string

addErrorFlashMessage()

If an error occurred during this request, this adds a flash message describing the error to the flash message container.

protected addErrorFlashMessage() : void
Internal

callActionMethod()

Calls the specified action method and passes the arguments.

protected callActionMethod(RequestInterface $request) : ResponseInterface

If the action returns a string, it is appended to the content in the response object. If the action doesn't return anything and a valid view exists, the view is rendered automatically.

Parameters
$request : RequestInterface
Internal
Return values
ResponseInterface

errorAction()

A special action which is called if the originally intended action could not be called, for example if the arguments were not valid.

protected errorAction() : ResponseInterface

The default implementation sets a flash message, request errors and forwards back to the originating action. This is suitable for most actions dealing with form input.

We clear the page cache by default on an error as well, as we need to make sure the data is re-evaluated when the user changes something.

Return values
ResponseInterface

forwardToReferringRequest()

If information on the request before the current request was sent, this method forwards back to the originating request. This effectively ends processing of the current request, so do not call this method before you have finished the necessary business logic!

protected forwardToReferringRequest() : ResponseInterface|null
Internal
Return values
ResponseInterface|null

getErrorFlashMessage()

A template method for displaying custom error flash messages, or to display no flash message at all on errors. Override this to customize the flash message in your action controller.

protected getErrorFlashMessage() : bool|string

Returns either the flash message or "false" if no flash message should be set

Return values
bool|string

getFlashMessageQueue()

todo: As soon as the incoming request contains the compiled plugin namespace, extbase will offer a trait to create a flash message identifier from the current request. Users then should inject the flash message service themselves if needed.

protected getFlashMessageQueue([string|null $identifier = null ]) : FlashMessageQueue
Parameters
$identifier : string|null = null
Internal
Return values
FlashMessageQueue

getFlattenedValidationErrorMessage()

Returns a string with a basic error message about validation failure.

protected getFlattenedValidationErrorMessage() : string

We may add all validation error messages to a log file in the future, but for security reasons (@see #54074) we do not return these here.

Internal
Return values
string

handleArgumentMappingExceptions()

This method processes exceptions that occur due to missing or not found targets or arguments during argument mapping. Based on configuration settings, either a "page not found" response is triggered or the original exception is propagated.

protected handleArgumentMappingExceptions(Exception $exception) : void

Extension authors can override this function to implement additional/custom argument mapping exception handling

Parameters
$exception : Exception

htmlResponse()

Returns a response object with either the given html string or the current rendered view as content.

protected htmlResponse([string|null $html = null ]) : ResponseInterface
Parameters
$html : string|null = null
Return values
ResponseInterface

initializeAction()

Initializes the controller before invoking an action method.

protected initializeAction() : void

Override this method to solve tasks which all actions have in common.

initializeActionMethodArguments()

Implementation of the arguments initialization in the action controller: Automatically registers arguments of the current action

protected initializeActionMethodArguments() : void

Don't override this method - use initializeAction() instead.

Internal
Tags
throws
InvalidArgumentTypeException

initializeArguments()

initializeActionMethodValidators()

Adds the needed validators to the Arguments:

protected initializeActionMethodValidators() : void
  • Validators checking the data type from the param annotation
  • Custom validators specified with validate annotations.
  • Model-based validators (validate annotations in the model)
  • Custom model validator classes
Internal

jsonResponse()

Returns a response object with either the given json string or the current rendered view as content. Mainly to be used for actions / controllers using the JsonView.

protected jsonResponse([string|null $json = null ]) : ResponseInterface
Parameters
$json : string|null = null
Return values
ResponseInterface

mapRequestArgumentsToControllerArguments()

Maps arguments delivered by the request object to the local controller arguments.

Internal

redirect()

Redirects the request to another action and / or controller.

protected redirect(string|null $actionName[, string|null $controllerName = null ][, string|null $extensionName = null ][, array<string|int, mixed>|null $arguments = null ][, int|null $pageUid = null ][, null $_ = null ][, int $statusCode = 303 ]) : ResponseInterface

Redirect will be sent to the client which then performs another request to the new URI.

Parameters
$actionName : string|null

Name of the action to forward to

$controllerName : string|null = null

Unqualified object name of the controller to forward to. If not specified, the current controller is used.

$extensionName : string|null = null

Name of the extension containing the controller to forward to. If not specified, the current extension is assumed.

$arguments : array<string|int, mixed>|null = null

Arguments to pass to the target action

$pageUid : int|null = null

Target page uid. If NULL, the current page uid is used

$_ : null = null

(optional) Unused

$statusCode : int = 303

(optional) The HTTP status code for the redirect. Default is "303 See Other

Return values
ResponseInterface

redirectToUri()

Redirects the web request to another uri.

protected redirectToUri(string|UriInterface $uri[, null $_ = null ][, int $statusCode = 303 ]) : ResponseInterface
Parameters
$uri : string|UriInterface

A string representation of a URI

$_ : null = null

(optional) Unused

$statusCode : int = 303

(optional) The HTTP status code for the redirect. Default is "303 See Other"

Return values
ResponseInterface

renderAssetsForRequest()

Method which initializes assets that should be attached to the response for the given $request, which contains parameters that an override can use to determine which assets to add via PageRenderer.

protected renderAssetsForRequest(RequestInterface $request) : void

This default implementation will attempt to render the sections "HeaderAssets" and "FooterAssets" from the template that is being rendered, inserting the rendered content into either page header or footer, as appropriate. Both sections are optional and can be used one or both in combination.

You can add assets with this method without worrying about duplicates, if for example you do this in a plugin that gets used multiple time on a page.

Parameters
$request : RequestInterface
Internal

resolveActionMethodName()

Resolves and checks the current action method name

protected resolveActionMethodName() : string
Internal
Tags
throws
NoSuchActionException

if the action specified in the request object does not exist (and if there's no default action either).

Return values
string

resolveView()

Prepares a view for the current action.

protected resolveView() : ViewInterface
Internal
Tags
todo

We may want to decide in extbase to go away from the automatic view preparation via processRequest() and this method for actions. We could very well postulate actions should take care of creating "their" view on their own using a ViewFactoryInterface implementation, similar to what is done with request creation already (which needs further work, too), and have a helper in this class to easily create a standard view. This would dissolve the ugly $this->defaultViewObjectName property, which is more a burden than helpful since controllers then need to have an initializeFooAction() just to set this property when different actions want different views. Also, it does not allow actions to have no view prepared at all, for instance when they just want to create a json response by json_encode()'ing stuff. We should look at this in v14, which renders property defaultViewObjectName even more useless.

Return values
ViewInterface
