NAME

Data::FormValidator::Constraints::Dates - Validate Dates and Times

SYNOPSIS

use Data::FormValidator::Constraints::Dates qw(date_and_time);

# In a DFV profile...
constraint_methods => {
	# 'pp' denotes AM|PM for 12 hour representation
	my_time_field => date_and_time('MM/DD/YYYY hh:mm:ss pp'), 
}

DESCRIPTION

date_and_time

Note: This is a new module is a new addition to Data::FormValidator and is should be considered "Beta".

This constraint creates a regular expression based on the format string passed in to validate your date against. It understands the following symbols:

Y	year  (numeric)
M	month (numeric)
D 	day	  (numeric)
h	hour
m   minute
s	second
p	AM|PM

Other parts of the string become part of the regular expression, so you can do perlish things like this to create mor complex expressions:

'MM?/DD?/YYYY|YYYY-MM?-DD?'

Internally Date::Calc is used to test the functions.

BACKWARDS COMPATIBILITY

This older, more awkward interface is supported:

# In a Data::FormValidator Profile:
validator_packages => [qw(Data::FormValidator::Constraints::Dates)],
constraints => {
	date_and_time_field 	  => {
		constraint_method => 'date_and_time',
		params=>[\'MM/DD/YYYY hh:mm:ss pp'], # 'pp' denotes AM|PM for 12 hour representation
	},
}
