HTML::FormFu::Element::_Group.3pm

NAME

HTML::FormFu::Element::_Group - grouped form field base-class

DESCRIPTION

Base class for HTML::FormFu::Element::Radiogroup and HTML::FormFu::Element::Select fields.

METHODS

options

Arguments: none

Arguments: \@options

     ---
     elements:
       - type: Select
         name: foo
         options:
           - [ 01, January ]
           - [ 02, February ]
           - value: 03
             label: March
             attributes:
               style: highlighted
           - [ 04, April ]
 
 

If passed no arguments, it returns an arrayref of the currently set options.

Use to set the list of items in the select menu / radiogroup.

It's arguments must be an array-ref of items. Each item may be an array ref of the form "[ $value, $label ]" or a hash-ref of the form "{ value => $value, label => $label }". Each hash-ref may also have the keys "attributes" and "label_attributes".

Passing an item containing a "group" key will, for Select fields, create an optgroup. And for RadioGroup fields, create a sub-group of radiobuttons with a new "span" block, with the classname "subgroup".

An example of Select optgroups:

     ---
     elements:
       - type: Select
         name: foo
         options:
           - label: "group 1"
             group:
               - [1a, 'item 1a']
               - [1b, 'item 1b']
           - label: "group 2"
             group:
               - [2a, 'item 2a']
               - [2b, 'item 2b']
 
 

When using the hash-ref construct, the "label_xml" and "label_loc" variants of "label" are supported, as are the "value_xml" and "value_loc" variants of "value", the "attributes_xml" variant of "attributes" and the "label_attributes_xml" variant of "label_attributes".

values

Arguments: \@values

     ---
     elements:
       - type: Radiogroup
         name: foo
         values:
           - jan
           - feb
           - mar
           - apr
 
 

A more concise alternative to ``options''. Use to set the list of values in the select menu / radiogroup.

It's arguments must be an array-ref of values. The labels used are the result of "ucfirst($value)".

value_range

Arguments: \@values

     ---
     elements:
       - type: Select
         name: foo
         value_range:
           - ""
           - 1
           - 12
 
 

Similar to ``values'', but the last 2 values are expanded to a range. Any preceeding values are used literally, allowing the common empty first item in select menus.

empty_first

If true, then a blank option will be inserted at the start of the option list (regardless of whether ``options'', ``values'' or ``value_range'' was used to populate the options). See also ``empty_first_label''.

empty_first_label

empty_first_label_xml

empty_first_label_loc

If ``empty_first'' is true, and "empty_first_label" is set, this value will be used as the label for the first option - so only the first option's value will be empty.

Is a sub-class of, and inherits methods from HTML::FormFu::Element::_Field, HTML::FormFu::Element
