Custom file upload on Symfony admin pages (1.7.6)

[direwald]

Hello, continuation from my previous topic, I'm now stuck on using the Symphony framework to get my custom file uploaded on the server. Using a module, I'm using the formBuilder to create the file input on category page. I'm not quite sure how to proceed from here though. I tried to follow this (https://symfony.com/doc/3.4/controller/upload_file.html) Symfony guide, but couldn't quite apply it to the Prestashop system.

I think I should be using the UploadedFile component in my module to handle this, but I've no experience with Symfony and I'm not sure how to properly implement it into my module.

Below is my module file, any help would be greatly appreciated

<?php
if (!defined('_PS_VERSION_')) {
    exit;

use Symfony\Component\Validator\Constraints\File;

It works great, but how do you write data to the frontend? Thank you
