In this WooCommerce customization, we’re adding input fields to the admin product edit page for a single product and displaying the admin-entered details on the front end of that product page.
For example, suppose you want to highlight product specifications and features for a specific product. In that case, the admin can add these details in the admin panel, and they will appear in the desired spot on the product page (in our case, above the add to cart button). Let’s dive into the implementation steps!

The code snippet will add custom input fields to admin product edit page. These fields values entered by the admin will be saved, retrived and displayed in the respective product page on the frontend.
