[resolved] How To use content inside CWidget

Archives Yii 1.0.x Discussions

I've read this in the Guide:



<?php $this->beginWidget('path.to.WidgetClass'); ?>


...body content that may be captured by the widget...


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

How do i use this content?? Is there a way to use it?

Thanks

You can call ob_start() in init() and then get the body content in run() by using ob_get_clean()

It doesn't work, the text has been writed twice.

example code:



class ClockRefresh extends CWidget {





    public $time = 1000;


    public $url = null;


    public $updateAtStart = false;


    public $containerCssClass = null;





    public function init(){


        ob_start();


    }


    public function run(){


        $id = $this->getId();


        echo "<div id="$id"";


        if ($this->containerCssClass){


            echo ' class="' . $this->containerCssClass . '"';


        }


        echo '>';


        echo ob_get_clean();


        echo ('</div>');


    }


}

And the extension call is:



<?php $this->beginWidget('application.extensions.timerext.ClockRefresh', array(


    'time'=>1000,


    'url'=>$this->createUrl('site/updateItem'),


    'updateAtStart'=>true)); ?>


loading...


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

it shows: loading…



loading...


<div id="yw0"></div>

instead of:



<div id="yw0">loading...</div>

Your logic is not right here because you are also capturing the tags you render in run(). You should move those code before ob_start().

It Works!!!

Sorry to reopen this post but I have problems with my extensions, I cannot render two instances of an HTML layer from a Class in a view (http://www.yiiframework.com/extension/egmap/) explained a workaround, but why I cannot render two HTML layers even if I create two different objects from the same class?

Mind sharing your solution Sebas? Why did it work?

Thanks

Forget my last post, I have already found a solution and also mdomba pointing me for some strange HTML behaviour with GMaps. Nothing to do with ob_get_contents

Thanks anyway
