I'm trying to create a form for customers to leave their email and get notified when a certain product comes back in stock.
The form sits in a `perch:layout`in `product.html`.
The form collects the emails perfectly well, but I cannot get any product details, or page details to pass into the form.
I would even settle for the URL the form was submitted on, as it would contain the slug.
I've tried several things, including using
similar to passing the product ID to the cart.
Any idea how I can get some page or product info into a form?
