Simple Auth with Users HABTM Groups in CakePHP

Submitted by brett on Sun, 05/10/2008 - 4:04am
In almost every project I need to setup some sort of login, and usually it requires group access to certain data depending on different criteria. For example I may have groups Admin+Member and I want Members to only be able to see other Users Profiles if the other Profile is active.

Little Helper

This function checks if the user is in a group. config/bootstrap.php 
<?php
function in_group($group,$groups) {
	if (isset($groups['Group'])) {
		$groups = $groups['Group'];
	}
	if (!$groups || !is_array($groups) || empty($groups)) {
		return false;
	}
	$allow = false;
	foreach($groups as $_group) {
		if ($_group['name'] == $group) {
			$allow = true;
			break;
		}
	}
	return $allow;
}
?>

The Tables

# users
CREATE TABLE IF NOT EXISTS `users` (
  `id` int(11) NOT NULL auto_increment,
  `username` char(50) NOT NULL,
  `password` char(50) NOT NULL,
  `active` tinyint(4) NOT NULL default '0',
  `email` varchar(255) NOT NULL,
  PRIMARY KEY  (`id`)
);
# groups
CREATE TABLE IF NOT EXISTS `groups` (
  `id` int(11) NOT NULL auto_increment,
  `name` varchar(128) NOT NULL,
  `created` datetime default NULL,
  `modified` datetime default NULL,
  PRIMARY KEY  (`id`)
);
# groups_to_users
CREATE TABLE IF NOT EXISTS `groups_to_users` (
  `group_id` int(11) NOT NULL,
  `user_id` int(11) NOT NULL,
  PRIMARY KEY  (`group_id`,`user_id`)
);

The Models

Before we get started, lets setup the models. I have added some validation to get you started. app_model.php 
<?php
class AppModel extends Model {
	function validUnique($value,$field){
		if (is_array($field)) {
			foreach($field as $v) $field = $v;
		}
		$conditions = array();
		$conditions["{$this->name}.{$field}"] = $value;
		if (isset($this->id) && $this->id) {
			$conditions["{$this->name}.{$this->primaryKey}"] = "!={$this->id}";
		}
		$this->recursive = -1;
		return !$this->hasAny($conditions);
	}
    function required($field) {
    	foreach($field as $k=>$v){}
    	return $v?true:false;
	}
}
?>
models/user.php 
<?php
class User extends AppModel {

    var $name = 'User';
    var $displayField = 'username';

    var $validate = array(
        'username' => array(
			'not unique' => array(
				'rule'=>array('validUnique','username'),
				'required' => true,
			),
            'must be alpha-numeric' => array(
				'rule' => 'alphaNumeric',
				'required' => true,
			),
			'required field' => array(
				'rule' => 'required',
				'required' => true,
			),
        ),
        'email' => array(
			'not unique' => array(
				'rule'=>array('validUnique','email'),
				'required' => true,
			),
            'invalid email' => array(
				'rule'=>'email',
				'required' => true,
			),
			'required field' => array(
				'rule' => 'required',
				'required' => true,
			),
        ),
        'password_confirm' => array(
            'does not match' => array(
				'rule' => 'validPasswordConfirm',
				'required' => false,
			),
        ),
    );
    
	var $hasAndBelongsToMany = array(
		'Group' => array(
			'className' => 'Group',
			'joinTable' => 'groups_to_users',
			'foreignKey' => 'user_id',
			'associationForeignKey' => 'group_id',
			'with' => 'GroupToUser',
		),
	);    

    function validPasswordConfirm($value){
        if ($this->data[$this->alias]['password_change'] != $this->data[$this->alias]['password_confirm']) {
            return false;
        }
        return true;
    }
}
?>
models/group.php 
<?php
class Group extends AppModel {
	var $name = 'Group';
	var $validate = array(
		'name' => array(
			'required field' => array(
				'rule' => 'required',
				'required' => true,
			),
			'not unique' => array(
				'rule'=>array('validUnique','name'),
				'required' => true,
			),
		),
	);	
}
?>

