17. The breadcrumbs builder¶
The sonata.admin.breadcrumbs_builder
service is used in the layout of every
page to compute the underlying data for two breadcrumbs:
- one as text, appearing in the
title
tag of the document’shead
tag; - the other as html, visible as an horizontal bar at the top of the page.
Getting the breadcrumbs for a given action of a given admin is done like this:
$this->get('sonata.admin.breadcrumbs_builder')->getBreadcrumbs($admin, $action);
