yii注册

注册会使用验证码，下面是验证码的使用方法：

Yii中如何使用验证码：



在Model层的文件中插入



　　public $verifyCode;



　　在rules()中插入



　　array('verifyCode', 'captcha', 'allowEmpty'=>!CCaptcha::checkRequirements()),



       在attributeLabels()中插入



　　'verifyCode' =>'验证码';



在Controller层的文件中插入



      public function actions()

 {

  return array(

   // captcha action renders the CAPTCHA image displayed on the contact page

   'captcha'=>array(

    'class'=>'CCaptchaAction',

    'backColor'=>0xFFFFFF,



   ),



  );

 }



最后在View层的文件中插入



     <?php if(CCaptcha::checkRequirements()): ?>

        <div class="row">

                <?php echo $form->labelEx($model,'verifyCode'); ?>

            <div>

                <?php $this->widget('CCaptcha'); ?>

                <?php echo $form->textField($model,'verifyCode');?>

     </div>

  <div class="hint">请输入验证码中的图片

  <br/>不区分大小写

                </div>

  <?php echo $form->error($model,'verifyCode'); ?>

       </div>

       <?php endif;?>
