Checklist
General
 Remove all include(), include_once(), require(), require_once()
 Use convention over configuration for autoloading
 Or at least an ext_autoload.php file
 Adapt xclasses
Backend
 Use „_DISPATCH“ as script configuration for backend modules
 BackendUtility::getModuleUrl() and BackendUtility::getAjaxUrl()

4. CPS-IT Mehr Wert im Netz 3
Autoload
 Cache lookup
 Check for core file (namespace TYPO3CMS)
=> Class name reflects folder structure
 Check runtime cache
=> filled with information by loaded ext_autoload.php files
 Get file from class name („extbase convention“)

XCLASS
$GLOBALS['TYPO3_CONF_VARS']['SYS']['Objects']['TYPO3CMSPermControllerPermissionModuleController'] = array(
'className' => 'Tx_BeAcl_Xclass_PermissionModuleController',
);
 GeneralUtility::makeInstance()
 Recursive dissolving

Dispatch
Changeinconf.php
$MCONF['script']='_DISPATCH';
Remove inindex.php
unset($MCONF);
require_once('conf.php');
require_once($BACK_PATH . 'init.php');
require_once($BACK_PATH . 'template.php');

Backend links
$url = TYPO3CMSBackendUtilityBackendUtility::getModuleUrl(
$moduleName,
$urlParameters = array(),
$backPathOverride = FALSE,
$returnAbsoluteUrl = FALSE
);

Ajax links
Register your ajax script
TYPO3CMSCoreUtilityExtensionManagementUtility::registerAjaxHandler(
‘myAjaxId’,
‘MyVendormyExtensionPathToClass.php’
);
> Automatically published to TYPO3.settings.ajaxUrls[‘myAjaxId']
Use your ajax script
Ext.Ajax.request({
url: TYPO3.settings.ajaxUrls[‘myAjaxId']
});

Do‘s
 Old class names still work due to class mapping
 Old hook names still the same
 Use signal / slots

10. CPS-IT Mehr Wert im Netz 9
Connect function to signal
TYPO3CMSCoreUtilityGeneralUtility::makeInstance('TYPO3CMSExtbaseSignalSlot
Dispatcher')->connect(
‘SignalClassName',
‘SignalName’,
‘SlotClassNameOrObject',
‘SlotMethodName'
);
Use signal / slots
Find signal
 Function prefixed with “emit”
 Calls dispatch() function from
TYPO3CMSExtbaseSignalSlotDispatcher
> This way you can introduce own signals

Don‘ts
General
 Prevent any logic in ext_autoload.php configuration (e.g. require
other files)
 No need for t3lib_div::loadTCA()
Eid scripts
 No need to connect to database by tslib_eidtools::connectDB()

12. CPS-IT Mehr Wert im Netz 11
Don‘ts
Extbase
 Database driven object are only stored by calling the repository
functions or persisted manually by calling
$this->objectManager->get(
'TYPO3CMSExtbasePersistenceGenericPersistenceManager‚
)->persistAll();
 Disable the backport of the property mapper
plugin.tx_cpsblogexample.features.rewrittenPropertyMapper = 0
 New functions in
TYPO3CMSExtbasePersistenceGenericQuerySettingsInterface
