<?php /** * 在php中验证复选框的有效性 * by www.jb200.com */ $value = 'yes'; echo "<input type='checkbox' name='subscribe' value='yes'/> 验证数据"; if (isset($_POST['subscribe'])) { if ($_POST['subscribe'] == $value) { $subscribed = true; } else { $subscribed = false; print '提交的复选框值无效。'; } } else { $subscribed = false; } if ($subscribed) { print '验证有效!'; } else { print '验证无效!'; }
