How do I check if object was found in a Doctrine2 repository?
EntityRepository::find() method (which you use) returns an object, or null if the object couldn't be found in the database. All of the following conditions are valid:
if ($entity) {}if (null !== $entity) {}if ($entity instanceof Representative) {}Choose one that suits your coding standards the best, and use it consistently.
If you don't need to create a new object if it's not found, better throw an exception and handle it appropriately.
How about this:
$product = $this->getDoctrine() ->getRepository('AppBundle:Product') ->find($id); if (!$product) { throw $this->createNotFoundException( 'No product found for id '.$id );Source: click me
