Issue
I would like to clear the website cache of my frontend whenever I make an update of a page in the backend.
This is my approach:
use FOS\HttpCacheBundle\CacheManager;
class ProjectController extends AbstractRestController
{
private CacheManager $cacheManager;
public function __construct(
CacheManager $cacheManager
) {
$this->cacheManager = $cacheManager;
parent::__construct($viewHandler, $tokenStorage);
}
protected function mapDataToEntity(array $data, Project $entity): void{
$entity->setName($data['name']);
$this->cacheManager->invalidatePath($path, $headers);
}
}
I get the error message:
Warning: Undefined variable $path
because I am not really sure why I need to create a variable "path". I would like to clear the cache of the whole website. Is this possible this way?
Solution
You can use this method in your controller, but I am not sure this will be a good idea to clear the cache in your controller every time you are in your /url
.
<php
private function celearCache(KernelInterface $kernel): void
{
$application = new Application($kernel);
$application->setAutoExit(false);
$env = $kernel->getEnvironment();
$input = new ArrayInput([
'command' => 'cache:clear',
'--env' => $env
]);
// You can use NullOutput() if you don't need the output
$output = new BufferedOutput();
$application->run($input, $output);
}
For more details about using commands in controllers see the official documentation.
