Symfony2 Wahl Formulardaten von ORM

Question

Lassen Sie sich diese Form:

class ScanType extends AbstractType 
{ 
     public function buildForm(FormBuilderInterface $builder, array $options) 
     { 
       $builder->add('scantarget', 'entity', array(
             'class' => 'AppBundle:Website', 
             'property' => 'url' 
             )); 
     } 


     public function getDefaultOptions(array $options) { 
     return array(
      'data_class' => 'AppBundle\Entity\Website', 
     ); 
    } 


} 

Du möchtest mit nur URLs für die jeweilige Benutzer-ID

In der Steuerung füllen:

  /** 
     * @Route("/verification-ok", name="verifyurlok") 
     */ 
     public function verifyurlActionOK(Request $request) 
     { 
       $user = $this->getUser(); 



       if($user) 
       { 
         $userid=$user->getId(); 

         $websites = $this->getDoctrine()->getRepository('AppBundle:Website')->findByUser($userid); 


         $form = $this->createForm(ScanType::class, $websites); 

jedoch die $ Websites werden nicht ordnungsgemäß an FormBuilder übergeben und in meinem Select-Feld werden alle Einträge angezeigt :(Alle möglichen Werte für Website-Entität.

Wie zeigt man nur übermittelte $ -Webseiten im Formular an (Auswahlfeld)? Also nur Webseiten für eine bestimmte Benutzer-ID?

Danke,

Funktioniert !!!

Answer 1

Nun, Sie legen die Auswahl nicht fest. Versuchen Sie folgendes:

class ScanType extends AbstractType 
    {  
      private $websites; 


      public function buildForm(FormBuilderInterface $builder, array $options) 
      { 
       $this->websites = $options['trait_choices']; 

        $builder->add('scantarget', 'entity', array(
          'class' => 'AppBundle:Website', 
          'property' => 'url', 
          'choices' => $this->websites 
         )); 
      } 


      public function setDefaultOptions(array $options) { 
      return array(
       'data_class' => 'AppBundle\Entity\Website', 
       'trait_choices' => null, 
      ); 
     } 


    } 

Im Controller Durchlauf durch die Websites:

$form = $this->createForm(ScanType::class, $websites, array(
     'trait_choices' => $websites, 
    )); 

Answer 2

Ihre Form zeigt alle Website-Einträge, weil Sie nicht diese zu beschränken, wenn das Formular erstellen, in der Methode add() .

Sie sollten diesen Abschnitt fo Kochbuch lesen: http://symfony.com/doc/current/form/dynamic_form_modification.html#form-events-user-data
