Code

function google_tag_settings_form_submit($form, &$form_state) {
  if (module_exists('variable_realm') && module_exists('variable_store')) {

    // When this handler runs, $GLOBALS['conf'] will have been updated by the
    // form submitted values (this includes realm and non-realm specific
    // variables). However, the variable stores maintained by variable_realm
    // will not reflect these changes. To counteract this behaviour refresh the
    // internal variable stores.
    //
    // Example: Assume a language realm with 'en' (default) and 'fr' keys.
    //
    // Because of how variable_realm_switch() works, the values for one or more
    // realm:key pairs will include the OLD global (i.e. not realm-specific)
    // values in effect at form build not the NEW values included with the form
    // submission. Whether one or more is stale depends on the realm of the URL:
    //
    //   default: /admin/config/system/google_tag
    //   realm: /fr/admin/config/system/google_tag
    //
    // The result does not depend on whether any google_tag variables are
    // configured to be realm-specific.
    //
    // The global:default snippet files always reflect the NEW global values
    // plus the realm-specific values for the realm of the URL. If the form is
    // submitted from the 'en' (or default) URL, then these files have the 'en'
    // values.
    //
    // The language:en snippet files have OLD global values if the realm URL is
    // language:fr (indicated by 'fr' prefix), NEW values otherwise. Any realm-
    // specific values are from language:en.
    //
    // The language:fr snippet files always have OLD global values. Any realm-
    // specific values are from language:fr.
    // Load variables from cache or database.
    // Merge with current global to get values from settings.php.
    $variables = variable_initialize();
    $variables = array_merge($GLOBALS['conf'], $variables);

    // recursive?
    // Reset internal store with updated variables.
    $global = variable_realm_controller('global');
    $global
      ->addStore('default', $variables);
  }

  // Set global to avoid message display to non-admin users on cache flush.

  $_google_tag_display_message = TRUE;
