Как создать Controller для multiple insert data?

$model = new Schedule();
        $count=0;
        if (isset($_POST['Group_id']) && $_POST['Group_id']!=null)
        $model->Group_id = $_POST['Group_id'];
        for ($i=1; $i<=6; $i++){
            $model->Day_id = $i;
            for ($j=1; $j<=4; $j++){
                if (isset($_POST[$i.'_subject_'.$j]) && $_POST[$i.'_subject_'.$j]!=null) {
                   $model->pair = $_POST[$i.'_pair_'.$j];
                   $model->Subject_id = $_POST[$i.'_subject_'.$j];
                   $model->type = $_POST[$i.'_type_'.$j];
                   $model->Teacher_id = $_POST[$i.'_teacher_'.$j];
                   $model->isEven = $_POST[$i.'_even_'.$j];
              
                    $model->save();
                    $count++;
                }
            }
        }
            print_r($model);
