it down. In includes/init.php the following sets the session info in the cookie:
PHP Code:
$vbulletin->session->do_lastvisit_update($vbulletin->GPC[COOKIE_PREFIX . 'lastvisit'], $vbulletin->GPC[COOKIE_PREFIX . 'lastactivity']);
So basically this is all registering will do, login will add the additional username and password. So in init.php right under that line of code i just added
PHP Code:
vbsetcookie('userid', $vbulletin->userinfo['userid']);
vbsetcookie('password', md5($vbulletin->userinfo['password'] . COOKIE_SALT));
Seems a bit sloppy, but it works fine, so ill stick with it until someone else figures out a better way.
