Try this

Code:

function is_logged_in(){
  $is_logged_in = $this->session->userdata('is_logged_in');
  
  //echo $is_logged_in;
  if ($is_logged_in !== true){
   echo "Necesitas iniciar sesion como usuario para ver este contenido <br />";
   echo anchor('login','Login');
  /*echo "<pre>";
  print_r($this->session->all_userdata());
  echo "</pre>";*/
   die();
  }
}
