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

$route['default_controller'] = 'welcome';

$route['404_override'] = '';

Step 3: Create Controller

In this step, we have to create “AjaxImageUpload” controller with index() and uploadImage(). so create AjaxImageUpload.php file in this path application/controllers/AjaxImageUpload.php and put bellow code in this file:



class AjaxImageUpload extends CI_Controller {


* Manage __construct


* @return Response


public function __construct() {


$this->load->helper(array('form', 'url'));



* Manage index


* @return Response


public function index() {

$this->load->view('ajaxImageUploadForm', array('error' => '' ));



* Manage uploadImage


* @return Response


public function uploadImage() {

header('Content-Type: application/json');

$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());

echo json_encode($error);

}else {

$data = $this->upload->data();

$success = ['success'=>$data['file_name']];

echo json_encode($success);





Step 4: Create View

In this step we will create ajaxImageUploadForm.php view file . In this file we will write design of html form using form helper and url helper. We also write jquery ajax code on this file. So let’s update following file:




<title>Image Upload Example from Scratch</title>

<script src=""></script>

<script src=""></script>



<?php echo form_open_multipart('ajax-image-upload/post');?>

<input type="file" name="image" size="20" />

<input type="submit" value="upload" />


<div style="display: none;">

<img src="">



<script type="text/javascript">




var options = {

complete: function(response)



alert('Image Upload Successfully.');




alert('Image Upload Error.');
