How to use the Rules module to attribute a new user role after a product was bought?

Question

I use these modules: Drupal Commerce, Rules, Node option premium.

My question: with Rules, how attribute a new user role, when the product was bought, and when this product is a premium content ? So that, when a user bought the product, that user can have access to full content.

Answer 1

Refer to the tutorial Selling Content with Drupal Commerce using Content Access and Roles for granting access to premium content to users who have a "premium" role.

Here is a summary of the steps required (= quote from that link):

• Enable Content Access and the ACL (optional) module.
• Create a role called "premium".
• Create a content type called "Premium Content" and put some great content in it.
• Verify that users can only access the premium content if they have the premium role.
• Create a product representing the premium role.
• Create a rule that grants the premium role on order completion:
  • After updating an order.
  • If the order state is Completed.
  • And the order contains our premium product.
  • Add a role to the user who is the owner of the order.
