appear on:

<?php

// load the catalog library

require_once ‘include/catalog.inc.php’;

// load the URL factory

require_once ‘include/url_factory.inc.php’;

// load the SimpleGeoTarget library

require_once ‘include/simple_geo_target.inc.php’;

// retrieve the product details

$product_id = $_GET[‘product_id’];

$products = Products::get($product_id);

$product = $products[0];

// retrieve the category details and create the category link

$category_id = $_GET[‘category_id’];

$categories = Categories::get($category_id);

$category = $categories[0];

$category_url = make_category_url($category[‘name’], $category[‘id’]);

// redirect to the proper URL if necessary

$proper_url = make_category_product_url($category[‘name’], $category_id,

$product[‘name’], $product_id);

fix_url($proper_url);

// retrieve the brand details

$brand_id = $product[‘brand_id’];

$brands = Brands::get($brand_id);

$brand = $brands[0];
