if(isset($_GET['option_id']) and $_GET['option_id'] > 0)
$id= $_GET['option_id'];

public function actionCreate()
{
$model = new QuestionsOptions();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->option_id]);
} else {

If you want to save multiple record use loop i suggest you to use foreach loop it is best
public function actionCreate()
{
$model = new QuestionsOptions();
if ($model->load(Yii::$app->request->post())) {
if(sizeof(array_filter($_POST['QuestionsOptions']['label'])) > 0){
foreach($_POST['QuestionsOptions']['label'] as $key => $row){
$model->setIsNewRecord(true);
$model->id = null;
$model->label = $row;
$model->save();
}
}
return $this->redirect(['view', 'id' => $model->option_id]);
} else {
return $this->renderAjax('create', [
'model' => $model,
]);
}
}
