I am trying to create a HTML form so that customers can "Add Funds" to their account. Basically customers can go to "My Account" and from their they will have links to "Add Funds" and "withdraw funds". The Add Funds Page will have selection of payment options like Pay by Credit card using 2CO or some other payment provider. Customer putin the amount to add to their account and I do a POST to the Payment Gateway, Receive the response and process it and update the database.
Question1 - Is their a module available which can do this?
Question2 - Can someone suggest what should be stored in the database when the user hits the submit button and go to the Payment Gateway page. In general need help understanding the different possible scenarios on how to store the transaction information once the user hits the submit button and once when I get a response from the payment gateway.
Question 3 - Does anyone has a sample database schema with the HTML form to do the functionality described above...
I am relatively new to zen-cart and would appreciate your help and patience with my queries....thanks
