如何向 Woocommerce 结帐添加额外字段并显示在编辑订单页面中

Question

我在我的 WooCommerce 结帐中额外添加了三个字段（CVR 编号、参考编号和 ønsket leveringsdato）。它们在结账时正确显示，但一旦下订单，信息就不会发送到 WooCommerce backend/order 概览。我如何发送信息以便我们接收？

    function add_woocommerce_billing_fields($billing_fields){

    //reorder woo my billing address form fields
    $billing_fields2['billing_first_name'] = $billing_fields['billing_first_name'];
    $billing_fields2['billing_last_name']  = $billing_fields['billing_last_name'];

    $billing_fields2['billing_vat'] = array(
        'type' => 'text',
        'label' =>  __('CVR nummer',  'keyelp-shop-customization' ),
        'class' => array('form-row-wide'),
        'required' => true,
        'clear' => true
    );

    $billing_fields2['billing_ref'] = array(
        'type' => 'text',
        'label' =>  __('Reference nummer',  'keyelp-shop-customization' ),
        'class' => array('form-row-wide'),
        'required' => false,
        'clear' => true
    );

    $billing_fields2['billing_date'] = array(
        'type' => 'text',
        'label' =>  __('Ønsket leveringsdato',  'keyelp-shop-customization' ),
        'class' => array('form-row-wide'),
        'required' => false,
        'clear' => true
    );
        
    $merged_billing_fields = $billing_fields2 + $billing_fields;

    return $merged_billing_fields;

}

您可以使用 woocommerce_checkout_update_order_meta 和 woocommerce_admin_order_data_after_billing_address 动作挂钩。代码进入您的原生主题 functions.php 文件。

Using woocommerce_checkout_update_order_meta hook you can save value meta.

function custom_checkout_field_update_order_meta( $order_id ) {
    if ( $_POST['billing_vat'] ){ 
        update_post_meta( $order_id, 'billing_vat', esc_attr($_POST['billing_vat']) );
    }
    if ( $_POST['billing_ref'] ){ 
        update_post_meta( $order_id, 'billing_ref', esc_attr($_POST['billing_ref']) );
    }
    if ( $_POST['billing_date'] ){ 
        update_post_meta( $order_id, 'billing_date', esc_attr($_POST['billing_date']) );
    }
}
add_action('woocommerce_checkout_update_order_meta', 'custom_checkout_field_update_order_meta');

Using woocommerce_admin_order_data_after_billing_address hook you can display meta value after billing address.

function custom_checkout_field_display_admin_order_meta($order){
    echo '<p><strong>'.__('CVR nummer').':</strong> ' . get_post_meta( $order->get_id(), 'billing_vat', true ) . '</p>';
    echo '<p><strong>'.__('Reference nummer').':</strong> ' . get_post_meta( $order->get_id(), 'billing_ref', true ) . '</p>';
    echo '<p><strong>'.__('Ønsket leveringsdato').':</strong> ' . get_post_meta( $order->get_id(), 'billing_date', true ) . '</p>';
}
add_action( 'woocommerce_admin_order_data_after_billing_address', 'custom_checkout_field_display_admin_order_meta', 10, 1 );
