Quote from Thisishowwedoit: “Hello Simply create a form with an input field named "ik_payment_amount" and send this form to "?page=paypal" Will work with all versions of php and interact with paypal, if paypal doesnt reconigze the payment it will never be processed. No problems with those 2 files. Over and out ” In which folder do I have to load the two files on the server? How do I integrate the payment into the game?
