yii rules使用获取error信息

model中:
public function rules(){
return array(
array('Name,Email','required'),
array('Email','unique','message'=>'{value}出错啦'),{value}为添加的数据
);
}

controller中:
$model = new myModel();		//实例化相关表的模型类
$model->attributes = $_POST;	//对attributes赋值为提交上来（需要验证）的数据，字段为rules中safe
$model->validate();		//这里会自动调用验证规则rules
$model->getErrors();	//获取所有验证字段的错误信息array('FName'=>array(0 =>'Fname cannot be blank.' ),'字段'=>array(0=>'message'),...)
$model->getErrors('Email');		//获取当前传入字段的错误信息array(0 =>'Fname cannot be blank.' )
$model->getError('Email');		//'message信息'

//$form = new CActiveForm();[views中$form=$this->beginWidget('CActiveForm');]
//echo $form->errorSummary($model);打印出所有rules错误信息
