Deprecation: #98371 - Deprecated Fluid getters¶
See forge#98371
Description¶
Views in a Model-View-Controller (MVC) construct should be data sinks.
Class \TYPO3\CMS\Fluid\View\StandaloneView
violates this concept by
providing some getXY()
methods that allow fetching previously set state.
The Fluid class \TYPO3\CMS\Fluid\Core\Rendering\RenderingContext
is the main object carried around within the rendering chain to keep track
of state. It is the main data object used in view helpers.
As such, StandaloneView
should not allow fetching state since it allows
to be misused to park state, which is primarily a controller concern instead.
To enforce this pattern, the following methods have been marked as deprecated in TYPO3 Core v12 and will be removed in TYPO3 v13:
\TYPO3\CMS\Fluid\View\StandaloneView->getRequest()
\TYPO3\CMS\Fluid\View\StandaloneView->getFormat()
\TYPO3\CMS\Fluid\View\StandaloneView->getTemplatePathAndFilename()
Impact¶
Calling one of the above methods triggers a PHP E_USER_DEPRECATED
level
error.
Affected installations¶
Instances with extensions using one of the above methods.
Migration¶
Do not misuse StandaloneView
as data source. Typically, controllers
should handle and keep track of state like a PSR-7 Request and set or update
view state.
