在 open cart 2.0.3.1 中，现在小计正在计算而不减去折扣 . 但我需要减去总折扣 .
请查看图片以获取具体示例 . http://postimg.org/image/lff2g1qff/
我修改了文件 /catalog/model/total/sub_total.php
在 $sub_total = $this->cart->getSubTotal(); 之后
已经下面的代码来获得小计 - 折扣
$total_discount_total = $this->cart->getTotalDiscounts();
$total_discount_value = 0; // initialize total discount;
foreach($total_discount_total as $value){
$total_discount_value = $total_discount_value + $value;
}
$display_sub_total = $sub_total - $total_discount_value;
在 $total_data[] = array 中，已将 'value' => .. 行 $sub_total 更改为 $display_sub_total
但它给出了以下错误 .
致命错误：在第7行的/home/public_html/catalog/model/total/sub_total.php中调用未定义的方法Cart :: getTotalDiscounts（）
我不是代码专家 . 任何人都可以帮我修改这段代码吗？
下面是代码 .
catelog/model/total/sub_total.php
<?php
class ModelTotalSubTotal extends Model {
public function getTotal(&$total_data, &$total, &$taxes) {
$this->load->language('total/sub_total');
$sub_total = $this->cart->getSubTotal();
if (isset($this->session->data['vouchers']) && $this->session->data['vouchers']) {
foreach ($this->session->data['vouchers'] as $voucher) {
$sub_total += $voucher['amount'];
}
