【中文标题】致命错误：找不到类“Modelmyaccount”【英文标题】：Fatal error: Class 'Modelmyaccount' not found 【发布时间】：2012-11-21 06:27:57 【问题描述】：我正在使用 php 创建一个电子商务网站，并通过 XAMPP 加载。但是我遇到了以下错误：致命错误：找不到类'Modelmyaccount'
我曾尝试使用启用 XDebug 的 NetBeans 进行调试，但遇到了以下调用堆栈。
Call Stack
1. main( ) ..\index.php:0
2. require_once( 'E:\xampp\htdocs\promotion\system\codeigniter\CodeIgniter.php' ) ..\index.php:117
3. myshop->__construct( ) ..\CodeIgniter.php:201
4. CI_Loader->model( ???, ???, ??? ) ..\myshop.php:7
我已验证该类确实存在，但它似乎无法识别它。
下面以粗体突出显示的是它无法找到要存储到 $name 中的类名的部分
if ( ! class_exists('Model'))
load_class('Model', FALSE);
**require_once(APPPATH.'models/'.$path.$model.EXT);**
$model = ucfirst($model);
$CI->$name = new $model();
$CI->$name->_assign_libraries();
$this->_ci_models[] = $name;

【问题讨论】：
如果您使用的是 Unix 系统，请注意名称大小写 我使用的是 Windows 7 系统。同一文件夹中的其他类能够通过。但是某些课程不会这样做。这是“ModelMyAccount”的类之一，但是我已将其更改为“modelmyaccount”。但仍然没有工作。有没有我可能错过的地方？ 你是说其他模型加载正常吗？你检查错别字了吗？ 1.你是如何实例化类和 2。你的类在实例化中是如何拼写的，即。类 ModelMyAccount .....？ 我用记事本++打开了所有的.php文件，找到'ModelMyAccount'并用'modelmyaccount'替换它。存储在我的应用程序目录中的 .php 文件也具有名称 modelmyaccount.php 【参考方案1】：这可能会有所帮助： CodeIgniter User Guide - Models
如果您查看“模型剖析”，您会发现您需要更正 CodeIgniter 的命名约定才能正确找到您的模型。你的类名必须首字母大写，如下所示：
class Modelmyaccount extends Model
此外，如果您想正确遵循 CodeIgniter 命名约定；你应该将你的文件命名为my_account_model.php。另外，相应地更改类名，如下所示：
class My_account_model extends Model
此外，您使用的是哪个版本的 CodeIgniter？你的模型应该扩展CI_Model，或者如果你使用你自己的模型类扩展，它应该是MY_Model，除非你在config.php文件中设置不同的前缀。
因此，如果您使用的是 2.1.3 版本，您的模型类声明应如下所示：
class My_account_model extends CI_Model
将CI_ 替换为您使用的前缀。
