Übersicht• XCLASS on steroids• Globaler Namespace in Fluid• Argumente für Partials• Request Handler• Objekthierarchien auf Datenbankebene• Propertyabhängige Validierung• Fluid Goodies

XCLASS on steroids• Klassen und Interface-Implementierungen werden per TypoScript registriertconfig.tx_extbase { objects { Tx_Extbase_MVC_Controller_FlashMessages { className = Tx_T3Ak12_MVC_Controller_FlashMessageContainer } Tx_T3Ak12_MyObjectInterface { className = Tx_T3Ak12_Domain_Model_MyObject } }}• t3lib_div::makeInstance vs. Tx_Extbase_Object_ObjectManager$myObject = t3lib_div::makeInstance(Tx_T3Ak12_Domain_Model_MyObject);$myObject = $this->objectManager->get(Tx_T3Ak12_MyObjectInterface);Der Object Manager ruft – im Gegensatz zu makeInstance() – nach dem Konstruktor zuerst existierendeinject* Methoden und dann initializeObject() auf.

XCLASS on steroids• Implementierunginterface Tx_T3Ak12_MyObjectInterface { public function setValue(array $data);}class Tx_T3Ak12_Domain_Model_MyObject implements Tx_T3Ak12_MyObjectInterface { protected $data; public function setValue(array $data) { $this->data = $data; }}• Injectionclass Tx_T3Ak12_Controller_MyController { /** * @var Tx_T3Ak12_MyObjectInterface */ protected $myObject; /** * @param Tx_T3Ak12_MyObjectInterface $myObject */ public function injectMyObject(Tx_T3Ak12_MyObjectInterface $myObject) { $this->myObject = $myObject; }}

Globaler Namespace in Fluid• Globale Anmeldung eines Namespaces in Fluid-Templates für Standard-Librariesconfig.tx_extbase { objects { Tx_Fluid_Core_Parser_TemplateParser { className = Tx_T3Ak12_View_TemplateParser } }}class Tx_T3Ak12_View_TemplateParser extends Tx_Fluid_Core_Parser_TemplateParser { protected $namespacesBase = array(); public function initializeObject() { $this->namespacesBase = $this->namespaces += array( t3ak12 => Tx_T3Ak12_ViewHelpers ); } protected function reset() { $this->namespaces = $this->namespacesBase; }}Der Namespace steht nun global in Fluid-Templates zur Verfügung:<t3ak12:customViewHelper foo=“bar“ />

Argumente für Partials• Übergabe aller Templatevariablen über {_all} ab TYPO3 4.6 möglich<f:render partial="ListElement" arguments="{_all}" />• Backport für TYPO3 4.5class Tx_T3Ak12_Core_ViewHelper_TemplateVariableContainer extends Tx_Fluid_Core_ViewHelper_TemplateVariableContainer { static protected $reservedVariableNames = array( true, false, on, off, yes, no, _all ); public function get($identifier) { if ($identifier === _all) { return $this->variables; } if (!array_key_exists($identifier, $this->variables)) { // throw Exception here ... } return $this->variables[$identifier]; } public function exists($identifier) { if ($identifier === _all) { return TRUE; } return array_key_exists($identifier, $this->variables); }}

Request Handler• Aufbereitung des Requests in verschiedenen Scopes: Web (FE/BE), CLI,WebService• z.B. FrontendRequestHandler: Verifizierung des Request Hash, Cache Handling• CLI Request Handler ab TYPO3 4.7 verfügbar• LwEnetMultipleActionForms -> Aufbereitung des Request mit Session-Datenconfig.tx_extbase.mvc.requestHandlers { Tx_T3Ak12_Web_FrontendRequestHandler = Tx_T3Ak12_Web_FrontendRequestHandler}class Tx_T3Ak12_Web_FrontendRequestHandler ... { public function handleRequest() { … $this->dispatcher->dispatch($request, $response); return $response; } public function canHandleRequest() { // Can this request be handled } public function getPriority() { return 110; // Priority chain }}

