结果页面未显示已筛选的项目打开购物车

所以我正在尝试使用 Opencart 设置一个类似 MVCL 的网站，但是一旦我看到我的过滤列表，我就会选择索引和我希望检索的结果，但它只是导致显示所有内容。

它适用于其他种类，例如按客户排序。

我将解释我认为可能是问题的原因，而不是显示大量代码。

在显示筛选列表之前，用户会看到名为 kit 的索引中项的一组选项。

然后循环此索引，用户选择他们选择的选项（例如丰田将导致所有丰田制造的汽车），但它反而显示所有没有应用过滤器的产品。

        return $query->row;
    }
    public function getKits($data = array()) {
        if ($data) {
            $sql = "SELECT * FROM " . DB_PREFIX . "product_custom group by kit ";
