ModifyResultItemInLiveSearchEvent¶
New in version 12.2.
The PSR-14 event \TYPO3\CMS\Backend\Search\Event\ModifyResultItemInLiveSearchEvent
is available to allow extension developers to take control over search result
items rendered in the backend search.
Example¶
Warning
Some code in this example is experimental API and may change until TYPO3 v12 LTS.
Registration of the event listener in the extension's Services.yaml:
EXT:my_extension/Configuration/Services.yaml¶
