The form component should now guarantee to always pass an UploadedFile object to your model. There you can call getOriginalName() to retrieve the original name of the uploaded file. For security reasons, the real file name is a generated hash value.
The extension classes are now the only constructor argument of the FormFactory class. They replace the existing "type loader" classes.
new FormFactory(array(
new CoreExtension($validator, $storage),
new CsrfExtension($csrfProvider),
new DoctrineOrmExtension($em),
));
Together with a few upcoming commits this mechanism will make
* extension of the form framework in bundles and
* usage of the forms outside of Symfony2
much easier.
The data can now be passed to all creation methods:
$form = $factory->create('form', $data);
By default, a form will receive the name of its type ("form" in above example). If you wish to pass a custom name, use createNamed():
$form = $factory->createNamed('form', 'myform', $data);
