UploadField on Frontendform

Hi there,

it seems that the UploadField isn't working correctly on the Frontendforms.

I will show some code and give Explanation afterwards:

// Add Form inside Controller
public function MitarbeiterAddForm(){

$data = Session::get("");

$avatarField = new UploadField('Avatar', 'Mitarbeiter Photo');
$avatarField->allowedExtensions = array('jpg', 'gif', 'png');
//print_r($avatarField->getAttributes()); die();

// Create fields
$fields = new FieldList(
new TextField('Name', 'Name'),

// Create actions
$actions = new FieldList(
new FormAction('doAdd', 'Mitarbeiter anlegen')

$requiredFields = new RequiredFields(

$form = new Form($this, 'MitarbeiterAddForm', $fields, $actions, $requiredFields);

return $form;

public function doAdd($data, $form){

$errors = false;

if($Mitarbeiter = DataObject::get_one('Mitarbeiter', "Name='".Convert::raw2sql($data['Name'])."'")){
$form->addErrorMessage('Name', 'Ein Mitarbeiter mit diesem namen existiert bereits.', 'bad');
$errors = true;

Session::set("", $data);
return $this->redirectBack();

$o_Mitarbeiter = new Mitarbeiter();


// return Director::redirect($this->URLSegment.'/profile');
// We use Email Verified Member
return $this->redirect('mitarbeiter01/all');

    * Show the registration form
   public function all(){

$tmpPage = new Page();
$tmpPage->Title = 'Mitarbeiter';
$tmpPage->URLSegment = self::$url_segment;
$tmpPage->ID = -1; // Set the page ID to -1 so we dont get the top level pages as its children
$controller = new BaseController01($tmpPage);

// WebApps
if(!isset($_GET['start']) || !is_numeric($_GET['start']) || (int)$_GET['start'] < 1) $_GET['start'] = 0;
//$CurrentWebApps = Member::currentUser()->WebApps()->getRange((int)$_GET['start'], 10);

$customisedController = $controller->customise(array(
'Title' => 'Mitarbeiter',
'Content' => "<p>Mitarbeiter Liste</p>",
"Form" => $this->MitarbeiterAddForm(),
"Mitarbeiter" => DataObject::get('Mitarbeiter', '', '', '', (int)$_GET['start'].", 10")
return $customisedController->renderWith(array('MitarbeiterController_all', 'MitarbeiterController0, 'Page', $this->owner->stat('template_main'), 'ContentController'));

I use a Controller without the Pageobject (with its routes set up by routes.yml).
This controller has an AddForm (as you can see) where I want to add "Miitarbeiter" to the System.

The Mitarbeiter has a name ($db) and an Avatar ($has_one, 'Avatar' => 'Image');

On Silverstripe 2.3.x/2.4.x in was able to use SimpleImageFiled in these cases.
On SS3 SimpleImageFiled is marked as deprecated, so I tried with UploadField.

First question, how can I customize UploadField, to hide the "From Files" Button.

If I drag'n'drop or Upload a File from Computer, The Thumbnail is shown within my Form. But when I set the Avatar Field to be required, it returns the warning on Formsubmit, that the field isn't filled.
Also, the Image ID is not written into the "Mitarbeiter"-Object that was added.

Is this a Bug or am I missing something.
