         $form = new MultipleImageForm();
         $form->get('submit')->setValue('Submit');
         $request = $this->getRequest();
         if($request->isPost())
         {
            $nonFile = $request->getPost()->toArray();
            $File    = $this->params()->fromFiles('file');
            $data = array_merge_recursive($request->getPost()->toArray(), $request->getFiles()->toArray());
            //print_r($data); die;
            $form->setData($data);
            if ($form->isValid())

            }
         }
         return array('form' => $form);
    }

表格

public function __construct($name = null)
{
    parent::__construct('stall');
    $this->setAttribute("method","post");
    $this->setAttribute("enctype","multipart/form-data");

    $this->add(array(
        'name' => 'varad',
        'attributes' => array(
            'type'  => 'file',
            'multiple'=>'multiple',
        ),
        'options' => array(
            'label' => 'First Image',
        ),
         'validators' => array(
        'Size'  => array('max' => 10*1024*1024),

        )
    )); 

    $this->add(array(
        'name' => 'test',
        'attributes' => array(
