[Question] Is there any example on how to create webform mutation?

[sixtyniner-official]

Hi all,

I'm trying to send email using mutation and webform module. For now I've created EmailInput.php as InputType and SendEmail.php as Mutations, basically just copy code of CreateArticle.php and ArticleInput.php

I'm able to create new Webform Submission, but not sure how to send and save values, so submissions are empty.

SendEmail.php

<?php

namespace Drupal\graphql_examples\Plugin\GraphQL\Mutations;

use Drupal\graphql\Annotation\GraphQLMutation;
use Drupal\graphql\GraphQL\Execution\ResolveContext;
use Drupal\graphql_core\Plugin\GraphQL\Mutations\Entity\CreateEntityBase;
use GraphQL\Type\Definition\ResolveInfo;

/**
 * Simple mutation for creating a new article node.
 *
 * @GraphQLMutation(
 *   id = "send_email",
 *   entity_type = "webform_submission",
 *   entity_bundle = "sidebar_contact",
 *   secure = true,
 *   name = "sendEmail",
 *   type = "EntityCrudOutput!",
 *   arguments = {
 *     "input" = "EmailInput"
 *   }
 * )
 */
class SendEmail extends CreateEntityBase {

  /**
   * {@inheritdoc}
   */
  protected function extractEntityInput(
    $value,
    array $args,
    ResolveContext $context,
    ResolveInfo $info
  ) {
    return [
      'email' => $args['input']['email']
    ];
  }
}

EmailInput.php

<?php

namespace Drupal\graphql_examples\Plugin\GraphQL\InputTypes;

use Drupal\graphql\Plugin\GraphQL\InputTypes\InputTypePluginBase;

/**
 * The input type for article mutations.
 *
 * @GraphQLInputType(
 *   id = "email_input",
 *   name = "EmailInput",
 *   fields = {
 *     "email" = "String",
 *   }
 * )
 */
class EmailInput extends InputTypePluginBase {

}

Any help is appreciated.
