Tag: Wishlist

I am trying to add 2 additional form fields to the Wishlist Share form where the user input will be rendered in the email. I have been able to add the fields to the form, but I am not sure how to add the user’s input in the email twig template.

Here is how I have updated the form() function:

  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'),
      '#required' => FALSE,
    );

// 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 Drupalcommerce_wishlistEntityWishlistInterface $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'));
  }

This is the function that calls the mailHandler that I have updated:

public function send(WishlistInterface $wishlist, $to, $sender_name, $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);
  }

And this is the preprocees function provided by the commerce wishlist module:

function template_preprocess_commerce_wishlist_share_mail(array &$variables) {
  /** @var Drupalcommerce_wishlistEntityWishlistInterface $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');
}

And finally the twig template for the email itself:

{#
/**
 * @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>

I haven’t been able to figure out how to access the variables I added to the body() array in the twig template.

Any help would be greatly appreciated.

Thanks!
