defined('BASEPATH') OR exit('No direct script access allowed');


$route['default_controller'] = 'welcome';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;


$route['image-upload'] = 'ProfilePicUpload';
$route['image-upload/post']['post'] = "ProfilePicUpload/storeProfileDP";

Step 3: Create ProfilePicUpload Controller

application/controllers/ProfilePicUpload.php

<?php


class ProfilePicUpload extends CI_Controller {


   /**
    * Manage __construct
    *
    * @return Response
   */
   public function __construct() { 
      parent::__construct(); 
      $this->load->helper(array('form', 'url')); 
   }


   /**
    * Manage index
    *
    * @return Response
   */
   public function index() { 
      $this->load->view('profileDpFormLoadData', array('error' => '' )); 
   } 


   /**
    * Manage storeProfileDP
    *
    * @return Response
   */
   public function storeProfileDP() { 


      $config['upload_path']   = './uploads/'; 
      $config['allowed_types'] = 'gif|jpg|png'; 
      $config['max_size']      = 1024;
      $this->load->library('upload', $config);


      if ( ! $this->upload->do_upload('image')) {
         $error = array('error' => $this->upload->display_errors()); 
         $this->load->view('profileDpFormLoadData', $error); 
      }else { 


        $uploadedImage = $this->upload->data();
        $this->resizeImage($uploadedImage['file_name']);


        print_r('Image Uploaded Successfully.');
        exit;
      } 
   }


   /**
    * Manage storeProfileDP
    *
    * @return Response
   */
   public function resizeImage($filename)
   {
      $source_path = $_SERVER['DOCUMENT_ROOT'] . '/uploads/' . $filename;
      $target_path = $_SERVER['DOCUMENT_ROOT'] . '/uploads/thumbnail/';
      $config_manip = array(
          'image_library' => 'gd2',
          'source_image' => $source_path,
          'new_image' => $target_path,
          'maintain_ratio' => TRUE,
          'create_thumb' => TRUE,
          'thumb_marker' => '_thumb',
          'width' => 150,
          'height' => 150
      );


      $this->load->library('image_lib', $config_manip);
      if (!$this->image_lib->resize()) {
          echo $this->image_lib->display_errors();
      }


      $this->image_lib->clear();
   }
} 
?>

Step 4: Create View File

application/views/profileDpFormLoadData.php

<!DOCTYPE html>
<html> 
<head> 
  <title>Codeignier 3 Image Upload with Resize Example from Scratch - www.pakainfo.com</title> 
</head>


<body> 


  <?php echo $error;?> 
  <?php echo form_open_multipart('image-upload/post');?> 
     <input type="file" name="image" size="20" />
     <input type="submit" value="upload" /> 
  </form> 


</body>
</html>

Now i requred to make 2 main folder. First you have to make “uploads” and inside uploads folder you have to make second new folder “thumbnail”.
