I'm building a website for a wholesale business that is selling plants. They want to provide their customers an option on the cart page to add labels to the plants. Therefore I want to add a custom input field per product in the cart where customers can type in the amount of plants they need. When the update cart button is clicked I want the amount of labels to be added to the cart item data.
I found that I can use woocommerce_add_cart_item_data hook this way:
add_filter( 'woocommerce_add_cart_item_data', 'add_labels', 10, 3 );
function add_labels( $cart_item_data, $product_id, $variation_id ) {
$cart_item_data['amount_of_labels'] = 200;
return $cart_item_data;
}
And when a product is added to the cart, a value of 200 is stored for the key 'amount_of_labels' in the product cart item data. This value is retrievable on the cart and checkout page and can be store in the order item meta data.
My question is:
Is there a same sort of hook/action available for updating cart data on the cart page itself?
I see that there is woocommerce_after_cart_item_quantity_update hook. But it is not working properly for my case. With that hook I can't update my custom cart item data (adding updating or removing).
Example screenshot:
Here you can see what I am trying to build. The inputs in the screenshot take the amount of labels and those should be added to the cart item data when updating the cart.
