=head1 NAME
HTML::FormHandler::Field::Date - a date field with formats
=head1 VERSION
version 0.40057
=head1 SUMMARY
This field may be used with the jQuery Datepicker plugin.
You can specify the format for the date using jQuery formatDate strings
or DateTime strftime formats. (Default format is format => '%Y-%m-%d'.)
d - "%e" - day of month (no leading zero)
dd - "%d" - day of month (two digit)
o - "%{day_of_year}" - day of the year (no leading zeros)
oo - "%j" - day of the year (three digit)
D - "%a" - day name short
DD - "%A" - day name long
m - "%{day_of_month}" - month of year (no leading zero)
mm - "%m" - month of year (two digit) "%m"
M - "%b" - month name short
MM - "%B" - month name long
y - "%y" - year (two digit)
yy - "%Y" - year (four digit)
@ - "%s" - Unix timestamp (ms since 01/01/1970)
For example:
has_field 'start_date' => ( type => 'Date', format => "dd/mm/y" );
or
has_field 'start_date' => ( type => 'Date', format => "%d/%m/%y" );
You can also set 'date_end' and 'date_start' attributes for validation
of the date range. Use iso_8601 formats for these dates ("yyyy-mm-dd");
has_field 'start_date' => ( type => 'Date', date_start => "2009-12-25" );
Customize error messages 'date_early' and 'date_late':
has_field 'start_date' => ( type => 'Date,
messages => { date_early => 'Pick a later date',
date_late => 'Pick an earlier date', } );
If form has 'is_html5' flag active it will render <input type="date" ... />
instead of type="text"
