javascript - 如何在 yii2 中的单个 Controller 中使用多个场景？

Question

大家好，如何在 yii2 中的单个 Controller 操作中使用多个场景。i 有一个 onchange 下拉列表，依赖于 onchange 表单字段将发生变化。所以我使用了场景，但 Controller 只接受一种场景。是否可以在一个场景中使用多个场景单一操作。请帮忙..

Model:

 public function rules()
    {
        return [
            //[['discount_type', 'discount_name', 'discount_percentage', 'discount_from_quantity','discount_to_quantity' ,'discount_start_date', 'discount_end_date', 'discount_status', 'access_code', 'code_discount', 'no_of_tickets', 'status','ticket_name'], 'required'],
            [['discount_type','ticket_name'],'required'],
            [['event_id', 'ticket_id', 'discount_from_quantity','discount_to_quantity', 'no_of_tickets', 'status'], 'integer'],
            [['discount_type', 'discount_status','ticket_name'], 'string'],
            [['discount_start_date', 'discount_end_date', 'timestamp'], 'safe'],
            [['discount_name'], 'string', 'max' => 255],
            [['discount_percentage', 'code_discount','access_code'], 'string', 'max' => 100,],
            [['discount_start_date', 'discount_end_date','access_code','no_of_tickets'],'required','on' => 'access'],
            [['discount_start_date', 'discount_end_date','code_discount','no_of_tickets','discount_percentage'],'required','on' => 'code'],
            [['discount_name','discount_percentage','discount_start_date', 'discount_end_date','no_of_tickets','discount_from_quantity','discount_to_quantity'],'required','on' => 'group'],
            ];
           
    }

Controller:

public function actionCreate($id)
    {
		//echo $id;
        $model_discount= new EventticketDiscount();
       $model_discount->scenario = 'code';
        $model_ticketid = new EventTicket_ex();
        
        $ticketid=$model_ticketid->find()->where(['event_id'=>$id])->one();
        
        $ticketname=ArrayHelper::map($model_ticketid->find()->where(['event_id'=>$id])->all(),'ticket_id','ticket_name'); 
        
   
        if ($model_discount->load(Yii::$app->request->post())) {
			
			$model_discount->attributes=$_POST['EventticketDiscount'];

         if(isset($_POST['EventticketDiscount']['ticket_name']) && $_POST['EventticketDiscount']['ticket_name']!==array())
            $model_discount->ticket_name=implode(',',$_POST['EventticketDiscount']['ticket_name']);
            
           
		    $model_discount->event_id = $id;
		    $model_discount->ticket_id = $ticketid->ticket_id;
			$model_discount->save();

    
            return $this->redirect(['view', 'id' => $model_discount->discount_id]);
        } else {

Answer 1

您必须在事件表单的选项中设置场景选项。如果你愿意的话，你可以用 jquery 来改变它。还要为表单添加一个 ID，以便客户端验证也能正常工作。
