I need a simple script for people to pay their bill with a MIGS/ANZ gateway.
The site will run in WordPress. I need to be able to have a page that let's people enter the invoice number (not required for them), their billing info, and it should process the card, and then give them a screen showing it paid and allow them to print the receipt. It should also send an email to the site owner as well as the customer. There should be a place in the backend "MIGS Bill Pay Settings" that let's me set the merchant id, etc.
