How to store input data with user id in Laravel using eloquent?

Question

I have four field in database : Profile_id (primary Key), user_id, First_name, Last_name

 public function store(Request $request)
 {
    $this->validate($request, [
        'first_name' => 'required|max:50',
        'last_name' => 'required|max:50',
    ]);
    $user_id= Auth::user()->id;
    $postdata = $request->all();
    profile::create($postdata);
    return redirect('profile');
}

This is storing only First_name and last_name, How to save user id with others.

Answer 1

public function store(Request $request)
{
$this->validate($request, [
    'first_name' => 'required|max:50',
    'last_name' => 'required|max:50',
]);
$data['user_id'] = Auth::user()->id;
$data['first_name'] = $request['first_name'];
$data['last_name'] = $request['last_name'];
profile::create($data);
return redirect('profile');
}

Try this way it will store your data
