OpenCart: Adding payment specific order total

I'm developing a custom payment module for OpenCart. For this, i want a specific order total, but i'm unsure how to make a order total count only for this payment option.

So far i've laid out the basic file structures for a payment module, and i can choose it on checkout. I have also added my own order total to catalog/model/total

I'm guessing that i need some logic in the getMethod of catalog/model/payment/my_payment_module

Can anyone point me in the right direction?

Solution

  • I ended up solving this myself.

    I added a new Order Total class. Inside it i checked for the correct payment method in the session before returning anything.

    All the totals will update when the payment method is changed, so this works fine.
