NAME ^

Rose::HTML::Form::Field::DateTime - Text field that inflates valid dates and times into DateTime objects.

SYNOPSIS ^

    $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->day_name; # Wednesday

    print $field->html;
    ...

DESCRIPTION ^

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.

OBJECT METHODS ^

date_parser [PARSER]

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.

If the parser object has an error() method, it will be called to set the error message after a failed parsing attempt.

The parser object defaults to Rose::DateTime::Parser->new().

output_format [FORMAT]

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"

time_zone [TZ]

If the parser object has a time_zone() method, this method simply calls it, passing all arguments. Otherwise, undef is returned.

SEE ALSO ^
