WooCommerce - 将元数据添加到条纹支付

WooCommerce - Adding Metadata to Stripe Payment

我正在尝试使用以下代码将税务元数据添加到 Stripe 支付插件 after/during 结帐:

/*
* Add "Billing Company" value to Stripe metadata
*/
function filter_wc_stripe_payment_metadata( $metadata, $order, $source ) {

$order_data = $order->get_data();
$order_discount_total = $order_data['discount_total'];
$order_discount_tax = $order_data['discount_tax'];
$order_shipping_total = $order_data['shipping_total'];
$order_shipping_tax = $order_data['shipping_tax'];
$order_total = $order_data['cart_tax'];
$order_total_tax = $order_data['total_tax'];
    $metadata[ __( 'Discount Total', 'woocommerce-gateway-stripe' ) ] = $order_discount_total;
$metadata[ __( 'Discount Tax', 'woocommerce-gateway-stripe' ) ] =  $order_discount_tax;
$metadata[ __( 'Shipping Total', 'woocommerce-gateway-stripe' ) ] = $order_shipping_total;
$metadata[ __( 'Shipping Tax', 'woocommerce-gateway-stripe' ) ] = $order_shipping_tax;
$metadata[ __( 'Cart Tax', 'woocommerce-gateway-stripe' ) ] = $order_total;
$metadata[ __( 'Total Tax', 'woocommerce-gateway-stripe' ) ] = $order_total_tax;

    return $metadata;
}
add_filter( 'wc_stripe_payment_metadata', 'filter_wc_stripe_payment_metadata', 10, 3 );  

使用条带测试模式,此元数据不会出现在元列表中。

来自 API-传递给 Stripe 的请求:

  "invoice": null,
  "livemode": false,
  "metadata": {
    "order_key": "wc_order_a7iTmZVNW52cz",
    "site_url": "https://xxxx.shop",
    "order_id": "2337",
    "payment_type": "single",
    "customer_email": "xxx@xxx-xxx.de",
    "customer_name": "Customer Name"
  },
  "on_behalf_of": null,
  "order": null,  

我错过了什么?
functions.php 更改甚至没有出现在 Woocommerce -> 状态 -> Stripe 日志中。 它已正确添加到 functions.php 中,没有其他内容。谢谢

/*

function filter_wc_stripe_payment_metadata($metadata, $order, $prepared_payment_method) {

    $order_discount_total = $order->get_discount_total();
    $order_discount_tax = $order->get_discount_tax();
    $order_shipping_total = $order->get_shipping_total();
    $order_shipping_tax = $order->get_shipping_tax();

    $order_total_tax = $order->get_total_tax();
    $metadata += ['order_discount_total' => $order_discount_total];
    $metadata += ['order_discount_tax' => $order_discount_tax];
    $metadata += ['order_shipping_total' => $order_shipping_total];
    $metadata += ['order_shipping_tax' => $order_shipping_tax];
    $metadata += ['order_total' => $order_total];
    $metadata += ['order_total_tax' => $order_total_tax];

    return $metadata;
}

add_filter('wc_stripe_payment_metadata', 'filter_wc_stripe_payment_metadata', 10, 3);
