The fields are required however you could hide them via CSS and fill the values with your own email address. The gift card would not be delivered to the recipient, instead it would be sent to whatever email address you place in the “To” field. You will have to figure out how to get the gift card to the recipient. Since you aren’t asking for this information from the purchasing customer you will have to reach out to them some other way.
If you still want to go this route, you can 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
Once the file is in your theme folder, open it up in a text editor and make any changes.
I’m closing this thread, just let us know if you need anything else though.
