i want to display a taget_id values for user in node's field but i can't print them , this is what I have done in the hook :

 $node = \Drupal::routeMatch()->getParameter('node'); if ($node && $node->bundle() == 'MynodeType') { $members = $node->field_members->getValue(); $members_ids = []; $current_user = \Drupal::currentUser(); $user_id = \Drupal\user\Entity\User::load($current_user->id()); foreach ($members as $member){ $members_ids[] = $member['target_id']; echo $members_ids; // why this is not like (1,8,....)? }

  • Welcome to Drupal Stackoverflow. Are you using PHPStorm like editor with xDebug mode enabled? It helps a lot. By putting breakpoint & see what result you are getting. . Please try $member_ids = array_map(function ($member) { return $member['target_id']; }, $node->get('members')->getValue()); Commented Mar 6, 2020 at 8:48
  • or $members_ids = array_column($node->field_members->getValue(), 'target_id'); see drupal.stackexchange.com/a/207715/47547 Commented Mar 6, 2020 at 10:05

Looks like this one has to be solved this way

 $members = $node->field_members; foreach ($members as $member) { $members_ids[] = $member->getValue()['target_id']; }
