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!

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.

	return $found;
}

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
