I have a content type “Articles”, this is a multi-language site, by default the content is created in English, and then translated into Spanish. On new article in English, I set a title and a term for the “Category terms” field, this field is an “Entity Reference”, and I’m using “Entity Browser” to show terms from a view (they are a lot of terms), when I create a translation from English to Spanish I need to remove any term related to “Category terms” field. I have tried a couple of ways, but this is not working for this field.

Here is the hook code that I’m using.

<?php  use DrupalCoreFormFormStateInterface;  /**  * Implements hook_form_alter().  */ function mymodule_form_alter(&$form, FormStateInterface $form_state, $form_id) {    // Form state object double check.   if (is_object($form_state) && method_exists($form_state, 'getStorage')) {      $form_storage = $form_state->getStorage();      // Temporal condition to avoid unexpected results while developing     if ($form_id == 'node_articles_form') {        // Check if form is a translation.       if (isset($form_storage['content_translation'])) {          // Hard coded test to override title - This works.         $form['title']['widget'][0]['value']['#default_value'] = 'Forced title text translation';           // Hard coded test to override Meta Search Terms - This doesn't work. Is not applyed         $form['field_category_terms']['widget']['entity_browser']['#default_value'] = [];          // Removing completely the field - This is not a solution, only for test.         // unset($form['field_category_terms']);          // Removing data from "Callback Object"         $build_info = $form_state->getBuildInfo();         // Getting the entity         $entity = $build_info['callback_object']->getEntity();         // Removing terms from entity         $entity->field_category_terms = [];         // Setting the entity         $build_info['callback_object']->setEntity($entity);         // setting a modified callback object to the $form_state         $form_state->setBuildInfo($build_info);          // Removing target_id default value.         unset($form['field_category_terms']['widget']['target_id']['#default_value']);       }     }   } }
