Offline Credit Card

I'm using the offline credit card payment method and I was wondering how I can make the card expiry date a compulsory field?

Hi,

That's a good idea to add by default. I've made a patch to add that check, as it's quite easy to do.
Download again the install package of HikaShop on our website and install it on yours and you'll get the patch for it.

Thanks Nicolas. This is why I tell everyone Hikashop is the best ecommerce extension. Product + support.
