使用codeigniter将数据保存在数据库中

Question

我想将图像与我的其他数据（如idnumber，name等）结合起来。我仍然对如何操作感到困惑，但我可以将其保存到文件夹和数据库但我无法显示< / p>

class Addstudent extends CI_Controller { 
     function indexes(){

          if($this->session->userdata('logged_in'))
        {
            $session_data = $this->session->userdata('logged_in');

            $data['Username'] = $session_data['Username'];
            $this->load->view('addstudentinformation',$data);
        } else{
            redirect('welcome', 'refresh');
        }
           if((!isset($session_data) || $session_data !=TRUE)) {

            redirect('welcome', 'refresh');
        }
    }
     function do_upload(){
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png|jpeg';

    $this->upload->initialize($config);

        if ($this->form_validation->run() == FALSE){



            $this->indexes();
        }
        else{
       $images =   file_get_contents($_FILES['FileToUpload']['tmp_name']);  
            $images = "FileToUpload";
           $this->upload->do_upload($images);

        array('upload_data' =>  $this->upload->data());


           $data= array(
                        'Firstname' => $this->input->post('Firstname'),
                        'Middlename' => $this->input->post('Middlename'),
                        'Lastname' => $this->input->post('Lastname'),

                                                'Yearlevel' => $this->input->post('Yearlevel'),

                                        'Imageupload'=> $images,

                        'Province' => $this->input->post('Province'),
                                                'Town' => $this->input->post('Town'),
                        'Barrio' => $this->input->post('Barrio'),
                        'Permanentaddress' => $this->input->post('Permanentaddress'),
                                                'Contactperson' => $this->input->post('Contactemergency'),
                        'Contactpersonnumber' => $this->input->post('Contactnumber'),


                    ); 
            $this->db->insert('studentinformation',$data);
           redirect('educationalbackground/index', refesh); 

        }


    }

这就是用数据库查看的方式
