Using Composer's Autoload

Question

I have been looking around the net with no luck on this issue. I am using composer's autoload with this code in my composer.json:

"autoload": {     "psr-0": {"AppName": "src/"} } 

But I need to autoload at a higher level than the vendor folder.

Doing something like this does not work:

"autoload": {     "psr-0": {"AppName": "../src/"} } 

Does anyone know a fix or how I can do this?

Answer 1

Every package should be responsible for autoloading itself, what are you trying to achieve with autoloading classes that are out of the package you define?

One workaround if it's for your application itself is to add a namespace to the loader instance, something like this:

<?php  $loader = require 'vendor/autoload.php'; $loader->add('AppName', __DIR__.'/../src/'); 

Answer 2

The composer documentation states that:

After adding the autoload field, you have to re-run install to re-generate the vendor/autoload.php file.

Assuming your "src" dir resides at the same level as "vendor" dir:

• src
  • AppName
• vendor
• composer.json

the following config is absolutely correct:

{     "autoload": {         "psr-0": {"AppName": "src/"}     } } 

but you must re-update/install dependencies to make it work for you, i.e. run:

php composer.phar update 

This command will get the latest versions of the dependencies and update the file "vendor/composer/autoload_namespaces.php" to match your configuration.

Also as noted by @Dom, you can use composer dump-autoload to update the autoloader without having to go through an update.
