CodeIgniter: "Unable to load the requested class"

Question

On my WAMP box, I did the following:

Added a file called /application/libraries/Foo.php
Foo.php is a class, and it's name is Foo
In /application/config/autoload.php, I added $autoload['libraries'] = array('foo');

Everything works fine. When I upload to my LAMP box, I get the following error:

Unable to load the requested class: foo

Permission of /application/libraries/Foo.php is 0755. Owner is the same as the rest of the CI files. Taking foo out from autoload makes the problem go away.

Any ideas what might be wrong?

In Windows, capitalization in paths doesn't matter. In Linux it does.

When you autoload, use "Foo" not "foo".

I believe that will do the trick.

I think it works when you take it out of autoloading because codeigniter is smart enough to figure out the capitalization in the path and classes are case independent in php.

Had the same issue. In autoload I had 'oauth2', but changed to 'OAuth2' and it worked. Thanks. – gelviis Aug 11 '12 at 13:22
in Linux what is FOO ? Is that model ? or Class or controller of view or something else ? Please be specific. – Pratik Joshi Apr 23 '15 at 06:47

I had a similar issue when deploying from OSx on my local to my Linux live site.

It ran fine on OSx, but on Linux I was getting:

An Error Was Encountered

Unable to load the requested class: Ckeditor

The problem was that Linux paths are apparently case-sensitive so I had to rename my library files from "ckeditor.php" to "CKEditor.php".

I also changed my load call to match the capitalization:

$this->load->library('CKEditor');

If you're using a linux server for your application then it is necessary to use lowercase file name and class name to avoid this issue.

Ex.

Filename: csvsample.php

class csvsample {

}
