Langkah Awal

1. sesuaikan base url
caranya bisa lihat:

Langkah Selanjutnya

1. Status login disimpan kedalam session jika logout maka nilai didalam session akan dihapus . Penjelasan session codeigniter dapat dilihat di https://www.codeigniter.com/userguide2/libraries/sessions.html

Login.php (..\application\controllers\Login.php )

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

class Login extends CI_Controller {

 
  function __construct(){
 parent::__construct();  
                $this->load->helper( array('url' ,'form' )) ;
                $this->load->library('session');

 }
 public function index()
 {
  $this->load->view('login_form');
 }
 public function authentifikasi()
 {
  $password='admin1';
  $username='komputasistat';
  $array_items = array('username' => $username);
  if($this->input->post('submit')=='Login' && $this->input->post('username')==$username && $this->input->post('password')==$password){
  $this->session->set_userdata('logged_in', $array_items );
  
  }
  else if($this->input->post('submit')=='Logout')
   {
    $this->session->unset_userdata('logged_in', $array_items);


}
  header('location: '.$this->config->base_url()."index.php/login/halamanadmin"); 
  //echo "string".$this->input->post('submit');
 }
 public function halamanadmin(){

  $this->load->view('halaman_admin');
 }
}

*username= komputasistat, password= admin1

2.
login_form.php (..\application\views\login_form.php )

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
?><!DOCTYPE html>
<html lang="en">
<head>

</head>
<body>
<?php 
echo form_open('login/authentifikasi');
echo 'username: '.form_input('username').'<br/>';
echo 'password: '.form_password('password').'<br/>';
echo form_submit('submit', 'Login');

echo form_close();
?>

</body>
</html>

3. Halaman admin hanya bisa diakses apabila berstatus login. Jika tidak berstatus login maka akan dilempar ke halaman login.

halaman_admin.php (..\application\views\halaman_admin.php).

<html>
<?php
if ($this->session->userdata['logged_in']['username']==false) {

header('location: '.$this->config->base_url());
}else{
$username = $this->session->userdata['logged_in']['username'];

}
?>
<body>
 <h1>Selamat Datang, <?php echo $username ?></h1>
 <h3>Halaman ini hanya bisa diakses oleh admin</h3>
 <?php
echo form_open('login/authentifikasi');
echo form_submit('submit', 'Logout');
echo form_close();
?>

</body>
</html>

}
  header('location: '.$this->config->base_url()."index.php/login/halamanadmin"); 
  //echo "string".$this->input->post('submit');
 }
 public function halamanadmin(){

  $this->load->view('halaman_admin');
 }
}
