=head1 NAME
Validation::Class::Directive - Base Class for Validation Class Directives
=head1 VERSION
version 7.900056
=head1 SYNOPSIS
package Validation::Class::Directive::CheckBlacklist;
use base 'Validation::Class::Directive';
use strict;
use warnings;
use Validation::Class::Util;
use File::Slurp;
has 'mixin' => 0;
has 'field' => 1;
has 'multi' => 0;
has 'message' => '%s has been blacklisted';
sub validate {
my $self = shift;
my ($proto, $field, $param) = @_;
if (defined $field->{check_blacklist} && $param) {
# is the parameter value blacklisted?
my @blacklist = read_file('/blacklist.txt');
$self->error if grep { $param =~ /^$_$/ } @blacklist;
}
}
1;
... in your validation class:
package MyApp::Person;
use Validation::Class;
field ip_address => {
required => 1,
check_blacklist => 1
};
1;
... in your application:
package main;
use MyApp::Person;
my $person = MyApp::Person->new(ip_address => '0.0.0.0');
unless ($person->validates('ip_address')) {
# handle validation error
}
=head1 DESCRIPTION
You can extend Validation::Class by creating your own validation rules
(directives). Validation::Class::Directive provides a base-class for you to use
when creating new directive classes. Please see L<Validation::Class::Directives>
for a complete list of core directives.
