Crop and Save Image using jQuery Croppie in Codeigniter 4

  • Install Codeigniter 4 Application
  • Basic App Configurations
  • Create Database and Table
  • Setup Database Credentials
  • Create Controller
  • Create Views
  • Setup Routes
  • Start Development server

Step 1 – Install Codeigniter 4 Application

First of all, you need to ownload the latest version of Codeigniter 4. So, visit this link https://codeigniter.com/download Download Codeigniter 4 app and unzip the setup in your local system xampp/htdocs/ .

Note that, please change the download folder name “demo”.

Step 2 – Basic App Configurations

Now, you need to some basic configuration on the app/config/app.php file, so let’s go to application/config/config.php and open this file on text editor.

Set Base URL like this

public $baseURL = 'http://localhost:8080';
To
public $baseURL = 'http://localhost/demo/';

Step 3 – Create Database and Table

Create a database and table by executing the following SQL query:

CREATE DATABASE demo;

CREATE TABLE images (
    id int(11) NOT NULL AUTO_INCREMENT COMMENT 'Primary Key',
    name varchar(100) NOT NULL COMMENT 'Name',
    type varchar(255) NOT NULL COMMENT 'file type',
    created_at varchar(20) NOT NULL COMMENT 'Created date',
    PRIMARY KEY (id)
  ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='demo table' AUTO_INCREMENT=1;

Step 4 – Setup Database Credentials

To connect your codeigniter 4 app to the database. So, visit app/Config/ directory and open Database.php. Then add the databasae details like below into database.php file:

public $default = [
        'DSN'      => '',
        'hostname' => 'localhost',
        'username' => 'test',
        'password' => '4Mu99BhzK8dr4vF1',
        'database' => 'demo',
        'DBDriver' => 'MySQLi',
        'DBPrefix' => '',
        'pConnect' => false,
        'DBDebug'  => (ENVIRONMENT !== 'development'),
        'cacheOn'  => false,
        'cacheDir' => '',
        'charset'  => 'utf8',
        'DBCollat' => 'utf8_general_ci',
        'swapPre'  => '',
        'encrypt'  => false,
        'compress' => false,
        'strictOn' => false,
        'failover' => [],
        'port'     => 3306,
	];

Step 5 – Create Controller

Create CropImageController.php file. So, visit app/Controllers directory and create CropImageController.php.Then add the following code into it:

<?php namespace App\Controllers;

use CodeIgniter\Controller;

class CropImageUpload extends Controller
{
    public function index()
    {    
         return view('crop_image_form');
    }

    public function store()
    {  
	       helper(['form', 'url']);
        
	       $db    = \Config\Database::connect();
         $builder = $db->table('images');


         $data = $_POST["image"];

         $image_array_1 = explode(";", $data);

         $image_array_2 = explode(",", $image_array_1[1]);

         $data = base64_decode($image_array_2[1]);

         $imageName = time() . '.png';

         file_put_contents($imageName, $data);

         $image_file = addslashes(file_get_contents($imageName));

         $save = $builder->insert(['title' =>  $image_file]);

         $response = [
          'success' => true,
          'data' => $save,
          'msg' => "Crop Image has been uploaded successfully in codeigniter"
         ];
    

       return $this->response->setJSON($response);

    }
}

The index() function renders the contact form template into the view.

The save() method handles the form of validation and contains various variables. And store image into db and directory.

Step 6 – Create Views

Create crop_image_form.php view file, so visit application/views/ directory and create crop_image_form.php file. Then add the following HTML into crop_image_form.php file:

<html>  
    <head>  
        <title>Codeigniter 4 Crop Image Before Uplaod using jQuery Croppie - Laratutorials.com</title>  
  
  <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">

        <h4 class="modal-title">Crop & Resize Upload Image in PHP with Ajax</h4>

      <div class="modal-body">

            <div id="image_demo" style="width:350px; margin-top:30px"></div>
          </div>
          <div class="col-md-4" style="padding-top:30px;">
        <br />
        <br />
        <br/>
            <button class="btn btn-success crop_image">Save</button>
          </div>
        </div>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

<script>  
$(document).ready(function(){

 $image_crop = $('#image_demo').croppie({
    enableExif: true,
    viewport: {
      width:200,
      height:200,
      type:'square' //circle
    },
    boundary:{
      width:300,
      height:300
    }    
  });

  $('#before_crop_image').on('change', function(){
    var reader = new FileReader();
    reader.onload = function (event) {
      $image_crop.croppie('bind', {
        url: event.target.result
      }).then(function(){
        console.log('jQuery bind complete');
      });
    }
    reader.readAsDataURL(this.files[0]);

    $('#imageModel').modal('show');
  });

  $('.crop_image').click(function(event){
    $image_crop.croppie('result', {
      type: 'canvas',
      size: 'viewport'
    }).then(function(response){
      $.ajax({
        url:"<?php echo base_url(); ?>public/index.php/CropImageUpload/store",  
        type:'POST',
        data:{"image":response},
        success:function(data){
          $('#imageModel').modal('hide');
          alert('Crop image has been uploaded');
        }
      })
    });
  });

});  
</script>

Step 7 – Setup Routes

To define a route, So, visit app/Config/ directory and open Routes.php file. Then add the following routes into it:

$routes->setDefaultController('CropImageController');
$routes->get('/', 'CropImageController::index');
$routes->post('save', 'CropImageController::store');

Note that, the routes will be displaying the image upload form and bootstrap modal for cropping image and submitting the data in the database on successful form submission.

Step 8 – Start Development server

Execute the following command into command prompt or terminal to start the codeigniter 4 application:

php spark serve

Then visit your web browser and hit the following url on it:

http://localhost/demo/

OR

http://localhost:8080/
