WooCommerce: How to Add Scripts to the Checkout Page

A client needed to add her SSL Logo Seal to the checkout page. The problem is that the code she was given had also a JS part, together with a bunch of HTML.

Unfortunately you can’t just copy and paste JavaScript in the checkout page… you need a workaround!

In this article, we will learn about wp_footer, a handy WordPress hook to print anything inside the footer, a bit of conditional logic to target the WooCommerce checkout page only (and therefore excluding the Thank You Page and Order Pay Page), and how to print HTML inside a PHP function. Enjoy!
