InputFilter "setRequired" not working for html5 multiple - forms

Question

I'm having hard time with a weird behaviour of fileinput.
This is my form:
namespace Frontend\Form;
use NW\Form\Form;
use Zend\InputFilter;
use Zend\Form\Element;
use Zend\ServiceManager\ServiceManager;
use Zend\ServiceManager\ServiceManagerAwareInterface;
class EnrollStructure extends Form implements ServiceManagerAwareInterface
{
protected $sm;
public function __construct($name=null) {
parent::__construct("frmEnrollStructure");
$this->setAttribute("action", "/registrazione_struttura/submit")
->setAttribute('method', 'post')
->setAttribute("id", "iscrizione_struttura")
->setAttribute("class", "form fullpage");
$this->addInputFilter();
}
public function init()
{
$structureFs = $this->sm->get('Structure\Form\Fieldsets\Structure');
$structureFs->setUseAsBaseFieldset(true);
$structureFs->remove("id")
->remove("creationTime")
->remove("latLon");
$file = new Element\File("images");
$file->setAttribute('multiple', true);
$this->add($structureFs)->add($file);
$this->add(array(
'name' => 'submit',
'attributes' => array(
'type' => 'submit',
'value' => 'Iscriviti',
'id' => 'sbmtEnrollStructure',
'class' => 'submit_btn'
),
));
$this->setValidationGroup(
array(
'structure' =>
array(
'companyname',
'vatNumber',
'addressStreet',
'addressZip',
'addressCity',
'addressRegion',
'fax',
'publicPhone',
'publicEmail',
'website',
'status',
'ownerNotes',
'category',
'subcategory',
"facilities",
"agreeOnPolicy",
"agreeOnPrivacy",
"subscribeNewsletter",
"contact" => array("name", "surname", "email", "role", "phone"),
),
"images"
));
}
/**
* Set service manager
*
* #param ServiceManager $serviceManager
*/
public function setServiceManager(ServiceManager $serviceManager)
{
$this->sm = $serviceManager;
}
public function addInputFilter()
{
$inputFilter = new InputFilter\InputFilter();
// File Input
$fileInput = new InputFilter\FileInput('images');
$fileInput->setRequired(true);
$fileInput->getValidatorChain()
->attachByName('filesize', array('max' => "2MB"))
->attachByName('filemimetype', array('mimeType' => 'image/png,image/x-png,image/jpg,image/jpeg'))
->attachByName('fileimagesize', array('maxWidth' => 2048, 'maxHeight' => 2048));
$inputFilter->add($fileInput);
$this->setInputFilter($inputFilter);
}
}
Basically, I mainly use a fieldset which contains most of the data I request to the user, plus a File input field.
This is the Fieldset Structure: (most important parts..)
use Zend\Form\Element;
use Zend\Form\Fieldset;
use Zend\InputFilter\InputFilterProviderInterface;
use Zend\ServiceManager\ServiceManager;
use Zend\ServiceManager\ServiceManagerAwareInterface;
use DoctrineModule\Stdlib\Hydrator\DoctrineObject as DoctrineHydrator;
use Zend\Validator\Identical;
use Zend\Validator\NotEmpty;
use Zend\Validator\Regex;
use Zend\Validator\StringLength;
class Structure extends Fieldset implements InputFilterProviderInterface, ServiceManagerAwareInterface
{
protected $sm;
public function __construct()
{
parent::__construct('structure');
}
public function init()
{
$this->setHydrator(new DoctrineHydrator($this->_entityManager(),'Structure\Entity\Structure'));
$this->setObject($this->sm->getServiceLocator()->get("Structure_Structure"));
$id = new Element\Hidden("id");
$name = new Element\Text("companyname");
$name->setLabel("Ragione Sociale");
...........
}
public function getInputFilterSpecification()
{
return array
(
"id" => array(
"required" => false,
),
"companyname" => array(
"required" => true,
"validators" => array(
array('name' => "NotEmpty", 'options' => array("messages" => array( NotEmpty::IS_EMPTY => "Inserire la ragione sociale")))
),
),
.....
}
}
This is my controller:
public function submitAction()
{
try {
$this->layout("layout/json");
$form = $this->getForm('Frontend\Form\EnrollStructure');
//$form->addInputFilter();
$structure = $this->getServiceLocator()->get("Structure_Structure");
$viewModel = new ViewModel();
$request = $this->getRequest();
if ($request->isPost())
{
$post = array_merge_recursive
(
$request->getPost()->toArray(),
$request->getFiles()->toArray()
);
$form->setData($post);
if ($form->isValid())
{
$structure = $form->getObject();
$contact = $structure->getContact();
$this->getServiceLocator()->get('Structure_ContactService')->save($contact);
$files = $request->getFiles()->toArray();
if(isset($files['images']))
{
$count = 3;
foreach($files['images'] as $pos => $file)
{
$fpath = $this->getServiceLocator()->get('RdnUpload\Container')->upload($file);
if(!empty($fpath))
{
if(--$count ==0) break;
$asset = $this->getServiceLocator()->get("Application_AssetService")->fromDisk($fpath, $file['name']);
$this->getServiceLocator()->get("Application_AssetService")->save($asset);
$structure->addImage($asset);
}
}
}
$this->getServiceLocator()->get('Structure_StructureService')->save($structure);
$retCode = RetCode::success(array("iscrizione_struttura!" => array("form_submit_successfull")), true);
}
else
{
$messages = $form->getMessages();
if(empty($messages))
$retCode = RetCode::error(array("iscrizione_struttura" => array("need_at_least_one_file" => "missing file")), true);
else
$retCode = RetCode::error(array("iscrizione_struttura" => $messages), true);
}
$viewModel->setVariable("retcode", $retCode);
return $viewModel;
}
} catch(Exception $e)
{
throw $e;
}
}
The strange thing is that if i remove from the field "images" the "multiple" attribute everything works fine, causing the form not to validate and i get this message:
[images] => Array
(
[fileUploadFileErrorFileNotFound] => File was not found
)
While, if i set the attribute multiple, and the user does not upload a file i get no error, but the form gets invalidated (this is the reason for this "bad" code in my controller:)
$messages = $form->getMessages();
if(empty($messages))
$retCode = RetCode::error(array("iscrizione_struttura" => array("need_at_least_one_file" => "missing file")), true);
else
$retCode = RetCode::error(array("iscrizione_struttura" => $messages), true);

Answer 1

I found the problem was caused by the Jquery form plugin, without it it works fine. :( In case somebody needs, I think the correct action code can be found here (I haven't tryied it anyway)
