Since I have a custom jQuery plugin for transferring files to my symfony2 webapp, I am looking for ways to handle this download in the controller.
The standard (non-ajax) file upload that I currently have (and which works fine for synchronous calls) looks like this:
Excerpt for controller
... $entity = new Image(); $request = $this->getRequest(); $form = $this->createForm(new ImageType($createAction), $entity); $form->bind($request); // <-- Find a way to make this connection manually?! //check that a file was chosen $fileExists = isset($entity->file); if ( ($form->isValid()) && ($fileExists) ) { $em = $this->getDoctrine()->getManager(); $em->persist($entity); $em->flush(); } ...
Type of form : the form just takes the file and name:
class ImageType extends AbstractType { ... public function buildForm(FormBuilderInterface $builder, array $options) { $createAction = $this->createAction; if ($createAction) { $builder ->add('file') ; } $builder ->add('name', 'text', array('label' => 'Namn')) ; } ... }
As I understand it (or, in other words, DO NOT VIEW), the system for downloading files with symfony2 and the doctrine there is quite a lot of magic passing under the hood during this call
$form->bind($request);
For example, if I skip this bind () and instead try to create an Image object manually, like this ...
$request = $this->getRequest(); $parent = $request->request->get('parent'); $file = $request->request->get('file1'); $name = $request->request->get('name'); $entity->setName( $name ); $entity->setFile( $file ); $entity->setFolder( null );
... I find that it doesn't even have setFile (), so it will take care of something else. Here is what the Image Object is :
