PHP Changes to WOL for New Forum Home Page

Wrote some PHP code today to make the Who Is Online (WOL) in the forums work properly with the new home page:

Wrote this global plugin to add the location to both the user table (for members) and session table (for guests + registered users)

<?php
if (THIS_SCRIPT != 'misc' and THIS_SCRIPT != 'ajax') { 

    $mylocation = THIS_SCRIPT; 
    if (strlen($mylocation) < 2) { 
        $mylocation = "unknown"; 
    } 

    if ($vbulletin->userinfo['userid'] > '0') { 

        $query = "UPDATE " . TABLE_PREFIX . "user SET parentemail = '" . $mylocation . "' WHERE userid = " . $vbulletin->userinfo['userid']; 
        if (false) { 
            error_log("UID: " . $vbulletin->userinfo['userid'] . ' loc_cookie ' . $mylocation . " query: " . $query . "\n", 3, '/var/log/apache2/debug/cookiesetdbupdate.log'); 
        } 

        $db->query_write($query); 
    } 

    // borrowed  unused incalendar DB column  in the session table until I have a change to create a new one

    if (isset($vbulletin->session->vars['sessionhash']) and strlen($vbulletin->session->vars['sessionhash']) > 10) { 
        $query = "UPDATE " . TABLE_PREFIX . " session SET incalendar = '" . $mylocation . "' WHERE sessionhash = '" . $vbulletin->session->vars['sessionhash'] . "'"; 
        if (false) { 
            error_log("UID: " . $vbulletin->userinfo['userid'] . ' loc_cookie ' . $mylocation . " query: " . $query . "\n", 3, '/var/log/apache2/debug/cookiesetdbupdate.log'); 
        } 

        $db->query_write($query); 

    } 

} 

In addition, wrote some quick PHP code for the online.php in functions_online.php :

<?php

case 'index':

        if($userinfo[userid] > '0')
        {
            $query = "SELECT lastlocation,lastactivity FROM " . TABLE_PREFIX . "user WHERE userid = ".$userinfo[userid]." ORDER BY lastactivity DESC LIMIT 1";
            $userloc = $vbulletin->db->query_first("SELECT lastlocation,lastactivity FROM " . TABLE_PREFIX . "user WHERE userid = ".$userinfo['userid']." ORDER BY lastactivity DESC LIMIT 1");
            error_log("UID: " . $vbulletin->userinfo['userid'] . '  loc ' . $userloc['lastlocation'] . ' Query: '.$query. "\n", 3, '/var/log/apache2/debug/online_neo.log');
        }
        else
        {
            if(strlen($vbulletin->session->vars['incalendar']) > 10)
            $guestloc = $vbulletin->session->vars['incalendar'];
        }

     

        if($userloc['lastlocation'] == 'home' OR $guestloc == 'home')
        {              
             $userinfo['action'] =  'Viewing Home Page - Featured Discussion';
             $userinfo['where'] = '<a href="' . $vbulletin->options['forumhome'] . '.php' . $vbulletin->session->vars['sessionurl_q'] . '">' . $vbulletin->options['bbtitle'] . '</a>';
        }
        else
        {                 
            $userinfo['action'] = 'Viewing Forum Home and Stats Page';
            $userinfo['where'] = '<a href="https://www.unix.com/forum.php' . $vbulletin->session->vars['sessionurl_q'] . '">Forums: ' .$vbulletin->options['bbtitle'] . '</a>';
        }
                
       break;
