ContentModel.class.php页面：

<?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'), ); } ?>

UserModel.class.php页面：

1 2 3 4 5 6 7

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

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。
