DHTMLX integration with yii framework not working?

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();
        }
}

}

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.
