本文以实例形式讲述了yii创建验证码的方法,具体步骤如下所示:

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 class="row">
<&#63;php
echo $form->labelEx($model,'verifyCode');
&#63;>
<&#63;php
$this->widget('CCaptcha');
&#63;>
<&#63;php
echo $form->textField($model,'verifyCode');
&#63;>
<&#63;php
echo $form->error($model,'verifyCode');
&#63;>
</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。
