Upload image , create multiple thumbnail using codeigniter

In this i have share module for upload image with creating multiple thumbnail in codeigniter.

1) Create MySQL database and table :

<?php
CREATE TABLE `picture` (
  `id` int(11) NOT NULL,
  `url` int(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
ALTER TABLE `picture` ADD PRIMARY KEY (`id`);.
ALTER TABLE `picture`  MODIFY `id` int(11) NOT NULL AUTO_INCREMENT;
?>

2)Craete a model file in application/models

if (!defined('BASEPATH'))

    exit('No direct script access allowed'); 

class Upload_model extends CI_Model { 

    private $_ID;

    private $_url; 

    public function setID($ID) {

        $this->_ID = $ID;

    } 

    public function setURL($url) {

        $this->_url = $url;

    }

    public function getPicture() {        

        $this->db->select(array('p.id', 'p.url'));

        $this->db->from('picture p');  

        $this->db->where('p.id', $this->_ID);    

        $query = $this->db->get();

       return $query->row_array();

    }   

    public function create() {

        $data = array(

            'url' => $this->_url,

        );

        $this->db->insert('picture', $data);

        return $this->db->insert_id();

    }

}

?>

3) Upload constant file in config

<?php $root = "http://" . $_SERVER['HTTP_HOST']; $root .= str_replace(basename($_SERVER['SCRIPT_NAME']), "", $_SERVER['SCRIPT_NAME']); $constant['base_url'] = $root; define('HTTP_UPLOAD_LARGE_PATH', $constant['base_url'] . 'assets/uploads/_large/'); define('HTTP_UPLOAD_MEDIUM_PATH', $constant['base_url'] . 'assets/uploads/_medium/'); define('HTTP_UPLOAD_THUMB_PATH', $constant['base_url'] . 'assets/uploads/_thumb/'); define('HTTP_UPLOAD_MOBILE_PATH', $constant['base_url'] . 'assets/uploads/_mobile/'); define('ROOT_UPLOAD_PATH', BASH_PATH . 'assets/uploads/'); ?>

4) Craete controller

if (!defined('BASEPATH'))

    exit('No direct script access allowed'); 

class Upload extends CI_Controller { 

    public function __construct() {

        parent::__construct();

        $this->load->model('Upload_model', 'upl');

    }

    public function index() {

        $data['page'] = 'upload-img';

        $data['title'] = 'Upoad Image | TechArise';        

        $this->load->view('upload/index', $data);

    }

    public function save() {      

        if ($this->input->post('upload_img')) {

            $path = ROOT_UPLOAD_PATH;            

            $initi = $this->upload->initialize(array(

                "upload_path" => $path,

                "allowed_types" => "gif|jpg|jpeg|png|bmp",

                "remove_spaces" => TRUE

            ));

            $imagename = 'no-img.jpg';

            if (!$this->upload->do_upload('imageURL')) {

                $error = array('error' => $this->upload->display_errors());

                echo $this->upload->display_errors();

            } else {

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

                $imagename = $data['file_name'];

            } 

            $image_sizes = array('_mobile'=>array(75,75), '_thumb' => array(300, 200),'_medium' => array(500, 270), '_large' => array(750, 406));

            $this->load->library('image_lib');

            foreach ($image_sizes as $key=>$resize) {

                $config = array(

                    'source_image' => $data['full_path'],

                    'new_image' => ROOT_UPLOAD_PATH .'/'.$key,

                    'maintain_ratio' => FALSE,

                    'width' => $resize[0],

                    'height' => $resize[1],

                    'quality' =>70,

                );

                $this->image_lib->initialize($config);

                $this->image_lib->resize();

                $this->image_lib->clear();

            }            

            $this->load->library('image_lib', $config);

            $this->image_lib->resize();

            $this->upl->setURL($imagename);            

            $this->upl->create();                          

            $this->session->set_flashdata('img_uploaded_msg', '<div class="alert alert-success">Image uploaded successfully!</div>');

            $this->session->set_flashdata('img_uploaded', $imagename);

            redirect('/');

        }

    }

}

?>

5) Create view :

<?php $this->load->view('templates/header'); ?> <div class="row"> <div class="col-lg-12"> <h2>Upload Image and Create Multiple Thumbnail Sizes using CodeIgniter with MySQL</h2> </div> </div><!-- /.row --> <div class="row"> <div class="col-lg-12"> <?php echo $this->session->flashdata('img_uploaded_msg'); ?> </div> </div><!-- /.row --> <?php if(empty($this->session->flashdata('img_uploaded'))) { ?> <div class="row"> <form action="<?php echo site_url();?>upload/save" class="img-upl-validation" id="img-upl-validation" enctype="multipart/form-data" method="post" accept-charset="utf-8"> <div class="col-lg-6"> </div> <div class="col-lg-6"> <div class="form-group"> <label for="image">Upload Image</label> <input type="file" name="imageURL" id="url" class="filestyle" value="" data-icon="false" data-buttontext="Choose image"> </div> </div> <div class="col-lg-12 col-sm-12"> <div class="form-group text-right padT"> <button type="submit" name="upload_img" id="upload-img" value="upl-img" class="btn btn-primary mrgT">Upload</button> </div> </div> </form> </div><!-- /.row --> <?php } else { ?> <div class="container"> <h2>Images</h2> <img width="700" height="400" class="img-thumbnail" src="<?php print HTTP_UPLOAD_LARGE_PATH.$this->session->flashdata('img_uploaded');?>"><br> <img width="500" height="270" class="img-thumbnail" src="<?php print HTTP_UPLOAD_MEDIUM_PATH.$this->session->flashdata('img_uploaded');?>"><br> <img width="300" height="200" class="img-thumbnail" src="<?php print HTTP_UPLOAD_THUMB_PATH.$this->session->flashdata('img_uploaded');?>"><br> <img width="75" height="75" class="img-thumbnail" src="<?php print HTTP_UPLOAD_MOBILE_PATH.$this->session->flashdata('img_uploaded');?>"><br> </div> <?php } ?> <?php $this->load->view('templates/footer'); ?>
