In the catalog/controller/product/category.php file, find the timeline
$data['products'][] = array(
then add to array
'rating' => $result['rating'], 'manufacturer' => $result['manufacturer'], // <= это нужно добавить
Initially, in the ModelCatalogProduct class (model) ModelCatalogProduct static getProducts() method does not receive data for the manufacturer from the database. Need to fix it.
Edit the getProducts() method in the catalog/model/catalog/product.php getProducts()
in SELECT query add
m.name as manufacturer
and additionally in the request to register the connection with the manufacturer
LEFT JOIN " . DB_PREFIX . "manufacturer m ON p.manufacturer_id = m.manufacturer_id
Then in the template category.tpl display the manufacturer (inside the foreach iterator)
<?php echo $product['manufacturer']; ?>
