['id'=>'required|integer']

You can write a custom validation rule or you can do

if(!in_array("name", $request->all())){
    return redirect()->back()->with('errorMessage','the name param is not allowed.')->withInput();
}

and to show an error message in blade file

@if (session('errorMessage'))
    {{ session('errorMessage') }}
@endif
