WooCommerce: Add a Third Description @ Single Product Page

There are times when the “long description” and the “short description” are not enough on the WooCommerce Single Product page. What if you need to add another HTML content section – say – at the very bottom of the page (and maybe, because of the longer page, add another add to cart button there as well)?

In this simple snippet, we will add another “WYSIWYG” text editor in the Edit Product page, and display the output at the bottom of the single product page. Enjoy!

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
