ENCRYPT & SIGN COOKIES

Session::config(array('default' => array(
'adapter' => 'Cookie',
'strategies' => array(
'Hmac' => array('secret' => '$f00bar$'),
'Encrypt' => array('secret' => '$f00bar$')
)
)));

NEST ROUTES
Router::connect("/admin/{:args}", array('admin' => true), array(
'continue' => true
));

Router::connect("/{:locale:en|de|jp}/{:args}", array(), array(
'continue' => true
));

Router::connect("/{:args}.{:type}", array(), array(
'continue' => true
));

HANDLE ERRORS
$method = array(Connections::get('default'), 'read');

ErrorHandler::apply($method, array(), function($error, $params) {
$queryParams = json_encode($params['query']);
$msg = "Query error: {$error['message']}";

Logger::warning("{$msg}, data: {$queryParams}");
return new DocumentSet();
});

PROTECT FORMS
<?=$this->form->create(); ?>
<?=$this->security->requestToken(); ?>
<?=$this->form->field('title'); ?>
<?=$this->form->submit('Submit'); ?>
<?=$this->form->end(); ?>

public function add() {
if (
$this->request->data &&
!RequestToken::check($this->request)
) {
// Badness!!
}
}

HTTP SERVICE CLASSES
$http = new Http(array(
...
'methods' => array(
'do' => array('method' => 'post', 'path' => '/do')
)
));
POST /do HTTP/1.1
$response = $http->do(new Query(array(
…
'data' => array('title' => 'sup')
))); title=sup
// var_dump($response->data());

FILTER / SORT COLLECTIONS

$users->find(array("type" => "author"))->sort("name");

$users->first(array("name" => "Nate"));

MULTIBYTE CLASS

• Supports mbstring, intl, iconv & (womp, womp) plain PHP

• Only one method right now: strlen()

• More would be good… open a pull request

SCHEMA CLASS

• Arbitrary data types

• Arbitrary handlers

• Example: hash modiﬁed passwords before writing

• Other example: JSON en/decode arbitrary data for MySQL

LI3_DOCTRINE2
Connections::add('default', array(
'type' => 'Doctrine',
• Works with Lithium stuff: 'driver' => 'pdo_mysql',
'host' => 'localhost',
'user' => 'root',
• Connections 'password' => 'password',
'dbname' => 'my_db'
));
• Authentication /**
* @Entity
* @Table(name="users")

• Forms */
class User extends li3_doctrine2modelsBaseEntity {
/**
* @Id

• Sessions * @GeneratedValue
* @Column(type="integer")
*/
private $id;

• Validation /**
* @Column(type="string",unique=true)
*/
private $email;
...
}

LI3_FILESYSTEM
use li3_filesystemstorageFileSystem;

FileSystem::config(array(
'default' => array(
'adapter' => 'File'
),
'ftp' => array(
'adapter' => 'Stream',
'wrapper' => 'ftp',
'path' => 'user:password@example.com/pub/'
}
));

FileSystem::write('default', '/path/to/file', $data);

LI3_ACCESS
Access::config(array(
'asset' => array(
'adapter' => 'Rules',
'allowAny' => true,
'default' => array('isPublic', 'isOwner', 'isParticipant'),
'user' => function() { return Accounts::current(); },
'rules' => array(
'isPublic' => function($user, $asset, $options) {
...
},
'isOwner' => function($user, $asset, $options) {
...
},
'isParticipant' => function($user, $asset, $options) {
...
}
)
)
...
);

LI3_ACCESS
Access::config(array(
...
'action' => array(
'adapter' => 'Rules',
'default' => array('isPublic', 'isAuthenticated'),
'allowAny' => true,
'user' => function() { return Accounts::current(); },
'rules' => array(
'isPublic' => function($user, $request, array $options) {
...
},
'isAuthenticated' => function($user, $request, array $options) {
...
},
'isAdmin' => function($user, $asset, $options) {
...
}
)
)
);

LI3_ACCESS
Dispatcher::applyFilter('_call', function($self, $params, $chain) {
$opts = $params['params'];
$request = $params['request'];
$ctrl = $params['callable'];

if ($access = Access::check('action', null, $ctrl, $opts)) {
// Reject
}
if ($access = Access::check('action', null, $ctrl, array('rules' => 'isAdmin') + $opts)) {
// Reject
}
return $chain->next($self, $params, $chain);
});

class PostsController extends Base {

public $publicActions = array('index', 'view');
}

http://bit.ly/li3plugins

RETURN ON REDIRECT


public function view($post) {
if (!$post) {
$this->redirect("Posts::index");
}
// Herp derp
}
}

FAT FILTERS == BAD
Dispatcher::applyFilter('run', function($self, $params, $chain) {
// Herp
// Derp
// Herp
// Derp
// Herp
// Derp
// Herp
// Derp
// Herp
// Derp
// Herp
(repeat x100)
});

DEFINE YOUR SCHEMA!

{
count: 5,
...
}
...
{
count: "5",
...
}

DON’T FEAR THE SUBCLASS
class Base extends lithiumdataModel {

public function save($entity, $data = null, array $options = array()) {
if ($data) {
$entity->set($data);
}
if (!$entity->exists()) {
$entity->created = new MongoDate();
}
$entity->updated = new MongoDate();
return parent::save($entity, null, $options);
}
}

class Posts extends Base {
...
}

QUICK & DIRTY ADMIN
Dispatcher::config(array('rules' => array(
'admin' => array(
'action' => 'admin_{:action}'
)
)));
Router::connect(
public function admin_index() {
'/admin/{:args}',
...
array('admin' => true),
}
array('continue' => true)
);
public function index() {
...
}
}
