php - CodeIgniter HMVC data not passing from one function to another -


i passing function _homepage index not pass $data['articles'] it. can 1 me solve this? code updated 

      public function index(){     $mydata = array();     $this->mydata['menu'] = $this->mdl_page->get_nested();     $this->mydata['page'] = $this->mdl_page->get_by(array('slug' => (string) $this->uri->segment(1)), true);     count($this->mydata['page']) || show_404(current_url());      //fetch page data     $method = '_' . $this->mydata['page']->template;     if (method_exists($this, $method)) {         $this->$method();     }     else {         log_message('error', 'could not load template ' . $method .' in file ' . __file__ . ' @ line ' . __line__);         show_error('could not load template ' . $method);     }     $this->mydata['subview'] = $data['page']->template;     //dump($data);     $this->load->view('_main_layout', $this->mydata);  }  private function _page(){     dump('welcome page template'); } private function _homepage(){     $this->load->model('admin/mdl_articles');     $this->db->limit(6);     $this->mydata['articles'] = $this->mdl_articles->get();     //dump($data['articles']);  } private function _news_archive(){     dump('welcome newspage template'); }

you should instead create private array property 

private mydata = array();

in _homepage method, contents should be: 

private function _homepage(){     // ...     // target class scope property     $this->mydata['articles'] = $this->mdl_articles->get();

and change $data variable $this->mydata in index method , pass view this:

$this->load->view('_main_layout', $this->mydata);
