CodeIgniter

HeartOfProgrammer, 2015-11-16 22:00:52

The problem is that codeigniter does not display data from the database,
in my controller it is written like this:

function index()
  {
    $this->load->view('header_view');
    $this->load->view('main_view');
    $this->load->view('footer_view');
  }

My view: main_view

<!DOCTYPE html>
<html lang="ru">
<head>
  <meta charset="UTF-8">
  <title>Главная страница</title>
</head>
<body>
  <div class="container">
    <div class="item_news">
          <?php foreach($articles as $item):?>
        <p><?=$item['title']?></p>
        <p><?=$item['text']?></p>
        <p><?=$item['date']?></p>
      <?endforeach;?>
      <?=$this->pagination->create_links();?>
    </div>
  </div>
</body>
</html>

My model:

defined('BASEPATH') OR exit('No direct script access allowed');

class Articles_model extends CI_Model {
  function get_articles($num, $offset)
  {
    $this->db->order_by('id', 'desk');
    $query = $this->db->get('articles', $num, $offset);
    return $query->result_array();
  }

  function add_article($data)
  {
    $this->db->insert('articles',$data);
  }

  function edit_article($data)
  {
    $this->db->where('id', '5');
    $this->db->update('articles',$data);
  }

  function delete_article($id)
  {
    $this->db->where('id',$id);
    $this->db->delete('articles');
  }
}

Errors shown by codeigniter:

A PHP Error was encountered
Severity: Notice
Message: Undefined variable: articles
Filename: views/main_view.php
Line Number: 10
Backtrace:

PS I'm confused about this framework, just started learning it. Do not judge strictly, just tell me where my mistake is.

function index()
  {
// Подгружаешь модель
$this->load->model('articles_model');
// выбираешь артикли, сколько тебе нужно
$this->data['articles'] = $this->articles_model->get_articles(10, 0);

    $this->load->view('header_view');
    $this->load->view('main_view');
    $this->load->view('footer_view');
  }

It is written: "Message: Undefined variable: articles".
