Feature: #99220 - Add event to modify search results

See forge#99220

Description

A new PSR-14 event \TYPO3\CMS\Backend\Search\Event\ModifyResultItemInLiveSearchEvent is added to allow extension developers to take control over search result items rendered in the backend search.

The event has a public method called getResultItem(), returning the \TYPO3\CMS\Backend\Search\LiveSearch\ResultItem instance of the search result item.

Impact

Search result items may be modified within a custom event listener, e.g. to add custom actions.

Example

use TYPO3\CMS\Core\Localization\LanguageService;

    public function __construct(
        protected readonly IconFactory $iconFactory,

    }

    public function __invoke(ModifyResultItemInLiveSearchEvent $event): void

            return;
        }

        if (($resultItem->getExtraData()['table'] ?? null) === 'tt_content') {

                ->setLabel($this->languageService->sL('LLL:EXT:core/Resources/Private/Language/locallang_mod_web_list.xlf:history'))
                ->setIcon($this->iconFactory->getIcon('actions-document-history-open', Icon::SIZE_SMALL))
                ->setUrl((string)$this->uriBuilder->buildUriFromRoute('record_history', [
                    'element' => $resultItem->getExtraData()['table'] . ':' . $resultItem->getExtraData()['uid']
                ]));
            $resultItem->addAction($showHistoryAction);
        }
