Not able to get the filenames of uploaded files in symfony2 - php

Question

I have followed Multiple file upload with Symfony2 and created a entity
/*
* #ORM\HasLifecycleCallbacks
* #ORM\Entity(repositoryClass="Repair\StoreBundle\Entity\attachmentsRepository")
*/
class attachments
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #Assert\File(maxSize="6000000")
* #ORM\Column(name="files", type="array", length=255, nullable=true)
*/
private $files=array();
/**
* Get id
*
* #return integer
*/
public function getId() {
return $this->id;
}
/**
* Set files
* #param object $files
*
* #return attachments
*/
public function setFiles($files) {
$this->files = $files;
}
/**
* Get files
*
* #return object
*/
public function getFiles() {
return $this->files;
}
public function __construct() {
$files = array();
}
public function uploadFiles() {
// the files property can be empty if the field is not required
if (null === $this->files) {
return;
}
if (!$this->id) {
$this->files->move($this->getTmpUploadRootDir(), $this->files->getClientOriginalName());
} else {
$this->files->move($this->getUploadRootDir(), $this->files->getClientOriginalName());
}
$this->setFiles($this->files->getClientOriginalName());
}
public function getAbsolutePath() {
return null === $this->path
? null
: $this->getUploadRootDir() . DIRECTORY_SEPARATOR . $this->path;
}
public function getWebPath() {
return null === $this->path
? null
: $this->getUploadDir() . DIRECTORY_SEPARATOR . $this->path;
}
protected function getUploadRootDir() {
return __DIR__ . '/../../../../web/'. $this->getUploadDir();
}
protected function getUploadDir() {
return 'uploads/';
}
}
I have a controller which has the folowing code
class uploadController extends Controller
{
public function uploadAction(Request $request) {
$id= $_GET['id'];
$user = new attachments();
$form = $this->createFormBuilder($user)->add('files','file',array("attr"=>array("multiple" =>"multiple",)))->getForm();
$formView = $form->createView();
$formView->getChild('files')->set('full_name','form[file][]');
if ($request->getMethod() == 'POST') {
$em = $this->getDoctrine()->getManager();
$form->bind($request);
$files = $form["files"]->getFilenames();
$user->uploadFiles(); //--here iam not able to get te file names in order to send to the upload function.upload files is returning null values
}
}
}
the controller is not able to get the filenames that is uploded by the uder from the view.it is returning null values when i send to the upload function in entity

I think you should read the Documentation about File Upload again. You are correctly using the annotation #ORM\HasLifecycleCallbacks but your code is missing the right annotations for the methods. You can use the #ORM\PostPersist() and #ORM\PostUpdate() annotations to call the upload() function automatically after the request was validated and the object was persisted. Also I would suggest using an entity for each file and creating a OneToMany relation. This will make it more easy and logical to store your files correctly.
