About
-----

[](#about)

Sanitizes the filenames of files uploaded via the Contao file manager or Contao form. [Read more](https://www.numero2.de/contao/erweiterungen/proper-filenames.html)

System requirements
-------------------

[](#system-requirements)

- [Contao 4.13 or newer](https://github.com/contao/contao)

Installation & Configuration
--------------------------------

[](#installation--configuration)

- Install via Contao Manager or Composer (`composer require numero2/contao-proper-filenames`)
- In the Backend go to `System Settings` and click `Check filenames` under `Upload settings`
- Configure how the filenames should be renamed by choosing an option from `Valid filename characters`

Commands
--------

[](#commands)

Recursively sanitize all files and folders in a given directory.

```
contao-console contao:proper-filenames:sanitize myfolder -r
```

The extension only analyzes files that are stored in Contao's DBAFS (tl\_files). The DBAFS should be synchronized before the call - either via the `File manager` in the Backend or with the following console call:

```
contao-console contao:filesync
```

To get a preview of how everything will be renamed there is also a `--dry-run` flag. For all available flags and options see the help using `contao-console contao:proper-filenames:sanitize --help`.
