WooCommerce: Exclude Product From Discount Coupons

WooCommerce coupon settings allow you to define allowed products (or product categories). What’s missing, however, is the other way around: how to set up a product so that it can never be discounted?

Thankfully, a handy WooCommerce filter comes to the rescue (“woocommerce_coupon_is_valid_for_product“) and we can therefore make all coupons “invalid” when a given product is in the cart. Enjoy!

Here’s what happens

PHP Snippet: Disable All Coupons for a Single Product ID @ WooCommerce Cart / Checkout Page

add_filter( 'woocommerce_coupon_is_valid_for_product', 'bbloomer_exclude_product_from_product_promotions_frontend', 9999, 4 );

function bbloomer_exclude_product_from_product_promotions_frontend( $valid, $product, $coupon, $values ) {
   // PRODUCT ID HERE (E.G. 12345)
	if ( 12345 == $product->get_id() ) {
		$valid = false;
	}
	return $valid;
}

Where to add this snippet?

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

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 7.3.

  1. Hey!

    Can this be used for a whole category? If so, are you able to provide the edit for this? (Apologies for the noob question!)

    Thanks

    1. Hi Hassan thanks so much for your comment! Yes, this is definitely possible, but I’m afraid it’s custom work. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding!

  2. Hi,
    This code didn’t work.
    Woocommerce version: 4.5.3
    Php version: 7.4.24

    Any changes to make ?

    1. Hi Sai, did you test with a different theme and no other plugins but Woo?

      1. Isn’t working.

        After implementing the code, no coupon is accepted.
        Even if the product in question is not in the shopping cart.

        The version shown above and my version ALWAYS indicate that no voucher can be accepted.

        I suspect the filter has changed.

        add_filter('woocommerce_coupon_is_valid_for_product',    'exclude_product_from_product_frontend', 5,    4);
        function exclude_product_from_coupon_frontend($valid, $product, $coupon, $values)
        {
            // $valid = true;
            // array der Gutschein ID's
            $gutschein_ids = array(
                20870,
                20869,
                20859,
                20840
        
        
            );
            // PRODUCT ID HERE (E.G. 12345)
        
            // if (in_array($product->get_id(), $gutschein_ids)) :
            if (20870 == $product->get_id()) :
                $valid = false;
            endif;
        
            return $valid;
        }
        1. Works for me. Before testing, did you completely empty the cart and cleared customer sessions? Let me know

  3. Hi Rodolfo
    Super snippet – Always had to remember to exclude some speciel products -So this is very helpfull Thx
    What if I have 3 products that I always want to exclude? Can you show how? is it “just” id seperated with komma, or do I need an array?

    Happy Easter and posting

    Peter

    1. Cool. You should use the in_array() PHP function
