        helper(['form', 'url']);
         
        $validated = $this->validate([
            'file' => [
                'uploaded[file]',
                'mime_in[file,image/jpg,image/jpeg,image/gif,image/png]',
                'max_size[file,4096]',
            ],
        ]);
 
        $msg = 'Please select a valid file';
  
        if ($validated) {
            $avatar = $this->request->getFile('file');
            $avatar->move(WRITEPATH . 'uploads');
 
            $data = [
                'name' =>  $avatar->getClientName(),
                'type'  => $avatar->getClientMimeType()
            ];
 
            $s3Client = new S3Client([
                'version' => 'latest',
                'region'  => 'YOUR_AWS_REGION',
                'credentials' => [
                    'key'    => 'ACCESS_KEY_ID',
                    'secret' => 'SECRET_ACCESS_KEY'
                ]
            ]);
 
            $bucket = 'YOUR_BUCKET_NAME';
            $file_Path = __DIR__ . '/uploads/'. $filename;
            $key = basename($file_Path);
 
            try {
                $result = $s3Client->putObject([
                    'Bucket' => $bucket,
                    'Key'    => $key,
                    'Body'   => fopen($file_Path, 'r'),
                    'ACL'    => 'public-read', // make file 'public'

        }
 
        return redirect()->to( base_url('public/index.php/form') )->with('msg', $msg);
