Empty Cart When Adding A Specific Product

[drchad]

Hi There,

 

I was wondering if there was a way to display a message and empty the shopping cart when someone is trying to add a specific product?

 

I have membership services that need to be processed with a recurring payment, so they use a specific payment module, while everything else is just a one-time purchase that goes through another payment module.  Therefore if someone wants to buy a membership service I want this to be the only item in the cart.  Ideally if they had other products in the cart and tried to add the membership service it would pop up a message saying that this product can only be purchased alone and then clear the cart if they accept.  

 

Does anyone know if this is possible?

 

Thanks

Hi

 

It is possible for sure, you can make an override of the CartController to do this.

 

A module will be fine to choose wich 'product' is the subscription.
