DESCRIPTION

"filters()" and "filter" can be called on any form, block element (includes fieldsets) or field element.

If called on a field element, no "name" argument should be passed.

If called on a form or block element, if no "name" argument is provided, a new filter is created for and added to every field on that form or block.

See ``FORM LOGIC AND VALIDATION'' in HTML::FormFu for further details.

get_parent

Arguments: \%options
