DESCRIPTION
Creates a multi element containing 3 select menus for the day, month and year.

A date element named "foo" would result in 3 select menus with the names "foo_day", "foo_month" and "foo_year". The names can instead be overridden by the "name" value in "day", "month" and "year".

This element automatically merges the input parameters from the select menu into a single date parameter (and doesn't delete the individual menu's parameters).

METHODS

  default
Arguments: DateTime object

Arguments: $date_string

Accepts either a DateTime object, or a string containing a date, matching the "strftime" format. Overwrites any default value set in "day", "month" or "year".

  default_natural
Arguments: $date_string

    - type: Date
      default_natural: 'today'

Accepts a date/time string suitable for passing to "parse_datetime" in DateTime::Format::Natural.

  default_datetime_args
    - type: Date
      default_natural: 'today'
      default_datetime_args:
        set_time_zone: 'Europe/London'

Accepts a hashref of method-names / values that will be called on the "default" DateTime object, before the select fields' values are set from it.

  strftime
Default Value: "%d-%m-%Y"

The format of the date as returned by "params" in HTML::FormFu, if "auto_inflate" is not set.

If "auto_inflate" is used, this is still the format that the parameter will be in prior to the DateTime inflator being run; which is what any Filters and Constraints will receive.

  day
Arguments: \%setting

Set values effecting the "day" select menu. Known keys are:

name

Override the auto-generated name of the select menu.

default

Set the default value of the select menu

prefix

Arguments: $value

Arguments: \@values

A string or arrayref of strings to be inserted into the start of the select menu.

Each value is only used as the label for a select item - the value for each of these items is always the empty string ''.

prefix_loc

Arguments: $localization_key

Arguments: \@localization_keys

A localized string or arrayref of localized strings to be inserted into the start of the select menu.

Each value is localized and then only used as the label for a select item - the value for each of these items is always the empty string ''.

Use "prefix_loc" insted of "prefix".

  month
Arguments: \%setting

Set values effecting the "month" select menu. Known keys are:

name

Override the auto-generated name of the select menu.

default

Set the default value of the select menu

prefix

Arguments: $value

Arguments: \@values

A string or arrayref of strings to be inserted into the start of the select menu.

Each value is only used as the label for a select item - the value for each of these items is always the empty string ''.

prefix_loc

Arguments: $localization_key

Arguments: \@localization_keys

A localized string or arrayref of localized strings to be inserted into the start of the select menu.

Each value is localized and then only used as the label for a select item - the value for each of these items is always the empty string ''.

Use "prefix_loc" insted of "prefix".

names

Arguments: \@months

A list of month names used for the month menu.

If not set, the list of month names is obtained from DateTime::Locale using the locale set in "languages" in HTML::FormFu.

short_names

Argument: bool

If true (and "months" is not set) the list of abbreviated month names is obtained from DateTime::Locale using the locale set in "languages" in HTML::FormFu.

  year
Arguments: \%setting

Set values effecting the "year" select menu. Known keys are:

name

Override the auto-generated name of the select menu.

default

Set the default value of the select menu

prefix

Arguments: $value

Arguments: \@values

A string or arrayref of strings to be inserted into the start of the select menu.

Each value is only used as the label for a select item - the value for each of these items is always the empty string ''.

prefix_loc

Arguments: $localization_key

Arguments: \@localization_keys

A localized string or arrayref of localized strings to be inserted into the start of the select menu.

Each value is localized and then only used as the label for a select item - the value for each of these items is always the empty string ''.

Use "prefix_loc" insted of "prefix".

list

Arguments: \@years

A list of years used for the year menu.

If this is set, "reference", "less" and "plus" are ignored.

reference

Arguments: $year

Default Value: the current year, calculated from time()

If "list" is not set, the list is created from the range of "reference - year_less" to "reference + year_plus".

less

Arguments: $count

Default Value: 0

plus

Arguments: $count

Default Value: 10

reverse

Arguments: bool

Default Value: 0

If true, the list of years is listed in reverse (decreasing) order.

  field_order
Arguments: \@fields

Default Value: ['day', 'month', 'year']

Specify the order of the date fields in the rendered HTML.

Not all 3 fields are required. No single field can be used more than once.

  auto_inflate
If true, a DateTime Inflator will automatically be added to the element, and it will be given a formatter so that stringification will result in the format specified in "strftime".

If you require the DateTime Inflator to have a different stringification format to the format used internally by your Filters and Constraints, then you must explicitly add your own DateTime Inflator, rather than using "auto_inflate".

CAVEATS
Although this element inherits from HTML::FormFu::Element::Block, its behaviour for the methods filter/filters, constraint/constraints, inflator/inflators, validator/validators and transformer/transformers is more like that of a field element, meaning all processors are added directly to the date element, not to its select-menu child elements.

This element's get_elements and get_all_elements are inherited from HTML::FormFu::Element::Block, and so have the same behaviour. However, it overrides the "get_fields|HTML::FormFu/get_fields" method, such that it returns both itself and its child elements.
