Can you share the PHP code you are using? It may need to be used outside a loop.
I am essentially looking for an item counter to determine whether I need to show the cart or not.
Thanks
[EDIT: 08/01/2013]
I managed to get this to work for myself. I have it in my theme’s sidebar.php
file
<?php
if (!dynamic_sidebar( 'sidebar-cart' )) {
$args = array( 'post_type' => 'product' );
$cart_quantity = sprintf(_n('%d', '%d', jigoshop_cart::$cart_contents_count), jigoshop_cart::$cart_contents_count);
if ( $cart_quantity > 0 ) sidebar_cart($args);
}
?>
