一、在SiteController action()下添加如下代码：
return array( // captcha action renders the CAPTCHA image displayed on the contact page 'captcha'=>array( 'class'=>'CCaptchaAction', 'backColor'=>0xFFFFFF, ), // page action renders "static" pages stored under 'protected/views/site/pages' // They can be accessed via: index.php?r=site/page&view=FileName 'page'=>array( 'class'=>'CViewAction', ), );
二、(1)在LoginForm model rules()下添加代码：
//captche class needed array('verifyCode', 'captcha','allowEmpty'=>!CCaptcha::checkRequirements()),
(2)LoginForm model下添加属性：
public $verifyCode;
三、在ContactForm model rules()下添加代码：
// verifyCode needs to be entered correctly array('verifyCode', 'captcha', 'allowEmpty'=>!CCaptcha::checkRequirements()),
四、在login view下添加代码：
<div> <?php echo $form->labelEx($model,'verifyCode'); ?> <?php $this->widget('CCaptcha'); ?> <?php echo $form->textField($model,'verifyCode'); ?> <?php echo $form->error($model,'verifyCode'); ?> </div>
本例代码仅为主要功能简述，读者还可以根据自身项目需求进一步完善该程序代码，使其功能更具实用性。
