In this tutorial, we will learn how to crop and resize an image before saving it in Codeigniter 4 using jQuery Croppie. Croppie is an easy to use javascript image cropper. It is very easy to use and provides a great user experience.
We will use jQuery Croppie to crop and resize an image before saving it in Codeigniter 4. We will also use the jQuery AJAX library to send the cropped image data to the server.
We will create a simple form with an image upload field. When the user selects an image, we will display the image in a Croppie instance. The user can then crop and resize the image before submitting the form.
We will then use the jQuery AJAX library to send the cropped image data to the server. On the server side, we will use the Codeigniter 4 Image Library to save the cropped image.
So let’s get started.
Step 1: Create a Codeigniter 4 Project
First, we need to create a Codeigniter 4 project. If you don’t already have one, you can create one using the following command:
composer create-project codeigniter4/appstarter
Step 2: Install jQuery and jQuery Croppie
Next, we need to install jQuery and jQuery Croppie. We can do this by downloading the latest version of jQuery and jQuery Croppie from their respective websites.
Once downloaded, we need to include the jQuery and jQuery Croppie files in our project. We can do this by adding the following code to the head section of our project’s main layout file:
Step 3: Create a Form
Next, we need to create a form with an image upload field. We can do this by adding the following code to our project’s main layout file:
Step 4: Initialize jQuery Croppie
Next, we need to initialize jQuery Croppie. We can do this by adding the following code to our project’s main layout file:
Step 5: Handle Image Upload
Next, we need to handle the image upload. We can do this by adding the following code to our project’s main layout file:
Step 6: Handle Image Crop
Next, we need to handle the image crop. We can do this by adding the following code to our project’s main layout file:
Step 7: Save the Cropped Image
Finally, we need to save the cropped image. We can do this by adding the following code to our project’s main layout file:
input->post(‘image’)){ $image = $this->input->post(‘image’); $imageName = time().’_cropped.png’; $config[‘image_library’] = ‘gd2’; $config[‘source_image’] = $image; $config[‘new_image’] = ‘./uploads/’.$imageName; $config[‘maintain_ratio’] = FALSE; $config[‘width’] = 200; $config[‘height’] = 200; $this->load->library(‘image_lib’, $config); $this->image_lib->resize(); } ?>
And that’s it! We have successfully implemented image crop and resize before save in Codeigniter 4 using jQuery Croppie.

To crop & resize and save images using jQuery croppie with ajax in ci 4; In this tutorial, we will show you how to crop and resize images before uploading/saving to the database & directories in CodeIgniter using jQuery Croppie with ajax.
Codeigniter 4 Crop & Save Image using jQuery Croppie Example Tutorial
Use the below-given steps to crop, resize and save images using jquery with ajax in PHP CodeIgniter:
- Step 1: Download Codeigniter Project
- Step 2: Basic Configurations
- Step 3: Create a Database With Table
- Step 4: Setup Database Credentials
- Step 5: Create a Controller
- Step 6: Create a View
- Step 7: Start the Development server
Step 1: Download Codeigniter Project
In this step, we will download the latest version of Codeigniter 4, Go to this link https://codeigniter.com/download Download Codeigniter 4 fresh new setup and unzip the setup in your local system xampp/htdocs/ . And change the download folder name “demo”
Step 2: Basic Configurations
Next, we will set 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 a Database With Table
In this step, we need to create a database name demo, so open PHPMyAdmin and create the database with the name demo. After successfully create a database, you can use the below SQL query for creating a crop_images table in your database.
CREATE TABLE crop_images (
id int(11) NOT NULL AUTO_INCREMENT COMMENT 'Primary Key',
title varchar(100) NOT NULL COMMENT 'Title',
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
In this step, we need to connect our project to the database. we need to go app/Config/Database.php and open database.php file in text editor. After opening the file in a text editor, We need to set up database credentials in this file like below.
public $default = [
'DSN' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'demo',
'DBDriver' => 'MySQLi',
'DBPrefix' => '',
'pConnect' => false,
'DBDebug' => (ENVIRONMENT !== 'production'),
'cacheOn' => false,
'cacheDir' => '',
'charset' => 'utf8',
'DBCollat' => 'utf8_general_ci',
'swapPre' => '',
'encrypt' => false,
'compress' => false,
'strictOn' => false,
'failover' => [],
'port' => 3306,
];
Step 5: Create a Controller
Now Go to app/Controllers and create a controller name CropImageUpload.php. In this controller, we will create some method/function:
- Index() – This is used to display crop image before upload form.
- Store() – This is used to validate form file/image on server-side and store crop image into MySQL database and folder.
<?php namespace App\Controllers;
use CodeIgniter\Controller;
class CropImageUpload extends Controller
{
public function index()
{
return view('crop-image-upload-form');
}
public function store()
{
helper(['form', 'url']);
$db = \Config\Database::connect();
$builder = $db->table('crop_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);
}
}
Step 6: Create a View
Now we need to create crop-image-upload-form.php, go to application/views/ folder and create crop-image-upload-form.php file. and update the following HTML into your files:
<html>
<head>
<title>jQuery Croppie Image Upload Crop Codeigniter 4</title>

<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</script>
Add this jQuery croppie plugin libaray into crop-image-upload-form.php file:
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js"></script

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/croppie/2.6.5/croppie.css" />
Then, add this below code into crop-image-upload-form.php file to crop image before upload on boostrap model in codeigniter:
$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');
});
Also, add this below ajax code in crop-image-upload-form.php for upload crop image into controller file in codeigniter 4 projects:
$('.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',
