Question

我已写下以下代码，以便在订单状态更改完成后发送通知。但我不知道为什么代码不起作用。每当我尝试更改订单状态时，它会重定向到包含500个错误代码的空白页。你能告诉我如何在下面的代码中获得税务细节。

订购后，会向销售代表发送电子邮件通知证实

 add_action("woocommerce_order_status_changed",
 "my_awesome_publication_notification", 10, 3 );

function my_awesome_publication_notification($order_id, $checkout=null) {

    $order = new WC_Order( $order_id );

    $order_total_amount = $order->get_formatted_order_total();  

    $items = $order->get_items();

    foreach ( $items as $item ) {
         $product_name= $item['name'];
        $product_id= $item['product_id'];

    }

    $_product = wc_get_product( $product_id );
    $product_regular_price = $_product->get_regular_price();

    $order_data = $order->get_data();
    $order_date_created = $order_data['date_created'];  
    $order_o_total = $order_data['total'];
    $order_discount_total = $order_data['discount_total'];
    $order_total_tax1 = $order_data['total_tax'];

    if($order->status === 'completed' ) {

        if( $order->get_used_coupons() ) {

            foreach( $order->get_used_coupons() as $coupon) {

                $coupon_name = $coupon;
                /* get coupon's details */
                $coupon_post_obj = get_page_by_title($coupon, OBJECT, 'shop_coupon');
                $coupon_id = $coupon_post_obj->ID;

                $coupons_obj = new WC_Coupon($coupon_id); /* get coupon instance */

                $coupon_discount_amount = $coupons_obj->get_discount_amount();  
                $sales_representative_name          = get_post_meta( $coupon_id, 'sales_representative_name', true );
                $sales_representative_email_address = get_post_meta( $coupon_id, 'sales_representative_email_address', true );
            }

            $to = $sales_representative_email_address;
            $subject = 'New Order Completed Using Assigned Coupon Code';

            $headers  = 'MIME-Version: 1.0' . "\r\n";
            $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
            $headers .= 'From: My Name <nanganstella@gmail.com>' . "\r\n";

            $message = '<html><body>';  
            $message .= '<h1>A new order has been completed using assigned coupon code.<br/></h1>';

            $message .= '<table rules="all" style="border-color: #666;" cellpadding="10">';

            $message .= '<tr><td><strong>Product</strong></td><td>'. $product_name .'</td></tr>';

            $message .= '<tr><td><strong>Coupons used</strong></td><td>'. $coupon_name .'</td></tr>';

            $message .= '<tr><td><strong>Date</strong></td><td>'. $order_date_created .'</td></tr>';

            $message .= '<tr><td><strong>Product Price</strong></td><td>'. $product_regular_price .'CFA</td></tr>';

            $message .= '<tr><td><strong>Order Discount </strong></td><td>'. $order_discount_total.'CFA</td></tr>';

            $message .= '<tr><td><strong>Order Tax </strong></td><td>'. $order_total_tax1 .'</td></tr>';

            $message .= '<tr><td><strong>Order Amount</strong></td><td>'. $order_total_amount .'</td></tr>';                

            $message .= '</table>'; 
            $message .= '</body></html>';

            wp_mail( $to, $subject, $message, $headers );

        }
    }

}

错误：状态调用不正确。不应直接访问订单属性。
