How to toggle Symfony's php-translation/symfony-bundle EditInPlace - symfony

Question

I followed this documentation for Edit In Place, and setup the Activator, and it works!
However, I will be using this on the production site and allowing access via a ROLE_TRANSLATOR Authorization. This is also working, but I don't want the web interface always "on"
How would I go about enabling it via some sort of link or toggle?
My thoughts, it would be simple to just add a URL parameter, like ?trans=yes and then in the activator;
return ($this->authorizationChecker->isGranted(['ROLE_TRANSLATOR']) && $_GET['trans'] == 'yes');
Obviously, $_GET would not work, I didn't even try.
How do I generate a link to simply reload THIS page with the extra URL parameter
How do I check for that parameter within the "Activator"
or, is there a better way?

Answer 1

The "proper" way to do this, as I have discovered more about "services" is to do the logic diectly in the RoleActivator.php file.
referencing documentation for How to Inject Variables into all Templates via Referencing Services I came up with the following solution;
src/Security/RoleActivator.php
<?php
namespace App\Security;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Security\Core\Authorization\AuthorizationCheckerInterface;
use Symfony\Component\Security\Core\Exception\AuthenticationCredentialsNotFoundException;
use Translation\Bundle\EditInPlace\ActivatorInterface;
use Symfony\Component\Translation\TranslatorInterface;
use Symfony\Component\HttpFoundation\RequestStack;
class RoleActivator implements ActivatorInterface
{
/**
* #var AuthorizationCheckerInterface
*/
private $authorizationChecker;
/**
* #var TranslatorInterface
*/
private $translate;
/**
* #var RequestStack
*/
private $request;
private $params;
private $path;
private $flag = null;
public function __construct(AuthorizationCheckerInterface $authorizationChecker, TranslatorInterface $translate, RequestStack $request)
{
$this->authorizationChecker = $authorizationChecker;
$this->translate = $translate;
$this->request = $request;
}
/**
* {#inheritdoc}
*/
public function checkRequest(Request $request = null)
{
if ($this->flag === null) { $this->setFlag($request); }
try {
return ($this->authorizationChecker->isGranted(['ROLE_TRANSLATOR']) && $this->flag);
} catch (AuthenticationCredentialsNotFoundException $e) {
return false;
}
}
public function getText()
{
if ($this->flag === null) { $this->setFlag(); }
return ($this->flag) ? 'linkText.translate.finished' : 'linkText.translate.start'; // Translation key's returned
}
public function getHref()
{
if ($this->flag === null) { $this->setFlag(); }
$params = $this->params;
if ($this->flag) {
unset($params['trans']);
} else {
$params['trans'] = 'do';
}
$queryString = '';
if (!empty($params)) {
$queryString = '?';
foreach ($params as $key => $value) {
$queryString.= $key.'='.$value.'&';
}
$queryString = rtrim($queryString, '&');
}
return $this->path.$queryString;
}
private function setFlag(Request $request = null)
{
if ($request === null) {
$request = $this->request->getCurrentRequest();
}
$this->flag = $request->query->has('trans');
$this->params = $request->query->all();
$this->path = $request->getPathInfo();
}
}
config\packages\twig.yaml
twig:
# ...
globals:
EditInPlace: '#EditInPlace_RoleActivator'
config\services.yaml
services:
# ...
EditInPlace_RoleActivator:
class: App\Security\RoleActivator
arguments: ["#security.authorization_checker"]
So What I added over and above the php-translation example is the getText and getHref methods and corresponding private variables being set in the checkRequest and read there after.
Now in my twig template (in the header) I just use
{% if is_granted('ROLE_TRANSLATOR') %}
{{ EditInPlace.Text }}
{% endif %}
Add the new keys to the translation files and your done. the trans=do query parameter is toggled on and off with each click of the link. You could even add toggling styles with a class name, just copy the getText method to something like getClass and return string a or b with the Ternary.
