【问题描述】:
为什么我不能访问它?
my model
News_model.php :
<?php
class News_model extends CI_Model
{
public function __construct()
{
$this->load->database();
}
public function get_news(){
$query = $this->db->get['news'];
return $query->result_array();
}
}
?>
my Controller
news.php :
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class News extends CI_Controller {
public function __construct (){
parent::__construct();
$this->load->model('news_model');
$this->load->helper('url_helper');
}
public function index()
{
$data['news'] = $this->news_model->get_news();
$data['title'] = 'arsip';
$this->load->view('news/index', $data);
}
}
?>
my view
news/index.php
<?php
foreach ($news as $news_item) { ?>
<h1><?php echo $news_item['title']; ?> </h1>
// <p><?php echo $news_item['text']; ?> </p>
<? } ?>
?>
routes :
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
$route['news'] = 'news';
$route['default_controller'] = 'halaman/view';
$route['(:any)'] = 'halaman/view/$1';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
然后访问 http://localhost/codeigniter/index.php/news 输出是:

【问题讨论】:
-
应该是这样 $this->db->get('news');
