WooCommerce: Slashed Cart Subtotal if Coupon @ Cart

This is a nice snippet to let users know what the original cart amount was by slashing the price and showing the price after the discount on the same line (subtotal). You can then hide the coupon code line if you wish ๐Ÿ™‚

PHP Snippet: show slashed original and discounted subtotal @ WooCommerce Cart

add_filter( 'woocommerce_cart_subtotal', 'bbloomer_slash_cart_subtotal_if_discount', 99, 3 );

function bbloomer_slash_cart_subtotal_if_discount( $cart_subtotal, $compound, $obj ){
global $woocommerce;
if ( $woocommerce->cart->get_cart_discount_total() <> 0 ) {
$new_cart_subtotal = wc_price( WC()->cart->subtotal - $woocommerce->cart->get_cart_discount_tax_total() - $woocommerce->cart->get_cart_discount_total() );
$cart_subtotal = sprintf( '<del>%s</del> <b>%s</b>', $cart_subtotal , $new_cart_subtotal );
}
return $cart_subtotal;
}

Where to add this code?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such delicate files - if you need more guidance, please take a look at my free WooCommerce Customization video tutorial.

Does this snippet still work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.

  1. Hi rodolfo,

    Thank you for this snippet to display cart sub total at front end, Is there any way to do same at backend. When someone applied a coupon to order. its not displaying sub total. only displaying discount amount, tax and total amount after discount.

    Discount: $12.00
    Shipping: $0.00
    Order total: $12.00

    1. Hey Sunny, thanks for your comment! Yes, I’m sure this is possible. The function would be similar but you need to find the “hook” that corresponds to the order total in the admin ๐Ÿ™‚
