_menu_translate(&$router_item, $map, $to_arg = FALSE)

Handles dynamic path translation and menu access control.

When a user arrives on a page such as node/5, this function determines what '5' corresponds to, by inspecting the page's menu path definition, node/%node. This will call node_load(5) to load the corresponding node object.

It also works in reverse, to allow the display of tabs and menu items which contain these dynamic arguments, translating node/%node to node/5.

Translation of menu item titles and descriptions are done here to allow for storage of English strings in the database, and translation to the language required to generate the current page

Параметры

$router_item A menu router item

$map An array of path arguments (ex: array('node', '5'))

$to_arg Execute $item['to_arg_functions'] or not. Use only if you want to render a path from the menu table, for example tabs.

Возвращаемое значение

Returns the map with objects loaded as defined in the $item['load_functions. $item['access'] becomes TRUE if the item is accessible, FALSE otherwise. $item['href'] is set according to the map. If an error occurs during calling the load_functions (like trying to load a non existing node) then this function return FALSE.
