Analysis of yii Implementation to Create Verification Code Instance

In this paper, the method of creating verification code by yii is described as an example. The specific steps are as follows:

1. Add the following code under SiteController action ():

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',
 ),
);

2. (1) Add code under LoginForm model rules ():

//captche class needed
array('verifyCode', 'captcha','allowEmpty'=>!CCaptcha::checkRequirements()),

(2) Add attributes under LoginForm model:

public $verifyCode;

3. Add code under ContactForm model rules ():

// verifyCode needs to be entered correctly
array('verifyCode', 'captcha', 'allowEmpty'=>!CCaptcha::checkRequirements()),

4. Add code under login view:

<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>

This example code is only a brief description of the main functions, and readers can further improve the program code according to their own project requirements, so that its functions are more practical.
