      <span class="postinfo"> Posted by <a href="">Dylan</a> on 07.09.06</span>
      <p>Lorem ipsum dolor set amir <a href="">tolos</a> and tacos for plenty to see. jack is the orange sub marine, by any means I found my plans. </p>
    </div>
  </div>

Controller:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Welcome extends CI_Controller {
    public function index()
    {
        $this->load->view('header_view');
        $this->load->view('menu_view');
        $this->load->view('categories_view');
        $this->load->view('useful_sites_view');
        $this->load->model('mat_model');
        $data = array();
        $data['news'] = $this->mat_model->get_mat(); 
        $this->load->view('content_view',$data);
        $this->load->view('footer_view');
    }   
}
?>

So where is my mistake? I can’t find it.

Answer 1

You are not returning anything from your function.

You probably want something like:

public function get_mat()
  {
    $query = $this->db->get('materials');
    return $query->result_array(); 
  }
