I try to make a file input working by using the documentation:

> **[Form - 4.x](https://book.cakephp.org/4/en/views/helpers/form.html#creating-file-inputs)**
>
> The FormHelper focuses on creating forms quickly, in a way that will streamline validation, re-population and layout.

and it gives the error

> Use of undefined constant UPLOAD\_DIRECTORY - assumed ‘UPLOAD\_DIRECTORY’

I can understand that if ‘’ is assumed, this may explain the following error:

```
Argument 1 passed to Cake\Http\Session::_overwrite() must be of the type array, null given

```

I also assume the documentation is correct 🙂 although not explicetely mentioned, I used  
`use UploadedFileInterface;` in the Controller that produces the error:

public function add()  
{

```
    $gpxFile = $this->GpxFiles->newEmptyEntity();
    if ($this->request->is('post')) {
       $gpxFile = $this->GpxFiles->patchEntity($gpxFile, $this->request->getData());
		
		$gpx = $this->request->getData('gpx');
		debug($gpx);
		$destination = UPLOAD_DIRECTORY . $gpxFile->user_id . $gpx->getClientFilename();

		// Existing files with the same name will be replaced.
		$gpx->moveTo($destination);
		
		$gpxFile->name=$gpx->getClientFilename();

```

Is this a real issue or something I overlooked / what is missing in the documentation?

My hunch is that `UPLOAD_DIRECTORY` is used in the documentation to indicate that it’s a constant that _you_ need to supply somewhere.
