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 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
         },
     }
