FormMagick::Validator - validate data from FormMagick forms

SYNOPSIS

use FormMagick::Validator;

DESCRIPTION

This module provides some common validation routines. Validation routines return the string "OK" if they succeed, or a descriptive message if they fail.

Validation routines provided:

nonblank

The data is not an empty string : $data ne ""

number

The data is a number (strictly speaking, data is a positive number): $data =~ /^[0-9.]+$/

word

The data looks like a single word: $data !~ /\W/

minlength(n)

The data is at least n characters long: length($data) >= $n

maxlength(n)

The data is no more than n characters long: length($data) <= $n

exactlength(n)

The data is exactly n characters long: length($data) E== $n

lengthrange(n,m)

The data is between n and c<m> characters long: length($data) >= $n and length($data) <= $m.

url

The data looks like a (normalish) URL: $data =~ m!(http|ftp)://[\w/.-/)!

email

The data looks more or less like an internet email address: $data =~ /\@/

Note: not fully compliant with the entire gamut of RFC 822 addressing ;)

domain_name

The data looks like an internet domain name or hostname.

ip_number

The data looks like a valid IP number.

username

The data looks like a good, valid username

password

The data looks like a good password

date

The data looks like a date.

iso_country_code

The data is a standard 2-letter ISO country code. Uses Locale::Country to check.

US_state

The data is a standard 2-letter US state abbreviation. Uses Geography::State in non-strict mode.

US_zipcode

The data looks like a valid US zipcode

credit_card_type

The data looks like a valid type of credit card (eg Visa, Mastercard). Uses Business::CreditCard.

credit_card_number

The data looks like a valid credit card number Uses Business::CreditCard.

credit_card_expiry

The data looks like a valid credit card expiry date Uses Business::CreditCard.

These validation routines may be overridden and others may be added on a per-application basis. To do this, simply define a subroutine in your CGI script that works in a similar way and use its name in the VALIDATION attribute in your XML.