Objekthierarchien auf Datenbankebene Product Socks Shirt Men Women

Objekthierarchien auf Datenbankebene• Basisklasse: Übergreifende Eigenschafteninterface Tx_T3Ak12_Domain_Model_ProductInterface extends Tx_Extbase_DomainObject_DomainObjectInterface{ public function getName(); public function setName($name); public function getPrice(); public function setPrice($price);}class Tx_T3Ak12_Domain_Model_Product extends Tx_Extbase_DomainObject_AbstractEntity implementsTx_T3Ak12_Domain_Model_ProductInterface { protected $name; public function getName() {code for getter} public function setName($name) {code for setter} protected $price; public function getPrice() {code for getter} public function setPrice($price) {code for setter}}

Objekthierarchien auf Datenbankebene• Erweiterte Produktklasseinterface Tx_T3Ak12_Domain_Model_ShirtInterface { public function getColor(); public function setColor($color); public function getSize(); public function setSize($size);}class Tx_T3Ak12_Domain_Model_Shirt extends Tx_T3Ak12_Domain_Model_Product implementsTx_T3Ak12_Domain_Model_ShirtInterface { protected $color; public function getColor() {code for getter} public function setColor($color) {code for setter} protected $size; public function getSize() {code for getter} public function setSize($size) {code for setter}}

Objekthierarchien auf Datenbankebene• Repositories: Über findAll() werden nur die entsprechenden Objekte geliefertclass Tx_T3Ak12_Domain_Repository_ProductRepository extends Tx_Extbase_Persistence_Repository {}class Tx_T3Ak12_Domain_Repository_ShirtRepository extends Tx_T3Ak12_Domain_Repository_ProductRepository {}• TCA$TCA[tx_lwsmaproducts_domain_model_product][ctrl][type] = record_type;• Mappingconfig.tx_extbase.persistence.classes { Tx_T3Ak12_Domain_Model_Product { mapping.tableName = tx_t3ak12_domain_model_product mapping.recordType = Tx_T3Ak12_Domain_Model_Product subclasses { Tx_T3Ak12_Domain_Model_Shirt = Tx_T3Ak12_Domain_Model_Shirt } } Tx_T3Ak12_Domain_Model_Shirt { mapping.tableName = tx_t3ak12_domain_model_product mapping.recordType = Tx_T3Ak12_Domain_Model_Shirt }}

Propertyabhängige Validierung• Property kann nicht in Abhängigkeit zu anderen Properties validiert werden• kein Zugriff auf andere Property-Werte innerhalb eines Property-Validators /** * @var string * @validate StringLength(minimum=42) */protected $property;• Standardlösung in extbase: ModelValidator• Automatischer Aufruf, keine Registrierung notwendig, Aufruf nach Property-Validatorenclass Tx_T3Ak12_Domain_Model_ModelName extends Tx_Extbase_DomainObject_AbstractEntity {}class Tx_T3Ak12_Domain_Validator_ModelNameValidator extends Tx_Extbase_Validation_Validator_AbstractValidator { public function isValid($object) { $isValid = TRUE; if ($object->getSecondProperty() === foo ) { $notEmptyValidator = $this->validatorResolver->createValidator(NotEmpty); $isValid = $notEmptyValidator->isValid($object->getFirstProperty()); } return $isValid; }}

Propertyabhängige Validierung• validatePropertyConstraint in LwEnetMultipleActionForms/** * firstProperty * * @var string * @validatePropertyConstraint $secondProperty Equal(valueList=foo,baz) -> NotEmpty */protected $firstProperty;

Fluid Goodies• Partials einer anderen Extension rendern• Externe Partials können verschachtelt werden• Innerhalb von Forms verwendbar → Tokengenerierung<fx:render partial="Foo/Bar/Baz" arguments="{_all}" extensionName="T3Ak12" />• String-Vergleich für if-ViewHelper<f:if condition="{object.property} == abc"> baz</f:if>
