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

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.

  • Custom validators specified with validate annotations.
  • Model-based validators (validate annotations in the model)
  • Custom model validator classes

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

Parameters

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

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.

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
