In order to integrate WHMCS 4.x with Jrox Affiliate Management (JAM) system , create a file named jam.php in whmcs/includes/hooks with following content :
<?
function actionhook_InvoicePaid($vars) {
if (!empty($_COOKIE['jrox'])){
$result=mysql_query("SELECT * FROM tblorders WHERE invoiceid = '".$vars."' LIMIT 1");
$row = mysql_fetch_array($result);
$JAMIntegrate = file_get_contents("http://www.domain.com/affiliates/sale.php?amount=".$row['amount']."&trans_id=".$vars."&custom_mid=".$_COOKIE['jrox']);
}
}
add_hook("InvoicePaid",0,"actionhook_InvoicePaid","");
?>
Make sure to point www.domain.com/affiliates to your JAM installation URL.
