I've got a setup where the user when buying a product submits their details via a gravity form using the woocomerce add-on, and then is redirected to the checkout for payment.
Everything works, I receive the filled out form and the user can purchase the product. It's just there's nothing in the form to connect it to that specific order. So when it's payed for via paypal unless their paypal email matches their email in the submitted form I have no idea who's paid for what.
I'm guessing there must be some built in way of providing this information in the form, but I can't for the life of me find it.
