Tutorial Login Menggunakan DX Auth

Setelah melakukan konfigurasi, kita bikin controller dengan nama Auth.php sebagai halaman unutk memproses login. Kemudian kita form sebagai halaman loginnya, misal :

<form method="post" action="<?php echo site_url('auth/login'); ?>">
	<?php  echo $notifikasil; ?>
	<table width="600" cellspacing="0" cellpadding="0">
		<tr>
			<td>Username</td>
			<td><input type="text" name="username" id="username"></td>
		</tr>
		<tr>
			<td>Password</td>
			<td><input type="password" name="password" id="password"></td>
		</tr>
		<tr>
			<td>Ingatkan saya</td>
			<td><input type="checbox" name="remember" id="remember" value="1"></td>
		</tr>
		<tr>
			<td>&nbsp;</td>
			<td><button type="submit" name="login" id="login">Login</button></td>
		</tr>
	</table>
</form>

Setelah controller dibuat dan halaman view unutk form loginya sudah siap, kemudian pada controller Auth.php diisikan potongan script untuk proses login :

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

class Auth extends CI_controller
{
	public function __construct(){
		parent::__construct();
		$this->load->library('Form_validation');
		$this->load->library('DX_Auth');
		$this->load->helper('form');
	}

	public function index(){
		$data = array();
		$data['notifikasi'] = ( $this->session->flashdata('_msg') ) ? $this->session->flashdata('_msg') : null;
		$this->load->view('view_layout_login', $data);
	}

	public function login()
	{
		if( $this->input->post() )
		{
			$val = $this->form_validation;		
			$val->set_rules('username', 'Username', 'trim|required');
			$val->set_rules('password', 'Password', 'trim|required');

			if( $val->run() === FALSE )
			{
				$msg = validation_errors();
			}
			else
			{
				$username = $this->input->post('username',true);
				$password = $this->input->post('password',true);
				$remember = $this->input->post('remember',true);
				
				$login = $this->dx_auth->login($username, $password, $remember);
				if( $login )
				{
					redirect('admin/main');
					exit;
				}
				else
				{
					$msg = $this->dx_auth->get_auth_error();	
				}
			}

			$this->session->set_flashdata('_msg', $msg);
			redirect('auth/index');
			exit;
		}
		else
		{
			show_404();
		}
		
	}

	public function logout()
	{
		$this->dx_auth->logout();
		redirect('auth/index');
		exit;
	}
}

Script diatas merupakan script yang paling simple, anda bisa mengembangkannya sendiri jika diperlukan. Selamat mencoba.
