Plugin for easily managing filesystem related operations based on SPL. |
Image manipulation is now fully supported through the great sfImageTransformPlugin: http://symfony-project.org/plugins/sfImageTransformPlugin
Unit test rewrite to cover core functionalities, more to come until release of v1.0
Bugfixes in core operations (file and directory copying)
chmod(), chown(), chgrp() and improved array access handling.
2009/09/29 Fixed a bug in path detection when accessing a file by giving an absolute pathname under windows.
2009/09/18 Fixed a few minor issues, path handling on windows, utility methods and so on...
Recently worked on cross brower stuff, mainly IE (yes! ;)). So fixed some bug in SWFUploadPlugin and Ext-Tree.
Finally added support for a multi-file uploader based on SWFUpload. I've been re-written the whole queue plugin, so this thing is yet in (cross browser) test state. Please give me a hint if this part of the code runs on lynx, too.
sfFilebasePlugin provides an unified api for filesystem related operations with focus on web based applications (yes, really.)
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)
The core plugin consists of a set of classes based on built in SPL classes (SplFileInfo/ -Object, DirectoryIterator ...) written by Marcus Boerger. Documentation for these base classes may be found in the API-docs.
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.
The git repos also contains a sample symfony project which shows a few features.

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.
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.
Note: SfFilebasePlugin has only been tested on Symfony 1.2. It probably works fine with 1.1/1.0, but i'm not sure about it. I'll run some tests, but has actually no priority to me. Please send me an email if you want to use sfFilebasePlugin on a lower Version than 1.2.
Note: If the GD library is not activated, you might
have to uncomment the related line in your php.ini and restart your web
server to enable PHP image handling functions.
Note: To use !ImageMagick, you'll need to install the pecl imagick extension. On debian/ubuntu, do something like
sudo apt-get install php5-imagick
On Windows, you'll probably have to activate the extension in your php.ini.
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, but it will be installed as a pear dependency when you install sfFilebasePlugin by typing
symfony plugin:install sfFilebasePlugin
For getting doctrine 1.1 working instead of the native doctrine 1.0 version which is embedded within sfDoctrinePlugin, you have to add the following line to your /config/ProjectConfiguration.class.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.
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:
all:
sf_filebase_plugin:
path_name: /home/joshi/www/test/web/uploads/assets
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.
Now switch to your shell window 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:
http://yourhost/frontend_dev.php/sf_filebase_file
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.
To use sfFilebasePluginWebRequest as an enhancement of sfWebRequest, write the following lines in your apps/myapp/factories.yml:
all:
request:
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 user sfFilebasePluginWebRequest, call
public function executeMyAction(sfWebRequest $request)
{
$filebase = new sfFilebasePlugin();
$files = $filebase->getUploadedFiles();
}
There is also a factory method that stores filebase instances:
$filebase = sfFilebasePlugin::getInstance()
This way retrieving a filebase is somewhat "best practice", but the constructor remains public due to backwards compatiblilty.
Create a new sfFilebasePlugin in sf_project/web/uploads (this folder is set by reading sfConfig::get('sf_upload_dir') internally per default)
sfFilebasePlugin::getInstance()
To change the default location of the filebase directory go to apps/my_app/config/app.yml and write for example:
env:
sf_filebase_plugin:
path_name: /path/to/filebase
cache_directory: /path/to/cache
With this, you can specify different directories for your environments. But be careful while synchronizing files with e.g. a database, here it can easily come to out of synch errors.
It is a good practice to encapsulate file operations in transactions when you log them into a database.
You must consider for yourself if the filebase directory may be accessible via browser (then it must lie within your servers' document root) or not - perhaps due to security issues. It is really simple to passthru files by php and sync them e.g. with a database and a permission management by using transactions.
Creating a new filebase, using a custom directory, directly from your application:
$filebase = sfFilebasePlugin::getInstance('/var/www/my_filebase_dir');
You can also specifiy the location of the cache directory:
$filebase = sfFilebasePlugin::getInstance(
'/var/www/my_filebase_dir',
'/temp'
);
Note: The initial paths must be absolute from filesystem root.
Note: The sfFilebasePlugin "root"-directory must be writable by php. In
standard php configurations with mod_php you usually have to chmod(777) it or
change the ownership to wwwrun or something like that.
foreach($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
$file->copy('my_new_filename.ext');
$file->copy('/path/to/folder/in/filebase/filename.ext');
$file->copy($filebase->getFilebaseFile('my_folder/file.ext'));
}
// do something with the thumbnails.
$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 ;)
// 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(
$filebase->getFilebaseFile('dirname');
);
$destination_directory = "my_uploads";
$files = $filebase->getUploadedFiles();
$filebase->moveUploadedFile($files[0], $destination_directory);
// Or by handling all uploaded files:
$filebase->moveAllUploadedFiles($destination_directory);
Using the sfFilebasePluginValidatorFile is as simple as using the generic sfValidatorFile class. For example you could do the following:
$form = new myForm()
$this->upload_form->bind($request->getParameter('upload'),
$request->getUploadedFiles('upload'));
if($this->upload_form->isValid())
{
// 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)
{
$file->rotate('20');
}
}
}
....
If you are using sfFilebasePluginValidatorFile within the admin/crud generator, you probably have to implement some logic into your child-class of sfFormPropel or sfFormDoctrine.
You won't have to specify a $path any more. Although you could do it, the as default path now the root dir is taken that you have had defined in your app.yml (see above).
SfFilebasePluginValidatorFile now takes a new option, "allow_overwrite". If you set this option to false (default is true), then your form throws a new sfValidatorError when the uploaded file already exists in file system.
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
You may find the behavior class files in the plugins lib directory, under lib/doctrine/template. Usage is simple:
testerer:
tableName: tester
actAs:
File:
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
Doctrine::getTable('testerer')->find(1)->getFile();
// And vice-versa
Doctrine::getTable('testerer')->find(1)->setFile('path/to/file');
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:
Better symfony-integration
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.
