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
},
}
