NAME

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

CONTENTS

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

<B>Note:B> 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 more 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
        },
    }
