The programming language is rarely the problem.

<?phpnamespace AcmeDemoController;use TYPO3FLOW3MvcControllerActionController;class HelloWorldController extends ActionController { /** * @param string $name * @return void */ public function greetAction($name) { $this->view->assign(name, $name); }}

<html> <head> <title>Fluid Example</title> </head> <body> <p>Hello, {name}!</p> </body></html>

<?phpnamespace AcmeDemoController;use TYPO3FLOW3MvcControllerActionController;use AcmeDemoDomainModelBook;class BookController extends ActionController { /** * @return void */ public function indexAction() { $book = new Book(); $book->setTitle(Manual del Guerrero de la Luz); $books = array($book); $this->view->assign(books, $books); }}

<ul> <f:for each="{books}" as="book"> <li>{book.title}</li> </f:for></ul>

4 Model

public function createAction(Book $book) { if (!$this->securityManager->hasRole(BookAdmin)) { throw new Exception(Not allowed.); } $statementHandle = $this->databaseHandle->prepare( INSERT INTO "books" ("identifier", "title", "isbn") . VALUES (?, ?, ?) ); $result = $statementHandle->execute( array($book->getId(), $book->getTitle(), $book->getIsbn()) ); if ($result === FALSE) { throw new Exception(Could not create book.); }}

class Book extends BaseModel { protected $id; protected $title; protected $isbn; … public function __construct() { $this->id = TYPO3FLOW3UtilityAlgorithms::generateUUID(); } … public function getSalesVolume() { if (!$this->securityManager->hasRole(Management)) { throw new Exception(Access Denied); } $statementHandle = $this->databaseHandle->prepare( SELECT "identifier" FROM "orders" WHERE "date">?

Dependency6 Injection

class Foo { protected static $instance; public function getInstance() { if (self::$instance === NULL) { self::$instance = new self; } return self::$instance; }}class Bar { public function action() { $foo = Foo::getInstance(); }}

class ServiceLocator { protected static $services = array(); public function get($serviceName) { return self::$services[$serviceName]; }}class Bar { public function action() { $foo = ServiceLocator::get(Foo); }}

class Bar { /** * @var Foo */ protected $foo; /** * @param Foo $foo */ public function __construct(Foo $foo) { $this->foo = $foo; } /** * @return string */ public function action() { $this->foo->doSomething(); }}

class Bar { /** * @var Foo * @FLOW3Inject */ protected $foo; /** * @return string */ public function action() { $this->foo->doSomething(); }}

namespace AcmeDemoAspect;use TYPO3FLOW3AopJoinPoint;use TYPO3FLOW3AnnotationsAround;class BetterWorldAspect { /** * Advice which tweaks the HelloWorld controller * * @param JoinPoint $joinPoint * @Around("method(.*Controller->greetAction())") */ public function someAdvice(JoinPoint $joinPoint) { $name = $joinPoint->getMethodArgument(name); return sprintf("%s, youre running out of time!", $name); }}

Robert, you’re running out of time!

10 Command Line

/** * Kickstart a new action controller * * Generates an Action Controller with the given name in the specified package. * In its default mode it will create just the controller containing a sample * indexAction. * * By specifying the --generate-actions flag, this command will also create a * set of actions. If no model or repository exists which matches the * controller name (for example "CoffeeRepository" for "CoffeeController"), * an error will be shown. * * Likewise the command exits with an error if the specified package does not * exist. By using the --generate-related flag, a missing package, model or * repository can be created alongside, avoiding such an error. * * By specifying the --generate-templates flag, this command will also create * matching Fluid templates for the actions created. This option can only be * used in combination with --generate-actions. * * The default behavior is to not overwrite any existing code. This can be * overridden by specifying the --force flag.
