Add this code to your child theme’s functions.php file or via a plugin that allows custom functions to be added, such as the Code snippets plugin. Avoid adding custom code directly to your parent theme’s functions.php file, as this will be wiped entirely when you update the theme.

To display the cart contents and total in your template, use something like:

// Use in conjunction with https://gist.github.com/woogists/c0a86397015b88f4ca722782a724ff6c

<a class="cart-customlocation" href="<?php echo wc_get_cart_url(); ?>" title="<?php _e( 'View your shopping cart' ); ?>"><?php echo sprintf ( _n( '%d item', '%d items', WC()->cart->get_cart_contents_count() ), WC()->cart->get_cart_contents_count() ); ?> – <?php echo WC()->cart->get_cart_total(); ?></a>

To ajaxify your cart viewer so it updates when an item is added (via ajax) use:

/**
 * Show cart contents / total Ajax
 */
add_filter( 'woocommerce_add_to_cart_fragments', 'woocommerce_header_add_to_cart_fragment' );

function woocommerce_header_add_to_cart_fragment( $fragments ) {
	global $woocommerce;

	ob_start();

	?>
	<?php
	$fragments['a.cart-customlocation'] = ob_get_clean();
	return $fragments;
}
