Linkable Custom Profile Fields

[GameWizard]

What I've found is that the code works great for any Single-Line and Multi-Line text box. However, I've had trouble converting the code for Multiple/Single menu. It keeps outputting errors which either means that the code is wrong, or the way I'm converting it is incorrect. In any case, I will post the code below in case someone with a more skilled php brain is willing to help:

Here is my functional code once again which applies to Single-Line and Multi-Line text box:

if ($userinfo[field12] != '')
{
        $links = explode (",", $userinfo[field12]);
        $output = array();
        foreach ($links as $link)
        {
                  $link = trim($link);
                  if (!empty($link))
                  {
                            $output[] = '<a href="' .$vbulletin->options['bburl']. '/memberlist.php?' .$vbulletin->session->vars['sessionurl']. 'do=getall&amp;field12=' .trim($link). '">' . $link . '</a>';
                  }
        } 
        $userinfo[field12] = implode(', ', $output);
}

Here is the code included that I need converted into a similar format as above:

            $data = unserialize($profilefield['data']);
            $fieldvalues = explode(",", $profilefield['value']);
            $profilefield['value'] = '';

            foreach ($data as $key => $value)
            {
                $key++;
                foreach ($fieldvalues as $key2 => $value2)
                {
                    if (trim($value) == trim($value2))
                    {
                        $profilefield['value'] .= '<a href="' .$vbulletin->options['bburl']. '/memberlist.php?' .$vbulletin->session->vars['sessionurl']. 'do=getall&amp;field' .$profilefield[profilefieldid]. '=' .$key. '">' .$value2. '</a>, ';
                    }
                }
            }
            
            $profilefield['value']= substr_replace($profilefield['value'],'',-2);
            $userinfo['field' . $profilefield[profilefieldid]] = $profilefield['value'];
