问题描述

你好，我只是看了第一个/ Day1屏幕录像在NettutsCodeIgniter从scracth我已经遇到一个错误，我不明白。以下是屏幕截图 http://i39.tinypic.com/14mtc0n.jpg

Hello I just watched the first/Day1 screencast on Nettuts "CodeIgniter from scracth" And I'm already running into an error I don't understand. Here's a screenshot http://i39.tinypic.com/14mtc0n.jpg

我的models\site_model.php中的代码与screencast相同

The code in my models\site_model.php is the same as the screencast

   models\site_model.php

   class Site_model extends CI_Model {  
   function getAll() {
    $q = $this->db->get('test');        
    if($q->num_rows() > 0) {
        foreach ($q->result() as $row) {
            $data[] = $row;
        }
    return $data;
    }
}

并且控制器controllers\site.php

And the controller controllers\site.php

   class Site extends CI_Controller {
function index(){
    $this-> load-> model('site_model'); 
    $data['records'] = $this-> site_model-> getAll();
    $this-> load-> view('home', $data);

}   
 }

/ p>

And here's my db info incase

 $db['default']['hostname'] = 'localhost';
 $db['default']['username'] = 'root';
 $db['default']['password'] = '';
 $db['default']['database'] = 'ci_series';
(rest is default below)

谢谢

推荐答案

您需要首先加载数据库。 Codeiginiter将不会默认为您加载。

You need to load the database first. Codeiginiter won't load it by default for you.

您可以将其添加到 /config/autoload.php like like

You can either add it to /config/autoload.php like so

$autoload['libraries'] = array('database');

或者您可以通过调用

$this->load->database();
