Question

以下是我的代码的一部分。但是当我运行该代码时，我收到错误＆＃34;试图获得非对象的属性＆＃34;。

            $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);
                    }
                }                
            }

我将如何解决这个问题？

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

Answer 1

问题在这里：

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

要修复它，请对学生数组使用$studentS变量，对循环迭代器使用$student，如下所示：

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