Anonymous users can leave their e-mail when posting a comment but how can I display this e-mail as a plain text value in the comment.html.twig?

  • By default, anonymous comments have no such "e-mail" field. Was this field added by you? – No Sssweat Dec 19 '17 at 10:14
  • If yes and you used the e-mail field type, then simply go to the comments manage display and for Format select plain text. – No Sssweat Dec 19 '17 at 10:23
  • You can enable anonymous users to leave their contact information in the comments field of a content type. – rroose Dec 19 '17 at 18:56
  • Where is that option located at? – No Sssweat Dec 19 '17 at 23:11

    If you have a fresh Drupal 8 standard install, go to: 'People > Permissions' and Allow anonymous users to 'Post comments' and 'Skip comment approval'. Then go to: 'Structure > Content Types > Article > Manage Fields' and edit the 'Comments' field. Go to 'Anonymous commenting' and select 'Anonymous posters may leave their contact information'. Click 'Save settings'. Now when you go post a comment as an anonymous user you can leave your e-mail. – rroose Dec 20 '17 at 8:18

You can print that e-mail value in plain text like this:

{{ content.comment_body['#object'].getAuthorEmail() }}

Now, this will print the e-mails of logged in users as well. If you don't want that, then you will need to add a conditional to check if their User ID is 0, which means they are anonymous.

{% if attributes.toArray()['data-comment-user-id'] == 0 %}

    {{ content.comment_body['#object'].getAuthorEmail() }}

{% endif %}
