PHP development framework Yii Framework tutorial (40) Zii component-SliderInput example

CJuiSliderInput displays a slider, which also encapsulates the JUI slider plug-in and can be used in a Form as a user input UI component.

The basic usage is as follows:

beginWidget('CActiveForm'); ?>
 
errorSummary($model); ?>
widget('zii.widgets.jui.CJuiSliderInput', array(
'model'=>$model,
'attribute'=>'size',
'name'=>'my_slider',
'value'=>50,
'event'=>'change',
'options'=>array(
'min'=>0,'max'=>100,
'slide'=>'js:function(event,ui){
$("#amount").text(ui.value);}',
),'htmlOptions'=>array(
'style'=>'width:200px; 
float:left;'),
));
 ?>
50
endWidget(); ?>

After the user submits, use result.php to display the value entered by the user. The DataModel is defined here as follows:

class DataModel extends CFormModel{public $size;
public function rules(){return array(array('size', 'safe'),);}}

Modify the indexAction method of SiteController:

public function actionIndex(){
$model=new DataModel();
$model->size=50;
if(!emptyempty($_POST['DataModel'])){
$model->attributes=$_POST['DataModel'];
if($model->validate()){
$this->render('result', array('model' => $model,));
return;}
}
$this->render('index', array('model' => $model,
));}
