NAME

HTML::FormFu::Element::_Field - base class for all form-field elements

DESCRIPTION

Base-class for all form-field elements.

METHODS

default

Set the form-field's default value.

default_xml

Arguments: $string

If you don't want the default value to be XML-escaped, use the "default_xml" method instead of </default>.

default_loc

Arguments: $localization_key

Set the default value using a L10N key.

value

For most fields, "value" is an alias for "default".

For the HTML::FormFu::Element::Checkbox and HTML::FormFu::Element::Radio elements, "value" sets what the value of the field will be if it is checked or selected. If the "default" is the same as the "value", then the field will be checked or selected when rendered.

For the HTML::FormFu::Element::Radiogroup and HTML::FormFu::Element::Select elements, the "value" is ignored: /values or /options provides the equivalent function.

value_xml

Arguments: $string

If you don't want the value to be XML-escaped, use the "value_xml" method instead of </value>.

value_loc

Arguments: $localization_key

Set the value using a L10N key.

non_param

Arguments: bool

If true, values for this field are never returned by "params" in HTML::FormFu, "param" in HTML::FormFu and "valid" in HTML::FormFu.

This is useful for Submit buttons, when you only use its value as an indicator.

Default Value: false

label

Set a label to communicate the purpose of the form-field to the user.

label_xml

Arguments: $string

If you don't want the label to be XML-escaped, use the "label_xml" method instead of </label>.

label_loc

Arguments: $localization_key

Set the label using a L10N key.

comment

Set a comment to be displayed along with the form-field.

comment_xml

Arguments: $string

If you don't want the comment to be XML-escaped, use the "comment_xml" method instead of </comment>.

comment_loc

Arguments: $localization_key

Set the comment using a L10N key.

container_tag

Set which tag-name should be used to contain the various field parts (field, label, comment, errors, etc.).

Default Value: 'div'

javascript

Arguments: [$javascript]

If set, the contents will be rendered within a script tag, within the field's container.

retain_default

If "retain_default" is true and the form was submitted, but the field didn't have a value submitted, then when the form is redisplayed to the user the field will have it's value set to it's default value , rather than the usual behaviour of having an empty value.

Default Value: false

force_default

If "force_default" is true and the form was submitted, and the field has a default/value set, then when the form is redisplayed to the user the field will have it's value set to it's default value.

If the default value is being changed after FormFu->process is being called the later default value is respected for rendering, *but* nevertheless the input value doesn't respect that, it will remain the first value.

Default Value: false

default_empty_value

Designed for use by Checkbox fields. Normally if a checkbox is not checked, no value is submitted for that field. If default_empty_value is true, the Checkbox field is given an empty value during "process". Please note that, with this setting, the checkbox gets an EMPTY value (as opposed to no value at all without enabling it), NOT the default value assigned to the element (if any).

Default Value: false

reverse_multi

If true, then when the field is used within a Multi block, the field's label should be rendered to the right of the field control

The default value is false, causing the label to be rendered to the left of the field control (or to be explicit: the markup for the label comes before the field control in the source).

Default Value: false
