下载pdf时遇到404错误页面

问题描述

我认为这是一个权限问题，因为从管理页面下载 PDF 工作得很好。但是当我为用户复制代码时，我得到了一个 404 错误页面。

用户控制器 (Savepdf.PHP)

    public function presult($id,$term)
    {
       if (!$this->rbac->hasPrivilege('student','can_view')) {
            access_denied();
        }

        $data['title']         = 'Student Details';
        $student               = $this->student_model->get($id);
        $data['student']        = $student;
        $gradeList             = $this->grade_model->get();
        $class_id              = $student["class_id"];
        $studentSession        = $this->student_model->getStudentSession($id);
        $student_session_id     = $studentSession["student_session_id"];
        $student_session         = $studentSession["session"];
        $data['sch_setting']     = $this->sch_setting_detail;
        $current_student_session = $this->student_model->get_studentsession($student['student_session_id']);
        $data["session"]              = $current_student_session["session"];
        $data['principalmt_comment'] = $this->Mtcomment_model->GetPrincipalmtComment($id,$student_session_id);
        $data['teacher_comment'] = $this->Comment_model->GetTeacherComment($id,$student_session_id);
        $data['principal_comment'] = $this->Comment_model->GetPrincipalComment($id,$student_session_id);
        $student_class_section = $this->student_model->currentClassSectionById($id,$student_session_id);
       
        if($term == "first")
        {
            $data['subjectftscores'] = $this->getFirstTermResult($id,$class_id);

            $view = $this->load->view('user/savepdf/first_term',$data,TRUE);
            $title = $student['firstname'] . " " . $student['lastname']."First Term Result";
            $filename = $student['firstname'] . "_" . $student['lastname']."_firstterm.pdf";
            $this->show_pdf($view,$title,$filename);            
        }
    }
