NAME

HTML::FormHandler::Field::Checkbox - a checkbox field type

VERSION

version 0.40068

DESCRIPTION

This field is very similar to the Boolean Widget except that this field allows other positive values besides 1. Since unselected checkboxes do not return a parameter, fields with Checkbox type will always be set to the 'input_without_param' default if they do not appear in the form.

checkbox

checkbox_value

In order to create the HTML for a checkbox, there must be a 'value="xx"'. This value is specified with the 'checkbox_value' attribute, which defaults to 1.

input_without_param

If the checkbox is not checked, it will be set to the value of this attribute (the unchecked value). Default = 0. Because unchecked checkboxes do not return anything in the HTTP parameters, the absence of a checkbox key in the parameters hash forces this field to this value. This means that Checkbox fields, unlike other fields, will not be ignored if there is no input. If a particular checkbox should not be processed for a particular form, you must set 'inactive' to 1 instead.

Note that a checkbox is only 'checked' when the 'checkbox_value' is provided. The 'value' for a non-checked checkbox is only really useful for creating form values such as are stored in a database.
