Get quantity of a specific product from the cart

Hi Ray!

I would like to query the cart to get the quantity of a specific product that is in it.

This is so that I can stop people adding more items to the cart, than is in stock.

For example, when a product page is loaded I will get the quantity of the cart contents for that item (if it exists) and subtract from the stock in the database, giving the available stock to the that customer at the time.

Could you point me in the right direction as to how I might do this?

Cheers
Ian

Are you trying to get the total quantity for any shoppers, or just the current customer's quantity? To get the current customers quantity you can use:

$eCart1->GetInfo("ID","Quantity");

Thanks Ray, just the current shoppers.

I know to do all that the cart would need to be stored server side and there isn't the budget for that.

Cheers
Ian
