Converting username text to url

[Dismounted]

There are a couple of other threads talking about implementing BB codes via PHP - I have previously posted in them with examples.

Dismounted I saw some of your post like you said including this
Anyway this is what I have so far.

Dropped into "bbcode_create"

PHP Code:

require_once(DIR . '/includes/bbcode_user.php'); 


Dropped into "bbcode_fetch_tags"

PHP Code:

$tag_list['no_option'][user] = array(
                                    'callback' => 'handle_external',
                                    'strip_empty' => true, 
                                    'external_callback' => 'bbcode_user'
                                    ); 


and this is the php file

EDIT*****

PHP Code:

<?php
require_once('./global.php');
require_once(DIR . '/includes/class_bbcode.php');
require_once(DIR . '/includes/functions_user.php');
function bbcode_user(&$parser, $value) 
{
    $fetchuser = $db->query('
        SELECT displaygroupid, username, userid
        FROM ' . TABLE_PREFIX . 'user
        WHERE username = '$value'
    ');
    
    if ($user = $db->fetch_array($fetchuser))
    {
        fetch_musername($user);
        $name = '<a href="member.php?' . $vbulletin->session->vars['sessionurl'] . "u=$user[userid]\">$user[musername]</a>";
        return $name;
    }
}  
?>

I am getting error when I click "BB code Manager"

Fatal error: Call to a member function clean_array_gpc() on a non-object in *****\www\Forums\global.php on line 22

and I get this when I use the bbcode in a post:
EDIT**********

Parse error: parse error, unexpected T_VARIABLE in ****\www\Forums\includes\bbcode_user.php on line 10

Any help would be awesome!

Remember that you are in function scope, and therefore, variables such as $vbulletin and $db will not exist - unless allowed to exist through the global keyword. Also, you may want to use query_first(), which will automatically fetch the first result and place it is an associative array.
