I'm working on a D8 project. I have a webform with multiple fields and one of those is a taxonomy term. The taxonomy term consist of the title and a file upload field. The admin uploads a file in the taxonomy, and in the webform selects which file/s should be visible to the end user.

In order to display those files to the user I created a webform submission view where I get the specific field. The point is that the field might return multiple values (taxonomy terms) which are separated by comma.

How can I remove that comma? In D7 you could choose the separator in mulivalue field but now I can't find something similar.

EDIT: The last idea was to change the output in the template file. So in views-view-field.html.twig I try to replace the comma with space in the output of the field.

{% set output = output|replace({(',') : (' '),}) %}

What I get is the html of the view with a lot of debug informations but the view is not rendered as it should. I get something like <!-- THEME DEBUG --> <!-- THEME HOOK: 'webform_element_base_html' --> <!-- FILE NAME SUGGESTIONS: *

Any idea why?


Finally, I found the solution. I'm not sure if is the best, but it works.

function MY_THEME_preprocess_views_view_field(&$variables){
  $view = $variables['view'];

  if ($view->id() == 'VIEW_ID'){
    $output = str_replace(',', '', $variables['output']);
    $variables['output'] = \Drupal\views\Render\ViewsRenderPipelineMarkup::create($output);
  • This solution works but it wipes out all commas that are in the content of the field as well. – Achraf JEDAY Aug 16 '17 at 15:25
  • Yes because it replaces the commas. I couldn't find any other working option! – Ismini Aug 16 '17 at 15:32

You are seeing <!-- THEME DEBUG --> because Twig debug is enabled in either your sites/default/services.yml or sites/development.services.yml. You can disable Twig debug as follows:


    debug: false
  • Yes, I know, but the point is that in the block I still get printed the html as a string and not the files as I should. – Ismini Jul 3 '17 at 16:05

You can change or remove the separator from the view configuration of the field:
