[TYPO3-mvc] 1:n Relation as multiple select?

[g4-lisz at tonarchiv.ch]

Yes this works. Had to do the same a few days ago (see German list):

Your model needs a array property (getter/setter, no TCA), which takes
the selected UIDs from the form.select viewhelper.

E.g.

Model "House" has 1..n "Room"s

Add a house.roomArray as array() to your House model.

In the form viewhelper add this line:

<f:form.select size="5" multiple="multiple" property="roomArr"
options="{rooms}" optionValueField="uid" optionLabelField="name"/>

Your roomArray Getter/Setter have to handle the Uids from/to the array,
like:

        public function getRoomArr() {
                $roomarr = array();
                foreach ($this->rooms as $room)
                        $roomarr[] = $room->getUid();
                return $roomarr;
        }

        public function setRoomArr($roomarr) {
                $roomRepository =
\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('GK\Stdapp\Domain\Repository\RoomRepository');
                $newStorage = 
\TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\CMS\Extbase\Persistence\ObjectStorage');
                foreach($roomarr as $uid)
                       
$newStorage->attach($roomRepository->findByUid($uid));
                $this->setRoom($newStorage);
        }

This worked for me. But maybe there is a more straight forward solution...

Cheers,
Till
