CodeIgniter $ this-> load-> model（）不工作 [英] CodeIgniter $this->load->model() not working

问题描述

Im using codeigniter 2.1.2 and here's my situation now now。我有一个名为math.php的模型在C：\wamp\www\cr8v\application\models。我试图从我的控制器加载这个从C：\wamp\www\cr8v\application\controllers\site.php但是得到这个错误：

Im using codeigniter 2.1.2 and here's my situation right now. I have a model named math.php in C:\wamp\www\cr8v\application\models. I am trying to load this in my controller from C:\wamp\www\cr8v\application\controllers\site.php yet im getting this error:

Unable to locate the model you have specified: math_model

这里是math.php的内容

Here's the content of math.php

 <?php
    class Math_model extends CI_Model(){
        public function add(){
            return 1+1;
        }
    }
 ?>

这里是我的site.php的内容

And here's the content of my site.php

<?php
    class Site extends CI_Controller{
        public function index(){
            $this->addstuff();
        }

        public function addstuff(){
            $this->load->model("math_model");
            echo $this->math->add();
        }
    }  
?>

我在youtube的教程中跟着这个。然而，它不给我我想要的输出。我试过谷歌搜索和阅读其他相关的问题，但这些信息是不够的。请帮助。

I followed this in a tutorial in youtube. yet, it doesnt give me my desired output. Ive tried googling about it and read other related questions with this, however those information are not enough. Please help.

推荐答案

名称需要在所有地方相同：

The name needs to be the same in all places:

此处：

class Math_model extends CI_Model {
   // your model
}

此处：

$this->load->model("math_model");

使用时：

$this->math_model->add();

和：在您的文件系统中。所以将 math.php 重命名为 math_model.php ，它会工作。

And: in your file system. So rename math.php to math_model.php and it will work.
