Check if user logged in and then perform script

[skogen]

I just upgraded to vb 3.5.3 and to my site I have a download script that checks if user logged in in our forum if they want to download files.

I have checked the info here https://vborg.vbsupport.ru/showthread.php?t=98009

but I still got errors

The code for the check-script looks like this

<?php 
  require_once('./global.php');
  if (!$vbulletin->userinfo['userid']) 
{ 
        print_no_permission(); 
}  
  
  if (!$bbuserinfo['userid']);                                     
    
{
    // CODE TO EXECUTE IF USER IS LOGGED IN
 
    // system path to files windows full path ie: 'c:/www/docs/files/' 

    $system = 'http://www.myserver.com/myfiles'; 

    // url to the files directory! 

    $url = 'http://www.myserver.com/myfiles/'; 


    if ( ! empty ( $_REQUEST['asset'] ) )
    { 
        header ( 'Location: ' . $url . $_REQUEST['asset'] ); 

        exit (); 
    } 
    else if ( empty ( $_REQUEST['asset'] ) ) 
    { 
        echo 'no valid file request sent'; 
    } 
    else 
    { 
        echo 'file not found';
   
    } 
 }
?>

The error I got now is

Notice: Undefined index: REQUEST_URI in C:\Inetpub\wwwroot\forum\includes\class_core.php on line 1906
