How to include a library to a Zend Framework 2 application using namespace based autoloading?
Solution 1
Edit init_autoloader.php
and change the if ($zf2Path) {
section to be:
if ($zf2Path) {
if (isset($loader)) {
$loader->add('Zend', $zf2Path);
} else {
include $zf2Path . '/Zend/Loader/AutoloaderFactory.php';
Zend\Loader\AutoloaderFactory::factory(array(
'Zend\Loader\StandardAutoloader' => array(
'autoregister_zf' => true,
'namespaces' => array(
'MyNamespace' => __DIR__ . '/vendor/MyNamespace',
),
)
));
}
}
Note the addition of the MyNamespace
key within the Zend\Loader\StandardAutoloader
section.
Solution 2
In addition to Rob's answer, some other ways to autoload a custom library
First, make sure your folder structure is psr0 compliant
A typical structure for the mythical psr0 compliant MyNamespace library used in the examples
vendor/
MyNamespace/
lib/
MyNamespace/
FooClass.php
BarClass.php
Include from a Module.php file using getAutoloaderConfig
public function getAutoloaderConfig()
{
return array(
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
'MyNamespace' => __DIR__ . '/../../vendor/MyNamespace/lib/MyNamespace',
),
),
);
}
Directly in index.php
using the AutoloaderFactory
to configure the StandardAutoloader
// Setup autoloading
require 'init_autoloader.php';
Zend\Loader\AutoloaderFactory::factory(array(
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
'MyNamespace' => __DIR__ . '/../vendor/MyNamespace/lib/MyNamespace',
),
)
));
You could even do the same in a ./config/autoload/ file
<?php
// file ./config/autoload/namespaces.local.php
Zend\Loader\AutoloaderFactory::factory(array(
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
'MyNamespace' => __DIR__ . '/../../vendor/MyNamespace/lib/MyNamespace',
),
)
));
A further alternative to include your lib is to edit vendor/composer/autoload_namespaces.php
<?php
// autoload_namespaces.php generated by Composer
$vendorDir = dirname(__DIR__);
$baseDir = dirname($vendorDir);
return array(
'Zend\\' => $vendorDir . '/zendframework/zendframework/library/',
'MyNamespace\\' => $vendorDir . '/MyNamespace/lib/',
);

I created a subfolder
MyNamespace
in/vendor/
(is it the correct place for own libraries?) and want to use classes likeMyNamespace\Mvc\Router\MyCustomRouter
in my application. How can I include this library to my namespace based autoloading?-

-
automatix over 10 yearsI've tried so, how here shown (with
Module#getAutoloaderConfig()
and'MyNamespace' => __DIR__ . '/../../vendor/MyNamespace'
), but my classes cann still not be found. -
Crisp over 10 yearsDid you create a Module.php file in
/vendor/MyNamespace/
to do that? -
automatix over 10 yearsNo, I didn't. But it's not a Module, it's a library -- like ZF. The ZF library folder also has no
Module
class in it. -
Crisp over 10 yearsThe ZF library uses the standard autoloader, the accepted answer on the linked page describes adding your own library using zends autoloader by placing the code in index.php (obviously change the namespace and path to match your own lib)
-
Crisp over 10 yearsThere's actually a lot of ways to do this. You could just add your namespace and path to
vendor/composer/autoload_namespaces.php
(assuming composer is in use). Honestly though, if the lib is going to be used with Zend Mvc, why not make it a module? The skeleton app is set up to look for modules invendor
anyway. -
automatix over 10 yearsYes, it would be a good simple possiblity to the library as module, but it is not a module. OK, I've tried
vendor/composer/autoload_namespaces.php
out ('MyNamespace' => $vendorDir . '/MyNamespace',
). The error is still there. -
automatix over 10 yearsIf I add
'MyNamespace' => __DIR__ . '/../../vendor/MyNamespace',
to the array inApplication\Module#getAutoloaderConfig()
and/orOtherModule\Module#getAutoloaderConfig()
and call a class from the library (use MyNamespace\Path\To\MyClass; $test = new MyClass();
) in a view, the server returns anerror 502
. -
Crisp over 10 yearssounds like your namespace isn't psr0 compliant, assuming a path of
vendor/MyNamespace/src/MyNamespace
for composersautoload_namespaces
you would use'MyNamespace' => $vendorDir . '/MyNamespace/src/'
, and in a modulesgetAutoloadConfig()
it would be'MyNamespace' => __DIR__ . '/../../vendor/MyNamespace/src/MyNamespace'
-
automatix over 10 yearsI had defined the incorrect library path:
'MyNamespace' => $vendorDir . '/MyNamespace',
for the folder/vendor/MyNamespace
. The correct path for this folder would be'MyNamespace' => $vendorDir,
. Now I've corrected this:'MyNamespace' => $vendorDir . '/MyNamespace/library',
for/vendor/MyNamespace/library/MyNamespace
and it works. Thank you for your help! -
automatix over 10 yearsPlease make an answer from your comment with
autoload_namespaces
. It will be usefull for other and I'll get a possibility to thank you in form of an answer-acceptation.
