Your code is nice....but you forgotted only simple thing.You forgotted to give the below in your Controller "__Construct()"
你的代码很好......但你只忘记了简单的事情。你忘了在你的控制器“__Construct()”中给出以下内容
$this->load->model('your modelname');
That's it.everythng is well defind.
就是这样。一切都很好。

Add a constructor. Then it will help to call the model.
添加构造函数。然后它将有助于调用模型。
<?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();
}
}
}
