Redirect to the Right shop after payment - Multistore

[nooiz007]

I have a payment module that use a external webpage for a secure payment, and after the payment the costumer is redirect back to the store.

 

The problem is that I have lots of stores like www.mydomina.com/stores/storeA , www.mydomina.com/stores/storeB, etc.

 

But I can only set one page for the payment to be redirected, so I goes to the main store www.mydomain.com/stores/

 

The redirect.php page code that is redirected is like this:

 

<?php

include_once(dirname(__FILE__).'/../../config/config.inc.php');

 $useSSL = true;

include_once(dirname(__FILE__).'/../../init.php');

$url = Tools::getShopDomain(true,true).__PS_BASE_URI__.'index.phpfc=module&module=cielointegradoloja5&controller=ok';

?>

<script>location.href='<?php echo $url;?>';</script>

 

I am wondering if there is anyway to make it to redirect to the store that the payment came from....
