Coupon required to proceed with the purchase

Hello,

AwoCoupon Pro: 2.1.7
Joomla: 2.5.9
Virtuemart: 2.0.18a

Can I configure the component in such a way that the inclusion of the coupon is mandatory to proceed with the purchase?
In practice, I wanted to know if it is possible that a user purchases only if he is in possession of a coupon code.

Thank you.

Paolo

Hello,

You cannot do that through AwoCoupon, but you can probably do that by hacking the core code of virtuemart.

I would start by looking at
www/components/com_virtuemart/helpers/cart.php, there should be a confirm function, which you can check if a coupon code exists and if not, do not confirm the order.
