Opencart奖励积分计算每10分钟Rs 1

Question

我正在使用opencart来实现我的ecomm网站。我在其中添加了奖励功能。我希望如果用户有500分，那么它可以相当于Rs 50.但是目前它等于42.51。任何人都可以帮助我。

奖励积分的代码是： -

class ModelTotalReward extends Model {
public function getTotal(&$total_data, &$total, &$taxes) {
    if (isset($this->session->data['reward'])) {
        $this->load->language('total/reward');

        $points = $this->customer->getRewardPoints();

        if ($this->session->data['reward'] <= $points) {
            $discount_total = 0;

            $points_total = 0;

            foreach ($this->cart->getProducts() as $product) {
                if ($product['points']) {
                    $points_total += $product['points'];
                }
            }

            $points = min($points, $points_total);

            foreach ($this->cart->getProducts() as $product) {
                $discount = 0;

                if ($product['points']) {
                    $discount = $product['total'] * ($this->session->data['reward'] / $points_total);

                    if ($product['tax_class_id']) {
                        $tax_rates = $this->tax->getRates($product['total'] - ($product['total'] - $discount), $product['tax_class_id']);

                        foreach ($tax_rates as $tax_rate) {
                            if ($tax_rate['type'] == 'P') {
                                $taxes[$tax_rate['tax_rate_id']] -= $tax_rate['amount'];
                            }
                        }
                    }
                }

                $discount_total += $discount;
            }

            $total_data[] = array(
                'code'       => 'reward',
                'title'      => sprintf($this->language->get('text_reward'), $this->session->data['reward']),
                'value'      => -$discount_total,
                'sort_order' => $this->config->get('reward_sort_order')
            );

            $total -= $discount_total;
        }
    }
}

public function confirm($order_info, $order_total) {
    $this->load->language('total/reward');

    $points = 0;

    $start = strpos($order_total['title'], '(') + 1;
    $end = strrpos($order_total['title'], ')');

    if ($start && $end) {
        $points = substr($order_total['title'], $start, $end - $start);
    }

    if ($points) {
        $this->db->query("INSERT INTO " . DB_PREFIX . "customer_reward SET customer_id = '" . (int)$order_info['customer_id'] . "', order_id = '" . (int)$order_info['order_id'] . "', description = '" . $this->db->escape(sprintf($this->language->get('text_order_id'), (int)$order_info['order_id'])) . "', points = '" . (float)-$points . "', date_added = NOW()");
    }
}

public function unconfirm($order_id) {
    $this->db->query("DELETE FROM " . DB_PREFIX . "customer_reward WHERE order_id = '" . (int)$order_id . "' AND points < 0");
}

}
