更新订单的开票和发货字段

Question

我希望客户在WooCommerce的/ order-pay /页面上输入帐单和运输信息，即单击发票后的去向。

这是我试图在form-pay.php中使用的代码

<!-- Form -->
<h3><?php _e( 'Billing details', 'woocommerce' ); ?></h3>
<?php do_action( 'woocommerce_before_checkout_billing_form', $order ); ?>
<div class="woocommerce-billing-fields__field-wrapper">
    <?php
    $fields = WC()->checkout->get_checkout_fields( 'billing' );
    foreach ( $fields as $key => $field ) {
        $field_name = $key;

        if ( is_callable( array( $order, 'get_' . $field_name ) ) ) {
            $field['value'] = $order->{"get_$field_name"}( 'edit' );
        } else {
            $field['value'] = $order->get_meta( '_' . $field_name );
        }   
        woocommerce_form_field( $key, $field, $field['value'] );
    }
    ?>
</div>
<?php do_action( 'woocommerce_after_checkout_billing_form', $order ); ?>

<h3><?php _e( 'Shipping details', 'woocommerce' ); ?></h3>
<?php do_action( 'woocommerce_before_checkout_shipping_form', $order ); ?>
<div class="woocommerce-shipping-fields__field-wrapper">
    <?php
    $fields = WC()->checkout->get_checkout_fields( 'shipping' );
    foreach ( $fields as $key => $field ) {
        $field_name = $key;

        if ( is_callable( array( $order, 'get_' . $field_name ) ) ) {
            $field['value'] = $order->{"get_$field_name"}( 'edit' );
        } else {
            $field['value'] = $order->get_meta( '_' . $field_name );
        }   
        woocommerce_form_field( $key, $field, $field['value'] );
    }
    ?>
</div>
<?php do_action( 'woocommerce_after_checkout_shipping_form', $order ); ?>

在“立即订购”页面上输入帐单和运输字段后，它将更新订单
