  class Reviews extends CI_Controller
  {
    
    public function contruct__()
    {
        
        parent::__construct();
        $this->load->model('review_model');
        
        
    }
    
    public function show_list()

    {
        
        $reviews['main'] = $this->review_model->get_info();
        
        if($reviews == TRUE)
        {
            
            $this->display_lib->reviews($reviews);
            
        }
        
        else
        {
            
            echo "Database error occured";
            
        }
        
            
    }
    
    
    
  }

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


 class Reviews_model extends Crud
 {
    
    
    public function get_info()
    {
        
        $this->db->order_by('reviews_id','desc');
        $this->db->limit(15);
        $query = $this->db->get('reviews');
        return $query->result_array();
        
        
    }
