Почему-то не работает
в catalog\controller\product\category.php добавил
$data['products'][] = array(
'reviews' => $result['reviews'],
'product_id' => $result['product_id'],
'thumb' => $image,
'name' => $result['name'],
'description' => utf8_substr(trim(strip_tags(html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8'))), 0, $this->config->get('theme_' . $this->config->get('config_theme') . '_product_description_length')) . '..',
'price' => $price,
'special' => $special,
'tax' => $tax,
'minimum' => $result['minimum'] > 0 ? $result['minimum'] : 1,
'rating' => $result['rating'],
'href' => $this->url->link('product/product', 'path=' . $this->request->get['path'] . '&product_id=' . $result['product_id'] . $url)
);
в catalog\view\theme\default\template\product\category.twig
{% if product.rating %}
<a href="{{ product.href }}#tab-review"><i class="fa fa-comment"></i> {{ product.rating }}</a>
<div class="rating"> {% for i in 1..5 %}
