Drupal Commerce Add To Cart Form Tweaks / Registration Improvements
In this example I’m showing how to improve the Add to Cart button for Drupal Commerce products to show differently based on whether or not users have already purchased a product, or whether the product is already in their cart.
I’m currently working on a site where users are registering for “programs,” which are synonymous with classes, courses, etc. I’m using the following modules (among others) in this example:
- Drupal Commerce
- Commerce Registration
Please understand that when a user registers for a course, they are actually purchasing a product that has a referenced Registration entity.
