如何解决laravel中的错误``试图获取非对象的属性''

Question

The following is the part of my code. But when I run that code, I am getting error "Trying to get property of non-object".

            $searchdate = Input::get('curdate');
            $teacherid = Auth::user()->id;
            $student = WysStudent::where('studcls',$id)->get();
            $clss = WysClass::where('clsteacher_id',$teacherid)->get();
            $attendence_tbl = WysAttendancename::where('cls_id',$id)->first();
            $wys_attendence_table = $attendence_tbl->attendance_name;
            $attendance = DB::table($wys_attendence_table)->where('adate','=',$searchdate)->get();
            if($attendance && $student){
                foreach ($attendance as $attendance) {
                    foreach ($student as $student) {
                        var_dump($student->id);
                    }
                }                
            }

How will I solve this problem??

$attendance = DB::table($wys_attendence_table)->where('adate','=',$searchdate)->get();

Answer 1

Issue is here:

$student = WysStudent::where('studcls',$id)->get();
…
foreach ($student as $student) {

To fix it use $studentS variable for array of students and $student for loop iterator, like this:

$students = WysStudent::where('studcls',$id)->get();
…
foreach ($students as $student) {
