Example form is linked to a database table, but won't be saved in this example.

When you submit the form, the value is presented with debug_dump(), so strings are quoted and array values listed.

:
: - Stop the submitted form from bring processed
: - Don't process the form, redirect to another page (e.g. login after session timeout), and remember the values for when they return.

<?php
	$field = new form_field_checkbox($form, 'Check');
	$field->db_field_set('check');
	$field->text_values_set('true', 'false'); // Remove to return a boolean.
?>
