How can I pass a node's nid variable to Ubercart so that when the user pays for publishing his node, the nid shows in the cart?
I tried to add a field to the Ubercart Order fields, with widget node reference which is passed by the URL. When my user clicks on "Pay for node" link, it sends him to the Ubercart "node" product page "pay?23" 23 being the node they are paying for. When the user presses Add to Cart, I cannot see this value 23 in any of the user's order or checkout details. How can I get this value attached to the order?
I've googled for a while now and cannot find anything about this for D7. Any help will be much appreciated!
