I have a Wordpress and WooCommerce site for a client, and to create a little twist on the customizing on a product I have a external html-page opening in a FancyBox iFrame using Easy FancyBox plugin (http://wordpress.org/plugins/easy-fancybox/).
Now when the user is done with the form inside that iframe, which sends data using GET to the checkout form, I want the FancyBox to close and move the user to the cart/checkout page.
At least close the box and reload the page so that I can show the user a message that the product was added.
How would I do that? I'm rather new to this kind of stuff.
