Passing additional variables to page using vB authorisation

[RedFive]

Hi all,

I have successfully set up a members' area on my site which uses vB as the authorisation and member list. It all works rather well, except for when I want to pass additional variables to a page using this system.

I am using the code from https://vborg.vbsupport.ru/showthread.php?t=61112 to log in to the members' area. I'm running vB 3.5.

The problem comes when I have a page that requires additional variables to be passed, eg: http://example.com/members/index.php?my_id=1. vB seems to nullify all variables being sent that are not vB variables. I am aware of the reasons for doing so, but don't know of a sensible way of retaining the values of my variables. for use later in the php script.

Specifically, the code I am using at the top of each member's page is as follows:

PHP Code:

/* value for $my_id is passed in url, eg: test.php?my_id=1 */

chdir("/path/to/public_html/forum/");
require('./global.php'); 
chdir("/path/to/public_html/members/");

if ($vbulletin->userinfo['userid']==0)
{
    require('/path/to/public_html/members/login.php');
    exit;
}

/* At this point, $my_id is empty */ 


Can you assist please?

Many thanks in advance.
