How to Add Extra Field to WooCommerce Checkout Page

If you are doing online business, you already know about the significance of a checkout page. Sometimes you might need to do customization on your eCommerce website due to specific requirements. In this tutorial, we will show you how to customize the WooCommerce checkout page and add extra fields to it.

Before jumping to the tutorial, let's find out what a checkout page is.

What is checkout page?

A checkout page is an eCommerce term that refers to a page shown to a customer during the step-by-step checkout process. Generally, it is the most important page for both seller and customer. Customers have to provide important pieces of information like addresses, billing details, payment method on this page. And if somehow this page produces an error, no customer will be able to make any purchase! So we can imagine how important this page is to the sellers.

When you are using WordPress for powering your website and WooCommerce as your eCommerce solution, you also get your own checkout page. However, being a free solution, WooCommerce does not give you the opportunity of customizing your checkout page from settings. So, how are you going to do that?


Add an Extra WooCommerce Checkout Field

Sometimes you barely need to add  WooCommerce custom fields on a checkout page according to our requirements and this can be a real hefty job. This tutorial will guide you through on how to do this. After reading this blog you will be ready to add a custom field to the checkout page. Let's get going to the point.

Imagine that this is your default checkout page.

There is two completely different approach that will help you in adding custom fields to checkout page such as using –

  • custom coding (for coders)
  • plugin (for non-coders)

Through Coding

For the people who know how to code or who has basic coding knowledge can follow this approach. This method adds the custom field to the checkout page using the code given below. To start out with coding, we are ought to do the subsequent steps given below.

First, we need to perform an action to our functions.php file. Copy this entire code to your theme's function.php file.


* Add custom field to the checkout page


add_action('woocommerce_after_order_notes', 'custom_checkout_field');

function custom_checkout_field($checkout)


echo '<div id="custom_checkout_field"><h2>' . __('New Heading') . '</h2>';

woocommerce_form_field('custom_field_name', array(

'type' => 'text',

'class' => array(

'my-field-class form-row-wide'

) ,

'label' => __('Custom Additional Field') ,

'placeholder' => __('New Custom Field') ,

) ,


echo '</div>';


After adding this code, the checkout page should appear as :

For data validation of the custom field you can use the code given below:


* Checkout Process


add_action('woocommerce_checkout_process', 'customised_checkout_field_process');

function customised_checkout_field_process()


// Show an error message if the field is not set.

if (!$_POST['customised_field_name']) wc_add_notice(__('Please enter value!') , 'error');


So we’ve added a replacement field to the checkout page along with the validation check! Great!
Let's confirm that the details entered into the custom field by the client, is being saved or not.

This can be done by using the code below:


* Update the value given in custom field


add_action('woocommerce_checkout_update_order_meta', 'custom_checkout_field_update_order_meta');

function custom_checkout_field_update_order_meta($order_id)


if (!empty($_POST['customised_field_name'])) {

update_post_meta($order_id, 'Some Field',sanitize_text_field($_POST['customised_field_name']));



Tutorial for non-coders (using plugin)

With the above lines of codes, we have added custom fields to our WooCommerce web store!

If you are a non-coder, you also can use a plugin to add a new field to the checkout page. There are many plugins that can be used for this purpose. Some are as follows-

By using these plugins anyone with zero coding knowledge can add extra custom fields to the WooCommerce checkout page. Let's see how to add a field with Checkout Field Editor and Manager for WooCommerce.

Simply install and activate the plugin. You will find a new menu under WooCommerce which is ‘Checkout Fields'. Navigate to WP Admin Dashboard > WooCommerce > Checkout Fields

Checkout Field Editor

On the left side, under Fields option, you can find 6 different types of field. Depending on which type of field you want to add, choose that accordingly. We want to add a field for phone number, so we are choosing Text. We will just drag the Text button to under the name fields.

While adding new fields, noticed how we made the field a required one? You can opt for not doing that if you don't need the field to be a required one.

The same way you can add any type of field that this plugin has to offer.
