Communication problem between ECHO and ALERT

Hi, I’m using the CStarRating class but I can’t show in alert() the data I pass by echo() via an action.

Here the code of the widget:

$this->widget('CStarRating', array(

    'model' => Offers::model(),

    'attribute' => 'rating',

    'readOnly' => false,

    'htmlOptions' => array('id'=>'offer_'.$data->id),

    'maxRating' => 5,

    'callback' => '

        function() {

            $.post(

                "'.Yii::app()->createUrl('offers/index').'",

                "action=rate&stars="+$(this).val()+"&offerID='.$data->id.'",

                function(msg) { alert(msg); }

            );

        }

    ',

));

and here the code of the action:

if(isset($_POST['action'])) {

    if($_POST['action'] == 'rate') {                

        $stars = filter_input(INPUT_POST, 'stars', FILTER_SANITIZE_NUMBER_INT);

        $offerID = filter_input(INPUT_POST, 'offerID', FILTER_SANITIZE_NUMBER_INT);

        $offer = Offers::model()->findByPk($offerID);

        $rating = $offer->rating;

        $reviews = $offer->reviews;

        $offer->rating = round(($rating * $reviews + $stars) / ($reviews + 1));

        $offer->reviews = $reviews + 1;

        $offer->save();

        echo $offer->rating;

    }

}

Instead of showing $offer->rating the alert shows the whole page source code.

What’s the problem? Thank you for your support.

The problem was render() before the echo() statement

Now I’ve moved render() at the action bottom and put Yii::app()->end() after the echo() and it works

Hello,

Maybe some pointers?

• Have you checked the ajax request’s form data in Firebug? Are they what you intended to post?

• Have you checked the results of your ajax request in Firebug? Are they really the source code like you see in your alert box?

Edit: Ok I see you’ve solved it, but there was no “render” in your originally posted code

Yes, you’re right, my fault, the render() was before the initial if():

if(isset($_POST['action'])) {
