Extbase - File Abstraction Layer (FAL)

Allgemein Dateien mit Extbase Handeln

In general, you should be able to call getOriginalResource() on a \TYPO3\CMS\Extbase\Domain\Model\FileReference object. For more concrete examples, either refer to the doc links or have a look at the wiki for a example handling FileReferences.

Beispiel File Referenz dynamisch erzeugen

http://www.typo3tiger.de/blog/post/extbase-fal-filereference-im-controller-erzeugen.html

Dynamisch bedeutet hier, dass nach dem Upload dynamisch eine FAL FileReference zu einem Objekt im Controller erzeugt wird. Somit kann man die neue Datei auch gleich einem vorhandenen oder neu erstellten Objekt zuordnen.

Allgemeines Vorgehen:

• Erweitern der Klasse FileReference
• TCA Konfiguration vervollständigen
• Parameter an TCA übergeben (Methode getFileFieldTCAConfig mit dem Parameter foreign_match_fields

Achtung: Grund für so manche Verwirrung ist, dass TYPO3 zwei unterschiedliche FileReference-Klassen liefert: Das Extbase Model \TYPO3\CMS\Extbase\Domain\Model\FileReference sowie das Core Model \TYPO3\CMS\Core\Resource\FileReference

Extbase Model (FileReference)

namespace Vendor\Ext\Domain\Model;

/**
 * Class FileReference
 */
class FileReference extends \TYPO3\CMS\Extbase\Domain\Model\FileReference {

    /**
     * uid of a sys_file
     *
     * @var integer
     */
    protected $originalFileIdentifier;

    /**
     * setOriginalResource
     *
     * @param \TYPO3\CMS\Core\Resource\FileReference $originalResource
     * @return void
     */
    public function setOriginalResource(\TYPO3\CMS\Core\Resource\FileReference $originalResource) {
        $this->originalResource = $originalResource;
        $this->originalFileIdentifier = (int)$originalResource->getOriginalFile()->getUid();
    }

    /**
     * setFile
     *
     * @param \TYPO3\CMS\Core\Resource\File $falFile
     * @return void
     */
    public function setFile(\TYPO3\CMS\Core\Resource\File $falFile) {
        $this->originalFileIdentifier = (int)$falFile->getUid();
    }

}

Extbase Model (Person)

namespace Vendor\Ext\Domain\Model;

/**
 * Class Person
 */
class Person extends \TYPO3\CMS\Extbase\DomainObject\AbstractEntity {

    /**
     * title
     *
     * @var string
     */
    protected $title = '';

    /**
     * image
     *
     * @var \TYPO3\CMS\Extbase\Domain\Model\FileReference
     */
    protected $image = NULL;

    /**
     * Returns the title
     *
     * @return string $title
     */
    public function getTitle() {
        return $this->title;
    }

    /**
     * Sets the title
     *
     * @param string $title
     * @return void
     */
    public function setTitle($title) {
        $this->title = $title;
    }

    /**
     * Returns the image
     *
     * @return \TYPO3\CMS\Extbase\Domain\Model\FileReference $image
     */
    public function getImage() {
        return $this->image;
    }

    /**
     * Sets the image
     *
     * @param \TYPO3\CMS\Extbase\Domain\Model\FileReference $image
     * @return void
     */
    public function setImage(\TYPO3\CMS\Extbase\Domain\Model\FileReference $image) {
        $this->image = $image;
    }

}

Extbase Controller (Person)

namespace Vendor\Ext\Domain\Model;

/**
 * Class PersonController
 */
class PersonController  extends \TYPO3\CMS\Extbase\Mvc\Controller\ActionController {

   /**
    * personRepository
    *
    * @var \Vendor\Ext\Domain\Repository\PersonRepository
    * @inject
    */
    protected $personRepository;

   /**
    * pesistenceManager - not neccessary since 6.2
    *
    * @var \TYPO3\CMS\Extbase\Persistence\Generic\PersistenceManager
    * @inject
    */
    protected $persistenceManager;

    /**
     * Action addImage
     *
     * @param \Vendor\Ext\Domain\Model\Person $person
     * @return void
     */
    public function AddImageAction(\Vendor\Ext\Domain\Model\Person $person) {

        $storageRepository = $this->objectManager->get('TYPO3\\CMS\\Core\\Resource\\StorageRepository');
        $storage = $storageRepository->findByUid('1');
        $targetFolder = $storage->createFolder('path/to/target_folder');
        $originalFilePath = '/tmp/tempfile.png';
        $newFileName = 'myfile123.png';

        if (file_exists($originalFilePath)) {
            $movedNewFile = $storage->addFile($originalFilePath, $targetFolder, $newFileName);
            $newFileReference = $this->objectManager->get('Vendor\\Ext\\Domain\\Model\\FileReference');
            $newFileReference->setFile($movedNewFile);
            $person->setImage($newFileReference);
        }

        $this->personRepository->update($person);
        // Not neccessary since 6.2
        $this->persistenceManager->persistAll();

    }

}

TCA Konfiguration (Person)

'image' => array(
	'exclude' => 1,
	'label' => 'LLL:EXT:ext/Resources/Private/Language/locallang_db.xlf:tx_ext_domain_model_person.image',
	'config' => \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::getFileFieldTCAConfig(
		'image',
		array(
			'maxitems' => 6,
			'foreign_match_fields' => array(
				'fieldname' => 'image',
				'tablenames' => 'tx_ext_domain_model_person',
				'table_local' => 'sys_file',
			),
		),
		$GLOBALS['TYPO3_CONF_VARS']['GFX']['imagefile_ext']
	),
),

Typoscript Konfiguration

config.tx_extbase {
	persistence {
		classes {
			Vendor\Ext\Domain\Model\FileReference {
				mapping {
					tableName = sys_file_reference
					columns {
						uid_local.mapOnProperty = originalFileIdentifier
					}
				}
			}
		}
		objects {
			TYPO3\CMS\Extbase\Domain\Model\FileReference.className = Vendor\Ext\Domain\Model\FileReference
		}
		updateReferenceIndex = 1
	}
}

Upload Beispiel - Reusable Code

Um wiederverwendbar für alle Controller zu sein, darf der Code nicht im Controller sein. Dann wirds aber komplizierter. Hier ein Beispiel wie es geht:
