How to restrict to just one product in the cart per customer?

[gifro10]

I know this is against the main purpose of a "cart," but I would like to restrict the ability of a user to add more than 1 product to their cart.

With my store, although they choose from a few products, each customer will only ever buy 1 product at a time, so I want to make sure they aren't able to add more than one to their cart to avoid problems.

I've figured out how to set a maximum quantity, which restricts users from adding more than one OF THE SAME product, but they can still add multiple different products.

A long story short... how to only ever allow ONLY ONE product in the cart? Right now I have 4 total products all in the same category if that helps.

Thanks

There is a Minimum Order add-on that could probably be adapted to manage Maximum Order ...

Peek in the Downloads and see if this is something you might be able to tackle on your own ...

Got your coder hat on tight?

Sounds rugged but I'll give it a try... I'm not much of a coder but more of a "delete-that-section-of-code-when-someone-says-that-will work" type of guy

I'll take a peek
