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);
