Cart recap displays "quantity" instead of number of products

Question

With WooCommerce and a Storefront Child Theme, in the checkout page, the cart recap displays "quantity" instead of the actual number of products.

If I add <?php echo $cart_item['quantity'] ?> to the code, it displays the correct quantity value. Maybe it's the filter that is wrong?

review-order.php (using Yith-Multi-step-checkout plugin):

<?php
/**
 * Review order table
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/checkout/review-order.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see https://docs.woocommerce.com/document/template-structure/
 * @package WooCommerce/Templates
 * @version 3.8.0

Edit

Also I just discovered that ticking/unticking the "ship to a different address" box, multiplies the 'QUANTITY' text!

Answer 1

I suggest that yout replace sprintf( '× %s', $cart_item['quantity'] with sprintf( '× %u', $cart_item['quantity']. Note %s → %u. There is no point in formatting an integer as a string.
