The “To” field is required since that is where the gift card will be emailed. With that being said, you could do some custom programming to fill in the To field with the purchasing customer’s email address.
Note that if the customer is not logged in then you will not have an email address and that might be a problem since it is required.
We use the built in WooCommerce template system so that you can fully customize these fields.
To override the HTML for these fields, copy this file:
/wp-content/plugins/pw-woocommerce-gift-cards/templates/woocommerce/single-product/add-to-cart/pw-gift-card-before-add-to-cart-quantity.php
To here (create any missing subfolders):
/wp-content/themes/<your_theme>/woocommerce/single-product/add-to-cart/pw-gift-card-before-add-to-cart-quantity.php
This is a custom programming task so relay this information to your programmer.
