- Index() – This is used to display file/image upload form.
- Store() – This is used to validate form file/image on server-side and store into MySQL database and folder.
<?php namespace App\Controllers;
use CodeIgniter\Controller;
require 'vendor/autoload.php';
use Aws\S3\S3Client;
class Form extends Controller
{
public function index()
{
return view('form');
}
public function store()
{
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()
];
// Instantiate an Amazon S3 client.
$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'
]);
$msg = 'File has been uploaded';
} catch (Aws\S3\Exception\S3Exception $e) {
//$msg = 'File has been uploaded';
echo $e->getMessage();
}
$msg = 'File has been uploaded';
}
return redirect()->to( base_url('public/index.php/form') )->with('msg', $msg);
}
}
Important Note:- Please add your aws bucket key, secret, region and bucket name in the controller file.
Step 6 – Create Views

<html>
<head>
