multi picture upload in zend framework, how to? - php

Question

i have an issue with uploading multiple files to disk. here is my code.
i have a request with 2 pictures that gets sent to a upload function. the 2 pictures are in a var called $multiUpload
$folderPath = '/var/www/';
if (is_array($multiUpload)){
$file = array();
$filename = array();
foreach($multiUpload as $key=>$val){
// get the file extension
$file[] = explode('.',$val);
// create custom file name
$filename[] = time().'.'.$file[$key][1];
//send to the upload function
$this->uploadToDisk($folderPath, $filename[$key]);
// sleep 1 sec so that the pic names will be different
sleep(1);
}
return $filename;
}
public function uploadToDisk($folderPath, $filename)
{
$adapter = new Zend_File_Transfer_Adapter_Http();
$adapter->setDestination($folderPath);
$adapter->addFilter( 'Rename',array(
'target' => $folderPath."/".$filename,
'overwrite' => true
) );
if ($adapter->receive()) {
$message = "success";
} else {
$message = "fail";
}
return $message;
}
this will return
Array
(
[0] => Array
(
[0] => 1332977938.jpg
[1] => 1332977939.jpg
)
)
but only array[0][0] or 1332977938.jpg will actually get saves to the disk.
Why are they now both get saved? wired
any ideas?

Answer 1

I suspect the second call to uploadToDisk is returning fail because you can only call Zend_File_Transfer_Adapter_Http::receive() once for each file. Since you are not specifying a file when calling receive, it is receiving all of the files the first time you call uploadToDisk and subsequently is failing with a File Upload Attack error.
Here is some code you can try. This tries to receive each file individually and then save them one at a time with each call to uploadToDisk.
A few notes about the code:
The first parameter to uploadToDisk ($val) may need to be changed as I am not sure what the original values are. It should correspond to one of the element names used for the file upload (See Zend_File_Transfer_Adapter_Http::getFileInfo()) for a list of the files.
I changed the method for generating a unique filename so you don't have to sleep(1)
Zend_File_Transfer_Adapter_Abstract::setDestination() is deprecated and will go away in the future. Instead, just use the Rename filter. When using Rename, setDestination() has no effect.
And here it is...
<?php
$folderPath = '/var/www/';
if (is_array($multiUpload)){
$filenames = array();
foreach($multiUpload as $key => $val){
// get the file extension
$ext = explode('.', $val);
$ext = $ext[sizeof($ext) - 1];
// create custom file name
do {
$filename = uniqid(time()) . '.' . $ext;
$diskPath = $folderPath . $filename;
} while (file_exists($diskPath));
$filenames[$key] = $filename;
//send to the upload function
// $val is the file to receive, $diskPath is where it will be moved to
$this->uploadToDisk($val, $diskPath);
}
return $filename;
}
public function uploadToDisk($file, $filename)
{
// create the transfer adapter
// note that setDestination is deprecated, instead use the Rename filter
$adapter = new Zend_File_Transfer_Adapter_Http();
$adapter->addFilter('Rename', array(
'target' => $filename,
'overwrite' => true
));
// try to receive one file
if ($adapter->receive($file)) {
$message = "success";
} else {
$message = "fail";
}
return $message;
}
