Problem Creating Cwidget

Yii 1.1 General Discussion
1

I am having a problem trying to create a simple widget. Debugging it, I found that it crashes when requiring the file in YiiBase.

Strangely enough, if I convert the CWidget to a CPortlet it works fine. This would seem to indicate that probably not a permissions or file path issue.

Here is the code that creates the widget in my view:

<?php $this->widget('TaskBar', array('action'=>$action)); ?>

Here is the CWidget code:

class TaskBar extends CWidget

{

public $action;





public function init()


{


}





protected function run()


{


    $this->render('_taskBar', array('action'=>$this->action));


}

}

Here is the code that works just fine:

Yii::import(‘zii.widgets.CPortlet’);

class TaskBar extends CPortlet

{

public $action;





public function init()


{


    parent::init();


}





protected function renderContent()


{


    $this->render('_taskBar', array('action'=>$this->action));


}

}

What am I doing wrong?

You have to call parent::init() :)

Thanks for the reply. I added the call the to parent::init() and unfortunately it had no effect. It still crashes while the widget is being created.

public function init()


{


    parent::init();


}

I’m sorry. I was wrong.

In fact we don’t need to call parent::init() … CWidget::init() does nothing.

(Click on the "show" link to see the source.)

On the other hand, CPortlet is starting output buffering in init().

And it flushes the buffer in run().

So, how do you call your widget in your view?

If you are expecting your widget to function like this:




$this->beginWidget();

... contents ...

$this->endWidget();

Then you have to do the same thing as CPortlet does.
