To load configuration after login in Symfony, you can use the kernel.request event listener to modify the loaded configuration.


First, create a new event listener class by running the following command:

1
$ php bin/console make:listener


Then, follow the below steps:

  1. Choose the event you want to listen to: Select kernel.request from the options presented.
  2. Choose the class that should be associated with the event: Specify the listener class name, e.g., ConfigLoaderListener.


This will generate a new file in the src/EventListener directory, like src/EventListener/ConfigLoaderListener.php.


Open the created file (ConfigLoaderListener.php) and modify the onKernelRequest method as follows:

use SymfonyComponentHttpKernelEventRequestEvent;
use SymfonyComponentHttpKernelKernelInterface;

class ConfigLoaderListener
{
    private $kernel;

    public function __construct(KernelInterface $kernel)
    {
        $this->kernel = $kernel;
    }

    public function onKernelRequest(RequestEvent $event)
    {
        // Check if the user is logged in
        if (!$event->getRequest()->attributes->get('_route') === 'app_login') {
            // Load the configuration for logged in users

            // Get the current loaded configuration
            $configuredBundles = $this->kernel->getContainer()->getParameter('kernel.bundles');

            // Add/modify configuration options as needed
            // Example: $configuredBundles['AppBundle'] = 'AppEntityUser';

            // Set the modified configuration
            $this->kernel->getContainer()->setParameter('kernel.bundles', $configuredBundles);
        }
    }
}


In the above example, the onKernelRequest method checks if the user is not on the login page (app_login route) and then modifies the loaded configuration as required. You can extend this logic to load additional configuration options.


Finally, register your event listener in the config/services.yaml file:

1

# config/services.yaml
services:
    AppEventListenerConfigLoaderListener:
        tags:
            - { name: kernel.event_listener, event: kernel.request }


Now, whenever a user logs in, the ConfigLoaderListener will be triggered, allowing you to modify the loaded configuration based on your needs.
