How to Create a Custom Select Field for WooCommerce by Country?

In the ever-evolving world of e-commerce, customization is key to providing a seamless user experience. One way to enhance your WooCommerce store is by implementing a custom select field based on the customer's country. This feature can be particularly useful for businesses that offer country-specific products or services. 

At Cyfuture Cloud, we understand the importance of tailoring your online store to meet your customers' needs, and we're here to guide you through the process of creating this custom field.

Why Implement a Custom Select Field?

Before diving into the implementation, let's explore why a country-based custom select field can benefit your WooCommerce store:

Improved User Experience: By presenting relevant options based on the customer's location, you streamline the shopping process.

Enhanced Product Relevance: Offer country-specific products or services without cluttering the interface for customers from other regions.

Compliance with Local Regulations: Ensure that you're adhering to country-specific rules and regulations in your product offerings.

Step-by-Step Implementation

1. Determine Your Requirements

Before coding, clearly define what you want to achieve with your custom select field. Consider:

Which countries you'll be targeting

What options will be available for each country

How this field will integrate with your existing WooCommerce setup

2. Set Up Your Development Environment

Ensure you have a proper development environment set up. At Cyfuture Cloud, we offer robust cloud hosting solutions that provide an ideal platform for WooCommerce development. Our cloud servers are optimized for WordPress and WooCommerce, ensuring smooth performance during development and production.

3. Create a Custom Plugin

To keep your modifications separate from your theme, create a custom plugin:

a. Navigate to your WordPress plugins directory

b. Create a new folder for your plugin (e.g., 'woo-country-select')

c. Inside this folder, create a PHP file (e.g., 'woo-country-select.php')

4. Write the Plugin Code

In your plugin file, start with the plugin header:

/*

Plugin Name: WooCommerce Country Select

Description: Adds a custom select field based on customer country

Version: 1.0

Author: Your Name

*/

5. Add the Custom Field to WooCommerce Checkout

Use WooCommerce hooks to add your custom field:

add_action('woocommerce_after_order_notes', 'add_custom_country_field');

function add_custom_country_field($checkout) {

    $customer_country = $checkout->get_value('billing_country');

    $options = get_country_specific_options($customer_country);

    woocommerce_form_field('custom_country_field', array(

        'type'    => 'select',

        'class'   => array('custom-field-class form-row-wide'),

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

        'options' => $options,

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

}

6. Create a Function to Get Country-Specific Options

function get_country_specific_options($country) {

    $options = array(

        '' => __('Select an option', 'woocommerce')

    );

    switch ($country) {

        case 'US':

            $options['option1'] = __('US Option 1', 'woocommerce');

            $options['option2'] = __('US Option 2', 'woocommerce');

            break;

        case 'UK':

            $options['option1'] = __('UK Option 1', 'woocommerce');

            $options['option2'] = __('UK Option 2', 'woocommerce');

            break;

        // Add more countries as needed

    }

    return $options;

}

7. Update the Field When Country Changes

Use JavaScript to update the field when the customer changes their country:

add_action('wp_footer', 'custom_country_field_script');

function custom_country_field_script() {

    if (!is_checkout()) return;

    ?>

}

8. Handle the AJAX Request

add_action('wp_ajax_get_country_options', 'get_country_options_ajax');

add_action('wp_ajax_nopriv_get_country_options', 'get_country_options_ajax');

function get_country_options_ajax() {

    $country = $_POST['country'];

    $options = get_country_specific_options($country);

    foreach ($options as $value => $label) {

        echo '' . esc_html($label) . '';

    }

    wp_die();

}

9. Save and Display the Custom Field Value

add_action('woocommerce_checkout_update_order_meta', 'save_custom_country_field');

function save_custom_country_field($order_id) {

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

        update_post_meta($order_id, 'Custom Country Field', sanitize_text_field($_POST['custom_country_field']));

    }

}

add_action('woocommerce_admin_order_data_after_billing_address', 'display_custom_country_field_in_admin');

function display_custom_country_field_in_admin($order) {

    $custom_field = get_post_meta($order->get_id(), 'Custom Country Field', true);

    if ($custom_field) {

        echo '

'.__('Custom Country Field').': ' . $custom_field . '

    }

}
