我正在自动加载配置中已经存在的库site_model，这是我得到的错误：
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Site::$Site_model
Filename: controllers/site.php
Line Number: 16
Fatal error: Call to a member function add_record() on a non-object in /Applications/XAMPP/xamppfiles/htdocs/BLOCK/application/controllers/site.php on line 16
控制器：
<?php
class Site extends CI_Controller {
function index(){
$this->load->view('option_view');
}
function create(){
$data = array(
'subject' => $this->input->post('subject'),
'body' => $this->input->post('body')
);
$this->Site_model->add_record($data);
$this->index();
}
}
?>
型号：
<?php
class Site_model extends CI_Model {
function get_records()
{
$query = $this->db->get('items');
return $query->result();
}
function add_record()
{
$this->db->insert('items', $data);
$return;
}
function update_record()
{
$this->db->where('id', 1);
$this->db->update('items', $data);
}
function delete_record()
{
$this->db->where('id', $this->url->segment(3));
$this->db->delete('items');
}
}
?>
和视图：

<?php echo form_open('site/create'); ?>
<p>
</label for="subject">Subject</label>
<input type="text" name="subject" id="subject">

<input type="text" name="body" id="body">
</p>
<p>
<input type="submit" value="Submit">

</html>
你们怎么看？
非常感谢
$this->load->model('Site_model'); # <- add this
$this->Site_model->add_record($data);
您的代码很好。。。。但你们放弃的只是一件简单的事。您放弃在控制器"__Construct（）"中给出以下内容
$this->load->model('your modelname');
就是这样，一切都很清楚。
添加一个构造函数。然后调用模型会有所帮助。
<?php
class some_controller extends CI_Controller{
public function __construct()
{
parent::__construct();
$this->load->model('site_model');
}
function index()
{
$this->load->view('your_view');
}
function create()
{
$data = array(
'test1' => $this->input->post('test1'),
'test2' => $this->input->post('test2')
);
$this->site_model->add($data);
$this->index();
}
}
添加"Site_model"；在config-autoload.php上，如下所示：
$autoload['model'] = array('Site_model');
