Symfony2: spl_object_hash() expects parameter 1 to be object, string given in Doctrine

Question

I am trying to populate the database with the object User and Person by executing

persist and flush.

First of all, I am creating the Person object and persist and flush it:

$person->setFirstname($enquiry->getFirstname()); $person->setLastname($enquiry->getLastname()); $person->setLastname($enquiry->getLastname()); $person->setSex($enquiry->getSex()); $person->setEmail($enquiry->getEmail()); $person->setAddress1($enquiry->getAddress1()); $person->setAddress2($enquiry->getAddress2()); $person->setCity($enquiry->getCity()); $person->setZipcode($enquiry->getZipcode()); $country = $em->getRepository('SciForumVersion2Bundle:Country')->findOneById($enquiry->getCountry());   $person->setCountry($country);  $em->persist($person); $em->flush(); 

And then my User object:

$user->setEmail($enquiry->getEmail()); $user->setPassword($enquiry->getPassword()); $user->setPersonId($person->getId()); $user->setDegree($enquiry->getDegree()); $user->setSex($enquiry->getSex()); $user->setOrganization($enquiry->getOrganization()); $user->setTelephone($enquiry->getTelephone()); $user->setFax($enquiry->getFax()); $user->setWorkplace($enquiry->getWorkplace());   $user->setJobtype($enquiry->getJobtype()); $user->setResearchField($enquiry->getResearchField()); $user->setManageConference(0); $user->setIp( $IP); $user->setStatus( 0 ); $user->setDateRegistered( time() );  $em->persist($user); $em->flush(); 

But when trying to flush() the persist of the user object, I am getting the error:

Warning: spl_object_hash() expects parameter 1 to be object, string given in /home/milos/workspace/conference2.0/vendor/doctrine/lib/Doctrine/ORM/UnitOfWork.php line 1095  

And here is the entier LOG:

Answer 1

I have finally found the problem:

When creating the object user, instead of setting those fields

$user->setDegree(); $user->setWorkplace();   $user->setJobtype(); $user->setResearchField(); 

as objects (because of the OneToMany relation), I gived here only a string, from the form.

So, for those fields, the code would be:

$degree     = $em->getRepository('SciForumVersion2Bundle:Degree')->findOneById($enquiry->getDegree()); $workplace  = $em->getRepository('SciForumVersion2Bundle:Workplace')->findOneById($enquiry->getWorkplace()); $job_type   = $em->getRepository('SciForumVersion2Bundle:JobType')->findOneById($enquiry->getJobtype()); $research_field = $em->getRepository('SciForumVersion2Bundle:ResearchField')->findOneById($enquiry->getResearchField()); 

And then:

$user->setPerson($person); $user->setWorkplace($workplace);     $user->setJobtype($job_type); $user->setResearchField($research_field); 

So: Be careful when you are getting this kind of warnings, you probably have to check if you are populating your object in the right way.