The Controllers

The app_controller will do the work of setting the related Groups into the Auth data. app_controller.php 
<?php
class AppController extends Controller {
    var $components = array('Auth');

	function beforeFilter() {
        $this->__setAuthUser();

		// allow pages to be displayed to anyone
		if ($this->name=='Pages') {
	   		$this->Auth->allow('display');
		}

        parent::beforeFilter();
	}

	function __setAuthUser() {
		$this->Auth->userScope = array('User.active = 1');

		// read the auth info
		$auth = $this->Session->read('Auth');

		// set the auth users groups		
		if (!isset($auth['GroupUser']) || $auth['GroupUser']!=$auth['User']['id']) {
			$User = ClassRegistry::init('User');
			$auth = $User->find('first',array('conditions'=>array('User.id'=>$this->Auth->user('id'))));
			$auth['GroupUser'] = $this->Auth->user('id');
		}

		// check permissions for admin access		
		if(isset($this->params[Configure::read('Routing.admin')])) {
			if (isset($auth['User']['id']) && !in_group('admin',$auth)) {
				$this->_flash(__('You do not have permission to access the administration.',true),'error');
				$this->redirect(array('admin'=>false,'controller'=>'users','action'=>'login'));
			}
		}

		// save and set the auth info
		$this->Session->write('Auth',$auth);
		$this->set('auth',isset($auth['User'])?$auth:false);
	}

	function _flash($message,$type='message') {
		$messages = (array)$this->Session->read('Message.multiFlash');
		$messages[] = array('message'=>$message, 'layout'=>'default', 'params'=>array('class'=>$type));
		$this->Session->write('Message.multiFlash', $messages);
	}

}
?>
Next I have provided a fully working users_controller, complete with account register, account management and lost password email. I have also included some extra goodies such as habtm checkbox, breadcrumbs, search and multi-actions. controllers/users_controller.php 
<?php
class UsersController extends AppController {
	var $name = 'Users';
	var $components = array('Email');
	
	var $multiActions = array(
		'multi_delete',
	);
	
	function beforeFilter() {
		parent::beforeFilter();
		$this->Auth->allow('register','password');
		if (isset($this->passedArgs['key'])) {
			$this->Auth->allow('account');
		}
	}
	
	//
	// PUBLIC ACTIONS
	//
	function index() {

		$title = 'My Account';

		// set breadcrumb
		$breadcrumb = array();
		$breadcrumb[] = array(

		$breadcrumb[] = array(

		$this->set(compact('title','breadcrumb'));

	}
	
	function account() {
		// load account from key
		if (isset($this->passedArgs['key'])) {

			$user = $this->User->findByPassword($this->passedArgs['key']);
			if (!$user) {
				$this->_flash(__('Invalid Key.', true),'error');
				$this->redirect(array('action'=>'index'));
			}
			$this->Auth->login($user);
		}

		// load account from auth user
		$id = $this->Auth->user('id');
		if (!$id) {
			$this->_flash(__('Invalid User.', true),'error');
			$this->redirect(array('action'=>'index'));
		}
		
		// process submit
		if (!empty($this->data)) {

Hello,

thanks for a nice example!

When I am making above mention files and try to run the script, it gives me below error:

Notice (8): Undefined property: UsersController::$Session [APP\app_controller.php, line 22]
Code

//pr($_SESSION); die;

$auth = $this->Session->read('Auth');

AppController::__setAuthUser() - APP\app_controller.php, line 22

Fatal error: Call to a member function read() on a non-object in C:\wamp\www\cakegroup\app\app_controller.php on line 22

Can you please let me know, why it is showing?

Hope to hear from you soon!

Thanks,

Aditya

Hello,

I've got the same error. Have you solved the problem?

Best,

Did you get this figured out? You need to add 'Session' to your components array in app controller

var $components = array('Auth', 'Session');
