WooCommerce: Disable “You cannot add another __ to your cart” Message

When a WooCommerce product is set to “Sold Individually”, you can only add 1 item to the cart. If you try a second time, you will get the “You cannot add another “%s” to your cart” error message, so that the customer is aware that there is already that product in the cart.

However, you may want to either edit the message wording or completely remove it, especially if you automatically redirect to cart or checkout upon add to cart.

So, let’s study how to do the latter, which is much more complex than using the ‘woocommerce_cart_product_cannot_add_another_message‘ filter for editing the message content. Enjoy!

This online course is set to “Sold Individually” because I want customers to add only 1 to cart in a single order. If you try to add to cart a second time, the “You cannot add another __ to your cart” error message appears. Let’s get rid of that!

PHP Snippet: Hide “You cannot add another product to your cart” Message @ WooCommerce Single Product / Cart Page

Unfortunately there is no way to just erase the message, so we need a workaround. And this requires adding an “Exception” so that the item is not added to the cart and no message is therefore returned.

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101

  1. Hi ­čÖé I would like to change the content of this alert, but my code does not work.

    add_filter( 'woocommerce_cart_product_cannot_add_another_message', 'woocommerce_cart_page_message_callback_change' );  
    function woocommerce_cart_page_message_callback_change() {
        return __( 'Nie mo┼╝esz doda─ç produktu — do koszyka, poniewa┼╝ produktu nie ma w magazynie. Wybierz inny kolor', 'text-domain' );
    }
    
    1. Hello Aga, what error do you get? Or what does the message say?

  2. Hi this code doesn’t work. Can you revise it?

    1. Thanks for your feedback, but it works for me. Can you test it again with no other plugin other than Woo and the Storefront theme please?
