в cart.php добавлял
if ((float)$product['special']) {
$this->data['special'] = $this->currency->format($this->tax->calculate($product['special'], $product['tax_class_id'], $this->config->get('config_tax')));
} else {
$this->data['special'] = false;
}
if ($this->config->get('config_tax')) {
$this->data['tax'] = $this->currency->format((float)$product_info['special'] ? $product['special'] : $product['price']);
} else {
$this->data['tax'] = false;
}
$discounts = $this->model_catalog_product->getProductDiscounts($this->request->get['product_id']);
$this->data['discounts'] = array();
foreach ($discounts as $discount) {
$this->data['discounts'][] = array(
'quantity' => $discount['quantity'],
'price' => $this->currency->format($this->tax->calculate($discount['price'], $product_info['tax_class_id'], $this->config->get('config_tax')))
);
}
и еще добавил тут несколько строк
$this->data['products'][] = array(
'key' => $product['key'],
'thumb' => $image,
'name' => $product['name'],
'model' => $product['model'],
'option' => $option_data,
'quantity' => $product['quantity'],
'stock' => $product['stock'] ? true : !(!$this->config->get('config_stock_checkout') || $this->config->get('config_stock_warning')),
'reward' => ($product['reward'] ? sprintf($this->language->get('text_points'), $product['reward']) : ''),
'price' => $price,
'special' => $special,
'tax' => $tax,
'total' => $total,
'href' => $this->url->link('product/product', 'product_id=' . $product['product_id']),
'remove' => $this->url->link('checkout/cart', 'remove=' . $product['key'])
);
