/app/views/user/index.view
<?if ($this->controller->Session->read('login')!=1):?>
<?echo $html->formTag('/user/login');?>
<?echo $html->input('user/name');?><br>

</form>
<?else:?>
<?endif?>
简单的用户验证 试用$model->findByFields(); 可以用model表中任意字段查询
$model->set($data);
$model->set($key,$value);
可以将查询结果直接set 后 save 如果有 主键值 会update ，如果没有 会insert到表里面。
