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!

Here’s an additional piece of content I was able to add to the bottom of the single product page thanks to the snippet below.
And this is the backend – a new meta box on the Edit Product page where you can enter HTML content

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

  1. How can I make it work with a custom single product elementor template?

    1. No idea, I don’t use Elementor unfortunately

      1. I use shortcode

        add_shortcode( 'thirddescpdp', 'your_theme_slug_name_shortcode' );
        function your_theme_slug_name_shortcode() {
        	   global $product;
           $third_desc = get_post_meta( $product-&gt;get_id(), '_third_desc', true ) ? get_post_meta( $product-&gt;get_id(), '_third_desc', true ) : '';
           if ( ! $third_desc ) return;
           echo '';
           echo $third_desc;
           echo '';
