FileReference helper

This extension implements a child class of FileReference and a helper with some convenience methods to help you creating a new FileReference for your model.

Installation

Install extension and add its static TypoScript template to your template.

Usage

1. Add TCA and model implementation

Add both parts as usual, nothing special here. Example for adding a field named "image":

TCA:

'image' => [
        'label' => 'LLL:my_extension/Resources/Private/Language/locallang_db.xlf:tx_myextension_domain_model_mymodel.image',
        'config' => \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::getFileFieldTCAConfig(
                'image',
                [
                        'maxitems' => 1,
                        'foreign_match_fields' => [
                                'fieldname' => 'image',
                                'tablenames' => 'tx_myextension_domain_model_mymodel',
                                'table_local' => 'sys_file',
                        ],
                ],
                'jpg,jpeg,png'
        )
]

Model:

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

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

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

2. Make use of the helper

In e.g. your controller, you may now use the FileReferenceHelper to move a locally available file to a specific location, returning the resulting FileReference.

Example of handling an upload:

$myObject = $this->myRepository->findOneByUid($uid);

if ($_FILES['image'] && $_FILES['image']['size'] > 0) {
        $tmpName = $_FILES['image']['name'];
        $tmpFile = $_FILES['image']['tmp_name'];

        // Get the helper itself.
        $fileReferenceHelper = $this->objectManager->get(\Akb\FileReference\Helper\FileReferenceHelper::class);

        // Just a convenience method to make sure, it won't result in multiple images
        // where only one is allowed
        $fileReferenceHelper->removeFileReferenceIfEmpty($myObject, "image");

        // 3rd parameter must be a folder within your default storage.
        $fileReference = $fileReferenceHelper->fileToFileReference($tmpFile, $tmpName, "images");

        // As you now have a valid file reference, just add it.
        $myObject->setImage($fileReference);
}

Notes

• Storage handling defaults to your default storage and has no special handling for sub folders.
