        $this->database->table('comments')->insert([
            'post_id' => $postId,
            'name' => $values->name,
            'email' => $values->email,
            'content' => $values->content
        ]);

        $this->flashMessage('Děkuji za komentář', 'success');
        $this->redirect('this');
    }

}
