{

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

    public function save()
    {
       request()->validate([
         'file'  => 'required|mimes:doc,docx,pdf,txt|max:2048',
       ]);

       if ($files = $request->file('fileUpload')) {
           $destinationPath = 'public/file/'; // upload path
           $profilefile = date('YmdHis') . "." . $files->getClientOriginalExtension();
           $files->move($destinationPath, $profilefile);
           $insert['title'] = "$profilefile";
        }
        
        $check = Document::insertGetId($insert);
