how to use cookie in laravel 5.4 to store data

i am creating a website which needs to store user info and save to cookie. here is my get cookie controller

public function index($id, Request $request)
{    
    $petitions = Petitions::where('id',$id)->first();
    $sign->name  = $request->cookie('name'); 
    $sign->email = $request->cookie('email');

    return view('petitions.index', compact('petitions'))->with(['name'=>$sign->name,'email'=>$sign->email]);
}

and here is set cookie controller

public function store(Request $request)
{
    $sign = new ActionUsers();

    $sign->name = $request->get('name');
    $sign->email = $request->get('email');
    $sign->job = $request->get('job');
    $sign->reason = $request->get('reason');
    $sign->ip_address = $request->get('ip_address');
    $sign->petition_id = $request->get('petition_id');
    $sign->is_anonymous = $request->get('is_anonymous');

    $sign->save(); 

    $name_cookie = cookie('name', $sign->name, 30);
    $email_cookie = cookie('email', $sign->email, 30);

    return back()->withCookie($name_cookie,$email_cookie);
}

my view to check cookie existed

@if( isset($sign->name)  &&  isset($sign->email) )
    done!
@else Oops! Error

and return error Creating default object from empty value in $sign->name = $request->cookie('name'); $sign->email = $request->cookie('email');
