We will use how to use image crop with jquery croppie using in codeigniter. Let's get started with how to image crop with jquery croppie use in codeigniter.

Here i will give you many example how you can use image crop with jquery croppie in codeigniter.

Step 1 : Create Codeigniter Project

we require to set up codeigniter project, so first fire bellow command:

composer create-project codeigniter4/appstarter
Step 2 : Create Database Connection

To make the database connection open the app/Config/Database.php file, further add the database name, username and password simultaneously:

public $default = [
    'DSN'      => '',
    'hostname' => 'localhost',
    'username' => 'root',
    'password' => '',
    'database' => 'db_name',
    '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,
];

If you are working on local development server either MAMP or XAMPP so don’t forget to define the following value for the hostname property in app/Config/Database.php:

# MAMPP
public $default = [
    'hostname' => '/Applications/MAMP/tmp/mysql/mysql.sock',
]

# XAMPP
public $default = [
    'hostname' => '/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock',
]
Step 3 : Create Table in Database

You need to create a table in the database with some columns for storing the image files in the database. Head over to the PHPMyAdmin and execute the following SQL query in the SQL section:

CREATE TABLE upload_images (
    id int(11) NOT NULL AUTO_INCREMENT COMMENT 'Primary Key',
    name varchar(150) NOT NULL COMMENT 'Name',
    created_at varchar(20) NOT NULL COMMENT 'Created date',
    PRIMARY KEY (id)
  ) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='database table' AUTO_INCREMENT=1;
Step 4 : Create New Controller

A controller is the file that holds the logic for storing and showing the image crop, image storage component in Codeigniter. Head over to the app/Controllers path and create an ImageCrop.php file.

Finally, add the following code in app/Controllers/ImageCrop.php:

<?php 
namespace App\Controllers; 
use CodeIgniter\Controller;
 
class ImageCrop extends Controller
{
    public function index()
    {
        return view('home');
    }
 
    public function store()
    {  
        helper(['form', 'url']);=        
        $database    = \Config\Database::connect();
        $db = $database->table('upload_images');
        $data = $_POST["image"];
 
        $img_arr_a = explode(";", $data);
        $img_arr_b = explode(",", $img_arr_a[1]);
        $data = base64_decode($img_arr_b[1]);
        $img_name = time();
 
        file_put_contents($img_name, $data);
        $img_file = addslashes(file_get_contents($img_name));
        $store = $db->insert(['name' =>  $img_file]);
 
        $response = [
          'success' => true,
          'data' => $store,
          'msg' => "Cropped image successfully uploaded"
         ];
        return $this->response->setJSON($response);
    }    
}
Step 5 : Define Route

This step shares with you about creating a route with the GET method to bring image crop component in view, so head over to app/Config/Routes.php file and append the following route code:

$routes->get('/crop-image', 'ImageCrop::index');
Step 6 : Setting Up Codeigniter View

Further, head over to the app/Views directory; inside here, you need to create a home.php file. This file will invoke the view for image upload and crop component, also add the following code in app/Views/home.php file:

        $(document).ready(function () {

                enableExif: true,
                viewport: {
                    width: 220,
                    height: 220,

            });

            $('#img-crop').on('change', function () {
                var reader = new FileReader();
                reader.onload = function (event) {
                    $image_crop.croppie('bind', {
                        url: event.target.result
                    }).then(function () {
                        
                    });
                }
                reader.readAsDataURL(this.files[0]);
                $('#imageModel').modal('show');
            });

            $('.crop_my_image').click(function (event) {
                $image_crop.croppie('result', {
                    type: 'canvas',
                    size: 'viewport'
                }).then(function (response) {
                    $.ajax({

                        data: {
                            "image": response
                        },
                        success: function (data) {
                            console.log(data);
                            $('#imageModel').modal('hide');
                        }
                    })
                });
            });
        });
    </script>
</body>

php spark serve

Then next run the url in your browser.

http://localhost:8080/crop-image
