Symfony 2 Formular mit mehreren Tabelle wählen Sie Typ

Question

Ich bin Anfänger symfony Entwickler. Ich habe großes Problem mit Form ich mag Daten auf meine Tabellennamen Kampagnen speichern, die wie folgt aussehen:

contacts_groups: 
id, user_id, name, description, created 

für Empfänger-System

Campaigns: 
id, user_id, recipients, message, sender, type, created 

und die nächsten

Ich habe 2 Tabellen in der Basis

und

contacts: 
id, user_id, group_id, email, city, created. 

lassen jetzt ‚S gehen davon aus, dass meine folgenden Tabellen Datensätze:

contacts_groups: 
     id, user_id, name, description, created 
     1, 1, Test Group, Newest recipients, 2016-20-02 14:24:00 
     2, 1, Awesome Group, Pro players, 2016-10-02 11:22:41 
    contacts: 
     id, user_id, group_id, email, city, created 
     1, 1 , 1, exmple@email.com, New York, 2016-12-12 12:12:12 
     2, 1 , 1, test@emailer.com, New York, 2016-12-12 12:12:12 
     3, 1 , 2, proplayer@games.com, New York, 2016-12-12 12:12:12 

Jetzt i eine Form mit zwei Tabellen tun wollen zeichnet Beispiel:

TextField => text for sender name row 
ChoiceType => select with options with contacts_groups records 
ChoiceType => select with options with contacts where group_id == choosed contacts_groups record above. 

ich habe diesen Code:

class CampaignsType extends AbstractType{ 


public function buildForm(FormBuilderInterface $builder, array $options) { 
    $Campaigns = $options['data']; 
    $user  = $Campaigns->tmpusr; // variable transferred from the controller (logged user id) 

    $builder 
      ->add('sender', TextType::class, array(
      'trim'  => true, 
      'label' => 'Odbiorca', 
      'label_attr' => array('class' => 'col-sm-2 control-label'), 
      'attr' => array('class' => 'form-control', 'maxlength' => '11') 
       )) 
     ->add('recipients', EntityType::class, array(
      'label' => 'Grupa odbiorców', 
      'label_attr' => array('class' => 'col-sm-2 control-label'), 
      'attr' => array('class' => 'form-control'), 
      'class' => 'MyAppPanelBundle:ContactsGroups', 
      'query_builder' => function (\Doctrine\ORM\EntityRepository $er) use ($user) { 
       return $er->createQueryBuilder('u') 
        ->select('u') 
        ->add('where', 'u.user_id = ' . $user) 
        ->orderBy('u.id', 'DESC'); 

      }, 
      'choice_value' => 'id', 
      'choice_label' => 'name', 
       ));  
} 

Weiß jemand, wie man das nächste Feld mit Kontakten aus der Datenbank hinzufügt, wobei group_id dasselbe ist wie die ID der ausgewählten Gruppe?

Danke an alle.

Answer 1

Ja von Ajax:

• Ad dies in Ihrem CampaignsType:

  ->add('contact', ChoiceType::class, array(
       'required' => true, 
       'placeholder' => 'choose contact' 
      )) 
  

• Ihrer Ansicht:

     <div class="form-group"> 
          {{ form_label(form.contact, label|default(null), { 'label_attr': { 'class': 'font-secondary' } }) }} 
          {{ form_widget(form.contact, {'attr' : {'class' : 'form-control'}})}} 
          {{ form_errors(form.contact) }} 
         </div> 
  

• in Ihrem Controller:

`

/** 
* @Route("/select/contact", name="_select_contact") 
*/ 
public function contactsAction(Request $request) { 
    $group_id = $request->request->get('group_id'); 
    $em = $this->getDoctrine()->getManager(); 
    $contacts = $em->getRepository('AppBundle:Contact')->getContacts($group_id); 
    return new JsonResponse($contacts); 
} 

• in Ihrer js-Datei:

    $("#campaigns_group").change(function() { 
        var data = { 
         group_id: $(this).val() 
        }; 
        //$('form').spin(); 
        $.ajax({ 
         type: 'post', 
         url: Routing.generate('_select_contact'), 
         data: data 
        }).done(function (response) { 
         var $contacts_selector = $('#campaigns_contact'), 
          contacts = response.contact; 
         $contacts_selector.html('<option>choise contact</option>'); 
         for (var i = 0, total = contacts.length; i < total; i++) { 
          $contacts_selector.append('<option value="' + contacts[i].id + '">' + contacts[i].email + '</option>'); 
         } 
  
        }).fail(function() { 
         alert("error"); 
        }).always(function() { 
         //$('form').find('.spinner').hide() 
        }); 
       }); 
  

Erstellen Sie einfach das getContacts() in dem in Kontakt Repository und ajust JavaScript Ihre Bedürfnisse zu füllen.

Hoffe diese Hilfe!
