Adding a custom message to WooCommerce checkout is a great way to personalize the checkout experience of your customers. You can add security/trust badges or copy to enhance the trust in your site right on that crucial payment page. With custom message on the checkout of your WooCommerce store you can display to your customers a promotional code or even display custom upsell of products by custom condition. (See how to check if the WooCommerce cart contains a product or product category)

Sure you can use a plugin to do that, but more efficient way is to do it with functions.php. Let’s see how it’s done.

In order to add custom content the checkout we will use the special WooCommerce hooks for the WooCommerce Checkout Page, because you want to place that content on a specific place, not anywhere on the checkout. Each WooCommerce checkout hook will display the content on that specific place. Here is a list of those hooks.

PHP Snippet: Add custom content to WooCommerce checkout

Now that we know where we want to be our content, lets actually add it through a function and action. For the demo purpose we’ll add trust badge below the Place order button. Paste the code below in your child theme’s functions.php file.

add_action('woocommerce_review_order_after_payment', 'webroom_add_content_to_woocommerce_checkout', 5);
function webroom_add_content_to_woocommerce_checkout(){
	echo '<div class="trust-badges"><img src=""></div>';

And here is the result:

You can add any conditional or static content/message you want on the desired place on the WooCommerce checkout page.
