इसे आजमाएं:
Yii::$app->db->createCommand("UPDATE room_types SET total_booked=total_booked+1 WHERE room_type = '$model->room_type' ")->execute();
या
public function actionCreate()
{
$model = new CreateBookings();
if ($model->load(Yii::$app->request->post())) {
$RoomType = new room_types(); // room type replace with model name
$RoomType->updateCounters(['total_booked' => 1]);
$model->save();
return $this->redirect(['view', 'id' => $model->id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
