Hide function for forum hep needed. :)

Hi, I have modified my code for my modded phpbb forum, and I just have a quick question and if its a possible one.

My hide 'hack' currently is set to hide the hidden content (using [hide] tags) from everybody except: admins/mods, and those with over 50 posts. Is it possible to also add to that exceptions list that if someone is referred from a certain site (google.com) then they can see the hidden content as well?

Here is my code:

   1. if($item['iteration'] > 1)  
   2.            {  
   3.                return $error;  
   4.            }  
   5.            global $db, $topic_id, $userdata, $mode;  
   6.            $show = false;  
   7.            if($userdata['session_logged_in'])  
   8.            {  
   9.                $sql = "SELECT p.poster_id, p.topic_id  
  10.                    FROM " . POSTS_TABLE . " p  
  11.                    WHERE p.topic_id = $topic_id  
  12.                    AND p.poster_id = " . $userdata['user_id'];  
  13.                $resultat = $db->sql_query($sql);  
  14.                $show = $db->sql_numrows($resultat) ? true : false;  
  15.                if ( ($userdata['user_level'] == ADMIN) || ($userdata['user_level'] == MOD) || ($userdata['user_posts'] > 50))  
  16.                {  
  17.                    $show = true;  
  18.                } 

Code (markup):

 

You can do a check on the HTTP_REQUEST for a sudden domain. If it matches, flag it to true. Then append it to the IF statement.

if (($ApprovedSites)||($userdata['session_logged_in']))

 

Thanks, can you tell me what code to put in to check for the HTTP_REQUEST...or a site that explains this? I hardly know php.

 

http://php.net/reserved.variables

<?php
if($_SERVER['HTTP_REFERER'] != ''){
$URL = parse_url($_SERVER['HTTP_REFERER']);
echo "Welcome, <b>".$URL['host']."</b> visitor!";
}
?>
