WooCommerce: Retain Field Values @ Checkout Reload

Go to WooCommerce Checkout as a logged out user. Fill out billing name, surname, address, email and phone. Change your mind and go back to Cart. Return to Checkout. Billing name, surname, email and phone (basically everything but the address) are gone!

But hey, this annoying WooCommerce flaw is about to go away with a few lines of code. Either reload the Checkout page or go back to it later – your info will still be there (as long as you haven’t cleared your cache/cookies and the WooCommerce session hasn’t expired of course).

Enhoy!

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101
