Autoload with composer custom classes

Question

I'm new to composer to manage the loading of my custom classes. I'm trying to add some custom classes to the autoload but without success, I will get always a Class not found... error.

How I will setup correctly composer, where I should put the composer.json file with the psr-4 info about my custom class/classes?

Can anyone help me understand how it will work in this case? Here is my class code snippet, I'm using some composer packages so I need to autoload them. This file is placed in it's own directory. th structure looks like this: project_root\assets\library\MyClassFolder

<?php
namespace MyNamespace;

require_once __DIR__.'/vendor/autoload.php';

use \Foo\Bar;

class MyClass {
 ...
}

?>

This is the code where the class need to be loaded. This file is located inside my project root folder and it's causing the error:

<?php

require_once __DIR__.'/vendor/autoload.php';

use \MyNamespace\MyClass;

if( isset($_POST['do_action']) ){
MyClass::init();
}
?>

This is the composer.json file that is in the project root:

{
    "require": {
        "gabordemooij/redbean": "^5.3"
    },
    "autoload": {
      "psr-4": {
        "MyNamespace\\": "assets/library/"
      }
    }
}

Can you share the full and exact error message, and the exact file names? If your namespace is called MyNamespace, then your folder should not be named MyClassFolder — Nico Haase
@NicoHaase The folder name is the same of the namespace, I've used MyClass folder to be more clear in the question. The error i get is /controller.php - Uncaught Error: Class 'MyNamespace\MyClass' not found — Oshione

I've found a fix, I was made a mistake inside the composer.json file. I was not pointing the namespace to the classes directory. This is why I've got a Class not found... error.

the composer file now look like this:

{
    "require": {
        "gabordemooij/redbean": "^5.3"
    },
    "autoload": {
      "psr-4": {
        "MyNamespace\\": "assets/library/MyClassFolder/"
      }
    }
}

I also needed to change the require_once inside the custom classes files to point to the vendor path where reside the autoload file.

Instead of require_once __DIR__.'/vendor/autoload.php'

Now I've

require_once dirname(__DIR__, 3).'/vendor/autoload.php' This because the
