NAME

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

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.
