'required' => true,
))
);
$inputFilter->add(array(
'name' => 'name',
'required' => true,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'StringLength',

$this->inputFilter = $inputFilter;
}
return $this->inputFilter;
}
And
public function exchangeArray($data){
$this->id = (isset($data['id']))?$data['id']:null;
//// image////
if(!empty($data['image'])) {
if(is_array($data['image'])) {
$this->image = str_replace("./public/tmpuploads/", "",
$data['image']['tmp_name']);
} else {
$this->image = $data['image'];
}
} else {
$data['image'] = null;
}
$this->name = (isset($data['name']))?$data['name']:null;
$this->department = (isset($data['department']))?$data['department']:null;
$this->marks = (isset($data['marks']))?$data['marks']:null;
}
public function getArrayCopy() {
return get_object_vars($this);
}
my Student Form-
StudentForm.php
namespace Student\Form;
use Zend\InputFilter;
use Zend\Form\Form;
use Zend\Form\Element;
class StudentForm extends Form {
public function __construct($name = null, $options = array())
{
parent::__construct($name, $options);
$this->addElements();
$this->setInputFilter($this->createInputFilter());
}
public function addElements()
{
$image = new Element\File('image');
$image->setLabel('Avatar Image Upload')
->setAttribute('id', 'image-file')
->setAttribute('multiple', true);
$this->add($image);
$name = new Element\Text('name');
$name->setLabel('Name');
$this->add($name);
$department = new Element\Text('department');
$department->setLabel('Department');
$this->add($department);
$marks = new Element\Text('marks');
$marks->setLabel('Marks');
$this->add($marks);
}
public function createInputFilter()
{
$inputFilter = new InputFilter\InputFilter();
// File Input
$image = new InputFilter\FileInput('image');
$image->setRequired(true);
$image->getFilterChain()->attachByName(
'filerenameupload',
array(
'target' => './public/tmpuploads/',
'overwrite' => true,
'use_upload_name' => true,
)
);
$inputFilter->add($image);
// Text Input
$name = new InputFilter\Input('name');
$name->setRequired(true);
$inputFilter->add($name);
// Text Input
$department = new InputFilter\Input('department');
$department->setRequired(true);
$inputFilter->add($department);
// Text Input
$marks = new InputFilter\Input('marks');
$marks->setRequired(true);
$inputFilter->add($marks);
return $inputFilter;
}
}

Answer 1

As i understand your code you have to first upload image and then you have to make comma separated string like this
its only example code
$imageString = '';
for($i=0; $i<count($_FILES['file']['name']); $i++){
$extension = explode('.', basename( $_FILES['file']['name'][$i]));
$imageName = md5(uniqid()) . "." . $extension[count($extension)-1];
$path = $path . $imageName;
if(move_uploaded_file($_FILES['file']['tmp_name'][$i], $path )) {
$imageString .= $imageName.", ";
} else{
echo "Error in Upload";
}
}
$imageName = rtrim($imageName,", ");
// now you can use imageName in insert query.
