Php 使用自定义付款方式结账后清除会话

我在OpenCart 2.1.0.1中使用信用卡和借记卡的定制支付方式，但我面临一个问题。当我成功购买并重定向到

successs.tpl

页面时，之后当我继续购物（在同一浏览器会话中）并进行第二次成功购买时-它不会记录为具有新订单id的新订单！我将连接我的控制器，它可以是清除会话的代码

如果查看文件

catalog/controller/checkout/success.php

，您将看到成功订单之后的标准流程。如果您已经对其进行了修改，那么OpenCart可能没有取消设置会话数据。在该文件中，控制器检查会话中是否有数据集：

if (isset($this->session->data['order_id'])) {

如果为真，将使用以下行清除购物车：

$this->cart->clear();

并且，在用户活动日志记录之后，会话数据是

unset

，使用以下代码：

unset($this->session->data['shipping_method']);
unset($this->session->data['shipping_methods']);
unset($this->session->data['payment_method']);
unset($this->session->data['payment_methods']);
unset($this->session->data['guest']);
unset($this->session->data['comment']);
unset($this->session->data['order_id']);
unset($this->session->data['coupon']);
unset($this->session->data['reward']);
unset($this->session->data['voucher']);
unset($this->session->data['vouchers']);
unset($this->session->data['totals']);

哇，太棒了！谢谢您！
