Rose::HTML::Form::Field::DateTime - Text field that inflates valid dates and times into DateTime objects.
$field = Rose::HTML::Form::Field::DateTime->new( label => 'Date', name => 'date', default => '12/31/2002 8pm'); print $field->internal_value; # "2002-12-31T20:00:00" print $field->output_value; # "2002-12-31 08:00:00 PM" $field->input_value('blah'); # "Could not parse date: blah" $field->validate or warn $field->error; $field->input_value('4/30/1980 5:30 p.m.'); $dt = $field->internal_value; # DateTime object print $dt->hour; # 17 print $dt->day_name; # Wednesday print $field->html; ...
Rose::HTML::Form::Field::DateTime is a subclass of Rose::HTML::Form::Field::Text that allows only valid dates as input, which it then coerces to DateTime objects. It overrides the validate(), inflate_value(), and deflate_value() methods of its parent class.
Valid input is converted to the format "YYYY-MM-DD HH:MM:SS AM/PM" on output.
Get or set the date parser object. This object must include a parse_datetime() method that takes a single string as an argument and returns a DateTime object, or undef if parsing fails.
parse_datetime()
If the parser object has an error() method, it will be called to set the error message after a failed parsing attempt.
error()
The parser object defaults to Rose::DateTime::Parser->new().
Get or set the format string passed to Rose::DateTime::Util's format_date function in order to generate the field's output value. Defaults to "%Y-%m-%d %I:%M:%S %p"
If the parser object has a time_zone() method, this method simply calls it, passing all arguments. Otherwise, undef is returned.
Other examples of custom fields:
A text field that only accepts valid email addresses.
Uses inflate/deflate to coerce input into a fixed format.
A compound field whose internal value consists of more than one object.
A simple compound field that coalesces multiple subfields into a single value.
A compound field that uses inflate/deflate convert input from multiple subfields into a DateTime object.
A compound field that includes other compound fields and uses inflate/deflate convert input from multiple subfields into a DateTime object.
