Our application is now under access control, and any attempt to view non-public pages will redirect you to the login page. However, we will need to create a login view before anyone can login. Add the following to app/views/users/login.ctp if you haven't done so already.

<h2>Login</h2>
<?php
echo $form->create('User', array('url' => array('controller' => 'users', 'action' =>'login')));
echo $form->input('User.username');
echo $form->input('User.password');
echo $form->end('Login');
?>

1. <h2>Login</h2>
2. <?php
3. echo $form->create('User', array('url' => array('controller' => 'users', 'action' =>'login')));
4. echo $form->input('User.username');
5. echo $form->input('User.password');
6. echo $form->end('Login');
7. ?>

If a user is already logged in, redirect him:

function login() {
	if ($this->Session->read('Auth.User')) {
		$this->Session->setFlash('You are logged in!');
		$this->redirect('/', null, false);
	}
}       

1. function login() {
2. if ($this->Session->read('Auth.User')) {
3. $this->Session->setFlash('You are logged in!');
4. $this->redirect('/', null, false);
5. }
6. }

You may also want to add a flash() for Auth messages to your layout. Copy the default core layout - found at cake/libs/view/layouts/default.ctp - to your app layouts folder if you haven't done so already. In app/views/layouts/default.ctp add

$session->flash('auth');

1. $session->flash('auth');

You should now be able to login and everything should work auto-magically. When access is denied Auth messages will be displayed if you added the $session->flash('auth')
