Payment Processing Error When Gift Certificate is Greater Than Cart Total

Hey everybody,

I have recently purchased AwoCoupon and cannot say enough about how great this component is. Seyi has done a wonderful job and his level of support is great.

I have come across one error that I cannot seem to fix... I have exhausted all my resources and am desperate for a fix.

Here is the deal: We have created two gift certificates ($25 and $50) and purchasing them works like a charm... the email with certificate is mailed without any issue. However, THE ISSUE IS when we try to redeem the gift certificate for a product that is less than the value of the gift certificate, it will not process. The shopping cart shows a total price of $0.00 so the payment process is getting confused (I assume).

It seems like there should be a fix for this. I am no PHP expert, but it seems like the logic would be as follows: IF coupon code is used AND shopping cart total equals $0.00 THEN bypass the payment processor and just accept the transaction.

Any help would be much appreciated.

Thanks,
Adam

Ah yes, the payment processor should be totally bypassed if the order total is 0. I found that there is sometimes a rounding issue that causes it not to be bypassed, here is the fix:

hope that works
