CActiveForm实际上是对Chtml类的封装，它与Chmtl不同的地方是CActiveForm提供了验证机制，

有三种：服务器端/客户端/ajax验证

表单：

<?php $form=$this->beginWidget('CActiveForm',    array(        'id'=>'contact_form',        'enableAjaxValidation'=>true//是否是ajax验证 //'enableClientValidation'=>true,//是否客户端验证         //'action'=>'site/contact',        //'method'=>'get',    )); ?><p class="note">Fields with <span class="required">*</span> are required.</p><div class="row">    <?php echo $form->labelEx($model,'name');  ?>    <?php echo $form->textField($model,'name');?>    <?php    //单独显示错误信息    echo $form->error($model,'name');    ?></div><div class="row">    <?php echo $form->labelEx($model,'email'); ?>    <?php echo $form->textField($model,'email'); ?>    <?php    //单独显示错误信息    echo $form->error($model,'email');    ?></div><div class="row">    <?php echo $form->labelEx($model,'subject'); ?>    <?php echo $form->textField($model,'subject',array('size'=>60,'maxlength'=>128)); ?></div><div class="row">    <?php echo $form->labelEx($model,'body'); ?>    <?php echo $form->textArea($model,'body',array('rows'=>6, 'cols'=>50)); ?></div><?php$model -> name = 0;echo $form->radioButtonList($model,'name',    array('1'=>'Male','0'=>'Female'),    array('separator'=>'&nbsp;','labelOptions'=>array('class'=>'')))?><div class="row">    <?php echo $form->labelEx($model,'label:'); ?>    <?php    $model ->name = array(1,2,3,4);//设定checkbox的默认值，其实应该在controller里面设定最好,radio,select的设定方法和这个一样    echo $form->checkBoxList($model,'name',        array('1'=>'Football','2'=>'Music','3'=>'Game','4'=>'basketball'),        array('separator'=>'&nbsp;','labelOptions'=>array('class'=>'mylabel'))    )    ?></div><?php if(extension_loaded('gd')): ?>    <div class="row">        <?php echo $form->labelEx($model,'verifyCode'); ?>        <div>            <?php $this->widget('CCaptcha'); ?>            <?php echo $form->textField($model,'verifyCode'); ?>        </div>        <div class="hint">Please enter the letters as they are shown in the image above.            <br/>Letters are not case-sensitive.</div>    </div><?php endif; ?><div class="row submit">    <?php    echo CHtml::submitButton('Submit');    ?></div>//总体显示错误信息<?php echo $form->errorSummary($model); ?><?php $this->endWidget(); ?>

验证：

public function actionContact(){    $model=new ContactForm;    //ajax validation    if(isset($_POST['ajax']) && $_POST['ajax']==='contact_form')    {        echo CActiveForm::validate($model);        Yii::app()->end();    }    if(isset($_POST['ContactForm']))    {        $model->attributes=$_POST['ContactForm'];        if($model->validate())//服务器端验证        {            $headers="From: {$model->email}\r\nReply-To: {$model->email}";            mail(Yii::app()->params['adminEmail'],$model->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));}
