Remove segment from url in multi language site

It looks like you are trying to add and view the result within the same method (It/Main::article). Have you tried seperating them? Plus, can you see any response data from your controller, I mean for example:

PHP Code:

$slug = \Config\Services::request()->uri->getSegment(2);

echo $slug;
die(); 


Hi @demyr!
I have a view called blog with categories and articles for each category.

blog method:

PHP Code:

    public function blog()
    {
        $data['title'] = '';
        $data['metaDescription'] = '';
        $data['articles'] = $this->articlesModel->orderBy('id', 'DESC')->where('status', 1)->findAll();
        $data['categories'] = $this->categoriesModel->where('lang', 'it')->findAll();

        echo view('blog', $data);
    } 


article method:

PHP Code:

public function article()
  {
    $slug = \Config\Services::request()->uri->getSegment(2);
    $data['article'] = $this->articlesModel->where('slug', $slug)->first();
    $dataArticle = $data['article'];
    $data['title'] = $dataArticle['meta_title'];
    $data['metaDescription'] = $dataArticle['meta_description'];
    $data['images'] = $this->imagesGalleryModel->where('article_id', $dataArticle['id'])->findAll();
    // // //
    $data['latestArticles'] = $this->articlesModel->orderBy('id', 'DESC')->where('status', 1)->findAll(5);
    // // //
    $builder = $this->db->table('tbl_articles');
    $builder->orderBy('hits', 'DESC');
    $data['hitsArticles'] = $builder->get(10);
    // // //
    $builder = $this->db->table('tbl_articles');
    $builder->set('hits', 'hits+1', FALSE);
    $builder->where('slug', $slug);
    $builder->update();

    return view('article', $data);
  } 


Routes:

PHP Code:

// TEST
$routes->add('(:any)/it/', 'It/Main::article/$1');
$routes->get('{locale}/(:segment)', 'It/Main::article/(:segment)');

// GOOD WITH WORD ARTICLE IN LINK: mysite.com/it/article/slug
// $routes->add('(:any)/it/article', 'It/Main::article/$1');
// $routes->get('{locale}/article/(:any)', 'It/Main::article');

$routes->get('{locale}/blog', 'It/Main::blog'); 


The error is the same: Trying to access array offset on value of type null

I have this code in another site with one language, CI 4.0.4 and PHP 7.4 and all works fine!

I tried your code and the uri segment is correct i can see the answer from my controller.
