ContentModel.class.php页面：

<&＃63;php
class ContentModel extends Model{
/*
* 自动验证
* array(验证字段，验证规则，错误提示，验证条件，附加规则，验证时间)
*/ 
protected $_validate = array(
array('title','require','标题必须填写!'),
array('content','require','内容必须填写!'), 
);
/* 
* 自动填充
* array(填充字段，填充内容，填充条件，附加规则)
*/
protected $_auto = array(
array('addtime','time',1,'function'),
);
}
&＃63;>

UserModel.class.php页面：

<&＃63;php
class UserModel extends Model{
protected $_validate = array(
array('username','','帐号名称已经存在！',0,'unique',1), 
);  
}
&＃63;>

这里需要注意的是，使用自动验证的时候 实例化时要用 $user = D("user") 而不能用 $user = M("user"),用M这种方法会报错，D函数用于实例化Model,M函数用户实例化一个没有模型的文件。
