Product Total Quantity

If customers add quite a lot products to cart, when they view the cart, they are difficult to find out total how many they added to cart.

Or, if there is a situation: Purchase any product, get 20% discount if more than 100 pieces. Customers need to know how many they have added to cart.

Here is the coding to show total how many products added to cart:

<?php global $woocommerce; ?>
<?php echo sprintf(_n('%d', '%d', $woocommerce->cart->cart_contents_count, 'woothemes'), $woocommerce->cart->cart_contents_count);?>

I added the coding before Cart Subtotal, you may add to any place you want.

<tr class="cart-subtotal">
	<th><?php _e( 'Product Quantity', 'woocommerce' ); ?></th>
	<td><?php global $woocommerce; ?><?php echo sprintf(_n('%d', '%d', $woocommerce->cart->cart_contents_count, 'woothemes'), $woocommerce->cart->cart_contents_count);?></td>
</tr>
