DHTMLX integration with yii framework not working? - yii

Question

I integrated dhtmlx with yii frame work based on the instruction given in their site.( DHTMLX With YII )
here my controller file code,
include_once(YII_BASE_PATH . "/dhtmlx/connector/grid_connector.php");
include_once(YII_BASE_PATH . "/dhtmlx/connector/scheduler_connector.php");
include_once(YII_BASE_PATH . "/dhtmlx/connector/db_phpyii.php");
class EventsController extends Controller
{
public function accessRules()
{
return array(
array('allow', // allow all users to perform 'index' and 'view' actions
'actions'=>array('index','view','grid','scheduler'),
'users'=>array('*'),
),
array('allow', // allow authenticated user to perform 'create' and 'update' actions
'actions'=>array('create','update'),
'users'=>array('#'),
),
array('allow', // allow admin user to perform 'admin' and 'delete' actions
'actions'=>array('admin','delete'),
'users'=>array('admin'),
),
array('deny', // deny all users
'users'=>array('*'),
),
);
}
public function actionGrid()
{
// $this->render('grid'); //loads the 'grid' view that we will create later
$model = new Events();
$this->render('grid',array(
'model'=>$model,
));
}
public function actionGrid_data()
{
//$model = new Events;
$grid = new GridConnector(Events::model(), "PHPYii");
$grid->configure("-","event_id", "start_date, end_date, event_name");
$grid->render();
}
}

return new CActiveDataProvider($this, array(
'criteria'=>$criteria,

}
}
when I run the action grid i got the error in the popup window like below,
I don't know what is the issue?. I doubt that may be '$grid = new GridConnector(Events::model(), "PHPYii"); ' this one causes the problem.
How can I resolve this one?. Can anyone help me?.

Answer 1

Yes. I found answer, I need to edit the core extension file dhtmlx/connector/db_phpyii.php
like below, (Remove &-reference operator).
Shows – $temp[]=&$obj->getAttributes();
Should read – $temp[]=$obj->getAttributes();
Ref: http://www.dhtmlx.com/blog/?p=1648

Answer 2

Please have a look at the question: Strict Standards: Only variables should be assigned by reference PHP 5.4
Looks like you're using strict standards and passing an object with a reference operator in line 16 of /dhtmlx/connector/db_phpyii.php.
