WooCommerce: “Is This a Gift?” Checkbox @ Single Product Page

A client of mine asked me to code a checkbox on the single product page called “Is this a gift?”. They noticed that their customers who want to gift the product to a friend get confused with the “Shipping to a different address” form in the WooCommerce checkout.

So, what about renaming “Shipping to a different address” into “Who is this gift for?” if a “gift” is in the cart? Well, this snippet does just that and you can adapt it / customize it to your specific case.
