how to use "filerenameupload" filter in zend framework2? - forms

Question

i add file element in form class with:
$this->add(array(
'type' => 'Zend\Form\Element\File',
'name' => 'logo_file',
'options' => array(
'label' => 'Select your logo image file:',
),
));
then add filter in model for filtering form data. i use "filerenameupload" filter to upload selected file :
$inputFilter = new InputFilter();
$inputFilter->add($factory->createInput(array(
'name' => 'logo_file',
'required' => false,
'filters' => array(
array('name' => 'filerenameupload',
'options'=>array(
//'target' => "./data/logo.png",
'randomize' => true,
)
),
),
)));
and in controller i call setInputFilter, setData and isValid normally. other elements go filter good, but "logo_file" does not be saved in "./data/logo.png".
in fact "filter" function in "Zend\Filter\File\RenameUpload" class does not be executed.
i use this link :

Someone's trying to solve this problem?

Answer 1

Have you tried using the full name for the Filter?
array(
'name' => 'Zend\Filter\File\RenameUpload'
)
You also need to make sure you add both the files array and the POST data to the form when validating, example:
$postArr = $request->getPost()->toArray();
$fileArr = $this->params()->fromFiles('logo_file');
$formData = array_merge(
$postArr, // $_POST
array('logo_file' => $fileArr['name']) // $_FILE...
);
$importForm->setData($formData);

Try:
Form.php:
public function addElements(){
$this->add(array(
'name' => 'image',
'attributes' => array(
'type' => 'file',
),
'options' => array(
),
));
FormValidator.php
public function getInputFilter()
{
if (!$this->inputFilter) {
$inputFilter = new InputFilter();
$factory = new InputFactory();
$inputFilter->add($factory->createInput(array(
"name" => "image",
"required" => true,
"filters" => array(
array("name" => "StripTags"),
array("name" => "StringTrim"),
array(
"name" => "Zend\Filter\File\RenameUpload",
"options" => array(
"target" => '/home/limonazzo/UPLOADDIR<----------',
"randomize" => true,
"use_upload_name" => true,
"use_upload_extension" => true
)
)
),
"validators" => array(
array(
"name" => "Zend\Validator\File\IsImage",
"break_chain_on_failure" => true,
"options" => array(
),
),
array(
"name" => "Zend\Validator\File\Extension",
"break_chain_on_failure" => true,
"options" => array(
"extension" => "jpg,jpeg,png",
),
),
array(
"name" => "Zend\Validator\File\Size",
"break_chain_on_failure" => true,
"options" => array(
"min" => "1kB",
"max" => "1024kB",
),
),
array(
"name" => "Zend\Validator\File\ImageSize",
"break_chain_on_failure" => true,
"options" => array(
"minWidth" => 10,
"minHeight" => 10,
"maxWidth" => 250,
"maxHeight" => 350,
),
),
),
)));
In controlle.php
$form = new Form();
$formValidator = new FormValidator();
$form->setInputFilter($formValidator->getInputFilter(''));
if ($form->isValid()) {
$data = $form->getData(\Zend\Form\FormInterface::VALUES_AS_ARRAY);
$imgName = $data["image"]["tmp_name"];
