Adding Records View:

@extends('layouts.app')
@section('content')

<script type="text/javascript">
    $(function () {
        $('.add').click(function () {
            var n = ($('.resultbody tr').length - 0) + 1;
            var tr = '<tr><td class="no">' + n + '</td>' +
                    '<td><input type="text" class="name form-control" name="name[]" value="{{ old('name') }}"></td>'+
                    '<td><input type="text" class="fname form-control" name="fname[]" value="{{ old('fname') }}"></td>'+
                    '<td><input type="text" class="rollno form-control" name="rollno[]" value="{{ old('rollno') }}"></td>'+

Student Controller:

public function store(Request $request)
    {
        $input = Input::all();
        $condition = $input['id'];
        for($id = 0; $id<$condition; $id++){
            $student = new Student;
            $student->name = $input['name'][$id];
            $student->save();
        }
        return view('students.index');
    }

Answer 1

You're getting that error because you have no id form field. Try this:

public function store(Request $request)
{
    $input = Input::all();
    $condition = $input['name'];
    foreach ($condition as $key => $condition) {
        $student = new Student;
        $student->name = $input['name'][$key];
        $student->fname = $input['fname'][$key];
        $student->rollno = $input['rollno'][$key];
        $student->obtainedmarks = $input['obtainedmarks'][$key];
        $student->totalmarks = $input['totalmarks'][$key];
        $student->percentage = $input['percentage'][$key];
        $student->save();
    }
    return view('students.index');
}
