ad (1): HTML4 "id" attributes are limited to strings starting with a letter and containing only letters, digits, underscores, hyphens, periods and colons.
ad (2): Property paths contain three special characters needed for correct parsing: left/right bracket and period.
The rules for form naming are:
* Names may start with a letter, a digit or an underscore. Leading digits or underscores will be stripped from the "id" attributes.
* Names must only contain letters, digits, underscores, hyphens and colons.
* Root forms may have an empty name.
Solves #1919 and #3021 on a wider scope.
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);
The problem was that "data_class" was used in two places: FormBuilder::build() and PropertyPathMapper.
PropertyPathMapper was already constructed during FormType::buildForm(), so any data class changes made to the FormBuilder wouldn't affect the data class of the PropertyPathMapper anymore and so lead to an inconsistent state.
