Yii dataProvider theme main.php

In my SiteController.php

public function actionIndex()
{
    // renders the view file 'protected/views/site/index.php'
    // using the default layout 'protected/views/layouts/main.php'
    //$this->render('index');

    $dataProviderUser=new CActiveDataProvider('User',array(
                'pagination'=>array(
                    'pageSize'=>20,
                ),
            ));
    $dataProviderDomain = new CActiveDataProvider('Domain');

    $this->render('index',array(
    'dataProvider1'=>$dataProviderUser,
    'dataProvider2'=>$dataProviderDomain
    ));
}

In my themes/k/views/layout/main.php

        <?php 
        if(!Yii::app()->user->isGuest)
        {
        $this->widget('zii.widgets.CListView', array(
            'dataProvider'=>$dataProvider2,
            'itemView'=>'_view',));
        ?>

This error appears: Undefined variable: dataProvider2

If i do this in my main.php:

<?php 
        $dataProvider2 = new CActiveDataProvider('Domain');
        if(!Yii::app()->user->isGuest)
        {
        $this->widget('zii.widgets.CListView', array(
            'dataProvider'=>$dataProvider2,
            'itemView'=>'_view',));
        ?>

That works fine so far. But if I go to the User Profil:

/user/view/id/5

Property "Domain.username" is not defined.

So in my User _view.php Yii seems to take the Domain Dataprovider.

How do I past those dataProviders to my layout main.php file? The SiteController.php doesn't seem to do that right.

Would be very nice, if someone has an idea here. Thanks in advanced.

Variables that you have defined in your controller action are only available to immediate view files that are being used to render a view. They are not available to layouts. However, layouts will be able to use public methods and properties of the controller. So, if you want to pass a variable to your layout you need to declare it as a property of the controller. There are two ways of doing this.

Firstly, you can just create a public variable.

Class YourController extends CController{

public $dataProvider2;

public function actionIndex(){
// renders the view file 'protected/views/site/index.php'
    // using the default layout 'protected/views/layouts/main.php'
    //$this->render('index');

    $dataProviderUser=new CActiveDataProvider('User',array(
                'pagination'=>array(
                    'pageSize'=>20,
                ),
            ));
    $dataProviderDomain = new CActiveDataProvider('Domain');

//Added new line here
$this->dataProvider2 = $dataProviderDomain;
    $this->render('index',array(
    'dataProvider1'=>$dataProviderUser,
    'dataProvider2'=>$dataProviderDomain
    ));
}

}

$this->dataProvider is now available in your view file, but don't foorget to check that it exists before using it.

The other method is to use the magic getter method from Yii.

In your model, describe a method like this;

public function getdataProvider2(){
return $this->_dataProvider2;
}

and you'll need a property;

private $_dataProvider2;
