HTML::FormFu::Element::_Field(3)

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 its value set to its 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 its value set to its 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_single
If true, then the field's label should be rendered to the right of the field control. (When the field is used within a Multi block, the position of the label is controlled by the "reverse_multi" option instead.)

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).

Exception: If the label tag is 'legend', then the reverse_single attribute is ignored; the legend always appears as the first tag within the container tag.

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"

  repeatable_count
Only available for fields attached to a Repeatable element, after $repeatable->repeat($count) has been called.

The value is inherited from "repeatable_count" in HTML::FormFu::Element::Repeatable.
