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
                },
        }
