Smarty指定，计算10％

Question

需要帮助！ 在prestashop中，我想从total_to_pay计算出10％的值 任何人都可以帮我添加吗？

$this->smarty->assign(array(
            'total_to_pay' => Tools::displayPrice($params['total_to_pay'], $params['currencyObj'], false),
            'chequeName' => $this->chequeName,
            'chequeAddress' => Tools::nl2br($this->address),
            'status' => 'ok',
            'id_order' => $params['objOrder']->id
        ));

Answer 1

像这样的10％

'total_to_pay' => Tools::displayPrice($stats_sales['sales'] * 10 / 100, $params['currencyObj'], false)
