PHP development framework Yii Framework tutorial (16) UI component StarRating example

CStarRating is mainly used for rating, showing a set of stars (5) for rating.

The basic usage is as follows

beginWidget('CActiveForm'); ?>widget('CStarRating',array('model'=>$model,'attribute'=>'rating','name'=>'rating','value'=>3,)); ?>
endWidget(); ?>

In the Controller, you can access the value of Star through $_POST['rating'], for example:

public function actionIndex(){
$model=new DataModel();$model->rating=3;if(!emptyempty($_POST['rating'])){$model->rating=$_POST['rating'];
if($model->validate()) {$this->render('response', array('model' => $model,
));return;}
}
$this->render('index', array('model' => $model,
));}

CStarRating can also be set to read-only , at this time StarRating is used to display the rating and the user cannot modify the rating. This is achieved through 'readOnly' => true,.
