my ($check, $result, @args) = @{$validation->error('foo')};has_data
my $bool = $validation->has_data;Check if "input" is available for validation.
has_error
my $bool = $validation->has_error;
my $bool = $validation->has_error('foo');Check if validation resulted in errors, defaults to checking all fields.
is_valid
my $bool = $validation->is_valid;
my $bool = $validation->is_valid('foo');Check if validation was successful and field has a value, defaults to checking the current "topic".
optional
$validation = $validation->optional('foo');Change validation "topic".
param
my @names = $c->param;
my $foo = $c->param('foo');
my @foo = $c->param('foo');
