I'm really struggling with this issue. Well I'm having a view, in this view a field configured as personalized text as a link. I want to open a popup form on click on the link. Here is what I did in the method called by the link:

 $response = new AjaxResponse();
  $title = 'Title for the Popup.';
  $form['#attached']['library'][] = 'core/drupal.dialog.ajax';
  $content = '<div class="test-popup-content">' . 'Content in HTML format' . '</div>';
  $options = array(
    'dialogClass' => 'popup-dialog-class',
    'width' => '75%',
  $modal = new OpenModalDialogCommand($title, $content, $options);
  return $response; 

But It's not working at all! Please help!


Your code is building an ajax response. This only works in ajax callbacks, nowhere else.

If you want to make a link modal, so that it will open in a popup, you have to set the class use-ajax and the attribute data-dialog-type. Like in this example from ConfigSync.php:

$links['view_diff'] = [
  'title' => $this->t('View differences'),
  'url' => Url::fromRoute($route_name, $route_options),
  'attributes' => [
    'class' => ['use-ajax'],
    'data-dialog-type' => 'modal',
    'data-dialog-options' => json_encode([
      'width' => 700,

For modal links to work you need to attach a library, see How to create modal windows (pop-ups)?

  • thank you for the answer, but where can I can configure the class and the attribute from a link view? – Asy Nov 23 '16 at 9:46
  • The simplest method would be to rewrite the field with the link markup including the class and attribute. – 4k4 Nov 23 '16 at 11:05
  • <a class='use-ajax' data-dialog-type='modal' data-accepts="application/vnd.drupal-dialog" data-dialog-options="{"width":500}" href='url> modal </a> but still don't work :( – Asy Nov 23 '16 at 22:23

    This works: <a class="use-ajax" data-dialog-type="modal" href="http://mysite/node/1">Modal link</a> – 4k4 Nov 24 '16 at 7:31
