Updating cart item to quantity 0 not working?

[yinny]

In the shopping cart view (shopping_cart.php), if I put a quantity of 0 and click update I want to have the product removed from the cart. Instead, the value is set back to what it was previously. Any other number entered for the quantity works fine, just not 0.

 

Some customers don't see the remove checkbox and get frustrated that they cant' figure out how to remove items from the cart since it won't take a 0.

 

Can someone point me in the right direction??? thanks.

found it..........

 

edit catalog/includes/classesshopping_cart.php and add this line..........

 

if ($quantity==0) $this->remove($products_id);

 

before this line..........

 

if (empty($quantity)) return true; // nothing needs to be updated if theres no quantity, so we return true..
