Autoload module class in Prestashop - prestashop

Question

I've created a module that has an override for the FrontControllerCore class to add additional Smarty variables.
The issue I'm running into is trying to autoload a class that is referenced in the controller that is in my module. The class isn't being loaded and I don't know how to add it to the autoloader.

Answer 1

When you install the module the FrontController.php file should be located in:
override\classes\controller\
so from the FrontController.php you can "include" manually that file like:
require_once(dirname(__FILE__).'/../../../modules/servicecharges/classes/ServiceCharge.php');
There's no autoload for such includes.

Answer 2

Also you can use this free tiny module that override Prestashop autoload. After that all your module custom class will be autoloaded.
Exemple path: /modules/my_module/libs/classes/MyClass.php

I've been able to solve a similar problem, with Composer's autoload. Way to require an autoload in one file on a Prestashop module?
Instead of overriding a controller (leading to conflicts with other plugins or installations of Prestashop already using the same overrides) you could invoke the hook moduleRoutes.
This way, you could call your autlooader always before the controllers:
<?php
public function hookModuleRoutes() {
require_once __DIR__.'/vendor/autoload.php'; // And the autoload here to make our Composer classes available everywhere!
}
