should pass parameters in do_upload function?

in part try put

$img = "img" // input name="img" $this->upload->do_upload($img) 

if not try / test form action="http://localhost:8080/ci/admin/plot/do_upload"

you may need set routes in route.php

code

<?php defined('basepath') or exit('no direct script access allowed');  class plot extends ci_controller {  public function __construct() {     parent::__construct();     $this->load->library('admin_layout');     $this->load->model('admin/plot_model');     $this->config->load('plot_rules');     $this->output->enable_profiler(true); }  public function index() {    $this->load->view('upload_form', array('error' => ' ' )); }  public function do_upload() {         $config['upload_path'] = './images/';         $config['allowed_types'] = 'gif|jpg|png';         $config['max_size']  = 100;         $config['max_width']  = 1024;         $config['max_height'] = 768;          $this->load->library('upload', $config);          $img = "img";          if ( ! $this->upload->do_upload($img))         {                 $error = array('error' => $this->upload->display_errors());                 $this->load->view('upload_form', $error);                  print_r($error);         }         else         {                 $data = array('upload_data' => $this->upload->data());                  $field_data = $this->upload->data();                  echo $field_data['file_name']; // etc                   $this->load->view('upload_success', $data);                 print_r($data);         } } }
