Simple checkboxes, one with a default value and the other without. Clonefish also takes care of the unique behaviour of the checkboxes: they're not present in the GET/POST arrays when the form is submitted and the checkbox was not checked. In clonefish, you may set up an "off value" for the checkbox inputs: the form element will contain this value when the checkbox was unchecked. It's never been easier creating a database insert of your form! Compare the values of the $_POST array and the results of a $clonefish->getElementValues() call below the form!
Below are the dumps of some PHP variables - submit the form to see the changes!
Contents of the $_POST array:
$_POST = array (
)
Results of a $clonefish->getElementValues() call: array ( 'newsletter' => 0, 'marketing' => 'Y', 'id' => 'inputcheckbox', )
