WooCommerce Change Coupon Code To Discount Code

Pre-Requisites

There are no pre-requisites for this code snippet to work. Keep in mind this solution consists of two code snippets, one to display the content and one to style it.

How To Implement This Solution?

Add these two code snippets as separate entries in either your active child theme’s functions.php file or the Code Snippets plugin.

About The Snippet

In some contexts, “coupon” might not be the most appropriate term. To address this, we’ve created several guides on renaming “coupon” to various popular synonyms. This particular guide focuses on replacing the word “coupon” with “discount.” Although changing “coupon code” to “discount code” isn’t as straightforward as it might seem, we’ve provided a handy code snippet that will update the term wherever it appears on the front end, including in the cart and checkout.
