How to upload a image using Slim Framework - php

Question

I want to storage a image in server and save the path in MySQL, but i'm not finding a good code to do it.
I found this, but does not work:
$container = $app->getContainer();
$container['upload_directory'] = __DIR__ . '../uploads';
$app->post('/photo', function (Request $request, Response $response) use ($app) {
$directory = $this->get('upload_directory');
$uploadedFiles = $request->getUploadedFiles();
$uploadedFile = $uploadedFiles['picture'];
if($uploadedFile->getError() === UPLOAD_ERR_OK) {
$filename = moveUploadedFile($directory, $uploadedFile);
$response->write('uploaded ' . $filename . '<br/>');
}
});
function moveUploadedFile($directory, UploadedFile $uploadedFile){
$extension = pathinfo($uploadedFile->getClientFilename(),
PATHINFO_EXTENSION);
$basename = bin2hex(random_bytes(8));
$filename = sprintf('%s.%0.8s', $basename, $extension);
$uploadedFile->moveTo($directory . DIRECTORY_SEPARATOR . $filename);
return $filename;
}
Somebody knows how to upload image and save the path in MySQL?

Answer 1

First you need a database connection for MySQL. Read more
Then create a table, e.g. files(id, path, filename)
To insert the record (after the upload) into the table, you could use an SQL statement as follows:
// ...
$filename = moveUploadedFile($directory, $uploadedFile);
$response->getBody()->write('File uploaded: ' . $filename);
$row = [
'path' => $directory,
'filename' => $filename
];
$sql = "INSERT INTO files SET path=:path, filename=:filename;";
$pdo->prepare($sql)->execute($row);
// ...
return $response;
Please note that $response->write('...') will not work. It must be $response->getBody()->write('my content');.
Edit: Make sure that the uploads/ directory exists and the directory has write access. For example chmod -R 1777 uploads/
