Drupal 8.x

I am currently using hook_preprocess_user().

I would like to alter the username to add some custom markup to every username.

MYMODULE.module:

function MYMODULE_preprocess_user(&$variables) {

  $variables['elements']['#user']->name->value = t('Name @newMarkup', ['@newMarkup' => ' Hello']);

}

This returns Name Hello Hello. Concatenation adds 'Hello' twice so this approach is not working.

I've also worked with user_format_name_alter(&$name, $account), however, this does not seem to fit my use case.

How can I alter the username text? Not looking for a "currentUser" solution, but every user so names are changed everywhere. Reference, Views, etc.

Seems hook_user_format_name_alter() is your best bet. But same as in the other answer markup doesn't seem to be allowed everywhere. Normally the user name is only allowed to be a string.

The following won't work for Views for example. It will print just a string.

use DrupalCoreStringTranslationTranslatableMarkup;



/**

 * Implements hook_user_format_name_alter().

 */

function MYMODULE_user_format_name_alter(&$name, $account) {



  $name = new TranslatableMarkup('@name <span class="foo-bar">Foo Bar</span>', ['@name' => $name]);

}



/**

 * Implements hook_preprocess_HOOK().

 */

function MYMODULE_preprocess_page_title(&$variables) {



  if (Drupal::routeMatch()->getRouteName() == 'entity.user.canonical') {



    $name = $variables['title']['#markup']->__toString();

    $variables['title'] = new TranslatableMarkup('@name <span class="foo-bar">Foo Bar</span>', ['@name' => $name]);

  }

}

So, what I'd recommend now is, you maybe take the *_preprocess_page_title hook – as this is working just fine on user pages – and for all other places (references, Views etc.) you maybe create a new custom formatter or pseudo field to do the job.

<?php

use DrupaluserEntityUser;



// Updating a user is a three step process:

// 1) load the user object to change

// 2) set property/field to new value

// 3) Save the user object.



// This example updates the user name.



// $uid is the user id of the user user update

$user = DrupaluserEntityUser::load($uid);



// Don't forget to save the user, we'll do that at the very end of code.



// Modify username

$username = $user->getUsername();

$username .= " Hello";

$user->setUsername($username); // string $username: The new user name.



// The crucial part! Save the $user object, else changes won't persist.

$user->save();



// Congratulations, you have updated a user!

I based this on the examples in this Github gist:
