Question

its my VisitorController Class

{
$em = $this->getDoctrine()->getManager();
$lvisitor = $em->getRepository('EMRSabaBundle:Personel')->findOneBy(array('status' => '1', 'lastv' => '1', 'zone' => $zone));
$id = $lvisitor->getId();
$lvisitor->setLastv(0);
$newvisitorid = $em->getRepository('EMRSabaBundle:Personel')->findNewVisitor($id);
$newvisitorid = $newvisitorid[0];
$newvisitor = $em->getRepository('EMRSabaBundle:Personel')->find($newvisitorid);
$newvisitor->setLastv(1);
$em->flush();
return $newvisitor;
}
public function defineZone($Customer)
{
$phone = substr($Customer,1);
switch ($phone)

use EMR\SabaBundle\Entity\Orders;
use EMR\SabaBundle\Entity\Visit;
use EMR\SabaBundle\Controller\VisitController;
class EntityListener {
public function postPersist(LifecycleEventArgs $args)
{
$orders = $args->getEntity();
$em = $args->getEntityManager();
if ($orders instanceof Orders){
if ($orders->getStatus() == 1){
$VC = new VisitController();
$zone = $VC->defineZone($orders->getCustomer()->getId());
$personel = $VC->chooseVisitor($zone);
$visit = new Visit();
$visit->setDate(new \DateTime());
$visit->setStatus(0);
$visit->setOrders($orders);
$visit->setPersonel($personel);
$em->persist($visit);
$em->flush();
}
}

http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/events.html#postupdate-postremove-postpersist
postUpdate, postRemove, postPersist
The three post events are called inside EntityManager#flush(). Changes
in here are not relevant to the persistence in the database, but you
can use these events to alter non-persistable items, like non-mapped
fields, logging or even associated classes that are directly mapped by
Doctrine.
Try prePersist event.
