My boss wants me to add a number of items to the cart based on a user
form input. At the moment my add to cart function checks if anything is
in it and then increments one item (using this code). I can supply the
full function if required but just this part would get me away I think.
if($cart[$new])
$cart[$new]++;
Instead of incrementing by one how do I increment by a variable which
would be the form input?
