what is admin in "redirect('admin/Dashboard');". Did you made any changes to url in route file?

When you do this
if ($result) {
$user = array(
'id' => $result['id'],
'username' => $result['username'],
'password' => $result['password']
);
$this->session->set_userdata($user);
redirect('admin/Dashboard');
You are setting your password in your session cookie. All you really need to do is set your username. You should also do something like this in Login function index()
if(result){
$user = array(
'name' => $result['username]',
'is_logged_in' => TRUE //add this to your session data
);
$this->session->set_userdata($user);
}
Then create a method in whatever controller you are using
public function is_logged_in()
{
$is_logged_in = $this->session->userdata('is_logged_in');
if (!isset($is_logged_in) || $is_logged_in != true)
{
redirect("admin/Login");
}
}
When you are in your Dashboard you can use $this->is_logged_in(); to make sure no one else gets into your Dashboard or forms. Use it at the top of your methods for forms or just getting into your dashboard Then use something like this on your pages
if($this->session->userdata('username') == true){
echo "Hello " . $this->session->userdata('username'). nbs(3), anchor("admin/Dashboard", " Go To Dashboard "); //this is all you need to get to your Dashboard if you are logged in.
}else {
echo " "; //doesnt show up if not logged in
}?>
That acts as a link on your pages that only shows up if you are logged in. At the top of all your Dashboard controller methods add the $is_logged_in();
