sfFilebasePlugin provides an unified api for filesystem related operations with focus on web based applications (yes, really.)

sfFilebasePlugin provides a wrapper for doing image manipulations very easily. For that, sfFilebasePlugin uses the great image manipulation capabilities of sfImageTransformPlugin (http://symfony-project.org/plugins/sfImageTransformPlugin).

There are also helpers that provide easy access to uploaded files, an uploaded file validator, a SfWebRequest child class for transforming the $__FILES array into a more accessible structure and a few other features that simplify upload handling.

sfFilebasePlugin provides as doctrine behaviour to easily connect your systems files with a database.

Additionally, there is a admin module and a simple to use component to render a drag'n'drop treeview based on ext js for most simply organizing your files in a directory structure, all maintained through a doctrine driven hierarchical database. (Still in developement, but at meantime rather stable)

In connection with sfWidgetFormInputSwfUpload you can perform multi file uploads within a few quick steps.

The core plugin consists of a set of classes based on built in SPL classes (SplFileInfo/ -Object, DirectoryIterator ...) written by Marcus Boerger.

The api-documentation for these base classes may be found in http://www.php.net/helly/php/ext/spl/.

The API Documentation for sfFilebasePlugin can be found in ./plugins/sfFilebasePlugin/doc. The API doc is not included in the pear- package, so you'll have had to browse the svn-repository http://svn.symfony-project.com/plugins/sfFilebasePlugin/ or my github-repository [http://github.com/joshiausdemwald/sfFilebasePlugin](http://github.com/joshiausdemwald/sfFilebasePlugin which i use to store what i am working on.

The git repos also contains a sample symfony project which shows a few features. It could also be used as additional documentation material.

SfFilebasePlugin extends the built in SPL-Classes by dissociating more and different files or types. Resulting in a collection of classes like sfFilebasePluginDirectory or sfFilebasePluginImage, sfFilebasePluginThumbnail. I am planning sfFilebasePluginZIP or something like that - further enrichments that "fit" into sfFilebasePlugin. Additionally, the plugin provides an extension of SplFileObject named sfFilebasePluginFileObject.

SfFilebasePlugin can help woman if she wants to

  • control file uploads,

  • search and retrieve files from her servers' filesystem,

  • read/write/execute files,

  • do (eventually architecture dependent) filesystem operations like chmod, mkdir, touch.

  • easily convert path names from absolute to relative, web root based or filebase root based. Each file related plugin method has an overloaded signature, so that it does not matter whether you pass an absolute, relative pathname or an instance of sfFilebasePluginFile or one of its children.

  • manipulate images or generate thumbnails (based on the great sfImageTransformPlugin. Included is a hidden cache layer which automatically stores generated binary data if you want to do so.

Image manipulation capabilities

As of Version >= 0.9, sfFilebasePlugin uses the image transform capabilities of sfImageTransformPlugin to perform image manipulation. So refer to the plugin documentation of sfImageTransformPlugin to see what you are able to accomplish.


(Install instructions taken from README in sfThumbnailPlugin, (c) Fabien Potencier)

To install the plugin for a symfony project, the usual process is to use the symfony command line.

With symfony 1.0, use:

$ symfony plugin-install http://plugins.symfony-project.com/sfFilebasePlugin

With symfony 1.1/1.2, use:

$ symfony plugin:install sfFilebasePlugin

Alternatively, if you don't have PEAR installed, you can download the latest package attached to this plugin's wiki page and extract it under your project's plugins/ directory.

Clear the cache to enable the autoloading to find the new classes:

$ php symfony cc

You're done.

Adminstration area install instructions (optional)

SfFilebasePlugin provides frontend modules for easy adminstration of your files and directories (in developement progress yet).

The administration area uses the ExtJs (http://extjs.com/) to render some fancy widgets like a tree view of your directory/file structure. With this you are able to drag and drop files or whole directory structures within your filebase with just a click on your mouse button.

This makes organizing your files and assets really easy.

These modules require doctrine >= 1.1 to be installed.

Doctrine 1.1 is not shipped with symfony 1.2, so you will have to download the appropriate libaries and link it within your config/projectConfiguration.php:

sfConfig::set('sfDoctrinePlugin_doctrine_lib_path', sfConfig::get('sf_plugins_dir') . '/Doctrine/lib/Doctrine.php');

Alternatively you can install doctrine 1.1 with your symfony 1.2 project by following the instructions behind this link: http://www.symfony-project.org/blog/2009/01/12/call-the-expert-using-a-custom-version-of-doctrine.

