Different Template per Firewall
You're using two-factor authentication on multiple firewalls and you need to render the form differently for each firewall. Here's a basic solution for you:
Create a new form renderer class like this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38
<?php
namespace Acme\Demo;
use Scheb\TwoFactorBundle\Security\TwoFactor\Provider\TwoFactorFormRendererInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Security\Http\FirewallMapInterface;
use Twig\Environment;
class CustomFormRenderer implements TwoFactorFormRendererInterface
{
private $twigEnvironment;
private $firewallMap;
private $templates; // Map of [firewall name => template path]
public function __construct(
Environment $twigRenderer,
FirewallMapInterface $firewallMap,
array $templates
) {
$this->twigEnvironment = $twigRenderer;
$this->firewallMap = $firewallMap;
$this->templates = $templates;
}
public function renderForm(Request $request, array $templateVars): Response
{
$firewallName = $this->firewallMap->getFirewallConfig($request)->getName();
$template = $this->templates[$firewallName];
$content = $this->twigEnvironment->render($template, $templateVars);
$response = new Response();
$response->setContent($content);
return $response;
}
}Register it as a service:
1 2 3 4 5 6 7 8 9
# config/services.yaml
services:
acme.custom_form_renderer:
class: Acme\Demo\CustomFormRenderer
arguments:
- '@twig'
- '@security.firewall.map'
# This is a map of firewall name to template path
- { main: 'security/2fa_google.html.twig', admin: 'admin/security/2fa_google.html.twig' } ]Configure the new service as the form renderer:
1 2 3 4 5
# config/packages/scheb_2fa.yaml
scheb_two_factor:
google: # Or "totp" or "email", depending on the two-factor provider you're using
enabled: true
form_renderer: acme.custom_form_renderer
