在视图中显示数据时遇到问题。我需要在视图中显示teacher's remark。
我把它放在我的控制器<pre>';print_r($data);die中，$data ['exam_result']输出老师的评语。
控制器：

public function view($id)
    {
        $data['exam_result'] = $this->examgroupstudent_model->searchStudentExams($student['student_session_id'], true, true);

        $this->load->view('layout/header', $data);
        $this->load->view('student/studentShow', $data);
        $this->load->view('layout/footer', $data);
    }

产品型号：

public function searchStudentExams($student_session_id, $is_active = false, $is_publish = false) {
        $inner_sql = "";
        if ($is_active) {
            $inner_sql = "and exam_group_class_batch_exams.is_active=1 ";
        }
        if ($is_publish) {
            $inner_sql .= "and exam_group_class_batch_exams.is_publish=1 ";
        }
        $sql = "SELECT exam_group_class_batch_exam_students.*,exam_group_class_batch_exams.exam_group_id,exam_group_class_batch_exams.exam,exam_group_class_batch_exams.date_from,exam_group_class_batch_exams.date_to,exam_group_class_batch_exams.description,exam_groups.name,exam_groups.exam_type FROM `exam_group_class_batch_exam_students` INNER JOIN exam_group_class_batch_exams on exam_group_class_batch_exams.id=exam_group_class_batch_exam_students.exam_group_class_batch_exam_id  INNER JOIN exam_groups on exam_groups.id=exam_group_class_batch_exams.exam_group_id WHERE student_session_id=" . $this->db->escape($student_session_id) . $inner_sql . " ORDER BY id asc";

        $query = $this->db->query($sql);
        $student_exam = $query->result();

        if (!empty($student_exam)) {
            foreach ($student_exam as $student_exam_key => $student_exam_value) {
                $student_exam_value->exam_result = $this->examresult_model->getStudentExamResults($student_exam_value->exam_group_class_batch_exam_id, $student_exam_value->exam_group_id, $student_exam_value->id, $student_exam_value->student_id);
            }
        }
        return $student_exam;
    }

查看方式：

Teacher's Remark: <?php echo $student->teacher_remark; ?>;
