SYNOPSIS

$form->constraint({
type => 'CallbackOnce',
name => 'foo',

my ( $value, $params ) = @_;
# return true or false
}

DESCRIPTION

Unlinke the HTML::FormFu::Constraint::Callback, this callback is only called once, regardless of how many values are submitted.

The first argument passed to the callback is the submitted value for the associated field; this may be a single value or an arrayref of value. The second argument passed to the callback is a hashref of name/value pairs for all input fields.

This constraint doesn't honour the "not()" value.

METHODS

Arguments: \&sub_ref
