File
- core/lib/Drupal/Core/Render/Element/Pager.php, line 69
Class
- Pager
- Provides a render element for a pager.
Namespace
Drupal\Core\Render\Element
Code
public static function preRenderPager(array $pager) {
// Note: the default pager theme process function
// template_preprocess_pager() also calls pager_query_add_page(), 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;
