function uc_cart_get_total_qty in Ubercart 7.3

Same name and namespace in other branches

1. 6.2 uc_cart/uc_cart.module \uc_cart_get_total_qty()

Returns the total number of items in the shopping cart.

The total number of items in the cart isn't simply queried directly from the database, because when the shopping cart is loaded items may in fact be altered or removed. Hence we actually load the cart and tally up the total number of items from the fully loaded cart instead.

Parameters

$cid: The cart ID of the shopping cart whose items we're totalling; defaults to the current user's cart.

Return value

int An integer representing the total number of items in the cart.
