Get Value From Javascript

Hi I am using `dropdown.js' to upload image to a user profile image.

I need to get the image's path I have uploaded, then pass it to laravel and insert it to the current user image_path column record.

Controller:

  public function index()
{
  return view('dropzone_demo');
}

public function uploadFiles()
{

  $message="Profile Image Created";
  $input = Input::all();

  $rules = array(
      'file' => 'image|max:3000',
  );

  $validation = Validator::make($input, $rules);

  if ($validation->fails()) {
      return Response::make($validation->errors->first(), 400);
  }

  $destinationPath = 'uploads'; // upload path: public/uploads
  $extension = Input::file('file')->getClientOriginalExtension(); // getting file extension
  $fileName = mt_rand(11111, 99999) . '.' . $extension; // renameing image
  $upload_success = Input::file('file')->move($destinationPath, $fileName); // uploading file to given path

  if ($upload_success) {
      return Response::json('success', 200);
  } else {
      return Response::json('error', 400);
  }

}

View:

<div class="container">
                <div class="dropzone" id="dropzoneFileUpload">
                </div>
                <button type="button" id="uploadPhoto">Upload Photo</button>

            </div>


          <script type="text/javascript">
              // Since we're using Juery to initialize Dropzone, we Set autoDiscover to false,so that dropzone object is not initialized twice.
              // So we only initialize it here: var myDropzone

                Dropzone.autoDiscover = false;
                // dropzone should load when the DOM is completely loaded
                jQuery(document).ready(function(){



                   var myDropzone = new Dropzone("div#dropzoneFileUpload", {
                       url: "{{action('DropzoneController@uploadFiles')}}",
                       maxFilesize: 2, // MB
                           maxFiles: 1,
                           addRemoveLinks: true,
                       autoProcessQueue:false,
                       params: {
                          _token: "{{csrf_token()}}"
                        },

                   });

                     myDropzone.on("success", function(file,resp){
                       if(resp=="success"){
                         alert("Image uploaded successfully");
                       }
                       else {
                         alert("Faild to upload image! Try again");
                       }
                     });


                    jQuery("button#uploadPhoto").click(function(){
                      myDropzone.processQueue();
                    });
                });
             </script>

profile image model:

class profile_image extends Model
{
    protected $table="profile_images";

    public function user()
    {
      return $this->belongsTo('App\User');
    }

also added the inverse in the User model.

Thanks.
