在Opencart中添加文本传送值

Question

我们在OpenCart中收到订单后提供电子邮件报价。如何在OpenCart中添加一个字段来显示TBC而不是£0.00。我们使用X-Shipping作为我们的4种送货方式：

这可能吗？

以下是目录端的PHP代码

<?php
class ModelShippingXshipping extends Model {

            if (!$this->config->get('xshipping_geo_zone_id'.$i)) {
                $status = true;
            } elseif ($query->num_rows) {
