I have a question!
How can I add to cart and make payment with PHP?
For example, I downloaded this page https://codyhouse.co/gem/product-builder/ , but at the last step I'm not able to make the "buy now" action.
Where can I find a tutorial or a download to modify ad apply to this?
Because I do not know how to send the product to the Cart with the latest user-specific choices.
Thanks!
