Try this in your controller:

public function actionCreate()
{
    $model = new Account();

    if (isset($_POST['Account']){

        $model->attributes = $_POST['Account'];
        $model->userid = 123;

        /* in case you had errors
        // $model->validate();
        // var_dump($model->getErrors());
        */

        if($model->save()){

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

        return $this->render('create', [
            'model' => $model,
        ]);
    }
}
