问题描述
我是yii框架的新手，目前正在尝试通过数据库身份验证来建立登录名.但我反复收到此错误
Hi i'm quite new to yii framework, currently trying to establish a login through database authentication. but im repeatedly getting this error
CActiveForm及其行为没有名为方法或闭包 "getErrors".
CActiveForm and its behaviors do not have a method or closure named "getErrors".
有人可以帮我吗
在此处控制
<?php
class SiteController extends Controller
{
public function actions()
{
return array(
'captcha'=>array(
'class'=>'CCaptchaAction',
'backColor'=>0xFFFFFF,
),
'page'=>array(
'class'=>'CViewAction',
),
);
}
public function actionIndex()
{
$this->render('index');
}
public function actionError()
{
if($error=Yii::app()->errorHandler->error)
{
if(Yii::app()->request->isAjaxRequest)
echo $error['message'];
else
$this->render('error', $error);
}
}
public function actionContact()
{
$model=new ContactForm;
if(isset($_POST['ContactForm']))
{
$model->attributes=$_POST['ContactForm'];
if($model->validate())
{
$name='=?UTF-8?B?'.base64_encode($model->name).'?=';
$subject='=?UTF-8?B?'.base64_encode($model->subject).'?=';
$headers="From: $name <{$model->email}>\r\n".
"Reply-To: {$model->email}\r\n".
"MIME-Version: 1.0\r\n".
"Content-Type: text/plain; charset=UTF-8";
mail(Yii::app()->params['adminEmail'],$subject,$model->body,$headers);
Yii::app()->user->setFlash('contact','Thank you for contacting us. We will respond to you as soon as possible.');
$this->refresh();
}
}
$this->render('contact',array('model'=>$model));
}
public function actionLogin()
{
$form=new LoginForm;
if(isset($_POST['LoginForm']))
{
$form->attributes=$_POST['LoginForm'];
if($form->validate() && $form->login()) $this->redirect(Yii::app()->user->returnUrl);
}
$this->render('login',array('form'=>$form));
}
public function actionLogout()
{
Yii::app()->user->logout();
$this->redirect(Yii::app()->homeUrl);
}
}
继承模型
<?php
class LoginForm extends CFormModel
{
public $email;
public $password;
private $_identity;
public function rules()
{
return array(
array('email, password', 'required'),
array('email', 'email'),
array('password', 'authenticate'),
);
}
public function attributeLabels()
{
return array('email'=>'Email Address');
}
public function authenticate($attribute,$params)
{
if(!$this->hasErrors()) // we only want to authenticate when no input errors
{
$identity=new UserIdentity($this->email,$this->password);
$identity->authenticate();
switch($identity->errorCode)
{
case UserIdentity::ERROR_NONE:
Yii::app()->user->login($identity);
break;
case UserIdentity::ERROR_USERNAME_INVALID:
$this->addError('email','Email address is incorrect.');
break;
default: // UserIdentity::ERROR_PASSWORD_INVALID
$this->addError('password','Password is incorrect.');
break;
}
}
}
public function login()
{
if($this->_identity===null)
{
$this->_identity=new UserIdentity($this->username,$this->password);
$this->_identity->authenticate();
}
if($this->_identity->errorCode===UserIdentity::ERROR_NONE)
{
$duration=$this->rememberMe ? 3600*24*30 : 0; // 30 days
Yii::app()->user->login($this->_identity,$duration);
return true;
}
else
return false;
}
}
在这里查看
<?php
/* @var $this SiteController */
/* @var $model LoginForm */
/* @var $form CActiveForm */
$this->pageTitle=Yii::app()->name . ' - Login';
$this->breadcrumbs=array(
'Login',
);
?>
<h1>Login</h1>
<p>Please fill out the following form with your login credentials:</p>
<div class="form">
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'login-form',
'enableClientValidation'=>true,
'clientOptions'=>array(
'validateOnSubmit'=>true,
),
)); ?>
<p class="note">Fields with <span class="required">*</span> are required.</p>
<div>
<?php echo CHtml::beginForm(); ?>
<?php echo CHtml::errorSummary($form); ?>
<div>
<?php echo CHtml::activeLabel($form,'email'); ?>
<?php echo CHtml::activeTextField($form,'email') ?>
</div>
<div>
<?php echo CHtml::activeLabel($form,'password'); ?>
<?php echo CHtml::activePasswordField($form,'password') ?>
</div>
<div>
<?php echo CHtml::submitButton('Login'); ?>
</div>
<?php echo CHtml::endForm(); ?>
endWidget(); ?>
endWidget(); ?>
推荐答案
如果您包含更多错误，例如-它发生在哪一行以及在哪个文件中，或者最好是整个跟踪.从我在您的代码中阅读的内容来看，您似乎覆盖了$ form变量，该变量实际上保存了您的模型.在SiteController中，使用LoginForm模型初始化变量$form.然后，在视图中您会打错电话:
it would be good if you include more of the error - e.g. on which line it occured and in which file, or at best the whole trace..From what I read in your code it seems that you overwrite the $form variable, which actually hold your model.In the SiteController you initialize the variable $form with the LoginForm model.Then in the view you make this wrong call:
<?php $form=$this->beginWidget('CActiveForm', array(
'id'=>'login-form',
'enableClientValidation'=>true,
'clientOptions'=>array(
'validateOnSubmit'=>true,
),
));
?>
因此，在所有的CHtml调用中，您都将小部件而不是模型变量放到了函数中
Therefore in all the CHtml calls you put a widget instead of a model variable to the functions
由于您没有以特定方式使用窗口小部件的输出，因此删除$form = $this->widget...并将其仅保留为$this->widget..或将变量替换为新变量就足够了.
As you do not use the output of the widget in no specific way, it would be enough to remove the $form = $this->widget... and leave it only as $this->widget.. Or replace the variable for a new one.
<?php $myWidget = $this->beginWidget('CActiveForm', array(
'id'=>'login-form',
'enableClientValidation'=>true,
'clientOptions'=>array(
'validateOnSubmit'=>true,
),
));
?>
