I'm trying to make the comment author name required with this code:
use Drupal\Core\Form\FormStateInterface; /** * Implements hook_form_FORM_ID_alter(). */ function MODULE_form_comment_comment_form_alter(array &$form, FormStateInterface $form_state, $form_id) { $form['name']['#required'] = true; } But I can't find the way to do so. How to make the comment author name required for anonymous users?
You can try:
if (\Drupal::currentUser()->isAnonymous()) { $form['author']['name']['#required'] = TRUE; } It is necessary because it is not right to check if user is authenticated by checking if the name field is prefilled.
We have to use \Drupal::currentUser() service in theme or module file (in controller you have to use Drupal\Core\Session\AccountProxy).
/** * Implements hook_form_FORM_ID_alter(). */ function MODULE_form_comment_comment_form_alter(array &$form, FormStateInterface $form_state, $form_id) { if (\Drupal::currentUser()->isAnonymous()) { $form['author']['name']['#required'] = TRUE; } else { $form['author']['name']['#required'] = FALSE; } } I found the answer:
Implementing the hook_form_FORM_ID_alter() hook you can use the comment form id (comment_comment_form) to alter the form.
The problem was that the field name is inside the author, so you need to use $form['author']['name']['#required'] = TRUE;
/** * Implements hook_form_FORM_ID_alter(). */ function MODULE_form_comment_comment_form_alter(array &$form, FormStateInterface $form_state, $form_id) { $form['author']['name']['#required'] = TRUE; }
