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!

add_action( 'wp_footer', 'bbloomer_add_jscript_checkout', 9999 );

function bbloomer_add_jscript_checkout() {
   global $wp;
	if ( is_checkout() && empty( $wp->query_vars['order-pay'] ) && ! isset( $wp->query_vars['order-received'] ) ) {
      echo '<script>paste your script here!</script>';
   }
}

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
