I need to use autoloading for my custom classes in Zend Framework 2.0. My custom library located in /vendor/Garvey/library/Garvey
. I have a simple extended AbstractTable class in /vendor/Garvey/library/Garvey/Db/Table/AbstractTable.php
:
<?php
namespace Garvey\Db\Table;
use Zend\Db\Table\AbstractTable;
abstract class AbstractTable extends AbstractTable
{
public function getItemById($id)
{
}
}
In the index.php I have the following code:
require_once 'vendor/ZendFramework/library/Zend/Loader/AutoloaderFactory.php';
Zend\Loader\AutoloaderFactory::factory(array('Zend\Loader\StandardAutoloader' => array(
'prefixes' => array(
'Garvey' => 'vendor/Garvey/library/Garvey',
)
)));
But I have the following error. What I have missed?
Fatal error: Class 'Garvey\Db\Table\AbstractTable' not found
Thank you in advance.
Your original index.php would also worked if you changed the 'prefixes' key to 'namespaces' and specify path like below:
Zend\Loader\AutoloaderFactory::factory(array('Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
'Garvey' => dirname(__DIR__) . '/vendor/Garvey',
)
)));
Or you can defime method in Module.php
public function getAutoloaderConfig()
{
$return = array(
'Zend\Loader\ClassMapAutoloader' => array(
__DIR__ . '/autoload_classmap.php'
),
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
'Garvey' => __DIR__ . '/../../vendor/Garvey/library/Garvey',
)
)
);
}
But I would not recommend it. Since ZF2 purpose all centered about speed in autoloading the best way is to use class_map style to load your classes. It will work much quicker at the end but require additional work. You can to register every class in you class_map file.
You can create class_map.php in the root of your library and place there
<?php
return array(
'Garvey\Db\Table\AbstractTable' => __DIR__ . '/Garvey/Db/Table/AbstractTable.php',
);
And add there as many classes as you use. And in getAutoloaderConfig() you can add you classmap
public function getAutoloaderConfig()
{
$return = array(
'Zend\Loader\ClassMapAutoloader' => array(
__DIR__ . '/autoload_classmap.php',
__DIR__ . '/../../vendor/Garvey/library/Garvey/class_map.php',
),
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
)
)
);
}
Matthew Weier O'Phinney explains in this video that there are now 3 methods for autoloading :
- ZF1-style include_path autoloader ( old zf1 method, not recommended )
- Per-namespace/prefix autoloading ( new zf2 method, better )
- Class-map autoloading ( recommended and the fastest )
A class-map generator utility is mentioned in the docs that will take care of writing the /vendor/vendor_name/library/autoload_classmap.php
for you.
The solution you found is similar to the one Matthew mentions in the video for the Per-namespace/prefix autoloading. Following the code structure in ZendSkeletonApplication, that code would go in the /init_autoloader.php
file, rather than in the /public/index.php
file.
I have found the answer. Put this in your index.php:
require_once 'vendor/ZendFramework/library/Zend/Loader/StandardAutoloader.php';
$loader = new Zend\Loader\StandardAutoloader();
$loader->registerNamespace('Garvey', realpath('vendor/Garvey/library/Garvey'));
$loader->register();
Have a quick look at this post.
Now next step is add some code into our custom library.
First of all open a file ./vendor/Garvey/autoload_classmap.php
return array(
'Garvey\Module' => __DIR__ . '/Module.php',
'Garvey\Db\Table' => __DIR__ . '/library/Garvey/Db/Table/AbstractTable.php',
)
Next is ./vendor/Garvey/Module.php
namespace Garvey;
use Zend\ModuleManager\Feature\AutoloaderProviderInterface;
class Module implements AutoloaderProviderInterface
{
public function getAutoloaderConfig()
{
return array(
'Zend\Loader\ClassMapAutoloader' => array(
__DIR__ . '/autoload_classmap.php',
),
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
__NAMESPACE__ => __DIR__ . '/library/' . __NAMESPACE__,
),
),
);
}
}
Now inside your library create a file inside a folder:
./vendor/Kdecom/library/Kdecom/Db/Table/AbstractTable.php
One final thing that we need to do which is add this library into your application.config.php
file.
So your application.config.php
file will looks something like this way...
return array(
'modules' => array(
'Application',
'Garvey'
),
'module_listener_options' => array(
'config_glob_paths' => array(
'config/autoload/{,*.}{global,local}.php',
),
'module_paths' => array(
'./module',
'./vendor',
),
),
);
