hook_menu_get_item_alter

7 system.api.php hook_menu_get_item_alter(&$router_item, $path, $original_map)

Alter a menu router item right after it has been retrieved from the database or cache.

This hook is invoked by menu_get_item() and allows for run-time alteration of router information (page_callback, title, and so on) before it is translated and checked for access. The passed-in $router_item is statically cached for the current request, so this hook is only invoked once for any router item that is retrieved via menu_get_item().

Usually, modules will only want to inspect the router item and conditionally perform other actions (such as preparing a state for the current request). Note that this hook is invoked for any router item that is retrieved by menu_get_item(), which may or may not be called on the path itself, so implementations should check the $path parameter if the alteration should fire for the current request only.

Parameters

$router_item: The menu router item for $path.

$path: The originally passed path, for which $router_item is responsible.

$original_map: The path argument map, as contained in $path.
