Question

在这里，我的数据库中有一个保险表，用于存储医生可以关联的保险（带有其名称和徽标）。现在，医生可以在其医生空间中选择一个，两个或不选择任何保险。但是，我有一个问题，当医生不隶属于任何保险时，我想选择一个默认值，表明该医生还没有保险，但是我选择的不是保险的任何事情都不会生效。

控制器

String[] projection = {DataContract.DataEntry._ID,
        DataContract.DataEntry.COLUMN_PROJECT_NAME,
        DataContract.DataEntry.COLUMN_HEAD,
        DataContract.DataEntry.COLUMN_CITY,
        DataContract.DataEntry.COLUMN_COST};

树枝

   public function editAction(Request $request)
{
    $user = $this->getUser();
    if ($user === null) {
        throw new NotFoundHttpException('Utilisateur Inexistant');
    }

    $em = $this->getDoctrine()->getManager();
    $repo = $em->getRepository('DoctixMedecinBundle:Medecin');
    $specialiteRepo = $em->getRepository('DoctixAdminBundle:Specialite');

      $cliniqueRepo = $em->getRepository('DoctixAdminBundle:Clinique');

    $assuranceRepo = $em->getRepository('DoctixMedecinBundle:Assurance');

    $object = $assuranceRepo->findOneBy(array('id' => $request->get('assurance')));
  $medecin = $repo->findOneBy(array(
        'user' => $user,
    ));

    if ($request->isMethod('POST')) {

        if ( ($pass = $request->get('pass')) != ''){
            $medecin->getUser()->setSalt('');
            $factory = $this->get('security.encoder_factory');
            $encoder = $factory->getEncoder($medecin->getUser());
            $password_encoder = $encoder->encodePassword($pass, $medecin->getUser()->getSalt());
            $medecin->getUser()->setPassword($password_encoder);
        }

        $medecin->setSpecialite($specialiteRepo->find($request->get('specialite')));
         $medecin->setClinique($cliniqueRepo->find($request->get('clinique')));
        $medecin->getUser()->setAdresse($request->get('adresse'));
        $medecin->getUser()->setNumTel($request->get('telephone'));
        $medecin->setQuartier($request->get('quartier'));
        $medecin->setNumOrdre($request->get('numordre'));

        if ($object) {
            $medecin->addAssurance($object);
        } 
     $em->persist($medecin);

        $em->flush();

        // redirection avec le status http 301 ::)))))
        $url = $this->generateUrl('medecin_parametre');
        return $this->redirect($url, 301);

    } else {
        return $this->render('DoctixMedecinBundle:Medecin:editProfile.html.twig', array(
            'medecin' => $medecin,
            'specialites' => $specialiteRepo->findAll(),
            'cliniques' => $cliniqueRepo->findAll(),
            'assurances' => $assuranceRepo->findAll()
        ));
    }
}

树枝视图，将显示或不显示医生所属的保险

  <div class = "col-md-6">

                                    <div class="form-group">
                                        <label for="assurance" class="control-label">Assurance </label>

                                        <select id="assurance" class="form-control" placeholder="Assurance" name="assurance" multiple >
                                            <option value="Pas d Assurance" selected="Pas encore">Pas d'Assurance</option>

                                            {% for assurance in assurances %}
                                                <option value="{{ assurance.id }}" 
                                                {% for it in medecin.assurance %}
                                                {{ it.id == assurance.id ? 'selected' : '' }}
                                                {% endfor %} >{{ assurance.nom|upper }}</option>                                            
                                            {% endfor %}
                                        </select>

                                    </div>

                                </div>

  <div class="row">
                <div class="col-md-offset-3 col-md-3">
                    <input type="submit" class="btn_1 btn-success medium" form="editProfil" value="Valider">
                    <a href="{{ path('medecin_parametre') }}" class=" btn_1 btn-danger medium">Annuler </a>
                </div>
            </div>

现在当医生没有保险时，如何显示一段说“没有保险”的文字？谢谢。

要检查医学药物是否有任何保证，您必须检查数组{% if medecin.assurance is empty %} {# This medecin has no assurances, act accordingly #} {% else %} {# Display medecin's assurances #} {% for item in medecin.assurance %} {# Display each assurance #} {% endfor %} {% endif %}是否为空

类似这样的东西：

在symfony和html中的select中选择默认选择字段
