WooCommerce: Add custom fields with ease

Guide to adding custom fields via WordPress code and plugins

Adding fields in WooCommerce allows the website to collect additional information from customers, improving the shopping experience and order management.

This guide will explore how to add custom fields in different areas of WooCommerce: at checkout, in the user account and in the registration form.

Add fields to your WooCommerce checkout

It is possible to add fields to the WooCommerce checkout using the woocommerce_checkout_fields filter or a dedicated plugin . Below is an example of php code to add a custom field:

add_filter( 'woocommerce_checkout_fields' , 'custom_checkout_field' );

function custom_checkout_field( $fields ) {
    $fields['billing']['custom_field'] = array(
        'label'     => __('Campo Personalizzato', 'woocommerce'),
        'placeholder'   => _x('Inserisci il dato', 'placeholder', 'woocommerce'),
        'required'  => true,
        'clear'     => false,
        'type'      => 'text',
        'priority'  => 22,
    );
    return $fields;
}

Add fields in WooCommerce account

To add custom fields to your user account page, you can take advantage of the woocommerce_edit_account_form filter . Here’s how you could do it:

add_action( 'woocommerce_edit_account_form', 'custom_user_profile_fields' );

function custom_user_profile_fields() {
    ?>
    <p class="woocommerce-form-row woocommerce-form-row--wide form-row form-row-wide">
    <label for="custom_field"><?php _e('Campo Personalizzato', 'woocommerce'); ?>&nbsp;<span class="required">*</span></label>
    <input type="text" class="woocommerce-Input woocommerce-Input--text input-text" name="custom_field" id="custom_field" value="">
    </p>
    <?php
}

Add fields to the WooCommerce registration form

Adding fields to the registration form requires the use of the woocommerce_register_form filter . Below is an example of how to modify the file by adding a field:

add_action( 'woocommerce_register_form', 'add_custom_registration_fields' );

function add_custom_registration_fields() {
    ?>
    <p class="woocommerce-form-row woocommerce-form-row--wide form-row form-row-wide">
        <label for="reg_custom_field"><?php _e('Campo Personalizzato', 'woocommerce'); ?><span class="required">*</span></label>
        <input type="text" class="woocommerce-Input woocommerce-Input--text input-text" name="custom_field" id="reg_custom_field" value="<?php if ( ! empty( $_POST['custom_field'] ) ) echo esc_attr( $_POST['custom_field'] ); ?>" />
    </p>
    <?php
}

Save custom field data

Regardless of the location of custom fields, it is critical to save the data entered by users.

This can be done via the woocommerce_checkout_update_order_meta hook for the checkout fields, woocommerce_save_account_details for the user account fields, and woocommerce_created_customer for the registration fields.

add_action( 'woocommerce_checkout_update_order_meta', 'save_custom_checkout_field' );

function save_custom_checkout_field( $order_id ) {
    if ( ! empty( $_POST['custom_field'] ) ) {
        update_post_meta( $order_id, 'Custom Field', sanitize_text_field( $_POST['custom_field'] ) );
    }
}

Implementing custom fields in WooCommerce can significantly enrich data collection and improve order management, leading to higher customer satisfaction and improved operational efficiency. Use code appropriately and always test changes in a staging environment before applying them to your live site.

Add custom fields with plugins

Adding custom fields in WooCommerce can also be managed through the use of plugins, which offer a more accessible solution for less code-savvy users or for those looking for a quicker and more intuitive way. Plugins allow you to extend the functionality of WooCommerce without having to write custom code. Below, we’ll explore how to use plugins to add custom fields in different areas of WooCommerce.

1. Add Fields to Checkout with Plugin

WooCommerce Checkout Field Editor is one of the most popular plugins for customizing checkout page fields. With the checkout field editor plugin, you can add, delete or edit fields on the checkout page. Here’s how to use it:

• Install the plugin and activate it from the WordPress Plugin Directory.
• Go to WooCommerce > Settings > Checkout Fields.
• Here, you can add new fields using the plugin interface. Choose the field type, enter labels and decide if the field is required.
• Save your changes to apply them.

2. Add Fields to User Account with Plugin

WooCommerce Edit Account Page allows you to easily customize your user account page by adding custom fields. After installing and activating the plugin:

• Access the plugin configuration via the WooCommerce menu.
• Follow the instructions to add new fields to your user profile page.
• Configure the settings for each field, as required or optional, and save.

3. Add Fields to the Registration Form with Plugin

To add custom fields to the registration form, you can use Profile Builder – User Profile & User Registration Forms. This plugin is not specific to WooCommerce but is fully compatible and offers the flexibility to add fields to the WooCommerce registration form:

• After installing and activating the plugin, go to Profile Builder > Form Fields.
• Here, you can add custom fields that will appear on the registration form.
• Configure each field as per your needs and save your changes.

Saving and Managing Custom Field Data

Most custom field plugins in WooCommerce will automatically save data entered by users into custom fields, without the need for additional code or components. Additionally, they offer options to view and manage this data in the WordPress backend, making it easy to manage orders and user profiles.

Conclusions

Using plugins to add custom fields in WooCommerce is a practical and accessible solution that can greatly simplify the process of customizing your e-commerce site. Whether you want to collect additional information during checkout, improve user profiles or customize the registration form, there is a plugin that can meet your needs. Always remember to test each new feature in a staging environment before applying it to your live site to ensure the best possible experience for your customers.
