• Can be optional or required.

2. Custom Order Notes

• Can be added by customers or store administrators.
• Help track special instructions, complaints, or changes related to the order.

How to Add Custom Order Notes and Fields in WordPress (WooCommerce)

Method 1: Using a Plugin (Beginner-Friendly Approach)

Several WooCommerce plugins can help you add custom order notes and fields without coding. Some popular options include:

1. WooCommerce Checkout Field Editor
2. Flexible Checkout Fields
3. WooCommerce Custom Fields

Steps to Add Custom Fields Using a Plugin:

1. Install and activate the desired plugin.
2. Navigate to WooCommerce > Settings > Checkout Fields.
3. Click “Add New Field” and configure the settings (type, label, required status).
4. Save changes and test the checkout process.

Method 2: Adding Custom Fields via Code (Advanced Users)

If you prefer a custom-coded solution, you can add fields using WooCommerce hooks.

Adding a Custom Checkout Field

Add the following code to your theme’s functions.php file:

// Add custom field to checkout page
function custom_checkout_field($checkout) {
    echo '<div id="custom_checkout_field"><h3>'.__('Additional Information').'</h3>';
    woocommerce_form_field('custom_order_note', array(
        'type' => 'text',
        'class' => array('form-row-wide'),
        'label' => __('Custom Order Note'),
        'placeholder' => __('Enter special instructions here'),
    ), $checkout->get_value('custom_order_note'));
    echo '</div>';
}
add_action('woocommerce_after_order_notes', 'custom_checkout_field');

// Save custom field value
function save_custom_checkout_field($order_id) {
    if (!empty($_POST['custom_order_note'])) {
        update_post_meta($order_id, 'custom_order_note', sanitize_text_field($_POST['custom_order_note']));
    }
}
add_action('woocommerce_checkout_update_order_meta', 'save_custom_checkout_field');

Displaying the Custom Field in the Admin Panel

// Display custom field in admin order edit page
function display_custom_order_field($order){
    $custom_note = get_post_meta($order->get_id(), 'custom_order_note', true);
    if ($custom_note) {
        echo '<p><strong>'.__('Custom Order Note:').'</strong> ' . esc_html($custom_note) . '</p>';
    }
}
add_action('woocommerce_admin_order_data_after_billing_address', 'display_custom_order_field', 10, 1);

Method 3: Using WooCommerce Hooks & Filters

WooCommerce provides hooks such as woocommerce_checkout_fields and woocommerce_admin_order_data_after_billing_address, which allow developers to modify checkout fields dynamically.

• Use Clear Labels and Descriptions: Ensure users understand what each field is for.
• Validate and Sanitize User Input: Prevent security vulnerabilities by cleaning user inputs.
• Test Thoroughly: Check the functionality on different devices and browsers.

    $custom_note = get_post_meta($order->get_id(), 'custom_order_note', true);
