[Solved] Setting up a user redirect

[eluser]riwakawd[/eluser]
I would like to know best way to set up my user redirect. So if user if not logged on and try's to access a page it will redirect to my 'admin'

I have autoloaded the user library and sessions

On the parent construct part of my dashboard controller I have set up my sessions redirect but stops me from logging on. If I remove it I can login fine, very strange. Should let me login while using sessions as a redirect.

Dashboard Controller

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Dashboard extends MX_Controller {

   public function __construct()
   {
      parent::__construct();
      $this->lang->load('admin/common/dashboard', 'english');
      
     if ($this->session->userdata('islogged') && $this->session->userdata('username')) {
       return true;
      } else {
       redirect('admin');
      }

   }

}

Login Controller

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Login extends MX_Controller {
private $error = array();

public function __construct()
   {
      parent::__construct();
      $this->lang->load('admin/common/login', 'english');
   }

public function index()
{

  $this->document->setTitle($this->lang->line('heading_title'));

  if (($this->input->server('REQUEST_METHOD') == 'POST') && $this->validate()) {

   $data_session = array(
    'isLogged' => true,
    'user_id' => $this->user->isLogged(),
    'username' => $this->user->getUserName(),
    //'email' => $this->user->getEmail(),
    'last_logged' => $this->user->last_logged()
   );

   $this->session->set_userdata($data_session);

   redirect('admin/dashboard');
  }

  $data['heading_title'] = $this->lang->line('heading_title');

  $data['text_login'] = $this->lang->line('text_login');
  $data['text_forgotten'] = $this->lang->line('text_forgotten');

  $data['entry_username'] = $this->lang->line('entry_username');
  $data['entry_password'] = $this->lang->line('entry_password');

  $data['button_login'] = $this->lang->line('button_login');

  if (array_key_exists('warning', $this->error)) {
   $data['error_warning'] = $this->error['warning'];
  } else {
   $data['error_warning'] = '';
  }

  $data['action'] = site_url('admin');

  if (trim($this->input->post('username'))) {
   $data['username'] = $this->input->post('username');
  } else {
   $data['username'] = '';
  }

  if (trim($this->input->post('password'))) {
   $data['password'] = $this->input->post('password');
  } else {
   $data['password'] = '';
  }


  return $this->load->view('common/login', $data);
}

protected function validate() {
  if (!trim($this->input->post('username')) || !trim($this->input->post('password')) || !$this->user->login($this->input->post('username'), $this->input->post('password'))) {
   $this->error['warning'] = $this->lang->line('error_login');
  }

  return !$this->error;
}
}

Library

Code:

<?php

class User {
private $user_id;
private $username;
private $last_logged;
//private $getEmail;
private $permission = array();

public function __construct() {
  $this->CI =& get_instance();

  if (trim($this->CI->session->userdata('user_id'))) {
   $user_query = $this->CI->db->query("SELECT * FROM " . $this->CI->db->dbprefix . "user WHERE user_id = '" . (int)$this->CI->session->userdata('user_id') . "' AND status = '1'");

   if ($user_query->num_rows) {
    $this->user_id = $user_query->row('user_id');
    $this->username = $user_query->row('username');
    $this->last_logged = $user_query->row('last_logged');
    //$this->getEmail = $user_query->row('email');

    $this->CI->db->query("UPDATE " . $this->CI->db->dbprefix . "user SET ip = " . $this->CI->db->escape($this->CI->input->ip_address()) . " WHERE user_id = '" . (int)$this->CI->session->userdata('user_id') . "'");

    $now = date("Y-m-d H:i:s");

    $data = array(
               'last_logged' => $now
            );

    $this->CI->db->where('user_id', $this->CI->session->userdata('user_id'));
    $this->CI->db->update('user', $data);
   } else {
    $this->logout();
   }
  }
}

public function login() {
  $username = $this->CI->input->post('username');
  $password = $this->CI->input->post('password');

  $user_query = $this->CI->db->query("SELECT * FROM " . $this->CI->db->dbprefix . "user WHERE username = " . $this->CI->db->escape($username) . " AND (password = SHA1(CONCAT(salt, SHA1(CONCAT(salt, SHA1(" . $this->CI->db->escape($password) . "))))) OR password = " . $this->CI->db->escape(md5($password)) . ") AND status = '1'");

  if ($user_query->num_rows() == 1) {

   $this->user_id = $user_query->row('user_id');
   $this->username = $user_query->row('username');
   $this->last_logged = $user_query->row('last_logged');
   //$this->getEmail = $user_query->row('email');

   return true;
  } else {
   return false;
  }
}

public function logout() {
  //$this->CI->session->sess_destroy();
  $this->CI->session->unset_userdata($this->CI->session->userdata('user_id'));
  $this->user_id = '';
  $this->username = '';
}

public function isLogged() {
  return $this->user_id;
}

public function last_logged() {
  return $this->last_logged;
}

public function getId() {
  return $this->user_id;
}

public function getEmail() {
  return $this->email;
}

public function getUserName() {
  return $this->username;
}
}
