Laravel 5.1 Ajax file upload

I am trying to upload multiple files with AJAX using jFiler package. I have a form where users upload files and have a preview for images and videos that are uploaded. And then when the user later fills up the rest of the form, and submits it, I want to save the paths of the files in the database, with the id of the article they belong to. I am therefore saving file path to session in my controller and saving it to DB like this:

//save article to DB
public function store(Create $request) {
  $slug = str_slug($request['name']);
  $count = Article::where('slug', 'like', '%'.$slug.'%')->count();

  if($count)
    $slug = $slug .'-'. $count;

  $article = Article::create(array_merge($this->fillobject($request), $data));

  //store external media for the article
  $externalMedia = ExternalMedia::create([
    'url' => $request->input('external_media'),
    'article_id' => $article->id
    ]);


  //if files are uploaded store call fileUpload and store files
  $this->fileUpload(Session::get('filePath'), $article->id);

  return Redirect::route('admin.articles.show',['id'=>$article->id]);
}

public function fileUpload($files, $id) {

  $articleMedia = [];
  $articleMediaFiles = Media::where('article_id', $id)->get(['path']);

  foreach($articleMediaFiles as $articleMediaFile) {
    $articleMedia[] = $articleMediaFile->path;
  }

  foreach($files as $file) {
    $oldPath = explode('articles/', $file);
    $directoryPath = $oldPath[0].'articles/'.$id;
    $newPath =  explode('public/',   $oldPath[0].'articles/'.$id.'/'.$oldPath[1]);

    if(!File::exists($directoryPath))
      File::makeDirectory($directoryPath, 0755, true);



    if(!in_array($newPath[1], $articleMedia))
      Media::create(['path' => $newPath[1], 'article_id' => $id]);

    Image::make($file)->resize(100, 100)->save($newPath[1]);
  }
}

public function ajaxUpload() {
  $name = "";
  $path = public_path('files/uploads/articles/');

  if (Input::hasFile('file')) {
    $files = Input::file('file');

    foreach($files as $file){
      $filePath[] = $path.$file->getClientOriginalName();
      Image::make($file)->resize(100, 100)->save($path.'/'.$file->getClientOriginalName());
    }
        Session::put('filePath', $filePath);
        return json_encode($filePath);
  }
}

My issue with this code is that I only save one file path to DB when uploading multiple files.
