Data::FormValidator::Constraints::Dates.3pm

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
                 },
         }
