While working on one of the projects realized how is to created fully functional login form using CakePHP framework. For people who are not familiar with it please visit : http://cakephp.org/ for more information. I am also thinking about writing a small tutorial on how to set this framework up, but it will be later.

So let’s assume you already have CakePHP set up and all you have your ‘user’ table in the database.

First of all lets create login.ctp :

 <?php
   if ($session->check(‘Message.auth’)) $session->flash(‘auth’); // If authentication message it exist it will be displayed
   echo $form->create(‘User’, array(‘action’ => ‘login’)); // creating user form with 2 fields email and password
   echo $form->input(’email’);
   echo $form->input(‘password’);
   echo $form->end(‘Login’);
?>

Now lets edit our user_controller.php (we don’t need to edit much because CakePHP is taking care of everything):

function logout() {
  $this->redirect($this->Auth->logout());
}
function beforeFilter() { //function that enables people to register without logging in
  $this->Auth->allow(‘add’);
  parent::beforeFilter();
}

And the last piece is AppController .

Edit app_controller.php :

class AppController extends Controller {
  var $components = array(‘Auth’);
  function beforeFilter() {
    $this->Auth->userModel = ‘User’;
    $this->Auth->fields = array(‘username’ => ’email’, ‘password’ => ‘password’);
    $this->Auth->loginAction = array(‘admin’ => false, ‘controller’ => ‘users’, ‘action’ => ‘login’);
    $this->Auth->loginRedirect = array(‘controller’ => ‘users’, ‘action’ => ‘index’);
  }
}

There is not much to say about the code above, to my mind it is very simple to read.

And that is it. This is a benefit of developing on the existing framework. Such things as login is already included, all you need is just to properly call it.
