Additional services for products already purchased
I'm sorry for my English, it's not so trained!
I started using D7 after 2 years of D6 and I'm really enthusiastic.
I'm testing for the first time Drupal Commerce and and I find it truly fabulous!
Now I've got a particular task and I don't know how to proceed.
All the products allow to create nodes of specific content type.
Let's say I've got a free product, then I can buy a premium one which replaces the previous, giving me access to more options. I use node convert to change the content type of the node.
The other case is I purchase an addition service which updates my node (for example, making it sticky at the top of the list).
I can trigger these events with Rules, but I need to display a button for each created node, so the user can choose what type of service purchase for each of them.
How can I go to the checkout, keeping the node's ID until the end so Rules knows which node to apply the change?
Thanx for all answers!
