远程服务器中的 Codeigniter HMVC return 错误

Question

（我的英文不正确）

拜托，我在本地使用 codeigniter 中的 HMVC，但在我的远程服务器中出现错误

An uncaught Exception was encountered Type: RuntimeException

我的文件看起来像：

->Modules

--->home

--------->controllers

-------------->Home.php

--------->models

-------------->home_model.php

--------->views

-------------->contact.php

当我将模型文件更改为“Home_model.php”时，出现了这个新错误

我使用了这个 HMVC https://bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc

我认为问题出在我尝试使用数据库时，但我不知道在哪里。

Answer 1

模型应该是 UCfirst，从你显示的文件结构来看它不是。

因此，将 home_model.php 改为 Home_model.php。

同样适用于 class 声明，您需要：

class Home_model extends CI_model

而不是：

class home_model extends CI_model

我假设您的本地环境是 windows 并且游览远程环境是 linux 这就是为什么会发生这种情况，因为 linux 区分大小写而 windows没有。

所以好好看看你所有的 classes（模型和控制器）它们都应该遵循这个模式。

Answer 2

您需要加载数据库。

class Home_model extends CI_Model {

    public function __construct() {
        parent::__construct();
        $this->load->database();

    }

}

或

$this->load->model('home_model', NULL, TRUE);

*第三个参数在模型中为您加载数据库
