How to upload image file on codeigniter 3?

I've tried everything to code upload the image file but I still stuck and it keeps an error. It can't detect the data of the image file so it can't store to the database when I submitted the form. I saw every tutorial I've been searched and look into my code seems everything right but why it still keeps an error.

Controller

public function create()  {      if (!$this->session->userdata('user_logged')) {          redirect('Auth');      }        $data["title"] = "Form Create Blog";      $data["landingpage"] = false;      $data['content'] = 'component/admin/blog/blog_create';        $this->form_validation->set_rules('blogTitle', 'Title tidak boleh kosong', 'required|max_length[50]');      $this->form_validation->set_rules('blogHeaderImg', 'Header Image tidak boleh kosong', 'required');      $this->form_validation->set_rules('blogKeyword', 'Keyword tidak boleh kosong', 'required|max_length[50]');      $this->form_validation->set_rules('blogContent', 'Content tidak boleh kosong', 'required');          if ($this->form_validation->run() == FALSE) {          $this->load->view('index', $data);      } else {          $config['upload_path'] = realpath(APPPATH . '../assets/img/upload/blog/header_image');          $config['allowed_types'] = 'jpg|png|PNG';          $nmfile = time() . "_" . $_FILES['blogHeaderImg']['name'];          $config['file_name'] = $nmfile;            $this->load->library('upload', $config);              if (!$this->upload->do_upload("blogHeaderImg")) {                  $error = array('error' => $this->upload->display_errors());                echo '<div class="alert alert-danger">' . $error['error'] . '</div>';          } else {              $data = array('upload_data' => $this->upload->data());                $header_image = $data['upload_data']['file_name'];                $this->M_Blog->storeBlogData($header_image);                print_r($_FILES['blogHeaderImg']);                $this->session->set_flashdata('flashAddBlog', 'Data berhasil <strong>ditambahkan</strong>');              redirect('blog');          }      }  }  

Model

public function storeBlogData($header_image)  {      $data = [          'title' => $this->input->post('blogTitle', TRUE),          'header_image' => $header_image,          'content' => $this->input->post('blogContent', TRUE),          'blog_keyword' => $this->input->post('blogKeyword', TRUE),          'created_by' => $this->session->userdata('user_logged')->id,          'last_modified_by' => $this->session->userdata('user_logged')->id,          'is_deleted' => 'n'      ];        $this->db->insert('blog', $data);  }
