Pager

Provides a render element for a pager.

Namespace

Code

public static function preRenderPager(array $pager) {

  // Note: the default pager theme process function
  // template_preprocess_pager() also calls
  // \Drupal\Core\Pager\PagerManagerInterface::getUpdatedParameters(), which
  // maintains the existing query string. Therefore
  // template_preprocess_pager() adds the 'url.query_args' cache context,
  // which causes the more specific cache context below to be optimized away.
  // In other themes, however, that may not be the case.
  $pager['#cache']['contexts'][] = 'url.query_args.pagers:' . $pager['#element'];
  return $pager;
