I want to limit the quantity of items per SKU

e.g A user clicks on a product twice, and the cart only accepts 1 not 2 of the same product.

I want to limit users but querying the cart to see if the cart os holding a sku the turn the 'add item' button for that specific product off or disable it.

thanks

after clicking on the add to cart button using javascript add the disable attribute to it

In the first instance javascript offers a solution that works well for double click, but I am looking for a more logic based approach that looks at the items in the basket, then disables the button of the relevant products.

If I used javascript alone the buttons would be re-enabled on refresh or page load.

Thanks for the suggestion.
