Ändere Seite in Drupal 8

Question

Ich habe dieses Projekt zum Hinzufügen von inline troc Verwaltung mit Drupal 8.

Wenn ich einige Daten ändern möchte, habe ich einige Probleme.

Ich möchte die Standardseite verlassen, weil ich die Liste auf dieser Seite nicht erreichen kann.

Gibt es eine Möglichkeit, den Standardmodus zu umgehen?

Hier ist mein Platzhalter-Code:

namespace Drupal\ajout_troc\Form; 
use Drupal\Core\Form\FormBase; 
use Drupal\Core\Form\FormStateInterface; 
use Drupal\Component\Utility\UrlHelper; 
use Drupal\node\Entity\Node; 
use \Drupal\file\Entity\File; 

class ContributeForm extends FormBase { 

    public function getFormId() { 
     return 'ajout_troc_contribute_form'; 
    } 

    public function extractRubriqueOptions() { 
     $terms = \Drupal::service('entity_type.manager') 
      ->getStorage("taxonomy_term") 
      ->loadTree('rubrique', $parent = 0, $max_depth = NULL, $load_entities = FALSE); 
     $options = array(); 
     foreach($terms as $term) { 
      $options[$term->tid] = $term->name; 
     } 
     return $options; 
    } 
    public function buildForm(array $form, FormStateInterface $form_state) { 

     $form['rubrique'] = array(
      '#type' => 'select', 
      '#title' => t('Rubrique'), 
      '#options' => $this->extractRubriqueOptions(), 
      '#required' => TRUE, 
     ); 
     $form['titre'] = array(
      '#type' => 'textfield', 
      '#title' => t('Titre du bien'), 
      '#required' => TRUE,

     $form['description'] = array(

     $form['valeur'] = array(

     ); 
     $form['label'] = array(
      '#type' => 'label', 
      '#title' => t('Ce que vous souhaitez en échange'), 
     ); 
     $form['echange'] = array(
      '#type' => 'select', 
      '#title' => t('Sélectionnez les rubriques qui vous intéressent : '), 
      '#multiple' => true, 
      '#options' => $this->extractRubriqueOptions(), 
      '#required' => TRUE, 
     ); 
     $form['descriptionechange'] = array(
      '#type' => 'textarea', 
      '#title' => t('Décrivez ici ce que vous souhaitez en échange :'), 
     ); 

     $form['actions'] = array('#type' => 'actions'); 
     $form['actions']['submit'] = array(
      '#type' => 'submit', 
      '#value' => t('Enregistrer mon annonce'), 
      '#attributes' => array('class' => array('button', 'button--primary', 'js-form-submit', 'form-submit')) 
     ); 
     return $form; 
    } 

    public function validateForm(array &$form, FormStateInterface $form_state) { 

     if (strlen($form_state->getValue('telephone'))!=8) { 
      $form_state->setErrorByName('telephone', $this->t("Le numéro de téléphone doit contenir 8 chiffres.")); 
     } 
    } 


    public function submitForm(array &$form, FormStateInterface $form_state) 
    { 
     $user = \Drupal::currentUser(); 

     $fields = array(
      'type' => 'troc', 
      'title' => 'Annonce', 
      'status' => 0, 
      'created' => REQUEST_TIME, 
      'changed' => REQUEST_TIME, 
      'uid' => $user->id(), 
      'field_rubrique' => array(
       'target_id' => $form_state->getValue('rubrique')

     ); 
     $echanges = $form_state->getValue('echange'); 
     foreach ($echanges as $echange) { 
      $fields['field_echange'][] =array(
       'target_id' => $echange 
      ); 
     } 
     $photoFid = $form_state->getValue('photo'); 
     if(!empty($photoFid[0])) { 
      $photoFid = $photoFid[0]; 
      $photo = \Drupal\file\Entity\File::load($photoFid); 
      $photo->setPermanent(); 
      $photo->save(); 
      $fields['field_photo'] = array(
       'target_id' => $photoFid, 
      ); 
     } 
     $node = Node::create($fields); 
     $node->save(); 
    } 
} 

Für mehr Infos, hier ist Screenshot für die Schnittstelle. Ich möchte das "Rubrique" Feld eine Liste auswählen, weil ich einige Optionen habe und ich will die user frei fühlen und wählen Sie seine beste Option. Der Link unten ist der Screenshot.
