I have a view (“Tasks”) that pulls in Task nodes, complete with sorting and filtering. Each Task can have multiple nodes attached via the “Related Articles” field (field_related_articles). I am trying to loop through each node (which can be a Video, Document, Article, etc.) and assign each link a class name depending on the type.
For example, a “Document” node attached to a Task would display a hyperlink with the document class. Video nodes will be video, and so on.
Here is my preprocess that is targeting the specific field:
function mytheme_preprocess_field__node__field_related_articles(&$variables) { $items = $variables['items']; foreach ($items as $index => $item) { $content_type = $item['content']['#options']['entity']->type->entity->label(); $class_name = slugify($content_type); // custom function $variables['items'][$index]['attributes']['class'] = [$class_name]; } } When I inspect the $variables array, I see the following, which looks okay to me (but I can’t be sure):
As you can see, the attributes object now has a class value for each items value (I have two). However, in the HTML, the classes do not show up:
Is there something I’m doing wrong?
