Yii register User with Email

Ill introduce how to make a simple email registration with Yii Forms and using an email extension for yii.
If you haven’t installed any email extensions check this post Yii email extension

Step 1 – Create the user table

CREATE TABLE JUser(

userid int(11) NOT NULL PRIMARY KEY AUTO_INCREMENT,

username varchar(40) NOT NULL,

email varchar(40) NOT NULL,

activation varchar(40) NOT NULL

)

Step 2 – Create the form using Gii

If you dont know what gii is check here Gii
To create the form you will need the user model which also can be created with gii, as long as you have the table in your database

After creating the form a register.php will be created under views
Put that register.php under site folder
Also a code will be shown when you create the form, thats the action for the form
Copy and paste that code in to your SiteController.php

Step 3 – Add a link to register.php

Find and change the part in main.php under views/layouts to look like this

...

<?php $this->widget('zii.widgets.CMenu',array(

'items'=>array(

array('label'=>'Home', 'url'=>array('/site/index')),

array('label'=>'About', 'url'=>array('/site/page', 'view'=>'about')),

array('label'=>'Contact', 'url'=>array('/site/contact')),

array('label'=>'Login', 'url'=>array('/site/login'), 'visible'=>Yii::app()->user->isGuest),

array('label'=>'Register', 'url'=>array('/site/register')),

array('label'=>'Logout ('.Yii::app()->user->name.')', 'url'=>array('/site/logout'), 'visible'=>!Yii::app()->user->isGuest)

)); ?>

</div>

...

Step 4 – Controller Register Action

For simplicity I’ll ask for a username and email to register, Adding other fields is pretty easy with Yii.

public function actionRegister()
	{
		$model = new JUser('register');

if(isset($_POST['JUser']))
		{
			$model->attributes = $_POST['JUser'];
			if($model->validate())
			{
				
				$activation = md5(uniqid(rand(), true));
				
				//Check to see if the email is already taken
				if( $model->findByAttributes( array('email'=>$model->email) )){
					$this->renderText('That email is already taken!',true);
				}else {
					// Send the email:
					$message_part1 = "Please click on this link to Activate your Account :nn";
					$message_part2 = "http://localhost/myapp/index.php?r=site/activate" . '?email=' . urlencode($model->email) . '&activation='. $activation;
					
					$yiimail = new YiiMailMessage;
					$yiimail->setBody($message_part1 . $message_part2,'text/html');
					$yiimail->subject = 'Service';
					$yiimail->addTo('myemail@email.com');
					$yiimail->from = 'myservice@email.com';
					Yii::app()->mail->send($yiimail);
					
					$model->activation = $activation;

$model->save();
					
					$this->renderText('Click on the Activation Link in your email to Activate your account',true);
				}
				
			}
		}
                //reset modell    
                $model = new JUser('activation');
		$this->render('register',array('model'=>$model));
	}

public function actionRegister()

{

$model = new JUser('register');

if(isset($_POST['JUser']))

{

$model->attributes = $_POST['JUser'];

if($model->validate())

{

$activation = md5(uniqid(rand(), true));

//Check to see if the email is already taken

if( $model->findByAttributes( array('email'=>$model->email) )){

$this->renderText('That email is already taken!',true);

}else {

// Send the email:

$message_part1 = "Please click on this link to Activate your Account :nn";

$message_part2 = "http://localhost/myapp/index.php?r=site/activate" . '?email=' . urlencode($model->email) . '&activation='. $activation;

$yiimail = new YiiMailMessage;

$yiimail->setBody($message_part1 . $message_part2,'text/html');

$yiimail->subject = 'Service';

$yiimail->addTo('myemail@email.com');

$yiimail->from = 'myservice@email.com';

Yii::app()->mail->send($yiimail);

$model->activation = $activation;

$model->save();

$this->renderText('Click on the Activation Link in your email to Activate your account',true);

}

//reset modell

$model = new JUser('activation');

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

}

Step 5 – Activation Page and Action

Notice that these fields are hidden and will get their values from the Url, on submit the activation action will be called

<?php $form=$this->beginWidget('CActiveForm', array(

'id'=>'juser-activate-form',

'enableAjaxValidation'=>false,

)); ?>

<p class="note">Press the button to activate your Account</p>

<?php echo $form->errorSummary($model); ?>

<?php echo $form->hiddenField($model,'activation',array('type'=>"hidden",'value'=>Yii::app()->getRequest()->getQuery('activation'))); ?>

<?php echo $form->hiddenField($model,'email',array('type'=>"hidden",'value'=>Yii::app()->getRequest()->getQuery('email'))); ?>

<?php echo CHtml::submitButton('Submit'); ?>

</div>

<?php $this->endWidget(); ?>

</div>

public function actionActivate()

{

$model = new JUser('activation');

if(isset($_POST['JUser']))

{

$model->attributes=$_POST['JUser'];

$model = $model->findByAttributes( array('email'=>$model->email,'activation'=>$model->activation) );

if( $model ){

$model->activation = null;

$model->save();

}

//reset modell

$model = new JUser('activation');

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

}
