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 custom code?

You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its 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 guide "Should I Add Custom Code Via WP Editor, FTP or Code Snippets?" and my video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything went 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.

    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

      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!

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

        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;
}

          Works for me. Before testing, did you completely empty the cart and cleared customer sessions? Let me know

      Cool. You should use the in_array() PHP function
