Quick backend in CakePHP

cake-backend.markdown

Add a quick backend to CakePHP

Add to config/core.php:

<?php
Configure::write('Routing.prefixes', array('admin'));

Add login, logout and entry point for the backend in config/routes.php, insert whatever controller you want to start in:

<?php
Router::connect('/login', array('controller' => 'users', 'action' => 'login'));
Router::connect('/logout', array('controller' => 'users', 'action' => 'logout'));
Router::connect('/admin', array('controller' => 'whatever', 'action' => 'index', 'admin' => true));

Add Controller/UsersController.php:

<?php
class UsersController extends AppController
{
	public function login() {
		if($this->request->isPost()) {
			if($this->Auth->login()) {
				$this->Session->setFlash(__('Login successful'));
				$this->redirect($this->Auth->redirect());
			} else {
				$this->Session->setFlash(__('Wrong username or password!'));
			}
		}
	}
	
	public function logout() {
		$this->Session->setFlash(__('Logout successful'));
		$this->redirect($this->Auth->logout());
	}
}

Add View/Users/login.ctp:

<?php echo $this->Session->flash('auth'); ?>
<h2><?php echo __('Backend'); ?></h2>
<p><?php echo __('Please enter your username and password.'); ?></p>
<?php echo $this->Form->create('User'); ?>
	<?php echo $this->Session->flash(); ?>
	<?php echo $this->Form->input('username'); ?>
	<?php echo $this->Form->input('password'); ?>
<?php echo $this->Form->end(__('Login')); ?>

Add a new table to the database:

CREATE TABLE `users` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(100) NOT NULL DEFAULT '',
  `password` varchar(200) NOT NULL DEFAULT '',
  `created` datetime NOT NULL,
  PRIMARY KEY (`id`)
)

To generate a password, paste this code into the login view:

<?php
App::uses('AuthComponent', 'Controller/Component');
echo AuthComponent::password('PASSWORT');

Add a user to the new table.

Add the Auth-Component to Controller/AppController.php:

<?php
public $components = array(
	'Session',
	'Auth' => array(
		'loginRedirect' => array('controller' => 'whatever', 'action' => 'index', 'admin' => true),
		'logoutRedirect' => array('controller' => 'whatever', 'action' => 'index', 'admin' => false),
		'loginAction' => array('controller' => 'users', 'action' => 'login', 'admin' => false),
		'authError' => 'Login to see this area.'
	)
);

Make sure that all admin views require authentication in Controller/AppController.php:

<?php
public function beforeFilter() {
	if(!empty($this->params['prefix']) && $this->params['prefix'] == 'admin') {
		$this->Auth->deny();
		$this->layout = 'admin';
	} else {
		$this->Auth->allow();
	}
}
