Hi,

I’m trying to upload a file using postman ([following the docs](https://www.slimframework.com/docs/v4/cookbook/uploading-files.html)) and I’m getting an error at this line:

` $directory = $this->get('upload_directory');`

I expect this relates to the container, in my settings file I have this:

`//Upload directory`  
`$settings['upload_directory'] = $settings['root'] . '/uploads';`

**How can I get the `upload_directory` into my `__invoke` method?**

**Also is `UPLOAD_ERR_OK` defined anywhere, doesn’t look like it. How/where should this be defined?**

```
public function __invoke(ServerRequestInterface $request, ResponseInterface $response, array $args): ResponseInterface
{

    $supplier = (string)$args['supplier'];

    $responseData = ['supplier' => $supplier];

    $directory = $this->get('upload_directory');
    $uploadedFiles = $request->getUploadedFiles();

    // handle single input with single file upload
    $uploadedFile = $uploadedFiles['supplier'];
    if ($uploadedFile->getError() === UPLOAD_ERR_OK) {
        $filename = $this->moveUploadedFile($directory, $uploadedFile);
        $responseData = [
            'filename' => $filename,
            'supplier' => $supplier,
            'message' => 'File uploaded'
        ];
        //$response->getBody()->write('Uploaded: ' . $filename . '<br/>');
    }

    // Invoke the Responder and pass in the response and responseData ($responseData)
    return $this->responder->withJson($response, $responseData);

}
```

The Slim documentation shows an example of retrieving the settings inside a route callback (closure).

If you want to retrieve the settings inside a class, you may better pass the settings via the constructor. Here you can find a tutorial: [Slim 4 - Configuration](https://odan.github.io/2021/03/21/slim4-laminas-config.html).

The `UPLOAD_ERR_OK` constant is a native PHP constant. You don’t have to define it, it’s already defined. See here: [Error Messages Explained](https://www.php.net/manual/en/features.file-upload.errors.php#features.file-upload.errors)

Awesome, thank you so much! I’ll take a look at that.
