Php 显示来自模型验证规则的消息

Php 显示来自模型验证规则的消息,php,yii,Php,Yii,我在访问由我的模型中的某个自定义规则生成的消息时遇到问题 在模型中: public function rules() { // NOTE: you should only define rules for those attributes that // will receive user inputs. return array( array('active_yn', 'numerical', 'integerOn

我在访问由我的模型中的某个自定义规则生成的消息时遇到问题

在模型中:

public function rules()
    {
        // NOTE: you should only define rules for those attributes that
        // will receive user inputs.
        return array(
            array('active_yn', 'numerical', 'integerOnly'=>true),
            array('user_name', 'length', 'max'=>20),
            array('password', 'length', 'max'=>100),
            array('full_name', 'length', 'max'=>150),
            // The following rule is used by search().
            // Please remove those attributes that should not be searched.
            array('user_id, user_name, full_name, active_yn', 'safe', 'on'=>'search'),
            array('user_name', 'unique', 'on'=>'api_save, insert', 'message'=>'User already in system'),
            array('user_name, full_name', 'required', 'on'=>'api_save', 'message'=>'Required field, {attribute}, is missing'),
        );
    }
在我的控制器里。这是一个REST接口

public function actioncreate(){
        $user = new User();
        $user->scenario = 'api_save';

        // Try to assign POST values to attributes
        if(isset($_POST)){
            foreach($_POST as $key=>$value) {
                // Does the model have this attribute? If not raise an error
                if($user->hasAttribute($key)){
                    $user->$key = $value;
                }else{
                    $var = array('status'=>500,'body'=>'Parameter <b>'.$key.'</b> is not allowed for model');
                    $send = new sendResponse($var);
                }
            }
        }else{
            $var = array('status'=>500,'body'=>'Parameters required for creation');
            $send = new sendResponse($var);
        }
        if(!$user->validate()){
            $str .= $user->message;
            $var = array('status'=>500,'body'=>$str);
            $send = new sendResponse($var);
        }
        $user->save();
        $var = array('status'=>200,'body'=>CJSON::encode($user));
        $send = new sendResponse($var);
    }
公共函数actioncreate(){
$user=新用户();
$user->scenario='api_save';
//尝试将POST值指定给属性
国际单项体育联合会(国际单项体育联合会){
foreach($\发布为$key=>$value){
//模型是否具有此属性?如果没有,则引发错误
如果($user->hasAttribute($key)){
$user->$key=$value;
}否则{
$var=array('status'=>500,'body'=>Parameter'.$key.'不允许用于模型');
$send=新发送响应($var);
}
}
}否则{
$var=array('status'=>500,'body'=>'Parameters required for creation');
$send=新发送响应($var);
}
如果(!$user->validate()){
$str.=$user->message;
$var=array('status'=>500,'body'=>$str);
$send=新发送响应($var);
}
$user->save();
$var=array('status'=>200,'body'=>CJSON::encode($user));
$send=新发送响应($var);
}
如果模型未验证,我希望显示来自模型的消息。我已经尝试了
getError
getErrors
,但是我收到一个错误,说“错误未定义”


感谢您对可能是一个简单问题的帮助

经过进一步搜索,我找到了答案:

   if($user->save() === false){
        $str = '';
        foreach ($user->errors as $value) {
            $str .= $value[0]."; ";
        }
        $var = array('status'=>500,'body'=>$str);
        $send = new sendResponse($var);
    }else{
        $var = array('status'=>200,'body'=>CJSON::encode($user));
        $send = new sendResponse($var);
    }
我跳过了验证步骤,只是保存了模型。如果它返回了
false
,那么我就能够将
$user->errors
作为数组或错误消息拉出来
