Hi,
Okay, so you need to override the collect on delivery "end" view.
In that view there is no access to the order object ; but if you perform a little modification in the plugin (that I will add in HikaShop 3 too), you will gain that access.
In the plugin you need to replace :
$this->order_number = $order->order_number;
$this->showPage('end');
By
$this->order_number = $order->order_number;
$this->order = $order;
$this->showPage('end');
And then, for the override of the view "collectondelivery_end.php", you have copy the plugin file into :
/templates/YOUR_TEMPLATE/hikashoppayment/collectondelivery_end.php
Regards,
