automatically add a class to the fields in a form that are required

[nicolaas]

most of the time, when you have fields in a form, you want to highlight which ones are required. Would it be possible to add a class to the holder of each required field?

I tried to do this:

foreach($requiredFieldsArr as $fieldName) {

$newField = $fields->dataFieldByName($fieldName); $newField->setRightTitle("*"); $fields->replaceField($fieldName, $newField);

}

dataFieldByName as well as fieldByName do not actually return the right fields as stated in the documentation.

Note, that the above method shown is pretty clumsy. It would be much better to have a class than an asterix with setRightTitle

You can do this, though (not sure if that's what you mean):

function Form() {
	$reqFields = array(
		'a',
		'b'
	);
	$form = new Form($this, 'Form',
		new FieldSet(
			new TextField('a'),
			new TextField('b')
		),
		new FieldSet(
			new FormAction('submit', 'Submit')
		),
		new RequiredFields($reqFields)
	);
	foreach($reqFields as $field => $value) {
		$fieldObj = $form->dataFieldByName($value);
		$fieldObj->addExtraClass('required');
	}
	return $form;
}

Hmmm, this does not seem to work ( I am trying to add it to the ecommerce application), but the principles is sound - great
