我在控制器中注册了产品选项数据的输出，但是如何为他们的每个选项添加购买按钮，以便在单击它时将产品添加到购物车中？

目录/控制器/产品/category.php：

$options = array();
        
        foreach ($this->model_catalog_product->getProductOptions($result['product_id']) as $option) {
            $product_option_value_data = array();

            foreach ($option['product_option_value'] as $option_value) {
                if (!$option_value['subtract'] || ($option_value['quantity'] > 0)) {
                    if ((($this->config->get('config_customer_price') && $this->customer->isLogged()) || !$this->config->get('config_customer_price')) && (float)$option_value['price']) {
                        $price = $this->currency->format($this->tax->calculate($option_value['price'], $result['tax_class_id'], $this->config->get('config_tax') ? 'P' : false), $this->session->data['currency']);
                    } else {
