error while updating my records

Question

This is my controller :

        public function updatedata($id)
                {
                  //$id=$this->input->get('id');
                  $result['data']=$this->Form_model->displayrecordsById($id);

                      $this->form_validation->set_rules('fname', 'First name', 'required');
                      $this->form_validation->set_rules('lname', 'Last name', 'required');
                      $this->form_validation->set_rules('username', 'Username', 'required|min_length[5]|max_length[12]');
                      $this->form_validation->set_rules('email', 'Email', 'required|valid_email');

                      if ($this->form_validation->run() == FALSE)
                      {
                          $this->load->view('update_records',$result);
                      } 

                      else 
                      {
                          $config['upload_path']   = './uploads/';
                          $config['allowed_types'] = 'gif|jpg|png';
                          $this->load->library('upload', $config);

                              $fn=$this->input->post('fname');
                              $ln=$this->input->post('lname');
                              $un=$this->input->post('username');
                              $em=$this->input->post('email');
                              if($this->upload->do_upload('filename'))
                                   {
                                       $fi= $this->upload->data('file_name');
        //                               $file = ("uploads/".$result['data']->filename);
        //                                //delete the existing file if needed
        //                                if (file_exists($file)) {
        //                                    unlink($file);
        //                                }
                                   }
                              else
                                   {
                                      $fi= $result['data']->filename;
                                   }
                              $this->Form_model->updaterecords($fn,$ln,$un,$em,$fi,$id);
                              echo 'Successfully updated your record';
                              //exit();
                          }

Hope this will help you :

First: Replace it

$fi= $result['data']->filename;

With this

 $fi= $result['data'][0]->filename;

Second : To Replace the existing image you should add $config['overwrite']=TRUE; in your config like this :

$config['upload_path']   = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['overwrite'] = TRUE;
$this->load->library('upload', $config);
/*........your other code .........*/
