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">
<?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。
