Does anyone know how to enforce a minimum order quantity by role? My wholesale customers must have an order quantity of 12.
There is a module that does this at http://drupal.org/project/uc_moq . However, the documentation doesn't mention anything role-based, and it has not been updated for Ubercart 3.
The rules system can set up conditions for "customer has role" and "order quantity numeric comparison". It has actions for "print error message" and "redirect page". However, there is no "customer starts checkout" trigger to do the check at the appropriate time.
Anyone know how to do this?
