Symfony2 : Multiple Upload File doesn't work

Question

When I select two files, this code doesn't work. I don't know what I'm doing wrong..

This is my controller.

public function createAction()
{
  $router = $this->get('router');
  $request = $this->get('request');
  $description = $request->request->get('description');                                   
  $picturesFromPage = $request->files->all();                                             
  $jsonErrorCreator = $this->get('project_api.create_error_json');
  $nbPictures = count($picturesFromPage);                                                   

  return ($jsonErrorCreator->createErrorJson(101, $nbPictures));
}

In my twig:

<input name="pictures" type='file' multiple='multiple' required>

The Json answers:

{"code":101,"msg":"0 files uploaded","data":1}

Not an answer, but you access Request object like that: createAction(Request $request) — Bartek

If you var_dump count($picturesFromPage) what does it show? — Javad

@Gura I would recommend to set $picturesFromPage = $request->files->get('pictures'); Also you need to put the name of file input in brackets if you want to upload multiple like name="pictures[]" — Javad

@Javad it works! So why $request->files->all() don't do this job? — Gura

The files->all() method returns all form parameters not the submitted value(s). It's better to use files->get() instead so that it will get the value(s) of the parameter you want.
Change it as:

$picturesFromPage = $request->files->get('pictures');

Furthermore, if you want to submit an array of values in your form you need to put their name in bracket as

<input name="pictures[]" type='file' multiple='multiple' required>
