This document discusses extending TYPO3 applications using Extbase. It introduces new methods and examples for a news system. Dependency injection, signals/slots, and cached classes are presented as methods introduced with Extbase. XClass and hooks are discussed as previous methods for extending TYPO3 before Extbase. The document provides examples of mapping classes and connecting slots to demonstrate these extension techniques.

Estendere applicazioni extbase
- 1. Estendere applicazioni extbase Nuovi metodi ed esempi con news system Presentato da: Cristian Buja T3Camp Italia 2014 Milano 14 - 15 marzo
- 3. Sulla strada di TYPO3 ed Extbase
- 4. Metodi precedenti ad extbase Xclass Hooks
- 5. Xclass prima di TYPO3 6.0 ext_localconf. php ext:example ux_backend.php associazione 2 3 1dichiarazione backend.php typo3 3 REQUISITI
- 6. Xclass prima di TYPO3 6.0 3 associazione in ext_localconf.php $GLOBALS['TYPO3_CONF_VARS'][TYPO3_MODE]['XCLASS']['typo3/backend.php'] = 'typo3conf/examples/xclass/ux_backend.php' 1 dichiarazione in typo3/backend.php if (defined('TYPO3_MODE') && $GLOBALS['TYPO3_CONF_VARS'][TYPO3_MODE]['XCLASS']['typo3/backend.php']) { include_once($GLOBALS['TYPO3_CONF_VARS'][TYPO3_MODE]['XCLASS']['typo3/backend.php']); } 2 sintassi del nome file ux_[nome_classe].php
- 7. TYPO3 6.0 rompe le catene! ext_localconf.php $GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects'] ['TYPO3CMSBackendControllerNewRecordController'] = array ( 'className' => 'DocumentationExamplesXclassNewRecordController' ); Solo associazione !
- 8. Cambiamenti nelle classi statiche Deprecated t3lib_div Use TYPO3CMSCoreUtilityGeneralUtility GeneralUtility::makeInstance() GeneralUtility::callUserFunction() GeneralUtility::getUserObj()
- 9. Hooks remains the same…? Estensioni $TYPO3_CONF_VARS['EXTCONF'][ extension_key ][ sub_key ] = value Core $TYPO3_CONF_VARS['SC_OPTIONS'][ main_key ][ sub_key ][ index ] = function_reference Moduli BE $TBE_MODULES_EXT[ backend_module_key ][ sub_key ] = value
- 10. Metodi introdotti con extbase Dependency Injection Signal / Slot
- 11. Dependency Injection (DI) Injection Extbase /** * @var Tx_Extbase_Object_ObjectManagerInterface $objectManager */ protected $objectManager; /** * @param Tx_Extbase_Object_ObjectManagerInterface $objectManager * @return void */ public function injectObjectManager ( Tx_Extbase_Object_ObjectManagerInterface $objectManager ) { $this->objectManager = $objectManager; }
- 12. Dependency Injection (DI) Injection Extbase > 4.7 /** * @var TYPO3CMSExtbaseSignalSlotDispatcher * @inject */ protected $signalSlotDispatcher; @inject is Comment the code
- 13. Dependency Injection (DI) Costructor injection /** * @param TYPO3CMSExtbaseObjectManagerInterface $objectManager */ public function __constructor(TYPO3CMSExtbaseObjectManagerInterface $objectManager) { $this->objectManager = $objectManager; } Initialize Object /** * Additional inizialization */ public function inizializeObject() { ... }
- 14. Object manager: istanziare oggetti GeneralUtility::makeIstance() ObjectManager->get() /** * @var TYPO3CMSExtbaseObjectObjectManagerInterface * @inject */ protected $objectManager; public function foo () { ... $cObj = $this->objectManager ->get('TYPO3CMSFrontendContentObjectContentObjectRenderer'); ... }
- 15. Extbase: Mappatura delle classi Typoscript Setup: config.tx_extbase.object { TYPO3CMSExtbasePersistenceGenericStorageBackendInterface { className = TYPO3CMSExtbasePersistenceGenericStorageTypo3DbBackend } } Injection + Typoscript
- 16. Extbase: Mappatura delle classi Typoscript Setup: plugin.tx_example.object { TYPO3CMSExtbasePersistenceGenericStorageBackendInterface { className = TYPO3CMSExtbasePersistenceGenericStorageTypo3DbBackend } } Extbase > 6.1 Ovverride global config Power Up!
- 17. Signal / Slot TYPO3CMSExtbaseSignalSlotDispatcher.php public function connect ( $signalClassName, $signalName, $slotClassNameOrObject, $slotMethodName, $passSignalInformation = TRUE ) { … } public function dispatch ( $signalClassName, $signalName, array signalArguments = array() ) { … } Paradigma Event / Observer
- 18. Dispatcher injection TYPO3CMSExtbaseMvcControllerAbstractController.php /** * Injects the signal slot dispatcher * * @param TYPO3CMSExtbaseSignalSlotDispatcher $signalSlotDispatcher */ public function injectSignalSlotDispatcher( TYPO3CMSExtbaseSignalSlotDispatcher $signalSlotDispatcher ) { $this->signalSlotDispatcher = $signalSlotDispatcher; } Dispatcher
- 19. Connect Slot ExampleController.php /** * Injects the signal slot dispatcher * * @param TYPO3CMSExtbaseSignalSlotDispatcher $signalSlotDispatcher */ public function initializeObject () { $this->signalSlotDispatcher->connect( ... ); } Dispatcher Observer Observer Observer
- 20. Dispatch signal TYPO3CMSExtbaseMvcControllerActionController.php $this->signalSlotDispatcher->dispatch( __CLASS__, 'beforeCallActionMethod', array( 'controllerName' => get_class($this), 'actionMethodName' => $this->actionMethodName, 'preparedArguments' => $preparedArguments ) ); Dispatcher Observer Observer Observer Event
- 21. Dove mettere le connessioni allo slot? ext_localcong.php $signalSlotDispatcher = TYPO3CMSCoreUtilityGeneralUtility ::makeInstance('TYPO3CMSExtbaseObjectObjectManager') -> get('TYPO3CMSExtbaseSignalSlotDispatcher'); $signalSlotDispatcher->connect( ... );
- 22. Work around in news system + metodi al domain object? + action a un controller? Dependency Injection + estensioni agiscono sulle medesime classi?
- 23. Work around in news system
- 24. Cached class Resources/Private/extend-news.txt Domain/Model/News Classes/Domain/Model/News.php class News extends Tx_News_Domain_Model_News { protected $newField; public function getNewField() { … } public function setNewField($newField) { … } }
- 25. Cached class ext_localconf.php $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tcemain.php'] ['clearCachePostProc'][$_EXTKEY . '_classcache'] = 'EXT:' . $_EXTKEY . '/Classes/Cache/ClassCacheBuilder.php:Tx_News_Cache_ClassCacheBuilder->build'; Cosa fa?
- 26. Cached class typo3temp/Cache/Code/cache_phpcode/Domain_Model_News.php class Tx_News_Domain_Model_News extends Tx_Extbase_DomainObject_AbstractEntity { … … /*********************************************************************** this is partial from: /var/www/html/typo3conf/ext/example/Classes/Domain/Model/News.php ***********************************************************************/ protected $newField; public function getNewField() { … } public function setNewField($newField) { … } }
