<?php
/**
 * Elgg checkbox input
 * Displays a checkbox input field
 *
 * @note This also includes a hidden input with the same name as the checkboxes
 * to make sure something is sent to the server.  The default value is 0.
 * If using JS, be specific to avoid selecting the hidden default value:
 * 	$('input[type=checkbox][name=name]')
 * 
 * @warning Passing integers as labels does not currently work due to a
 * deprecated hack that will be removed in Elgg 1.9. To use integer labels,
 * the labels must be character codes: 1 would be &#0049;
 *
 * @package Elgg
 * @subpackage Core
 *
 * @uses string $vars['name']     The name of the input fields
 *                                (Forced to an array by appending [])
 * @uses array  $vars['options']  An array of strings representing the
 *                                label => option for the each checkbox field
 * @uses string $vars['default']  The default value to send if nothing is checked.
 *                                Optional, defaults to 0. Set to FALSE for no default.
 * @uses bool   $vars['disabled'] Make all input elements disabled. Optional.
 * @uses string $vars['value']    The current value. Single value or array. Optional.
 * @uses string $vars['class']    Additional class of the list. Optional.
 * @uses string $vars['align']    'horizontal' or 'vertical' Default: 'vertical'