Setting up your application

The adminstration modules of sfFilebasePlugin can handle files and directories, even your database tables dependent of your application and environment settings.

The following part presumes that you have had already setup your database properly.

To init the administration module, first create an empty application:

symfony generate::app frontend

After that, enable the sfFilebasePlugin modules in your /apps/frontend/config/settings.yml:

enabled_modules:        [default, sf_filebase_directory, sf_filebase_file, sf_filebase_filedeliverer, sf_filebase_overview]

Now set up the directory the files should be stored (optional, per default the /web/upload directory is taken). In /apps/frontend/config/app.yml, write:

        path_name: path/to/your/upload/directory

You can create as much instances of a filebase as you want to, but this will be your default filebase which is used by the modules and doctrine models to store uploaded files in. If you don't specify a filebase directory in app.yml, web/uploads will be used.

Now open a CLI and type:

symfony sfFilebase:create-root frontend

If you want to initially import some files into your sfFilebase, optinally type the following line:

symfony sfFilebase:import application /path/to/your/files --env="prod"

symfony sfFilebase:import frontend /path/to/your/files --env="your_env"

// Default environment is "dev"
symfony sfFilebase:import frontend /path/to/your/files

That's it. You can now browse to your filebase by typing:


Have fun ;)


The plugin contains a set of classes, that are all instanciated by a file controller called sfFilebasePlugin. Please take a look at the examples, the sample project available at githup and the phpdocs to see how it works. There is a static utility class named sfFilebasePluginUtil that provides general worker methods.

There are also a few classes that integrates sfFilebasePlugin into symfony. There is a helper file to use the filebase in your views, and there is also an sfFilebasePluginWebRequest class, that may replace the core symfony sfWebRequest class, but this is not a "must have". If you want to do so, the $request variable passed to your actions contains some additional methods to retrieve uploaded files (there is the original sfWebRequest::getFiles() which returns a cleaned up file array and - with sfFilebasePluginWebRequest::getUploadedFiles() a new way to retrieve uploaded files in an object oriented way as instances of sfFilebasePluginUploadedFile.


There is a sample project at github: http://github.com/joshiausdemwald/sfFilebasePlugin

Simply use this project to test sfFilebasePlugin, or create a new project, copy the apps-folder, thats it (i think). You'll see some forms, can upload files, create directories and see some image transformations in action. Perhaps it can be useful.

Short code samples

To use sfFilebasePluginWebRequest as an enhancement of sfWebRequest, write the following lines in your apps/myapp/factories.yml:

    class: sfFilebasePluginWebRequest

If you are done, you can retrieve uploaded files by calling in your action:

public function executeMyAction(sfWebRequest $request)
  $files = $request->getUploadedFiles();

Alternatively and if you don't want to use sfFilebasePluginWebRequest, call

public function executeMyAction(sfWebRequest $request)
  $filebase = new sfFilebasePlugin();
  $files = $filebase->getUploadedFiles();

Iterate over sub-directories:

foreach($filebase AS $file)
   //lets create thumbnails for all images
   $thumbnails = array();
   if($file instanceof sfFilebasePluginImage)
     $thumbnails[] = $file->getThumbnail(array('width'=>120));

   // Make a few stupid things to show up
// do something with the thumbnails.

Fetch some Files that exists in file system (the short way):

$file = $filebase['myfile.txt'];

// open the file
$pointer = $file->openFile();

// read some content:
echo $pointer->fileGetContents();

// Retrieve a directory:
$dir = $filebase['path/to/mydir'];

// Retrieve an image from this directory:
$image = $dir['image.jpg'];

// Create a thumbnail:
$tn = $image->getThumbnail($width, $height);

// .... and so on ;)

Deal with "virtual" files, that does not exist in file system:

// Throws an error, so how to achieve this?
$file = $filebase['path/to/nonexistent/file.txt'];

// The correct way:
$file = $filebase->getFilebaseFile('path/to/file');

// Or:
$file = $filebase->getFilebaseFile('/absolute/path.txt');

// Or:
$file = $filebase->getFilebaseFile($another_instance_of_filebase_file);

Note that despite you are awaiting an directory, a file, a link or an image, the system cant determin it's file type unless the file physicall exists in file system. So be aware of this!

