Zend - inputfilter get randomize name - zend-form

Question

Hello I'm trying ZF2 form with an input file.
I have a form with a file input and I want to insert the randomize name into my db.
How I can return the randomized name?
thanks.
This is the simple form class:
class OrdineForm extends Formhttp://stackoverflow.com/questions/ask
public function __construct($name = null)
{
parent::__construct('ordine');
$this->setAttribute('method', 'post');
$this->addElements();
$this->addInputFilter();
}
public function addElements(){
$this->add(array(
'name' => 'pdf',
'attributes' => array(
'type' => 'text',
'disabled' =>'true',
),
'options' => array(
'label' => 'PDF',
),
));
// FILE INPUT
$file = new File('file');
$file
->setLabel('PDF attach')
->setAttributes(array(
'id' => 'file',
));
$this->add($file);
$this->add(array(
'name' => 'submit',
'attributes' => array(
'type' => 'submit',
'value' => 'Add',
'id' => 'submitbutton',
'class' => 'btn btn-success'
),
));
}
public function addInputFilter()
{
$inputFilter = new InputFilter\InputFilter();
$fileInput= new FileInput('file');
$fileInput->setRequired(false);
$fileInput->getFilterChain()->attachByName(
'filerenameupload',
array(
'target' => './public/tmpuploads/',
'randomize' => true,
"UseUploadname" => true,
)
);
$inputFilter->add($fileInput);
$this->setInputFilter($inputFilter);
}
}

After you have validated the form in your controller you can use $form->getData();
there should be a key 'file' as that is what you named your file element. Within that a key 'tmp_name'.
This will be the randomized name.
Eg:
public function uploadfileAction()
{
//get form and filter
$form = $this->getServiceLocator()->get('SomeModule\Form\UploadFileForm');
$filter = $this->getServiceLocator()->get('SomeModule\Form\UploadFileFilter');
$form->setInputFilter($filter->getInputFilter());
if ($this->getRequest()->isPost()) {
//merge files with post
$post = array_merge_recursive(
$this->getRequest()->getPost()->toArray(),
$this->getRequest()->getFiles()->toArray()
);
//set data in form
$form->setData($post);
//check is valid- form data will now contain new name
if ($form->isValid()) {
var_dump($form->getData());
}
}
}
The resulting array dump may look something like this:
array(13) {
["file"]=>
array(5) {
["name"]=>
string(14) "some-pdf.pdf"
["type"]=>
string(24) "application/pdf"
["tmp_name"]=>
string(46) "/public/tmpuploads/new-randomized-name.pdf"
["error"]=>
int(0)
["size"]=>
int(651264)
}
["submit"]=>
string(6) "Submit"
["csrf"]=>
string(32) "4df771bb2fb14e28992a408583745946"
}
You can then just do:
$formData = $form->getData();
$fileNewLocation = $formData['file']['tmp_name'];
//do what you want with $fileNewLocation
