I have a client who has a web hosting setup with os commerce 2.2. They have a custom field populated for a field per product. This would be a charge that is unique per product. A core charge.
They are using authorize.net for billing.
I would like to add this charge to the final payment processing. Where does this occur?
in includes/modules/payment.php? checkout_process.php? or authorizenet_cc_aim.php in the payment include directory?
What code should I change?I can get the values based on a product and its quantity.... can add it to order totals table.....
