一、ECshop中验证码的调用
<input type="text" size="8" name="captcha"class="inputBg" />
<img src="captcha.php?{$rand}" alt="captcha"onClick="this.src='captcha.php?'+Math.random()"class="captcha">
二、验证码的验证
if(empty($_POST['captcha']))
{
show_message($_LANG['order']['captcha_empty']);
}
include_once('includes/cls_captcha.php');
$validator = new captcha();
//$validator->session_word = 'captcha_login';
if(!$validator->check_word(($_POST['captcha'])))
{
show_message($_LANG['invalid_captcha']);
}
$GLOBALS['smarty']->assign('rand', mt_rand());
<pre name="code" class="php">// 验证码防止灌水刷屏
if((intval($_CFG['captcha']) & CAPTCHA_MESSAGE)&& gd_version() >0)
{
include_once('includes/cls_captcha.php');
$validator = new captcha();
//验证验证码是否正确
if(!$validator->check_word($_POST['captcha']))
{
show_message($_LANG['invalid_captcha']);
}
}
else
{
//没有验证码时,用时间来限制机器人发帖或恶意发评论
if (!isset($_SESSION['send_time']))
{
$_SESSION['send_time'] = 0;
}
$cur_time = gmtime();
if (($cur_time - $_SESSION['send_time']) < 30) //小于30秒禁止发评论
{
show_message($_LANG['cmt_spam_warning']);
}
}
四、由于版本问题出现错误的解决方法(Strict Standards: Redefining already defined constructor for class captcha……)
