Access to user name in config file for Symfony - php

Question

I'm using FMElfinder in association with TinyMCE for managing the assets (images, pdf ...) of the users (managed with FOSUSerBundle)
I've seen that this tool can handle multiple root folder, but in my case, it isn't quite usable : i would like to have a root folder for each user.
In the configuration file app/config/config.yml, there is the root path(s) defined :
fm_elfinder:
instances:
default:
locale: %locale%
...
connector:
roots:
uploads:
driver: LocalFileSystem
path: uploads/data
I was thining about "simply" changing the path to something like :
path: uploads/data/{the_username}
where the username would be the username of the currently logged user
In a controller i can do
$user = $this->get('security.token_storage')->getToken()->getUser();
$username = $user->getUsername();
But i don't know if it's possible (and if so, how) to access specifically the username of the logged user into a config file
Thank you if you have any suggestion
=================[EDIT] ==========================================
I've use the override of configuration. I think i followed the steps, but i haven't managed to make it work :
1 - Create the class
use FM\ElfinderBundle\Model\ElFinderConfigurationProviderInterface;
use Symfony\Component\DependencyInjection\ContainerInterface;
class ElfinderConfigurator implements ElFinderConfigurationProviderInterface
{
protected $container;
protected $options;
/**
* #param ContainerInterface $container
*/
public function __construct($options, ContainerInterface $container)
{
$this->container = $container;
$this->storage = $container->get('security.token_storage');
$this->options = $options;
}
/**
* #param $instance
*
* #return array
*/
public function getConfiguration($instance)
{
//retrieve basepath
$basepath_abs = $this->container->get('kernel')->getRootDir()."/../web/uploads";
$basepath = "uploads/data";
//define path for user
$userid = $this->storage->getToken()->getUser()->getId();
$root = $basepath.'/'.$userid;
$this->options['instances']['default']['connector']['roots']['uploads']['path'] = $root.'/root';
$this->options['instances']['default']['connector']['roots']['uploads']['upload_max_size'] = '2M';
$option = [
'corsSupport' => false,
'roots' => $this->options['instances']['default']['connector']['roots'],
];
$root_abs = $basepath_abs.'/data/'.$userid;
//creates dir if not available
if (!is_dir($root_abs)) {
mkdir($root_abs.'/root', 0775, true);
}
return $option;
}
}
2 - Set my service :
myvendor.mybundle.elfinder_configurator:
class: Myvendor\Mybundle\Services\ElfinderConfigurator
arguments: ["%fm_elfinder%", "#service_container"]
3 - Call the service in app/config/config.yml
fm_elfinder:
configuration_provider: myvendor.mybundle.elfinder_configurator
...
It works partially : When i open the elfinde, the directory are correctly created if they don't exists. But there must be a path problem, and i'm not sure it's well overriden because :
- The thumbs are not displayed in elfinder
- When i add the image to the editor, i don't have the correct path of the image, i have :
//app_dev.php/efconnect?cmd=file&target=l1_Q2FwdHVyZSBkJ8OpY3JhbiBkZSAyMDE2LTAxLTI0IDE0OjM2OjI0LnBuZw
instead of the actual path of the image (if i don't use the override, the tool works and gives me this path)
../../../../uploads/data/1/root/img1.png
and no image is displayed.
Also, if i look in the js console for the
efconnect?cmd=open&target=&init=1&tree=1&_=1469377765664
I see that uplMaxSize is 200M,
in any case, there is no js error in the console

I think you are looking for a custom config provider:
https://github.com/helios-ag/FMElfinderBundle/blob/master/Resources/doc/advanced-configuration.md#custom-configuration-provider
You could then inject the token storage into the service and fetch the user from
like in any controller:
services:
my_elfinder_configurator:
class: Acme\DemoBundle\elFinder\UserAwareConfigurator
arguments: ["#token_storage", "%any_container_params%"]
