Step 2: Create Routes

application/config/routes.php

<?php
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”.

I hope you get an idea about Codeignier 3 Image Upload with Resize.
