Linkable Custom Profile Fields

[GameWizard]

I have a custom profile field appearing in a custom template as $userinfo[field32], I want the output to be linkable. However the content is a list of items seperated by commas.

Basically I am looking to do something similar to this hack here, but for VBulletin 3.7 and applied to a custom template with custom profile fields:

So i'd like each item seperately linkable to the memberlist search. Here is the code I have which doesn't seem to be working:

if ($userinfo['field32'] != '')  
{ 
        $links = explode ("\n", $userinfo['field32']); 
        $output = array(); 
        foreach ($links as $link) 
        { 
                  $link = trim($link); 
                  if (!empty($link)) 
                  { 
                            $ouput[] = '<a href="' . $link . '">' . $link . '</a>'; 
                  } 
        } 
        $userinfo['field32'] = implode('<br />', $output); 
}

Also, if made functional. How would I make it work for more than 1 profile field? An Array I presume?
