HOW TO: show number of products in cart

Shwoing the number of products in osCommerce cart is very simple;

echo $cart->count_contents();

This will show the total number of items in a persons cart.

You can go further with this and say something like;

You have <?php echo $cart->count_contents(); ?> items in your cart.

But this will not be grammatically correct if only 1 item is in the cart, In this case we say;

You have <?php echo $cart->count_contents(); ?> <?php echo $cart->count_contents() == “1” ? “item ” : “items ” ; ?> in your cart.

Now the code will determine whether to say “item” or “items” depending upon the number of items in the cart.
