Symfony 6 Check if File Exists in Public Folder

When you are working with Symfony 6 and you want to delete a post that has an image, you must remove the file too, thus the uploads folder is not full of unused images.
Check before delete
Let's assume that we want to delete a post with an image, all we need to do is to use the Filesystem class that provides the method exists, the method takes the path as a parameter and checks if the file exists then the file is deleted if not we delete only the post.
<?php
namespace App\Controller;
use App\Entity\Product;
use App\Repository\ProductRepository;
use Doctrine\Persistence\ManagerRegistry;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Filesystem\Filesystem;
class ProductController extends AbstractController
{
private $productRepository;
private $entityManager;
public function __construct(
ProductRepository $productRepository,
ManagerRegistry $doctrine)
{
$this->productRepository = $productRepository;
$this->entityManager = $doctrine->getManager();
}
#[Route('/product/delete/{id}', name: 'product_delete')]
public function delete(Product $product): Response
{
$filesystem = new Filesystem();
$imagePath = './uploads/'.$product->getImage();
//check if file exists in public folder
if($filesystem->exists($imagePath)){
$filesystem->remove($imagePath);
}
// tell Doctrine you want to (eventually) save the Product (no queries yet)
$this->entityManager->remove($product);
// actually executes the queries (i.e. the INSERT query)
$this->entityManager->flush();
$this->addFlash(
'success',
'Your product was removed'
);
return $this->redirectToRoute('product_list');
}
}
