//controller
function login()
{
$this->form_validation->set_rules('username','username','required');
if($this->form_validation->run() == FALSE)
 {
   //form_login error
 }
else
  {
    $u = $this->input->post('username');
    $pw = md5($this->input->post('username'));
    $valid = $this->Mpelanggan->validate($u,$pw);
    if($valid !== FALSE)
    {
       $_SESSION['username'] = $this->input->post('username');
       //gimana meristerkan session yang ada di model berdasarkan $this->input->post('username');
       redirect('pelanggan');
    }
  }
}

 //Model
 function validate($u,$pw)
	{
		$data = array();
		$this->db->select('id_pelanggan','nama_lengkap','email','alamat','alamat_dikirim','jenis_kelamin','tlp');
		$this->db->where('username', $u);
		$this->db->where('password', $pw);
		$this->db->limit(1);
		$Q = $this->db->get('pelanggan');
		if($Q->num_rows() > 0)
		{
			foreach($Q->result_array() as $row)
			{
			$data = array(
                                 'id_pelanggan' => $row['id_pelanggan'],
                                 'nama_lengkap' => $row['nama_lengkap'],
                                 'email' => $row['email'],
                                 'alamat' => $row['alamat'],
                                 'alamat_dikirim' => $row['alamat_dikirim'],
                                 'jenis_kelamin' => $row['jenis_kelamin'],
                                 'tlp' => $row['tlp'],								    );
			}
		}
 
		$Q->free_result();
		return $data;
	}

 //view
<?php 
	if (isset($_SESSION['username']))
	{
		echo '<fieldset class="bacg2">';
		echo $_SESSION['username'];
		echo anchor('pelanggan/logout','Logout', 'class="button"');
		echo '</fieldset>';
	}
	else
	{
?>
 
<?php echo form_open('pelanggan/login'); ?>
<fieldset class="bacg2">
 
<p>
Username<?php echo form_error('username', '<div class="error">', '</div>'); ?>
<input type="text" name="username" value="<?php set_value('username'); ?>" class="login_input"/>
</p><br />
<p>
Password<?php echo form_error('password', '<div class="error">', '</div>'); ?>
<input type="password" name="password" class="login_input"/>
</p>
 
<input type="submit" name="submit" value="Login" class="button"/>
<?php echo anchor('pelanggan', 'Daftar', 'class="button"'); ?>
</fieldset>
<?php echo form_close(); }?>

jadi intinya yang saya tanyakan Gimana mendaftarkan session di controller, lalu di cek di view kalau sessionnya ada akan ditampilkan dan kalau tidak ada form loginnya yang di tampilkan... ??? sudah 2 hari saya coba g bisa2... thanks..n_n
