WooCommerce: show checkout error if weight exceeds a threshold
A WooCommerce fan asked me: “How do you deny checkout if the cart weight is above a certain threshold?“.
Well, this is straight forward thanks to a WooCommerce core function called “cart_contents_weight” which allows you to get the total weight of your cart, and then the “wc_add_notice” function which shows a notification error.
Enjoy!
