I'm trying to create a form input field on the products page where the user will enter a customer reference number / unique transaction id that will then generate a product from the catalog.

At the moment I just need to be able to have a form input for them to enter the numbers the actual functionality isn't that important at the moment, but if there is some that would be great.

I also need their email address so I can send them a receipt and invoice, also their name etc...not necessarily their home address unless they specify.

The rest is easy I'm going to be using PaypalWPP for the transaction.

Then send all the data to the organisation that is distributing, verifying the product.

Any help please I've tried many solutions however cannot find a solution easily.
