APPPATH代码信号器在服务器上不工作 [英] APPPATH codeigniter doesnt work on server

问题描述

  
我有一个问题在codeigniter上传到服务器，我需要一个模型文件><？php 
 require_once（APPPATH.'libraries / MY_Model.php'）; 
 Class scroll_news_model extends MY_model 
 {
 public function __construct（）
 {
 parent :: __ construct（scroll_news）; 
} 
} 
  

这个代码在我的localhost中正常工作，在上传后遇到此错误

致命错误：require_once（）[function.require]：无法打开所需的'application / libraries / MY_Model.php'（include_path =' 。/ usr / lib / php：/ usr / local / lib / php'）在/home/arab2day/public_html/temp/arab2day/application/models/scroll_news_model.php第2行

<如果你想扩展 CI_Model 类， MY_Model.php 属于 / core 目录而不是 / libraries ，您不需要包括

这是扩展核心类的工作原理，扩展常规非必要的库稍有不同。有关详情，请参阅：

至于文字问题， Lepidosteus 提供了一个关于区分大小写和操作系统的好处，我自己遇到了这个问题几次。

i got a problem in codeigniter after i upload it to the server i am requiring a file in a model from libraries folder

<?php
require_once(APPPATH.'libraries/MY_Model.php');
Class scroll_news_model extends MY_model
{
 public function __construct()
 {
    parent::__construct("scroll_news");
 }
}

this code was working fine in my localhost but i keep getting this error after i upload it

Fatal error: require_once() [function.require]: Failed opening required 'application/libraries/MY_Model.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/arab2day/public_html/temp/arab2day/application/models/scroll_news_model.php on line 2

解决方案

If you are trying to extend the CI_Model class, MY_Model.php belongs in the /core directory rather than /libraries, and you don't need to include it - it will be loaded automatically when the base model class is loaded.

This is how extending core classes works, extending regular non-essential "libraries" is slightly different. Read more about it here:

As far as the literal problem goes, Lepidosteus makes a good point about case sensitivity and OS, I've run into this issue myself several times.
