.. include:: /Includes.rst.txt .. _backend-modules-extbase: .. _backend-modules-template: ==================================== Create a backend module with Extbase ==================================== .. tip:: If you don't want to do extensive data modeling templates can be written :ref:`without Extbase. ` Backend modules can be written using the Extbase/Fluid combination. The factory :php:`TYPO3\CMS\Backend\Template\ModuleTemplateFactory` can be used to retrieve the :php:`\TYPO3\CMS\Backend\Template\ModuleTemplate` class which is - more or less - the old backend module template, cleaned up and refreshed. This class performs a number of basic operations for backend modules, like loading base JS libraries, loading stylesheets, managing a flash message queue and - in general - performing all kind of necessary setups. To access these resources, inject the :php:`TYPO3\CMS\Backend\Template\ModuleTemplateFactory` into your backend module controller: .. code-block:: php use TYPO3\CMS\Backend\Attribute\AsController; use TYPO3\CMS\Backend\Template\ModuleTemplateFactory; use TYPO3\CMS\Extbase\Mvc\Controller\ActionController; #[AsController] final class MyController extends ActionController { public function __construct( protected readonly ModuleTemplateFactory $moduleTemplateFactory, ) { } } .. versionadded:: 12.1/12.4.9 A backend controller can be tagged with the :php:`\TYPO3\CMS\Backend\Attribute\AsController` attribute. This way, the :ref:`registration of the controller ` in the :file:`Configuration/Services.yaml` file is no longer necessary. .. note:: Until TYPO3 v12.4.8 the attribute was named :php:`\TYPO3\CMS\Backend\Attribute\Controller` and has been renamed to :php:`AsController` with TYPO3 v12.4.9. Both work with TYPO3 v12 and v13, but developers should use :php:`#[AsController]` for upwards compatibility, since :php:`#[Controller]` has been deprecated with TYPO3 v13. After that you can add titles, menus and buttons using :php:`ModuleTemplate`: .. code-block:: php // use Psr\Http\Message\ResponseInterface public function myAction(): ResponseInterface { $this->view->assign('someVar', 'someContent'); $moduleTemplate = $this->moduleTemplateFactory->create($this->request); // Adding title, menus, buttons, etc. using $moduleTemplate ... $moduleTemplate->setContent($this->view->render()); return $this->htmlResponse($moduleTemplate->renderContent()); } .. seealso:: :ref:`dropdown-button-components` Using this :php:`ModuleTemplate` class, the Fluid templates for your module need only take care of the actual content of your module. As such, the Layout may be as simple as (again from "beuser"): .. code-block:: html :caption: typo3/sysext/beuser/Resources/Private/Layouts/Default.html and the actual Template needs to render the title and the content only. For example, here is an extract of the "Index" action template of the "beuser" extension: .. code-block:: html :caption: typo3/sysext/beuser/Resources/Private/Templates/BackendUser/Index.html

... The best resources for learning is to look at existing modules from TYPO3 CMS. With the information given here, you should be able to find your way around the code.
