How to append user id with checkbox value?

in the foreach you can name them dynamically i.e. name of every checkbox include student-id you should call that foreach in the controller as well

@foreach($student as $stud){
<input type="hidden" name="{{$stud->id}}" value="0">
<input type="checkbox" name="$stud->id" value="1">present
@endforeach 

@ershakti thank you, I see some hope in your answer, can you please give a code example of how can I get student id and 'absent', 'present' status in the controller and inserting it in Attendance model.

Thank you very much

foreach($student as $stud)
{
    $studid=$stud->id;
     $evento = $request->student()->attend()->create([
      'stdid' => $studid,
      'status'=>($request->$studid ==1)?'p':'a',
      'data'=>time()
      ]);
}

Please checko this might help

I would do something like this:

In your view:

@foreach ($students as $student)

    <ul class="list-group">
        <li class="list-group-item"><input type="checkbox" checked value="1" name="stud_id[]">Present</li>
<li class="list-group-item"><input type="checkbox" value="2" name="stud_id[]">Absent</li>
    </ul>

//Put Hidden Input here with the $student->id
@endforeach

In your controller:

    $count = count($request->student_id);
    for($i = 0; $i < $count; ++$i){
        if($request->student_id[$i] == null){
        //If this student doen't have 1 or 2 checked, do nothing. Not really for your case scenario but I don't see why not leave this as a safeguard. 
        } else {
            //CREATE this student attendance row.
        }       
    }
