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;?>

C：TestController.php/actionReg方法

	public function actionReg()
	{
		$model=new TestReg('reg');
		if(isset($_POST['TestReg'])) {
		$aa=$model->attributes = $_POST['TestReg'];
		$model->validate();

		//$model->getErrors();
			if($model->save()) {
			$this->redirect(array('test/login'));
			}else{echo '333';}
		}

		
		$this->render('reg',array('model'=>$model));
	}

M：TestReg.php模型
