Here's my own implementation of a base form class:
<?php
/**
* Symfonians base non-Propel form class
*
*/
class BaseForm extends sfForm
{
const REQUIRED_CLASS_NAME = 'required';
/**
* Public constructor
*
* @see sfForm
*/
public function __construct($defaults = array(), $options = array(),
$CSRFSecret = null)
{
parent::__construct($defaults, $options, $CSRFSecret);
$this->postSetup();
}
/**
* Post setup final method, cannot be overriden
*
*/
final private function postSetup()
{
$this->handleRequiredFields();
}
/**
* Adds a CSS class name to required widgets
*
*/
protected function handleRequiredFields()
{
if (!$this->validatorSchema)
{
return;
}
foreach ($this->validatorSchema->getFields() as $fieldName => $validator)
{
/* @var $validator sfValidatorBase */
if (true === $validator->getOption('required'))
{
if (!array_key_exists($fieldName, $this->widgetSchema->getFields()))
{
continue;
}
/* @var $widget sfWidget */
$widget = $this->widgetSchema[$fieldName];
$class = trim($widget->getAttribute('class'));
if (!$class)
{
$class = self::REQUIRED_CLASS_NAME;
}
else if (!preg_match(sprintf('/%s/i',
self::REQUIRED_CLASS_NAME), $class))
{
$class = sprintf('%s%s', $class, self::REQUIRED_CLASS_NAME);
}
$widget->setAttribute('class', $class);
}
}
}
}
As you can see, all required widgets have a DOM class set
automatically when they are required by a validator. The main problem
is if the class attribute is added ok for a widget rendering, it's
quite difficult to add something for its label or the form row
container, because the renderRow() of the sfWidgetSchemaFormater class
has no reference to the validatorSchema... so a hackish way to achieve
such a detection would be to parse the rendered widget to see if it
contains the required DOM class, but it's way to hackish to exist in
symfony :-)
If anybody have a clever idea, it's more than welcome !
