zf2 how to upload files, more than 1 file - php

Question

I refer to http://samsonasik.wordpress.com/2012/08/31/zend-framework-2-creating-upload-form-file-validation/ and follow this, I can upload 1 file successfully by using rename filter in ZF2.
However when I use this way to upload 2 files, it goes wrong. I paste my code as following:
$this->add(array(
'name' => 'bigpicture',
'attributes' => array(
'type' => 'file'
),
'options' => array(
'label' => 'Big Pic'
)
));
$this->add(array(
'name' => 'smallpicture',
'attributes' => array(
'type' => 'file'
),
'options' => array(
'label' => 'Small Pic'
)
));
<div class="row"><?php echo $this->formRow($form->get('smallpicture')) ?></div>
<div class="row"><?php echo $this->formRow($form->get('bigpicture')) ?></div>
$data = array_merge(
$request->getPost()->toArray(),
$request->getFiles()->toArray()
);
$form->setData($data);
if ($form->isValid()) {
$product->exchangeArray($form->getData());
$picid = $this->getProductTable()->saveProduct($product);
$pathstr = $this->md5path($picid);
$this->folder('public/images/product/'.$pathstr);
//move_uploaded_file($data['smallpicture']['tmp_name'], 'public/images/product/'.$pathstr.'/'.$picid.'_small.jpg');
//move_uploaded_file($data['bigpicture']['tmp_name'], 'public/images/product/'.$pathstr.'/'.$picid.'_big.jpg');
$fileadaptersmall = new \Zend\File\Transfer\Adapter\Http();
$fileadaptersmall->addFilter('File\Rename',array(
'source' => $data['smallpicture']['tmp_name'],
'target' => 'public/images/product/'.$pathstr.'/'.$picid.'_small.jpg',
'overwrite' => true
));
$fileadaptersmall->receive();
$fileadapterbig = new \Zend\File\Transfer\Adapter\Http();
$fileadapterbig->addFilter('File\Rename',array(
'source' => $data['bigpicture']['tmp_name'],
'target' => 'public/images/product/'.$pathstr.'/'.$picid.'_big.jpg',
'overwrite' => true
));
$fileadapterbig->receive();
}
the above are form,view,action.
using this way, only the small picture uploaed successfully. the big picture goes wrong.
a warning flashed like the following:
Warning:move_uploaded_file(C:\WINDOWS\TMP\small.jpg):failed to open stream:Invalid argument in
E:\myproject\vendor\zendframework\zendframework\library\zend\file\transfer\adapter\http.php

Who can tell me how to upload more than 1 file in this way. you know, the rename filter way similar to above. thanks.

Answer 1

I ran into the same problem with a site i did. The solution was to do the renaming in the controller itself by getting all the images and then stepping through them.
if ($file->isUploaded()) {
$pInfo = pathinfo($file->getFileName());
$time = uniqid();
$newName = $pName . '-' . $type . '-' . $time . '.' . $pInfo['extension'];
$file->addFilter('Rename', array('target' => $newName));
$file->receive();
}
Hope this helps point you in the right direction.

Answer 2

I encountered the same problem and i managed to make it work using the below code;
$folder = 'YOUR DIR';
$adapter = new \Zend\File\Transfer\Adapter\Http();
$adapter->setDestination($folder);
foreach ($adapter->getFileInfo() as $info) {
$originalFileName = $info['name'];
if ($adapter->receive($originalFileName)) {
$newFilePath = $folder . '/' . $newFileName;
$adapter->addFilter('Rename', array('target' => $newFilePath,
'overwrite' => true));
}
}
