Code igniter routes making internal server error

Code igniter routes making internal server error

Been stuck on this for hours, hope it is not something to simple.
So I'm trying to route 3 vars from one URL to another with this code:
$route['activate_email/(:any)/(:any)/(:any)'] = "user/activate/$1/$2/$3";
and the user controller code:
public function activate($code='', $email='', $id=''){
die("1");
//Check vars
if(empty($code) || empty($email) || empty($id) ||
!is_numeric(ceil($id))){
die("BAD");
}
//Check details in DB
$result = $this->db->query("SELECT * FROM `companies` WHERE `id` = ?",
array($id))->result_array();
print_r($result);
exit;
}
Thanks for any help
