How do I get my composer package autoloaded properly? - php

Question

I have created a package to separate out business logic into easier to distribute modules. The composer file looks like this:
{
"name": "aggiq/johnny-cash",
"description": "A collection of controllers, models, migrations, and tests for a phonebanking backend.",
"license": "MIT",
"authors": [ ... ],
"require": {
"illuminate/database": ">=5.5"
},
"require-dev": {
"fzaninotto/faker": "~1.4"
},
"autoload": {
"psr-4": {
"Johnny\\Phonebanking\\": "src/"
}
}
}
And our source files are indeed in src/:
src/Controllers/PhonebankController.php
src/Models/Phonebank.php
...
I saved and pushed this to our gitlab repo, and then included it as a dependency in a test project:
{
...,
"repositories": [{
"type": "package",
"package": {
"name": "aggiq/johnny-cash",
"version": "0.1",
"type": "package",
"source": {
"url": "gitlab url",
"type": "git",
"reference": "dev"
}
}
}],
"require": {
"aggiq/johnny-cash": "*",
},
...
}
And when I do composer update, it successfully grabs the project and downloads it into the vendor folder:
vendor/aggiq/johnny-cash/Controllers/PhonebankController.php
...
However, when I look in the test project's autoload_psr4.php, it's not there. Is there a step I missed?
Edit: updates the directories to have capital letters to match the namespaces, and here is the generated PSR4 php file:
<?php
// autoload_psr4.php #generated by Composer
$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($vendorDir);
return array(
);

Answer 1

You have registered autoloading at your package's composer.json correctly:
"autoload": {
"psr-4": {
"Johnny\\Phonebanking\\": "src/"
}
}
This means, any class in Johnny\Phonebanking namespace will be in src directory. E.g.:
Johnny\Phonebanking\SomeClass => src/SomeClass.php
Johnny\Phonebanking\SomeNamespace\AnotherClass => src/SomeNamespace\AnotherClass.php
As you can see, it has to respect CapitalLetters.
Saying that, you should correct first letters of your directories, from:
src/controllers/PhonebankController.php
src/models/Phonebank.php
to
src/Controllers/PhonebankController.php
src/Models/Phonebank.php

I have solved it. We needed to do two things.
The repository type specified in the parent pacakge should be vcs not package since we are loading from a git server:
"repositories": [{
"type": "vcs",
"url": "git#xxx.git"
}]
The package type in the child package should be library:
"type": "library"
Once those two changes were made, composer update installed not only the child package but also its dependencies, proving it is being recognized by composer.
