Hello Friends,

Now let's see example of how to use image rotate, upload and integration using image manipulation in codeigniter 4. This is a short guide on codeigniter 4 if image rotate, upload and integration using image manipulation. We will use how to use image rotate, upload and integration using image manipulation using in codeigniter 4. Let's get started with how to image rotate, upload and integration using image manipulation use in codeigniter 4.

Here i will give you many example how you can use image rotate, upload and integration using image manipulation in codeigniter 4.

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

composer create-project codeigniter4/appstarter

This step is optional, you can activate the error debugging. You need to go to app/Config/Boot/development.php likewise app/Config/Boot/production.php files and carefully switch the display_errors property to 1 from 0.

ini_set('display_errors', '1');

In this is step we need to create a new table and insert few record.

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',
    PRIMARY KEY (id)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 COMMENT='files table' AUTO_INCREMENT=1;

In this segment, you have to open the app/Config/Database.php and add the database name, username, and password in the $default array.

Path: app/Config/Database.php

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

Sometimes, you might face following error:

Unable to connect database: Codeigniter;

To fix this error, you need to define the hostname based on your localhost development server.

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

# ====== XAMP
public $default = [ 
  'hostname' => '/Applications/XAMPP/xamppfiles/var/mysql/mysql.sock',
]

Subsequently, you have to create a brand new file in the app/Controllers folder, and It might be named ImgManipulationController.php

Furthermore, go to app/Controllers/ImgManipulationController.php and add the given code recklessly.

<?php
namespace App\Controllers; 
use CodeIgniter\Controller;
    
class ImgManipulationController extends Controller 
{
   public function index() { 
      return view('image');
   }
    
   public function upload() 
   {     
        helper(['form', 'url']); 
        // 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]',
            ]
        ]);
        
        if (!$isValidFile) {
            print_r('Upload valid file or image size should be upto 4mb');
        } else {
            $imgPath = $this->request->getFile('file');

            // Image manipulation
            $image = \Config\Services::image()
                        ->withFile($imgPath)
                        ->fit(150, 150, 'left')
                        ->rotate(90)
                        ->save(FCPATH .'/thumbnails/'. $imgPath->getRandomName());

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

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

            $store = $db->insert($fileData);
            print_r('File successfully uploaded.');
        } 
   }
} 
?>

To make the file upload template your default view, you need to define the route for that, ensure that you update the following code in the app/Config/Routes.php file.

Path: app/Config/Routes.php

$routes->setDefaultController('ImgManipulationController');
$routes->get('/', 'ImgManipulationController::index');

Ultimately, we have landed on the final step of this tutorial, and we need to set up a new view, so create the image.php file in the app/Views folder. Thereafter, open and update the app/Views/image.php file.

Path: app/Views/image.php

    </div>

Now, start the Codeigniter project, moreover execute the given url on the browser to view the app in the browser.

php spark serve

Then next run the url in your browser.

http://localhost:8080

It will help you....
