🏷️ NAME

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

🚀 Quick Reference

📝 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
    },
}
