NAME

Data::FormValidator::Filters - Basic set of filters available in an Data::FormValidator profile.

SYNOPSIS

    use Data::FormValidator;

    my $validator = new Data::FormValidator( "/home/user/input_profiles.pl" );
    my $results = $validator->check(  \%fdat, "customer_infos" );

DESCRIPTION

These are the builtin filters which may be specified as a name in the filters and field_filters parameters of the input profile. You may also call these functions directly through the procedural interface by either importing them directly or importing the whole :filters group. For example, if you want to access the trim function directly, you could either do:

    use Data::FormValidator::Filters (qw/filter_trim/);
    or
    use Data::FormValidator::Filters (:filters);

    $string = filter_trim($string);

Notice that when you call filters directly, you'll need to prefix the filter name with "filter_".
