Remove "add to cart button" when event date has passed I'm making a webshop that sells tickets for events. And I want that the "Add to cart" button isn't displayed when the event date has passed. But I'm struggling with the Rules module. 

Can someone help me out?
I'm using ubercart
If you're using Drupal Commerce, this question seems to provide a step-by-step of what you're looking for.

How do I use rules scheduler to disable and enable a commerce product entity based on certain date fields?

At the very least it should point you in the right direction and give you a better sense for how Rules integrates with Commerce.
