general payment module cancel URL

[BoKr]

Hello

 

I want to change the cancel URL of at least one of my payment modules. I understand that if this is not 'hardcoded' in an iframe being loaded via the payment module (PSP) than I could change it of course in the TPLs themselves.

 

I tried to add a variable and then to redirect the cancel URL via this variable. Sorry, if there is a possibility I am talking ... but it is my first time I am trying to do a thing like this (and I have no basic knowledge of smarty and module developing:):

 

submit.php

 //URL's
 $backtomy_payment_methods_url = Tools::redirect('index.php?controller=order&multi-shipping=');

//API ^^
 $api->UrlRedirectCancel = $ito_payment_methods_url;

Well, I think this should would if I'd know how to write the URL of the payment overview tpl. I hoped

• order&multi-shipping
• order&multi-shipping=

should do the trick.

 

Can someone please give me a tip if possible?