You can also create new files on the fly, using sfFilebasePlugin methods:

$new_dir = $filebase->mkDir('/path/to/dir');

$absolute_new_dir = $filebase->mkDir('/absolute/path/to/dir');

$new_dir_from_instance = $filebase->mkDir(


$destination_directory = "my_uploads";
$files = $filebase->getUploadedFiles();
$filebase->moveUploadedFile($files[0], $destination_directory);

// Or by handling all uploaded files:

Using the sfFilebasePluginValidatorFile is as simple as using the generic sfValidatorFile class. For example you could do the following:

$form = new myForm()
  // retrieve all files that have been uploaded
  $files = $this->upload_form->getValue('files');

  // Loop and save them in a folder that is located in
  // /path/to/filebase/my_uploads.
  // 'my_uploads' may also be an instance of sfFilebasePluginFile
  // or an absolute path.
  foreach($files AS $file)
    $file = $file->moveUploadedFile('my_uploads');
    if($file instanceof sfFilebasePluginImage)
      // DO SOMETHING WITH THE sfImageTransformPlugin-METHODS:
      $file->thumbnail(100, 100)->save();

Image Manipulation

Every instance of sfFilebasePluginImage implement the same physical methods as sfFile, the image manipulation base class of sfImageTransformPlugin. Additionally you can use every virtual method to do transforms, so e.g. $myImage->thumbnail(200,200) works as expected. For further documentation refer to the manual of sfImageTransformPlugin

Doctrine behaviour

You may find the behavior class files in the plugins lib directory, under lib/doctrine/template. Usage is simple:

  tableName: tester
      name: path_name
      filebaseDirectory: <?php echo dirname(__FILE__)?>/../../test/assets
      checkExistence: true

As you can see, woman creates a table named tester and object model "testerer". The behaviour adds a column named "path_name", and a filebase "root" directory must also be provided (you may use the one configured within your app.yml, too).

Then fetching a tuple, simply do the following:

// Retrieves the corresponding sfFilebasePluginFile instance

// And vice-versa

If checkExistence key isset to true, your doctrine built-in validation checks if the file really exists in your filesystem before persisting the tuple into your database.


The above code is incomplete because it does not show any error handling. SfFilebasePlugin handles errors by insanely throwing sfFilebasePluginException that can be caught for merely any operation. Please give me a hint if you think that there is an exception that makes no sense in the context or if you miss one in another part of the code or this particular runtime situation.


SfFilebasePlugin is in developement state. Standard methods to deal with files are meant to be stable, but there is space for a lot of improvements. Code contributions and -improvements, error reportings as bugfixes are very welcomed!


I'd love to see some file compression support in the sfFilebasePlugin - but i think at the moment it'd be better to work on improving stability and testing.

This plugin is ideal if you want to have a solid "virtual filesystem" in a new project and you are also willing to improve and fix it while coding as well as optimizing the api for usability. That's what agile devopement is meant to be ;););).

There are a few concrete features that i have in mind for the near future:

  • Improving unit and functional tests
  • Bug tracking and fixing
  • Better symfony-integration

    • Integration in sfForms as an alternative to sfValidatorFile, or perhaps a combination of both
    • Image processing: There are two adapters, one for imagick extension (no system calls like in sfThumbnailPlugin, but i simply don't know what is the better way doing it) and GD. This is redundant, because sfThumbnailPlugin also provides 2 adapters. Perhaps integrate it as a plugin-dependancy?
    • More, More, More! Image processing capabilities (experimental rotation is built in, perhaps a web2.0 mirror effect or something like this)


I began to write some unit-tests on it, but they do not fit in every aspect. So if you want to report a bug, i would appreciate if you'd pass unit or functional tests that reproduce the issue.

Please note that sfFilebasePlugin was developed on a linux machine running ubuntu and php5.2.6 and symfony 1.2. It should run on similar platforms, too, but i did not test it.

Tests should also consider other operating systems like (what was its name? ahhh, got it:) windows and rich man's MacOS.

Ok, i hope that this plugin is useful, i'd love to receive your comments and critiques.

Have fun ;)


Thanks to Marcus Börger for initializing the gread SPL extension. And to the ext js team for creating the most powerul but simple to use tree view control. Thank you, i would not manage to do such things in months.
