Вывод товаров по принадлежности к категории

[rsqrsk]

Добрый вечер. 

Вывожу список всех товаров по id в определенном диапазоне, но не устраивает, что это сплошной список.

Подскажите пожалуйста, каким способом лучше отсортировать их хотя бы по главному родителю категорий (товары с главной категорией в админке связаны)?

Например:

Название категории

... продукт

... продукт

... продукт 

Название категории

... продукт

... продукт

... продукт 

 

Список вывожу таким образом:

controller

<?php
class ControllerInformationPricelist extends Controller {
	public function index() {
		$this->document->setTitle($this->config->get('config_meta_title'));
		$this->document->setDescription($this->config->get('config_meta_description'));
		$this->document->setKeywords($this->config->get('config_meta_keyword'));
		
		$this->load->model('catalog/category');
		$this->load->model('catalog/product');
		
		$data['products'] = array();

		$products = array_merge(range(50,100));
		foreach ($products as $product_id) {
			$product_info = $this->model_catalog_product->getProduct($product_id);
			
			//$product_img = $this->model_catalog_product->getProductImages($product_id);	
			
			$discount_info = $this->model_catalog_product->getProductDiscountPrice($product_id);
			foreach ($discount_info as $discount) {
					$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')), $this->session->data['currency'])
					);
			}	
					
			if ($product_info) {
					if ($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')), $this->session->data['currency']);
					} else {

					}

					} else {

					}

						'description' => utf8_substr(strip_tags(html_entity_decode($product_info['description'], ENT_QUOTES, 'UTF-8')), 0, $this->config->get('theme_' . $this->config->get('config_theme') . '_product_description_length')) . '..',
						'price'       => $price,

					);
			}
		}
		
		if (isset($this->request->get['route'])) {
