ZF2 fileupload not required with annotationbuilder - validation

Question

I'm stuck at a problem with ZendFramework 2, annotationbuilder and fileupload.
for at contact form i want user the choice to upload a file.
I got everything to work except the file upload, if there is no file a get the
error:
File was not uploaded
I'm using annotationbuilder to create the form. some annotations is cut out with a space for testing. but did not help.
the Annotation class:
<?php
/**
* #Annotation\Name("message")
* #Annotation\Hydrator("Zend\Stdlib\Hydrator\ObjectProperty")
* #ORM\Entity
* #ORM\Table(name="contact_message")
*/
class Message {

* #Annotation\Exclude()
*
* #ORM\Id
* #ORM\GeneratedValue
* #ORM\Column(type="integer")
* #var integer
*/
private $id;

private $about;

return get_object_vars($this);

?>
and the add Action in my controller:
<?php
use Zend\View\Model\ViewModel;
use Zend\Form\Annotation\AnnotationBuilder;
use Contact\Entity\Contact;
use Contact\Entity\Company;
use Contact\Entity\Message;
use Contact\Controller\EntityUsingController;
class MessageController extends EntityUsingController {
public function addAction(){
$message = new Message();
$builder = new AnnotationBuilder();
$form = $builder->createForm($message);
$form->bind($message);
$request = $this->getRequest();
if ($request->isPost()) {
$form->bind($message);
$requestData = array_merge_recursive((array) $request->getPost(),(array) $request->getFiles());
$form->setData($requestData);
var_dump($request->getFiles());
if ($form->isValid()) {
$em = $this->getEntityManager();
$em->persist($message);
$em->flush();
$this->flashMessenger()->addMessage('Contact Saved');
return $this->redirect()->toRoute('contact');
}
}
return new ViewModel(array(
'form' => $form
));
}
private function storeFile($file){
if (!$this->getConfiguration('fileupload')){
return null;
}
$fileBank = $this->getServiceLocator()->get('FileRepository');
$entity = $fileBank->save('/tmp/myfile.jpg');
}
}
?>
I hope anyone can help my get around this problem.

Answer 1

This seems to be a bug in the annotation builder.
I found a lot of places on the net that confirmed that i should be correct.
so i ended up hacking it by adding the file input after the form was build.
if ($this->getConfiguration('fileupload')){
$companyForm->add(array(
'name' => 'file',
'priority' => 300,
'type' => 'file',
'options' => array(
'label' => 'File:',
),
),array('priority' => 300));
}
checks if the configuration allows for file upload. an extra feature I put in now that I could not set the file upload as an annotation

Answer 2

If you're still interested in another way:
You can try the AllowEmpty annotation:
* #Annotation\AllowEmpty(true)
Or you can try to disable the validator for that field in the controller:
$form->getInputFilter()->remove('file');
