I've got a problem I can't find any documentation or solution for.

I've created a TYPO3 extension with a List and Detail View, everything works fine. Now I want to add some Input Fields above the List view, to let Site-Visitors Filter the List view.

How is this done? I'm sure I have to add a Fluid Form above the List View and handle this in Controller?

At the moment my Controller and Repo looks like this:

Controller:

/**
 * EventController
 */
class EventController extends TYPO3CMSExtbaseMvcControllerActionController


 /**
 * eventRepository
 * 
 * @var AlromaDsEventcalendarDomainRepositoryEventRepository
 * @inject
 */
 protected $eventRepository = null;

 /**
 * action list
 * 
 * @return void
 */
 public function listAction()
 
 $events = $this->eventRepository->findAll();
 $this->view->assign('events', $events);
 

 /**
 * action show
 * 
 * @param AlromaDsEventcalendarDomainModelEvent $event
 * @return void
 */
 public function showAction(AlromaDsEventcalendarDomainModelEvent $event)
 
 $this->view->assign('event', $event);
 

 /**
 * action frontpage
 * 
 * @return void
 */
 public function frontpageAction()
 
 $events = $this->eventRepository->findAll();
 $this->view->assign('events', $events);
 

Repo:

class EventRepository extends TYPO3CMSExtbasePersistenceRepository


 // Order by BE sorting
 protected $defaultOrderings = [
 'highlight' => TYPO3CMSExtbasePersistenceQueryInterface::ORDER_DESCENDING,
 'start' => TYPO3CMSExtbasePersistenceQueryInterface::ORDER_ASCENDING
];

To be more specific:
I want a User to have a Field, he can type some Keyword and I want to search it at my "Text" Database-Column of my Extension. If Keyword is found at any Text, show only the Article, that fits. Same for Date Parameter.

The most basic way is for server-side filtering:

• create a form with an input for the query string to search for


• Fetch the argument in your Controller


• Filter your DB query by $query->like

Some code examples:

The form with an input for the argument "querystring"

<f:form action="list">
 <f:form.textfield name="querystring" value="" />
</f:form>

Get the argument in your action:

if ($this->request->hasArgument('querystring')) 
 $querystring = $this->request->getArgument('querystring');
 $events = $this->repository->findAll($querystring);

Filter your DB query in your repository (extend your findAll method or write a new method):

public function findAll($querystring = '') 
 $query = $this->createQuery();
 if ($querystring) 
 $query->matching(
 $query->like('property_to_search_in', '%'.$querystring.'%')
 );
 
 return $query->execute();

If it's not too much content, I'd rather output search tags (data- attributes) for all content and use javascript for filtering. Otherwise you'd need the page to reload just for displaying a subset of content already loaded for the client. Also it wouldn't feel smooth.
