AfterContentHasBeenFetchedEvent
New in version 13.4.2 / 14.0
Using the PSR-14 \TYPO3\,
it is possible to manipulate the page content, which has been fetched by the
page-content data processor,
based on the page layout and corresponding columns configuration.
Example
The event listener class, using the PHP attribute # for
registration, removes some of the fetched page content elements based on
specific field values.
