Я использую opencart 2.0.1.1, здесь я хочу получить категории в виде вкладки, чтобы нам не нужно было открывать новую ссылку каждый раз, чтобы увидеть товары, связанные с категориями, как показано на изображении ниже, кто-нибудь, пожалуйста, помогите 
я добавил код Catalog/controller/module/product_category.php
foreach ($categories as $category) {
//var_dump($token);die;
$products = $this->model_catalog_product->getProducts(array('filter_category_id' => $category['category'], 'start' => 0, 'limit' => $setting['limit']));
foreach($products as $i => $product_info)
{
if ($product_info) {
if ($product_info['image']) {
$image = $this->model_tool_image->resize($product_info['image'], $setting['width'], $setting['height']);
} else {
$image = $this->model_tool_image->resize('placeholder.png', $setting['width'], $setting['height']);
}
if (($this->config->get('config_customer_price') && $this->customer->isLogged()) || !$this->config->get('config_customer_price')) {
$price = $this->currency->format($this->tax->calculate($product_info['price'], $product_info['tax_class_id'], $this->config->get('config_tax')));
} else {
$price = false;
}
if ((float)$product_info['special']) {
$special = $this->currency->format($this->tax->calculate($product_info['special'], $product_info['tax_class_id'], $this->config->get('config_tax')));
} else {
$special = false;
}
if ($this->config->get('config_tax')) {
$tax = $this->currency->format((float)$product_info['special'] ? $product_info['special'] : $product_info['price']);
} else {
$tax = false;
}
if ($this->config->get('config_review_status')) {
$rating = $product_info['rating'];
} else {
$rating = false;
}
$desc = html_entity_decode($product_info['description'], ENT_QUOTES, 'UTF-8');
$quick_descr_start = strpos($desc,'</iframe>')+9;
if ($quick_descr_start > 9){
$quick_descr = substr($desc, $quick_descr_start);
}else{
$quick_descr = $desc;
}
$data['products'][$k][] = array(
'title' => $category['name'],
'product_id' => $product_info['product_id'],
'thumb' => $image,
'name' => $product_info['name'],
'manufacturer' => $product_info['manufacturer'],
'description' => utf8_substr(strip_tags(html_entity_decode($product_info['description'], ENT_QUOTES, 'UTF-8')), 0, $this->config->get('config_product_description_length')) . '..',
'price' => $price,
'special' => $special,
'tax' => $tax,
'rating' => $rating,
'author' => $product_info['manufacturer'],
'description1' => $quick_descr,
'model' => $product_info['model'],
'allow' => $product_info['minimum'],
'href' => $this->url->link('product/product', 'product_id=' . $product_info['product_id']) );
}
}
$k++;
}

я добавил две категории, чтобы получить вкладку, но она показывает мне одну и ту же вкладку дважды подряд.
