Step 2: Basic Configurations
Step 3: Create Database With Table
Step 4: Setup Database Credentials
Step 5: Create Image Resize Controller
Step 6: Create Image Upload Form View
Step 7: Start Development server

Step 1: Setup Codeigniter Project

In this step, you 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, you 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 Database With Table

In this step, you 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 files(
    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

In this step, you need to connect our project to the database. So, visit app/Config/Database.php and open database.php file in text editor. After opening the file in a text editor, YOU 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 Image Resize Controller

In this step, Go to app/Controllers and create a controller name ImageUploadController.php. Then add the following code into it:

<?php

namespace App\Controllers; 
use CodeIgniter\Controller;
    
class ImageUploadController extends Controller {

   public function index() { 
      return view('imageUploadForm');
   }
    
   public function upload() {
        helper(['form', 'url']); 

        // access database
        $database = \Config\Database::connect();
        $db = $database->table('files');
    
        // file validation
        $isValidFile = $this->validate([
            'file' => [
                'uploaded[file]',
                'mime_in[file,image/jpg,image/jpeg,image/png,image/gif]',
                'max_size[file,4096]',
            ]
        ]);
        
        // check validation
        if (!$isValidFile) {
            print_r('Upload valid file upto 4mb size');
        } else {
            $imgPath = $this->request->getFile('file');

            // Image manipulation
            $image = \Config\Services::image()
                ->withFile($imgPath)
                ->resize(200, 100, true, 'height')
                ->save(FCPATH .'/images/'. $imgPath->getRandomName());

            $imgPath->move(WRITEPATH . 'uploads');

            $fileData = [
                'name' =>  $imgPath->getName(),
                'type'  => $imgPath->getClientMimeType()
            ];

            $store = $db->insert($fileData);
            print_r('Image has been successfully resized');
        } 
   }


} ?>

Step 6: Create Image Upload Form View

In this step, you need to create imageUploadForm.php, go to application/views/ directory and create imageUploadFormphp file. and update the following HTML into your files:

<!DOCTYPE html>
<html> 
<head> 
  <title>Codeigniter Compress Image Size Example - Tutsmake.com</title> 
</head>
  
<body> 
   
  <?php echo $error;?> 
     
  <form method='post' action='/ImageUploadController/upload' enctype='multipart/form-data'>
     <input type="file" name="file" size="20" />
     <input type="submit" value="upload" /> 
  </form> 
   
</body>
</html>

Step 7: Start Development server

For start development server, open your terminal and execute the following command it:
