I need to allow users to upload their own files during a checkout process.
I think Freform Pro should be fine but I don't know how to integrate it inside the checkout page. Should be nice to associate this file as custom order field for Expresso Store.
my goal is to handle the upload process in ajax and render the uploaded image file in the same page.. the scenario should be something similar to:
User chose the t-shirt model and size > add to cart > upload own image > preview the image stamp on the t-shirt > purchase it!.
someone have any idea?
