加载模型时的CodeIgniter Undefined属性 [英] CodeIgniter Undefined property when loading a model

问题描述

在尝试在codeigniter中实现非常简单的模型控制器时，我收到以下错误消息。我是该框架的新手，但据我所知，这应该可行。

I'm receiving the following errors whilst trying to implement a very simple model controller in codeigniter. I'm new to the framework but as far as I can see this should work.

我也尝试过自动加载模型。我正在自动加载数据库库。

I've also tried auto loading the model. I am autoloading the database library.

Message: Undefined property: User::$user_model

Fatal error: Call to a member function get_user() on a non-object

模型上调用成员函数get_user（）

The model

class User_model extends CI_Model
{

function __construct()
{
    parent::__construct();
}


function get_user()
{
    return "test";
}


}

控制器

class User extends CI_Controller
{

public function __construct()
{
    parent::__construct();
}

function index()
{
    $this->load->model('User_model');

    $data['value'] = $this->User_model->get_user();

    $this->load->view('user_edit', $data);
}
}

谢谢

推荐答案

我认为我已经找到问题了。我的用户控制器中有很多其他的setter方法，这些方法我一直使用，并不认为这会成为问题。

I think i've found the problem. I had some additional setter methods in my user controller which i've used all the time, didnt think they would be a problem.

    public function __set($key, $value)
{
    // Check to see that the requested attribute exists and then assign the value
    if (property_exists($this, $key))
    {
        $this->$key = $value;
    } 
}

原来我需要带下划线之一

turns out I needed to take away one of the underscores as codeigniter doesn't like it.

public function _set($key, $value)

我本应该真正包括完整的课程，但是我试图使其尽可能简单！

I should have really included the full class but I was trying to keep it as simple as possible!
