For context: in my template file node--some-node.html.twig i have a grid of items which have a custom comment form on them. The form creates a comment through an API. The form passes the ID of the grid item it is under to the API and the created comment then has a field_profile_id with the item's id in it. Now, in the template file I need to output JUST the comments that belong to that grid item.

When I write this into the template file: {{ content.field_comments }} i get the output of all the comments that belong to this node and underneath I get the comment form (which I don't need). Ideally I would like to do everything in the same template file, so I could do something like this: {% if entity.nid.value == content.field_comments.someComment.field_profile_id %} {# output the comment here #} {% endif %}

Here the entity.nid.value is the node id of the grid items I was talking about earlier.

EDIT: Theoretically what I need to do is:

  • Iterate through all possible comments for this node.
  • Check if comment has some ID value (that a grid item might have)
  • If the IDs match, print out the comment, if it doesn't skip it

You must add a file to your template called


Use the following code.

 * @file
 * Theme override for comment fields.
 * Available variables:
 * - attributes: HTML attributes for the containing element.
 * - label_hidden: Whether to show the field label or not.
 * - title_attributes: HTML attributes for the title.
 * - label: The label for the field.
 * - title_prefix: Additional output populated by modules, intended to be
 *   displayed in front of the main title tag that appears in the template.
 * - title_suffix: Additional title output populated by modules, intended to
 *   be displayed after the main title tag that appears in the template.
 * - comments: List of comments rendered through comment.html.twig.
 * - comment_form: The 'Add new comment' form.
 * - comment_display_mode: Is the comments are threaded.
 * - comment_type: The comment type bundle ID for the comment field.
 * - entity_type: The entity type to which the field belongs.
 * - field_name: The name of the field.
 * - field_type: The type of the field.
 * - label_display: The display settings for the label.
 * @see template_preprocess_field()
 * @see comment_preprocess_field()
  set classes = [
    'field--name-' ~ field_name|clean_class,
    'field--type-' ~ field_type|clean_class,
    'field--label-' ~ label_display,
  set title_classes = [
    label_display == 'visually_hidden' ? 'visually-hidden',
<section{{ attributes.addClass(classes) }}>
  {% if comments and not label_hidden %}
    {{ title_prefix }}
    <h2{{ title_attributes.addClass(title_classes) }}>{{ label }}</h2>
    {{ title_suffix }}
  {% endif %}

  {{ comments }}

  {% if comment_form %}
    <h2 class='title comment-form__title'>{{ 'Add new comment'|t }}</h2>
    {{ comment_form }}
  {% endif %}

  • Hello, I am not really sure how this would help. Vaguely speaking what I need to do is: iterate through comments and check if a comment has a certain ID value. If it does, print it, if it doesn't don't. I will update my question

So the node in question had a field field_comments, from which I was trying to access the comments. I found a different way of doing that - I created a MYMODULE_preprocess_template function, loaded all comments of the node in that function, created a variable "comments", where I stored the comment data I needed and passed it on to the twig template. Here's the code in MYMODULE_preprocess_template function:

$node = \Drupal::routeMatch()->getParameter('node');

$user_comments = [];
  $entity_manager = \Drupal::entityTypeManager();
    $storage = $entity_manager->getStorage('comment');
    $comment_field = $node->get('field_comments');
    $comments = $storage->loadThread($node, $comment_field->getFieldDefinition()->getName(),\Drupal\comment\CommentManagerInterface::COMMENT_MODE_FLAT);
    foreach($comments as $comment) {
  $user_comments[] = [
    'cid' => $comment->id(),
    'user_id' => $comment->get('field_prf')->value,
    'comment' => $comment->get('field_comment')->value,
    'alias' => $comment->get('field_alias')->value,
    'rating' => $comment->get('field_rating')->value

  } catch (\Drupal\Component\Plugin\Exception\InvalidPluginDefinitionException $e) {
  } catch (\Drupal\Component\Plugin\Exception\PluginNotFoundException $e) {
  $variables['user_comments'] = $user_comments;
