如何从表单添加 Commerce Wishlist 共享邮件模板变量？

问题描述

我正在尝试将 2 个额外的表单字段添加到愿望清单共享表单中，用户输入将在电子邮件中呈现。我已经能够将字段添加到表单中，但我不确定如何在电子邮件树枝模板中添加用户的输入。

这是我更新 form() 函数的方式：

  public function form(array $form,FormStateInterface $form_state) {
    $form['#tree'] = TRUE;
    $form['#attached']['library'][] = 'core/drupal.dialog.ajax';
    // Workaround for core bug #2897377.
    $form['#id'] = Html::getId($form_state->getBuildInfo()['form_id']);

    $form['to'] = [
      '#type' => 'email','#title' => $this->t('Recipient Email'),'#required' => TRUE,];

// COMBAK my edit

    $form['sender_name'] = [
      '#type' => 'textfield','#title' => $this->t('Your Name'),'#required' => FALSE,];

    $form['sender_message'] = [
      '#type' => 'textarea','#title' => $this->t('Your Message'),];

// COMBAK eo my edit

    return $form;
  }

  /**
   * {@inheritdoc}
   */
  protected function actions(array $form,FormStateInterface $form_state) {
    $actions['submit'] = [
      '#type' => 'submit','#value' => $this->t('Send email'),'#submit' => ['::submitForm'],];
    if ($this->isAjax()) {
      $actions['submit']['#ajax']['callback'] = '::ajaxSubmit';
    }

    return $actions;
  }

  /**
   * {@inheritdoc}
   */
  public function submitForm(array &$form,FormStateInterface $form_state) {
    /** @var \Drupal\commerce_wishlist\Entity\WishlistInterface $wishlist */
    $wishlist = $this->entity;
    $to = $form_state->getValue('to');

    // COMBAK: my added vars
    $sender_name = $form_state->getValue('sender_name');
    $sender_message = $form_state->getValue('sender_message');

    $this->wishlistShareMail->send($wishlist,$to,$sender_name,$sender_message);

    $this->messenger()->addStatus($this->t('Shared the wishlist to @recipient.',[
      '@recipient' => $to,]));
    $form_state->setRedirectUrl($wishlist->toUrl('user-form'));
  }

这是调用我更新过的mailHandler的函数：

public function send(WishlistInterface $wishlist,$sender_message) {
    $owner = $wishlist->getowner();

    $subject = $this->t('Check out my @site-name wishlist',[
      '@site-name' => $this->configFactory->get('system.site')->get('name'),]);
    $body = [
      '#theme' => 'commerce_wishlist_share_mail','#wishlist_entity' => $wishlist,// COMBAK: my added vars
      '#sender_name' => $sender_name,'#sender_message' => $sender_message,];
    $params = [
      'id' => 'wishlist_share','from' => $owner->getEmail(),'wishlist' => $wishlist,];

    return $this->mailHandler->sendMail($to,$subject,$body,$params);
  }

这是商业愿望清单模块提供的预处理功能：

function template_preprocess_commerce_wishlist_share_mail(array &$variables) {
  /** @var Drupal\commerce_wishlist\Entity\WishlistInterface $wishlist */
  $wishlist = $variables['wishlist_entity'];
  $wishlist_url = $wishlist->toUrl('canonical',['absolute' => TRUE]);

  $variables['wishlist_url'] = $wishlist_url->toString();

  // COMBAK: my added vars
  //$sender_name = $variables['sender_name'];
}

最后是电子邮件本身的树枝模板：

{#
/**
 * @file
 * Template for the wishlist share email.
 *
 * Available variables:
 * - wishlist_entity: The wishlist entity.
 * - wishlist_url: The wishlist url.
 *
 * @ingroup themeable
 */
#}
<p>
  {% trans %}Check out my wishlist!{% endtrans %}
</p>

<p>
  {% trans %}I use my wishlist for keeping track of items I am interested in.{% endtrans %} <br>
  {% trans %}To see the list in the store and buy items from it,<a href="{{ wishlist_url }}">click here</a>.{% endtrans %}
</p>

<p>
  {% trans %}Thanks for having a look!{% endtrans %}
</p>

我一直无法弄清楚如何访问我添加到树枝模板中 body[] 数组的变量。

任何帮助将不胜感激。

谢谢！
