symfony - Insert data from form to database -

what want next:

1. create simple form formbuilder

2. when form submitted result saved database particular user ( based on id )

in addition code controller:

public function helloaction(request $request, $id){//displaying individual results particular user//   // find username in view//    $em = $this->getdoctrine()->getmanager();         $query = $em->createquery('select b acmewebbundle:baza b b.id = :id' )         ->setparameter('id',$id);         $total = $query->getresult();    $baza = new baza ();      $em = $this->getdoctrine()->getmanager();         $em->persist($baza);         $form = $this->createformbuilder($baza)                      ->add ('rating','choice',array('label'=>'test44','choices'=>array(                         '1'=>'1',                         '2'=>'2',                         '3'=>'3',                         '4'=>'4'                         ),                      'expanded'=>true,                     'multiple'=>false                     ))                     ->getform();           if ($request->getmethod() == 'post') {             $form->bindrequest($request);              if ($form->isvalid()) {                 // perform action, such saving task database                 $em->flush();                  return new response('<h1>thanks feedback !!!!</h1>');              }           }   return $this->render('acmewebbundle:default:hello.html.twig',array('all'=>$total,'id'=>$id ,'form'=>$form->createview())); } } 

but creates new row in database, , add value rating column.moreover, id field,username , etc.. empty.

what want is, rating added colum rating, specific id.

in following example create form, data on post , persist fresh object or modified one, there no point in persisting empty object.

public function historialaction(request $request) { $form = $this->createformbuilder() ->add('phone', 'text', array('attr' => array('autofocus' => ''))) ->add('period', 'number', array('attr' => array('value' => '12'))) ->getform();  if ($request->ismethod('post')) {     $form->bind($request);      // data array "phone" , "period" keys     $data = $form->getdata();      $em = $this->getdoctrine()->getmanager();      $contract = $em->getrepository('frontbundle:contract')->getcontractbyphone($data["phone"]);     $contract->setowner("john doe");     $contract->setphone($data["phone"]);      // or $contract = new contract("john doe", $data["phone"], $data["period"]);       $em->persist($contract); // set/modify properties persist }
