根据Woocommerce电子邮件通知中的配送方式显示自定义内容

Question

Woocommerce更新到3.2后，下面的代码不再有效。

add_action( 'woocommerce_email_order_details', 'my_completed_order_email_instructions', 10, 4 );
function my_completed_order_email_instructions( $order, $sent_to_admin, $plain_text, $email ) {

    // Only for "Customer Completed Order" email notification
    if( 'customer_completed_order' != $email->id ) return;

    // Comptibility With WC 3.0+
    if ( method_exists( $order, 'get_id' ) ) {
        $order_id = $order->get_id();
    } else {
        $order_id = $order->id;
    }
    //$order->has_shipping_method('')
    $shipping_method_arr = get_post_meta($order_id, '_shipping_method', false); // an array
    $rate_id = $shipping_method_arr[0][0]; // the rate ID

    if ( 'flat_rate:10' == $rate_id ){
        echo pll__("Text 1");
    } else {
        echo pll__("Text 2");
    }
}

此代码中有哪些错误或过时
需要进行哪些更改才能使其重新工作？

以下是获取订单中使用的装运方法并使此功能按预期工作的正确方法：

add_action( 'woocommerce_email_order_details', 'my_completed_order_email_instructions', 10, 4 );
function my_completed_order_email_instructions( $order, $sent_to_admin, $plain_text, $email ) {

    // Only for "Customer Completed Order" email notification
    if( 'customer_completed_order' != $email->id ) return;

    $found = false; // Initializing variable

    // Iterating through Order shipping methods
    foreach($order->get_shipping_methods() as $value){
        $rate_id = $value->get_method_id(); // Get the shipping rate ID
        if ( 'flat_rate:10' == $rate_id )
            $found = true;
    }

    if ($found)
        echo '<p>'.__("Text 1 (found)","woocommerce").'</p>';
    else
        echo '<p>'.__("Text 2 (else)","woocommerce").'</p>';
}

代码进入函数。活动子主题（或主题）或任何插件文件中的php文件。
