=head1 NAME
HTML::FormHandler::Field::Checkbox - a checkbox field type
=head1 VERSION
version 0.40057
=head1 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.
=head2 widget
checkbox
=head2 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.
=head2 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.
