AffilateLinks On different pages

[hanstavo]

Is it possible to have the affiliate links on different pages  such as the homepage? I tried writing a hook but it is never called the smarty value.

<php
add_hook('ClientAreaHeadOutput', 1, function($vars) {
require_once "includes/affiliatefunctions.php";
include_once "includes/ticketfunctions.php";
$smarty = new Smarty();
$affiliatelinkscode = html_entity_decode($CONFIG['AffiliateLinks']);
$smarty->assign("affiliatelinkscode", $affiliatelinkscode);
});
  ?>
