What is the correct WooCommerce hook to use to modify notices after cart validation is completed and before wc_print_notices() is executed? I’d like to customize the notices based on the totality of the notices to be printed. The woocommerce_add_error filter runs as each individual error message is generated. The wc_get_notices() function returns the notices up to but not including the current notice, and it’s impossible to know which iteration will be the last. I’m using a commercial cart plugin that replaces the woocommerce_before_cart action hook with a plugin_before_cart action hook. When I hook into this action with a priority of 9, wc_notice_count() == 0 and wc_get_notices() returns an empty array. When I hook into this action with a priority of 10, wc_print_notices() has already been executed. What’s the correct hook to use? Also, what is the replacement for the wc_add_notice() function? This comment from the CartController.php file indicates that the use of wc_add_notice() is to be discouraged: * This filter will be deprecated because it encourages usage of wc_add_notice. For the API we need to capture * notices and convert to wp errors instead.
