In other words, what is the Drupal 8 equivalent of hook_menu_alter()?
Drupal 8 still uses hook_menu(), but for what I can see, the information returned by the hook is different from what the hook returned in Drupal 7. For example, the definition given in user_menu() for user is the following.
$items['user'] = array( 'title' => 'User account', 'title callback' => 'user_menu_title', 'weight' => -10, 'route_name' => 'user_page', 'menu_name' => 'account', ); The route_name property links to an entry in the user.routing.yml file.
user_page: pattern: '/user' defaults: _content: 'DrupaluserControllerUserController::userPage' requirements: _access: 'TRUE' This is different from what done with Symphony, and it confuses me about how a module can alter the route defined from another user.
The only function that is still invoking hook_menu_alter() is menu_router_build(), but that function still contains code that needs to be updated, since it is still using the now deprecated drupal_alter().
// Alter the menu as defined in modules, keys are like user/%user. drupal_alter('menu', $callbacks); foreach ($callbacks as $path => $router_item) { // If the menu item is a default local task and incorrectly references a // route, remove it. // @todo This may be removed later depending on the outcome of // http://drupal.org/node/1889790 if (isset($router_item['type']) && $router_item['type'] == MENU_DEFAULT_LOCAL_TASK) { unset($callbacks[$path]['route_name']); } // If the menu item references a route, normalize the route information // into the old structure. Note that routes are keyed by name, not path, // so the path of the route takes precedence. if (isset($router_item['route_name'])) { $router_item['page callback'] = 'USES_ROUTE'; $router_item['access callback'] = TRUE; $new_path = _menu_router_translate_route($router_item['route_name']); unset($callbacks[$path]); $callbacks[$new_path] = $router_item; } } Sponsored by SupremePR
