Multilingual site with dynamic URL in Yii2 how?

Question

Yii

Hello!
the task is this: A multilingual site ... and a dynamic URL for each post, category and page
, that is, something like this page about (en), o-nas (ru), etc.
when the language changes, the weight of the page should change, not loss of position,
this is approximately so: there was site.com/ru/o-nas -> site.com/en/about
for this I have already done something

'urlManager' => [
  'enablePrettyUrl' => true,
  'showScriptName' => false,
  'class'=>'app\components\LangUrlManager',
  'rules' => [
    'login'=>'site/login',
    'logout'=>'site/logout',
    [
      'pattern' => '/<url1:\w+>',
      'route' => 'site/get-page',
    ],
    [
      'pattern' => '/<url1:\w+>/<url2:\w+>',
      'route' => 'site/get-page',
    ],
  ],
],

in the controller
(Url is not a helper here, but a model)

public function actionGetPage($url1,$url2=NULL){
  // debug($url1); die;
  if(isset($url1)){
    $url = Url::find()->where(['url'=>$url1,'language'=>Yii::$app->lang])->asArray()->one();
    if(!empty($url)){
      if($url['type'] == 'category'){
        return Yii::$app->runAction('/site/category/',['id'=>$url['parent_id']]);
      }
    }
  }
  header($_SERVER["SERVER_PROTOCOL"]." 404 Not Found"); 
  return $this->render('error');
}

everything works fine, but the problem is that there is a url: /o_nas then everything works, but if /o-nas then gives out 404
, did I miss something? what is the problem?
By the way, if there is another option for you to solve this problem, then tell
me (sorry for the mistakes)

Answer 1

replace \w+ everywhere with [a-zA-Z0-9\-_]*
and read about regular expressions ....
