Хочется добиться 

'href'        => $this->url->link('product/product', 'path=' . $this->request->get['path'] . '&product_id=' . $result['product_id'])

Но никак не могу понять, как прикрутить переменную path

[Baco]

$check_cat = $this->checkCat($result['product_id']);

if ($check_cat) {
 $path = $check_cat;
} else {
 $path = 0;
}

...


'href'        => $this->url->link('product/product', 'path=' . (int)$path . '&product_id=' . $result['product_id'])


private function checkCat($product_id) {
	$product_id = (int)$product_id;
	if ($product_id < 1) return false;

	static $path = null;
	if (!is_array($path)) {
		$path = $this->cache->get('product.seopath');
		if (!is_array($path)) $path = array();
	}

	if (!isset($path[$product_id])) {
		$query = $this->db->query("SELECT category_id FROM " . DB_PREFIX . "product_to_category WHERE product_id = '" . $product_id . "' ORDER BY main_category DESC LIMIT 1");

		$path[$product_id] = $this->getPathByCategory($query->num_rows ? (int)$query->row['category_id'] : 0);

		$this->cache->set('product.seopath', $path);
		}

	return $path[$product_id];
}

private function getPathByCategory($category_id) {
	$category_id = (int)$category_id;
	if ($category_id < 1) return false;

	static $path = null;
	if (!is_array($path)) {
		$path = $this->cache->get('category.seopath');
		if (!is_array($path)) $path = array();
	}

	if (!isset($path[$category_id])) {
		$max_level = 10;

		$sql = "SELECT CONCAT_WS('_'";
		for ($i = $max_level-1; $i >= 0; --$i) {
			$sql .= ",t$i.category_id";
		}
		$sql .= ") AS path FROM " . DB_PREFIX . "category t0";
		for ($i = 1; $i < $max_level; ++$i) {
			$sql .= " LEFT JOIN " . DB_PREFIX . "category t$i ON (t$i.category_id = t" . ($i-1) . ".parent_id)";
			}
		$sql .= " WHERE t0.category_id = '" . $category_id . "'";

		$query = $this->db->query($sql);

		$path[$category_id] = $query->num_rows ? $query->row['path'] : false;

		$this->cache->set('category.seopath', $path);
	}

	return $path[$category_id];
}

как то так...
