Email Verification in yii framework

Question

I want to verify the user when he click the random generated URL.

Give me solution for these two process.

1.What is the URL manager configuration rules for get the hash (string and numbers) from url request?

2.How can I compare the hash value in URL with my hash value in database on Controller/Action?

Code for sending email (it's working fine)

protected function afterSave()
 {
$activation_url = Yii::app()->createAbsoluteUrl('SignUp/Activate',array('activate_link'=>$this->activate_link));
Yii::import('ext.yii-mail.YiiMailMessage');
$message = new YiiMailMessage;
$message->setBody($activation_url);
$message->subject = 'Hello hell';
$message->addTo($this->email);
$message->from = Yii::app()->params['adminEmail'];
Yii::app()->mail->send($message);
return true;
 }

Code in Controller

public function actionActivate($activation) {
$model= Signup::model()->findByAttributes(array(
  'activate_link' => $activation
));
if ($model === null)
    $this->redirect('index.php');

else 
   $model->user_status = 1;
$model->save();
$this->redirect('index.php');
//redirect / flash / login whatever

}

and current URLManager configuration

'urlManager'=>array(
        'urlFormat'=>'path',
        'showScriptName'=>false,
        'rules'=>array(
            '<controller:\w+>/<id:\d+>' => '<controller>/view',
            '<controller:\w+>/<action:\w+>/<id:\d+>' => '<controller>/<action>',
            '<controller:\w+>/<action:\w+>' => '<controller>/<action>',

        ),
    ),

Answer 1

Make change in your Url manager as shown

'urlManager'=>array(
//HK_DEVELOPER NR:CHANGED TO GET TO GET THE URL IN DESIRED FORMAT
    'urlFormat'=>'get',
    'rules'=>array(
        '<controller:\w+>/<id:\d+>'=>'<controller>/view',
        '<controller:\w+>/<action:\w+>/<id:\d+>'=>'<controller>/<action>',
        '<controller:\w+>/<action:\w+>'=>'<controller>/<action>',
    ),
),

And the sample confirm action Send the email in the format of get parameters with the key in the url and get that key in action as i have done in passkey

public function actionConfirm(){
        //HK_DEVELOPER_NR:This action will confirm the user and change status from not authorize to authorized
        $passkey=$_GET['key'];
        $details=User::model()->findByAttributes(array('confirmationCode'=>$passkey));
        if(count($details)>=1)
        {
            if($details['userStatusId']==2){
                //CHECK IF AUTHORIZED REDIRECT TO PROFILE VIEW
                $url=Yii::app()->createUrl('site/login&joinbdp=false');
                $this->redirect($url);//USER CLICKS ON THE REGISTERATION LINK TWICE
            }else{
                $register=new Registerationconf;
                $value=$details['userId'];
                $register->userId=$value;
                $register->IPAddress=Yii::app()->request->userHostAddress;
                $register->confirmationTime=new CDbExpression('NOW()');
                $register->save();
                //CHANGE STATUS FROM NOT AUTHORIZED TO AUTHORIZED
                $post=User::model()->updateAll(array('userStatusId'=>'2'), 'confirmationCode=:confirmationCode',array(':confirmationCode'=>$passkey));
                $this->render('sucess');
            }
        }else {
            //IF USER IS REMOVED AND TRIES TO ACTIVATE THE LINK AGAIN
            echo "Please use valid URL. ";
        }
    }
