I have a theme which sets breadcrumbs like this:
function mytheme_process_node(&$variables) { (....) drupal_set_breadcrumb($my_breadcrumbs_array); } This gets overwritten later by something else. I need a specific taxonomy value of the displayed node to set the breadcrumb, that's why I am using this hook. How to do it effectively? Perhaps there is a hook which is performed later and still has access to the node object?
I normally stick that logic in hook_preprocess_page(), it runs late enough in the page build to not be overwritten by anything else.
You can still get access to the node object by using the menu_get_object() function:
function MYTHEME_preprocess_page(&$vars) { if ($node = menu_get_object()) { // We're on a node page... drupal_set_breadcrumb($my_breadcrumbs_array); } } There is also hook_menu_breadcrumb_alter()
Besides, you can use one of the plenty of breadcrumb-customizing modules and might get what you want without custom code.
