woocommerce_add_to_cart_validation │ хук-фильтр │ WC 1.0

Filters if an item being added to the cart passed validation checks.

Allow 3rd parties to validate if an item can be added to the cart. This is a legacy hook from Woo core. This filter will be deprecated because it encourages usage of wc_add_notice. For the API we need to capture notices and convert to exceptions instead.
