File

Enables the user registration and login system.

Code

function template_preprocess_username(&$variables) {
  $account = $variables['account'] ?: new AnonymousUserSession();
  $variables['extra'] = '';
  $variables['uid'] = $account
    ->id();
  if (empty($variables['uid'])) {

  // Set the name to a formatted name that is safe for printing and
  // that won't break tables by being too long. Keep an unshortened,
  // unsanitized version, in case other preprocess functions want to implement
  // their own shortening logic or add markup. If they do so, they must ensure
  // that $variables['name'] is safe for printing.

    // easier for other preprocess functions to append to it.
