SonataMediaBundle - How to use custom file input

Question

I have a kind of scavenger hunt project in which I am using AngularJS to manage the different questions it may contain. These questions are of different types. Therefore, some may include a file input and some may not. In this project, I am also using Symfony and SonataMediaBundle to manage my files and my images.

Since my html model (mostly my forms) can change depending on the actions of the user, I cannot use Symfony's built-in tool to produce forms. Therefore, all my forms are custom made. This gives me a problem with SonataMediaBundle, when I want some files to be uploaded. If a user selects a file, this file will be sent via POST to a method in the controller, when the form gets sent. Therefore, I want to send this received file to SonataMediaBundle so that it can manage it, but I haven't found anywhere in the documentation how to do such a thing.

Theoretically, it is really simple. In my controller, when I get a file input, I want to let SonataMedia manage the upload (that is the copy to the proper location, etc...) and I have no clue on how I should do that.

Using symfony2 and not utilizing its benefits you are doing a big mistake you should built your app properly but as far as concerned to your question nothing is bounded by symfony but its on your own how you use it.You can get the sonata media manager service from the container and you have to manually set the all the required setters for the media manager and you have to manually work for the validations like file size ,file mimetype etc. Below is the demo how you can store the file in the sonata media bundle

/* Before class use these*/
use Symfony\Component\HttpFoundation\File\File;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Application\Sonata\MediaBundle\Entity\Media;

public function uploadAction()
{

$file = $this->get('request')->files->get('filefieldname');

    if (!$file instanceof UploadedFile || !$file->isValid()) {
        return new Response(json_encode(array(
            'event' => 'uploader:error',
            'data'  => array(
                'message' => 'Missing file.',
            ),
        )));
    }

/* validate max min size for the file */
/* validate mime type for the file */
/* Get sonata media manager service from container    */ 
$mediaManager = $this->container->get('sonata.media.manager.media');
/* create new instance of sonata media class in my case entity is located at 
* Application\Sonata\MediaBundle\Entity\Media 
*/
$media = new Media();
$media->setBinaryContent($file);
$media->setContext('default'); 
$ImagemimeTypes = array('image/jpeg', 'image/png');
$FilemimeTypes = array('application/vnd.openxmlformats-officedocument.wordprocessingml.document',
    'application/msword', 'application/pdf', 'application/x-pdf');
if (in_array($file->getMimeType(), $FilemimeTypes)) {
    $media->setProviderName('sonata.media.provider.file');
}
if (in_array($file->getMimeType(), $ImagemimeTypes)) {
    $media->setProviderName('sonata.media.provider.image');
}
 /*If you have other providers in your app like vimeo /dailymotion etc
 then do set here i have shown you the demo for adding image/file in sonata media */
/*other setters if you want to set like enabled/disable etc*/
 $mediaManager->save($media);
// end function
}

But once again there will be alot of rework you have to do which symfony already provides you the ease for
