Tạo controller trong codeigniter 3

Tạo controller trong codeigniter 3

Trong bước này, chúng ta sẽ tạo controller Item để hiển thị danh sách, thêm mới, cập nhật và xóa. Vì vậy hãy tạo tệp Item.php trong application/controller/Item.php theo đường dẫn này và với đoạn code như sau:

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Item extends CI_Controller {

   public $itemCRUD;

   /**
    * Get All Data from this method.
    *
    * @return Response
   */
   public function __construct() {
      parent::__construct(); 

      $this->load->library('form_validation');
      $this->load->library('session');
      $this->load->model('ItemModel');

      $this->itemCRUD = new ItemModel;
   }

   /**
    * Hien thi tat ca data
    *
    * @return Response
   */
   public function index()
   {
       $data['data'] = $this->itemCRUD->get_items();

       $this->load->view('theme/header');       
       $this->load->view('items/list',$data);
       $this->load->view('theme/footer');
   }

   /**

   public function show($id)
   {
      $item = $this->itemCRUD->find_item($id);

      $this->load->view('theme/header');
      $this->load->view('items/show',array('item'=>$item));
      $this->load->view('theme/footer');
   }

   /**

   public function create()
   {
      $this->load->view('theme/header');
      $this->load->view('items/create');
      $this->load->view('theme/footer');   
   }

   public function store()

        $this->form_validation->set_rules('description', 'Description', 'required');

        if ($this->form_validation->run() == FALSE){
            $this->session->set_flashdata('errors', validation_errors());
            redirect(base_url('item/create'));
        }else{
           $this->itemCRUD->insert_item();
           redirect(base_url('item'));
        }
    }

   /**

   public function edit($id)

       $this->load->view('theme/header');
       $this->load->view('items/edit',array('item'=>$item));
       $this->load->view('theme/footer');

   /**
