I have allowed a certain 'role' to change/edit fields in 'registered' users' fields. I want to receive an email in the admin's inbox detailing these changes using Rules.

I tried and failed!

Any help to achieve this?


Subject: [user, who changed the field in a registered user's profile] changed [user, whose profile settings have been changed] profile
Body: [changed by]
[user whose profile was changed]
[value of changed filed in profile]
[value changed at]

    Have you made a new account and received an e-mail? Just want to check that your e-mailing system works and that Rules is indeed the where the issue is at. – No Sssweat Dec 21 '18 at 3:06

I am giving you the alternate idea instead of using rules,you can use hook_form_alter.

use Drupal\Core\Database\Database;
use Drupal\Core\Form\FormStateInterface;
 function getCurrentUserRecord()
  $myArray = []; 
  $x = db_select('users_field_data','cw')

  foreach($x as $v){
    $myArray = $v;  
  return $myArray;

function nestle_viewalter_form_alter(&$form, \Drupal\Core\Form\FormStateInterface $form_state, $form_id) {

      if($form_id == "user_form")

            foreach (array_keys($form['actions']) as $action) {
if ($action != 'preview' && isset($form['actions'][$action]['#type']) && $form['actions'][$action]['#type'] === 'submit') {
  $form['actions'][$action]['#submit'][] = 'nestle_viewalter_form_submit';

function nestle_viewalter_form_submit(array $form, FormStateInterface $form_state)
$records = getCurrentUserRecord();

$mail = $field[mail];
$name = $field[name];

if($records->name == $name || $records->mail == $mail)  {
    drupal_set_message(t("No changes so far"), 'error');

    $mailManager = \Drupal::service('plugin.manager.mail');
    $module = 'nestle_viewalter';
    $key = 'update_profile';
    $to = 'vikram@sparxitsolutions.com';
    $send = true;
    $result = $mailManager->mail($module, $key, $to,NULL, $send);

    if ($result['result'] !== true) {
        drupal_set_message(t('There was a problem sending your message and it was not sent.'), 'error');
    else {
        drupal_set_message(t('Your message has been sent.'));

    drupal_set_message(t("Send mail"), 'status');

  function nestle_viewalter_mail($key, &$message, $params) {
 switch ($key) {
 case 'update_profile':
 $message['from'] = \Drupal::currentUser()->getEmail();
 $message['subject'] = t('Profile updated');
 $message['body'][] = 'this is a test mail from the current user as i have updated my profile.';
  • That was sweet. That makes me to ask you to send me a link which explains IN DETAIL the process of attaching this hook to drupal 8 through module. Thanks in advance. – Moonglade Dec 29 '18 at 8:11
  • Hi Vikram can you help me to make a module named inform_user_changes – Moonglade Jan 18 at 13:22
