How to do search in yii2 website?

Question

Yii

Hello, help me solve the problem. Each user has his own personal profile id. The site has a special page where you can find information about the user when you enter your profile id in the field. Id of the profile is given during registration (string of 10 digits). I've been trying to solve this problem all day

Thanks Dmitry .
public function actionIndex()
{
$q = Yii::$app->request->get('id_cart');
if ($q){
$query = Clients::find()->where('id_cart=:id', [':id' => $q])->one();
return $this->render('index', compact('query'));
}else{
Yii::$app->session->setFlash('error', 'Error... Please try again...');
return $this->refresh();
}
}
