To add a custom field to the checkout tab in WooCommerce, you can follow these steps:

  1. Create a custom field using the woocommerce_checkout_fields filter. You can add this code to your theme's functions.php file or create a custom plugin:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
function custom_checkout_field($fields) {
    $fields['extra_field'] = array(
        'type' => 'text',
        'label' => 'Custom Field Label',
        'placeholder' => 'Custom Field Placeholder',
    );
    
    return $fields;
}
add_filter('woocommerce_checkout_fields', 'custom_checkout_field');


  1. Display the custom field on the checkout page by adding the following code to your theme's functions.php file or a custom plugin:
1
2
3
4
5
6
7
8
function display_custom_checkout_field() {
    woocommerce_form_field('extra_field', array(
        'type' => 'text',
        'label' => 'Custom Field Label',
        'placeholder' => 'Custom Field Placeholder',
    ), WC()->checkout->get_value('extra_field'));
}
add_action('woocommerce_after_order_notes', 'display_custom_checkout_field');


  1. Save the custom field value by using the woocommerce_checkout_update_order_meta action hook. Add the following code to your theme's functions.php file or a custom plugin:
1
2
3
4
5
6
function save_custom_checkout_field($order_id) {
    if (!empty($_POST['extra_field'])) {
        update_post_meta($order_id, 'Extra Field', esc_attr($_POST['extra_field']));
    }
}
add_action('woocommerce_checkout_update_order_meta', 'save_custom_checkout_field');


After adding these codes, you should see the custom field displayed on the checkout page in WooCommerce. Customers can enter information in the custom field, and the data will be saved and displayed in the order details in the WooCommerce admin.
