|
|
==========================================
|
|
Deprecation: #90348 - PageLayoutView class
|
|
==========================================
|
|
|
|
See :issue:`90348`
|
|
|
|
Description
|
|
===========
|
|
|
|
The :php:`PageLayoutView` class, which is considered internal API, has been marked as deprecated in favor
|
|
of the new Fluid-based alternative which renders the "page" BE module.
|
|
|
|
|
|
Impact
|
|
======
|
|
|
|
Implementations which depend on :php:`PageLayoutView` should prepare to use the alternative implementation (by overlaying and overriding Fluid templates of EXT:backend).
|
|
|
|
|
|
Affected Installations
|
|
======================
|
|
|
|
* Any site which overrides the :php:`PageLayoutView` class. The overridden class will
|
|
still be instantiated when rendering previews in BE page module - but no methods
|
|
will be called on the instance **unless** they are called by a third party hook subscriber.
|
|
* Any site which depends on PSR-14 events associated with :php:`PageLayoutView` will only
|
|
have those events dispatched if the :php:`fluidBasedPageModule` feature flag is :php:`false`.
|
|
* Affects :php:`\TYPO3\CMS\Backend\View\Event\AfterSectionMarkupGeneratedEvent`.
|
|
* Affects :php:`\TYPO3\CMS\Backend\View\Event\BeforeSectionMarkupGeneratedEvent`.
|
|
|
|
|
|
Migration
|
|
=========
|
|
|
|
Fluid templates can be extended or replaced to render custom header, footer or preview of
|
|
a given :typoscript:`CType`, see feature description for feature :issue:`90348`.
