How to Create Checkbox Field In WooCommerce Checkout Page

Adding a checkbox to your WooCommerce checkout page is a small but powerful step to build trust, ensure consent, and improve user experience. Whether you want customers to agree to terms, subscribe to newsletters, or provide preferences, a simple checkbox can make a big difference.

However, adding custom fields like checkboxes can be tricky if done incorrectly, affecting user experience or checkout functionality. In this guide, you’ll learn how to create a checkbox field in WooCommerce checkout pages quickly, safely, and without coding headaches.

Let’s begin!

Why Add a Checkbox Field to WooCommerce Checkout?

Before creating a checkbox field on your WooCommerce checkout page, I will tell you why you should do it!

Creating a checkbox field in your WooCommerce checkout page is a small but mighty addition that can significantly enhance user experience and compliance. This handy tool ensures customers are well-informed and agree to essential terms before purchasing.

Using a checkbox field in your WooCommerce checkout page allows customers to express their preferences or consent with a simple click. This lets you gather important customer preferences and consent, ensuring you stay on the right side of legal and ethical practices.

So, integrating a checkbox field is a smart, user-friendly way to enhance your checkout process, benefiting both your business and your customers.

How to Create a Checkbox Field in the WooCommerce Checkout Page?

Now that you know the importance of the checkbox field on your WooCommerce checkout page, I will tell you how to create a checkbox field step by step.

Step 1: Add the Checkbox

Firstly, you need to add the checkbox. To do that,

• Go to your WordPress Dashboard
• Select Appearance > Theme file editor
• Find your functions.php and add the following code to it;

Here is the function for adding the checkbox:

function cw_custom_checkbox_fields( $checkout ) {

    echo '<div class="cw_custom_class"><h3>' . esc_html__( 'Separation Heading:', 'your-text-domain' ) . '</h3></div>';

    woocommerce_form_field( 'custom_checkbox', array(

        'type'          => 'checkbox',

        'label'         => esc_html__( 'Aggregation Policy', 'your-text-domain' ),

        'required'      => true,

    ), $checkout->get_value( 'custom_checkbox' ));

}

Here is the hook for adding the checkbox:

add_action('woocommerce_after_order_notes', 'cw_custom_checkbox_fields');

Step 2: Set the Condition to ‘Required’

Now, you need to set the conditions for the field. For that, the field must be set to required.

So, if a user leaves this field empty, an error message will be generated. Since the error notification function add_error() has been depreciated, I will use wc_add_notive():

add_action('woocommerce_checkout_process', 'cw_custom_process_checkbox');

function cw_custom_process_checkbox() {

    global $woocommerce;

    if (!$_POST['custom_checkbox'])

        wc_add_notice( __( 'Notification message.' ), 'error' );

}

At this point, the checkbox has been added to the WooCommerce checkout page.

Step 3: Save the Customer Data

Remember that the information provided by the buyer through the custom field needs to be saved along with other data from the checkout page. Here is how the data from the checkbox will be saved with the other data:

add_action('woocommerce_checkout_update_order_meta', 'cw_checkout_order_meta');

function cw_checkout_order_meta( $order_id ) {

    if ($_POST['custom_checkbox']) update_post_meta( $order_id, 'checkbox name', esc_attr($_POST['custom_checkbox']));

}

And that’s it. You’re done.
