I am using Firebase module to send push notifications to a specific mobile user when a webform is submitted.
Below is my custom webform handler:
<?php namespace Drupal\my_custom_module\Plugin\WebformHandler; use Drupal\Core\Session\AccountInterface; use Drupal\Core\Serialization\Yaml; use Drupal\Core\Form\FormStateInterface; use Drupal\node\Entity\Node; use Drupal\webform\WebformInterface; use Drupal\webform\Plugin\WebformHandlerBase; use Drupal\webform\webformSubmissionInterface; use Drupal\webform\Entity\WebformSubmission; /** * Send Push Notification when a webform submission is submitted. * * @WebformHandler( * id = "Send Push Notification when a webform submission is submitted", * label = @Translation("Send Push Notification when a webform submission is submitted"), * category = @Translation("Push Notification"), * description = @Translation("Send Push Notification when a webform submission is submitted"), * cardinality = \Drupal\webform\Plugin\WebformHandlerInterface::CARDINALITY_UNLIMITED, * results = \Drupal\webform\Plugin\WebformHandlerInterface::RESULTS_PROCESSED, * submission = \Drupal\webform\Plugin\WebformHandlerInterface::SUBMISSION_REQUIRED, * ) */ class PushNotificationWebformHandler extends WebformHandlerBase { /** * {@inheritdoc} */ // Function to be fired while submitting the Webform. public function submitForm(array &$form, FormStateInterface $form_state, WebformSubmissionInterface $webform_submission) { // Get an array of the values from the submission. $values = $webform_submission->getData(); // Get (NID) from text element available on the webform. $nidvalue = $values["attached_node"]; // Load the node. $node = \Drupal\node\Entity\Node::load($nidvalue); // Get (selected_node_owner) value from the User Entity reference element available on the webform. $nodeowner = $values["selected_node_owner"]; // Get (token) value from the loaded node through the 'field_node_owner' Entity field. $usertoken = $node->field_node_owner->entity->field_user_push_token->value; // Send the Push Notification. // Token is generated by app. You'll have to send the token to Drupal. $messageService = \Drupal::service('firebase.message'); $messageService->setRecipients($usertoken); $messageService->setNotification([ 'title' => 'Hello', 'body' => 'Hello $nodeowner this is your body message', 'badge' => 1, 'icon' => 'optional-icon', 'sound' => 'optional-sound', 'click_action' => 'optional-action', ]); $messageService->setData([ 'score' => '3x1', 'date' => '2019-04-05', 'optional' => 'Data is used to send silent pushes. Otherwise, optional.', ]); $messageService->setOptions(['priority' => 'normal']); $messageService->send(); } } Everything is working as expected but the 'Variables' are not rendering any values and printed as they are.
Example:
I am expecting the body of the notification message to be something like below (Say the selected_node_owner name is "Elie Masaad"):
Hello Elie Masaad this is your body message but instead I am getting the below:
Hello $nodeowner this is your body message Module maintainer gave the below hint:
You should use a Token or simple str_replace for replacing something in string.
Can anyone guide me on how to pragmatically use tokens for my above requirement ?
'body' => "Hello $nodeowner this is your body message"$nodeowner = $values["selected_node_owner"];is returning the uid instead of the username. Any idea ?
