Zend Framework: Autoloading a Class Library - php

Question

I've got a class library in defined here .../projectname/library/Me/Myclass.php defined as follows:
<?php
class Me_Myclass{
}
?>
I've got the following bootstrap:
<?php
/**
* Application bootstrap
*
* #uses Zend_Application_Bootstrap_Bootstrap
*/
class Bootstrap extends Zend_Application_Bootstrap_Bootstrap
{
/**
* Bootstrap autoloader for application resources
*
* #return Zend_Application_Module_Autoloader
*/
protected function _initAutoload()
{
$autoloader = new Zend_Application_Module_Autoloader(array(
'namespace' => 'Default',
'basePath' => dirname(__FILE__),
));
$autoloader->registerNamespace('Me_');
return $autoloader;
}
/**
* Bootstrap the view doctype
*
* #return void
*/
protected function _initDoctype()
{
$this->bootstrap('view');
$view = $this->getResource('view');
$view->doctype('XHTML1_STRICT');
}
/**
* Bootstrap registry and store configuration information
*
* #return void
*/
protected function _initRegistry()
{
$config = new Zend_Config_Ini(APPLICATION_PATH .
'/configs/application.ini', APPLICATION_ENV,
array('allowModifications'=>true));
Zend_Registry::set('configuration', $config);
}
}
In my controller I try to instantiate the class like this:
<?php
class SomeController extends Zend_Controller_Action
{
public function indexAction()
{
$classMaker=new Me_Myclass();
}
}
?>
When I navigate directly to http:/something.com/projectname/some?id=1 I get the following error:
Fatal error: Class 'Me_Myclass' not found in /home/myuser/work/projectname/application/controllers/SomeController.php on line x
Any ideas?
Potentially Pertinent Miscellany:
The autoloader seems to work when I'm extending models with classes I've defined in other folders under application/library.
Someone suggested changing the 'Default', which I attempted but it didn't appear to fix the problem and had the added negative impact of breaking function of models using this namespace.

Answer 1

You class needs to be name Me_Myclass:
class Me_Myclass
{
}
Move your library folder up a level so that you have the folder structure:
/
/application
/library
/public
And then in your Bootstrap add the following to the _initAutoload():
Zend_Loader_Autoloader::getInstance()->registerNamespace('Me_');

Answer 2

you can define the autoload dir in the config.ini file like this:
autoloaderNamespaces[] = "Me_"
;You could add as many as you want Classes dir:
autoloaderNamespaces[] = "Another_"
autoloaderNamespaces[] = "Third_"
works 100%

Answer 3

I think #smack0007 means replace the contents of your _initAutoload method with Zend_Loader_Autoloader::getInstance()->registerNamespace('Me_'); so it looks like this:
protected function _initAutoload()
{
Zend_Loader_Autoloader::getInstance()->registerNamespace('Me_');
}

Not sure if this is your problem, but I just spent the last day and half trying to figure out my own similar problem (first time loading it up on Linux from Windows). Turns out I was blind to my library's folder name case.
/library
/Tlib
is not the same as (on *nix)
/library
/tlib
Class name is typically this
class Tlib_FooMe {
...
}
Hope this helps someone who is similarly absentminded.
