Question

我试图将CSS类添加到Drupal中的特定消息中，该消息在订阅mailchimp列表时成功输出，这是提交功能的代码：

public function submitForm(array &$form, FormStateInterface $form_state) {
global $base_url;

$list_details = mailchimp_get_lists($this->signup->mc_lists);

$subscribe_lists = array();

// Filter out blank fields so we don't erase values on the Mailchimp side.
$mergevars = array_filter($form_state->getValue('mergevars'));

$email = $mergevars['EMAIL'];

$mailchimp_lists = $form_state->getValue('mailchimp_lists');

// If we only have one list we won't have checkbox values to investigate.
if (count(array_filter($this->signup->mc_lists)) == 1) {
  $subscribe_lists[0] = array(
    'subscribe' => reset($this->signup->mc_lists),
    'interest_groups' => isset($mailchimp_lists['interest_groups']) ? $mailchimp_lists['interest_groups'] : NULL,
  );
}
else {
  // We can look at the checkbox values now.
  foreach ($mailchimp_lists as $list) {
    if ($list['subscribe']) {
      $subscribe_lists[] = $list;
    }
  }
}

$successes = array();

// Loop through the selected lists and try to subscribe.
foreach ($subscribe_lists as $list_choices) {
  $list_id = $list_choices['subscribe'];

  $interests = isset($list_choices['interest_groups']) ? $list_choices['interest_groups'] : array();
  if (isset($this->signup->settings['safe_interest_groups']) && $this->signup->settings['safe_interest_groups']) {
    $current_status = mailchimp_get_memberinfo($list_id, $email);
    if (isset($current_status->interests)) {
      $current_interests = array();
      foreach ($current_status->interests as $id => $selected) {
        if ($selected) {
          $current_interests[$id] = $id;
        }
      }
      $interests[] = $current_interests;
    }
  }
  $result = mailchimp_subscribe($list_id, $email, $mergevars, $interests, $this->signup->settings['doublein']);

  if (empty($result)) {
    drupal_set_message(t('There was a problem with your newsletter signup to %list.', array(
      '%list' => $list_details[$list_id]->name,
    )), 'warning');
  }
  else {
    $successes[] = $list_details[$list_id]->name;
  }
}

if (count($successes) && strlen($this->signup->settings['confirmation_message'])) {
  drupal_set_message($this->signup->settings['confirmation_message'], 'status');
}

$destination = $this->signup->settings['destination'];
if (empty($destination)) {
  $destination_url = Url::fromRoute('<current>');
}
else {
  $destination_url = Url::fromUri($base_url . '/' . $this->signup->settings['destination']);
}

$form_state->setRedirectUrl($destination_url);

}

我对更改此部分特别感兴趣：

if (count($successes) && strlen($this->signup->settings['confirmation_message'])) {
  drupal_set_message($this->signup->settings['confirmation_message'], 'status');
}

我想添加一个仅针对此确认消息而非所有消息输出的类。我已经尝试了几件事：

根据一些相关的问答，我尝试编辑上面的“状态”部分以在其中添加一个类：“状态conf”或“状态，conf”，这两项都不起作用，唯一接受的值是“状态”，“警告”和“错误”，其他值不会转换。
我也尝试过：

if（count（$ successes）&& strlen（$ this-> signup-> settings ['confirmation_message']））{ drupal_set_message（''。$ this-> signup-> settings ['confirmation_message']。''，'状态'）;

此选项不添加标记，而只是将其输出为字符串：

"<div class="conf">Our confirmation message</div>"

有什么建议吗？

树枝模板用于输出html消息。
为什么documentation建议'type'参数只有3个选项，我不知道，但这是错误的。状态消息就像其他任何可输出的（是一个单词？）一样。

添加自己的课程，例如import $ from "jquery"; let newobject = $.extend(true, {}, object);确实有效，但该类（使用经典主题模板时）将为drupal_set_message('Our confirmation message', 'conf');。

对于“经典”主题，消息模板位于“ core / themes / classy / templates / misc / status-messages.html.twig”，如下所示：

messages--conf

要覆盖它，只需将自己的“ status-messages.html.twig”添加到主题（MY_THEME / templates / misc / status-messages.html.twig）并根据需要进行更改。

向drupal_set_message添加CSS类
