Load different data depending on URL?

try this

Code:

function index($param_1 = FALSE, $param_2 = FALSE, $param_3 = FALSE) {

  $data = array('entities'=>array(), 'title'=>'', 'main'=>'public_page');

  if (empty($param_1) && empty($param_2) && empty($param_3)) {
    $data['title'] = 'no specific category chosen';
  } else {
     $data['title'] = !empty($param_1) ? 'country' : $data['title'];
     $data['title'] = !empty($param_2) ? 'city' : $data['title'];
     $data['title'] = !empty($param_3) ? 'category' : $data['title'];
  }

  $data['entries'] = $this->Mains->get_entries($param_1, $param_2, $param_3);
  $this->load->vars($data);
  $this->load->view('template');
}

If that does not work I think you need to confirm what values you are actually receiving for each of the params
add the following as the first statements for the function

Code:

echo $param_1.'::'.$param_2.'::'.$param_3.'<br />';

because i have a feeling the problem is that there is no controller and method in the url
the url should probably be
http://www.site.com/index.php/[controller]/index/scotland/glasgow/hotels/
[controller] because i do not know what the controller is
