SteamID => Steam Community URL

[dezkit]

I have this function written in php that changes a designated steamid to their assigned Steam CommunityURL.

PHP Code:

<?php
function getFriendId($steamId)
{
    $gameType = 0;
    $authServer = 0;
    $clientId = '';
    $steamId = str_replace('STEAM_', '' ,$steamId);
    $parts = explode(':', $steamId);
    $gameType = $parts[0];
    $authServer = $parts[1];
    $clientId = $parts[2];
    $result = bcadd((bcadd('76561197960265728', $authServer)), (bcmul($clientId, '2')));
    return $result;
}
?>

So I have a user profile field assigned to SteamID, people can put their steamid, and etc.

Now is this possible to put this on postbit_legacy so that it converts the steamid into the community url and echo it in the menu of when you click on a persons username?

This is what I have so far, which is for the SteamID.

PHP Code:

<if condition="$post['field7']">
      <tr><td class="vbmenu_option"><a href="http://steamid.esportsea.com/?action=search&type=single&key=steam_id&query=$post[field7]">SteamID: $post[field7]</a></div></if></td></tr> 


What I want but don't know how to do: Grab field7, convert it into the steam community url, and echo it in a new vbmenu option

I hope somebody can help me out. Thank you very much.
