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.

Hello,
Thank you so much for this code.
It works in that the error is not displayed anymore but because the product is already in the cart/basket, I would like to redirect the user to the checkout.
How can your snippet be updated to redirect the user to the checkout?
Thanks
Rob
Rob, 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 🙂 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 możesz dodać produktu — do koszyka, ponieważ produktu nie ma w magazynie. Wybierz inny kolor', 'text-domain' ); }Hello Aga, what error do you get? Or what does the message say?
Hi this code doesn’t work. Can you revise it?
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?
