Option and notes fields after cart at checkout for order, not just line items

Question

My client has gift wrapping services but they apply to the entire order, not one single line item.

How would I add notes or custom fields to the entire order, at the shipping stage of checkout? is this possible without a plugin?

I tried to apply notes and giftwrapping options to the first line item by using the commerce/cart/updateLineItem form, on the cart.lineItems.first() but it didn't work. I presume that after the user proceeds to checkout the line Items no longer exist?

Answer 1

You could create a special product for the gift wrapping and offer to add it to the cart during the checkout process with a separate updateCart form.

As for the notes, you can add a custom field to your order as described in the following: How can I update custom order fields in the frontend

Answer 2

First, add a custom field to your orders, let's call it orderNotes.

Then, in any updateCart form, you can use an input with name="fields[orderNotes]" to set the value of that field.

(Line items persist on the cart until the end of checkout. At that point they become a saved snapshot of those line items on the completed order.)

<form method="POST" >
       {{ getCsrfInput() }}
       <input type="hidden" name="action" value="commerce/cart/updateCart">
       <input type="text" name="fields[orderNotes]">
       ...etc

Answer 3

You can also add it to the cart.lineItems[].options:

<form method="POST" >
    {{ getCsrfInput() }}
    <input type="hidden" name="action" value="commerce/cart/updateCart">
    <input type="hidden" name="purchasables[{{ purchasable.id }}][id]" value="{{ purchasable.id }}">
    <input type="number" name="purchasables[{{ purchasable.id }}][qty]">

    // custom option
    <input name="purchasables[{{ purchasable.id }}][options][giftWrapping]" value="YES!">

</form>
