Need to put code on the Thank-you page

-- HikaShop version -- : latest (Starter)
-- Joomla version -- : 3.2.1
-- PHP version -- : 5.3.28

Hi there,

I need help again. I need to put a tracking-code on the last checkout-page, after a sale is complete. This thread didn't work.

What I have done already:
- I have put my code in the checkout/end.php --> no success
- I've put it in /administrator/components/com_hikashop/extensions/plg_hikashoppayment_banktransferbanktransfer_end.php --> no success

This is the code in the end.php, which I've modified:

<?php
/**
 * @package	HikaShop for Joomla!
 * @version	2.2.3
 * @author	hikashop.com
 * @copyright	(C) 2010-2013 HIKARI SOFTWARE. All rights reserved.
 * @license	GNU/GPLv3 http://www.gnu.org/licenses/gpl-3.0.html
 */
defined('_JEXEC') or die('Restricted access');
?><?php
if(empty($this->html)){
	echo JText::_('THANK_YOU_FOR_PURCHASE');
}else{
	echo $this->html;
}
<?php 

   $ad_ordernumber = $this->order_number;
   $ad_net_amount_step = $this->amount;
   $ad_net_amount = round($ad_net_amount/1.19);
echo 'Hello Test-World. Say something!!</br>';
echo $ad_net_amount;
?>
<!-- Trackingcode -->
<script type="text/javascript" src="//www.xxxxxxx.com/js/jsadlib.js"></script>
<script type="text/javascript">
Aff.user.track({
    'eventid' : 12345,
    'referenz' : '<?php echo $ad_ordernumber; ?>',
    'betrag' : <?php echo $ad_net_amount; ?>,
    
    'pid' : 12345
});
</script>
<noscript>
    <img src="//www.xxxxxxx.com/event.php?pid=12345&eventid=4454&referenz=<?php echo $ad_ordernumber; ?>&betrag=<?php echo $ad_net_amount; ?>" border="0" width="1" height="1">
</noscript>

$this->nextButton = false;

It's me again...

Okay I got it. It's the checkout/end.php file and modifications are only visible when editing via views -> display -> end.php

But my code causes errors. I need the order-number and the net-amount as a variable. As I wrote, I tried to fetch the values like this:

$ad_ordernumber = $this->order_number;
$ad_net_amount_step = $this->amount;

This does not work. Anybody knows, how to catch the order-number and the net-amount?

Now I tried this (end.php):

$orderClass = hikashop::get('class.order');
$order = $orderClass->loadFullOrder($order_id);
echo 'Total:</br>';
echo $order->full_total->prices[0]->price_value_with_tax;
echo 'Order number:</br>';
echo $order->order_number;

What's wrong here?

Nicolas, thanks a lot! That's it.

Just to understand, I need to initiate the classes via the function JRequest::getInt() and JFactory::getApplication()?!

Well, however, everything works fine now, an I'll switch over from "play mode" to serious business. After setting up the shop and creating all the products, I'll upgrade to business version. Your support is great, so I feel comfortable here, just for the event something's crashing!!

Thanks and have a nice weekend
