php - undefined data result ajax symfony
one text
Solution:
first check, if your $products
returns anything by e.g. dumping it: dump($products);
if yes, try to return a JsonResponse
use Symfony\Component\HttpFoundation\JsonResponse;
// encode your $products on the fly
$response = new JsonResponse($products);
// if the data to send is already encoded in JSON
$response = JsonResponse::fromJsonString('$jsonContent');
