Feature: #58621 - Unified Backend Routing¶
See Issue #58621
A new Routing component has been added to the TYPO3 Backend which handles addressing different calls / modules inside TYPO3.
A Route is the smallest entity consisting of a path (e.g. "/records/edit/") as well as an identifier for addressing the route, and the information about how to dispatch the route to a PHP controller.
A Route can be a module, wizard or any page inside the TYPO3 Backend. The Router contains the public API for matching paths to fetch a Route and is resolved inside the RequestHandler of the Backend.
The entry point for Routes is
typo3/index.php?route=myroute&token=..... The main RequestHandler for all Backend requests
detects if a route parameter from the server is given and uses this as the route identifier and then resolves to a
controller defined inside the Route.
Routes are defined inside the file "Configuration/Backend/Routes.php" of any extension.
Example of a Configuration/Backend/Routes.php file:
return [ 'myRouteIdentifier' => [ 'path' => '/document/edit', 'controller' => Acme\MyExtension\Controller\MyExampleController::class . '::methodToCall' ] ];
The called method in the controller to be called receives a PSR-7 compliant Request object and a PSR-7 Response object, and has to return a PSR-7 Response object. The UriBuilder generates any kind of URL for the Backend, may it be a module, a typical route or an AJAX call. The UriBuilder returns a PSR-7-conform Uri object that can be casted to string when needed.
$uriBuilder = GeneralUtility::makeInstance(UriBuilder::class); $uri = $uriBuilder->buildUriFromRoute('myRouteIdentifier', array('foo' => 'bar'));
See http://wiki.typo3.org/Blueprints/BackendRouting for more details.
Handling of existing modules works the same as before and fully transparent. Any existing registration of entrypoints can be moved to the new registration file in Configuration/Backend/Routes.php.
