My Website has only one product of each kind so I have set Product Sold Individually to Yes and Stock Quantity to 1
When someone adds the product to cart for the first time it gets added fine, But Since the product is only 1 in stock and this product is already added so the add to cart button for that product should automatically disappear or gets disabled instead on clicking it for the second time it takes user to the product page and displays a warning message there.
I want to disable product add to cart button when clicked as we have only 1 of that product in stock.
Please help me with this, Thanks
