问题
Actually I'm developing a simple file uploader.
In the ImageUploader.php file I define the getInputFilter function, all works unless I try to add a File\MimeType validator:
<?php
namespace Admin\Model;
use Zend\InputFilter\Factory as InputFactory;
use Zend\InputFilter\InputFilter;
use Zend\InputFilter\InputFilterAwareInterface;
use Zend\InputFilter\InputFilterInterface;
use Zend\Validator\File\MimeType; //tried also with use Zend\Validator\File;
[...]
public function getInputFilter()
{
[...]
$inputFilter->add($factory->createInput(array(
'name' => 'image',
'required' => true,
'validators' => array(
array(
'name' => 'MimeType', //tried also with File\MimeType
'options' => array(
'mimeType' => array('image/jpeg'),
),
),
),
)));
[...]
}
What's the correct way to define a File\Validator\MimeType?
Thank you in advance.

Here is a sample from my project with a couple of other useful features (renaming for example):
use Zend\File\Transfer\Adapter\Http,
Zend\Validator\File\Size,
Zend\Validator\File\IsImage;
[...]
public function editAction() {
[...]
if ($request->isPost()) {
$params = $this->params()->fromPost();
$files = $this->params()->fromFiles();
$images = array();
if(!empty($files['main_image']['name'])) $images['main_image'] = $files['main_image']['name'];
if(!empty($files['detailed_image']['name'])) $images['detailed_image'] = $files['detailed_image']['name'];
if(!empty($images)) {
$adapter = new Http();
$size = new Size(array('max'=>1000000));
$is_image = new IsImage();
$image_errors = array();
foreach ($images as $field => $filename) {
$adapter->setValidators(array($size,$is_image), $filename);
if (!$adapter->isValid($filename)) {
$adapter_errors = $adapter->getMessages();
$errors = array();
foreach($adapter_errors as $key=>$row) {
$errors[] = $row;
}
if(!empty($errors)) {
array_push($image_errors, $errors);
$form->setMessages(array($field => $errors));
}
} else {
$adapter->setDestination(IMAGES_PATH);
$fileinfo = $adapter->getFileInfo();
preg_match('/.+\/(.+)/', $fileinfo[$field]['type'], $matches);
$extension = $matches[1];
$old_filename = $item->__get($field);
$new_filename = $item->id.'_'.$field.'.'.$extension;
$adapter->addFilter('File\Rename',
array(
'target' => IMAGES_PATH.$new_filename,
'overwrite' => true,
)
);
if($adapter->receive($fileinfo[$field]['name'])) {
if(!empty($old_filename) && $old_filename != $new_filename &&
file_exists(IMAGES_PATH.$old_filename)) {
unlink(IMAGES_PATH.$old_filename);
}
$params[$field] = $new_filename;
}
}
}
}
}
[...]
}
[...]
The code however could be refactored to move the logic to some lib or model.

Not sure which version you are using now but with Zendframework 2.4 you can now do this. Hope this helps.
public function getInputFilter()
{
if (!$this->inputFilter) {
$inputFilter = new InputFilter();
$inputFilter->add(array(
'name' => 'fileupload',
'required' => true,
'allow_empty' => false,
'filters' => array(
array('name' => 'StripTags'),
array('name' => 'StringTrim'),
),
'validators' => array(
array(
'name' => 'Zend\Validator\File\UploadFile',
'name' => 'Zend\Validator\File\MimeType',
'options' => array(
'mimeType' => 'audio, video, image',
),
),
),
));
$this->inputFilter = $inputFilter;
}
return $this->inputFilter;
}
