How do I programmatically update or delete menu items?

Question

I have seen How do I create menu links programmatically? but how do I update or delete menu items in Drupal 8?

By programmatically, I mean dynamically; YAML configuration files are not going to help.

Answer 1

First you will have to load the entity. Either way works:

$menu_link = MenuLinkContent::load($menu_link_id);

or ...

$menu_link = \Drupal::entityTypeManager()->getStorage('menu_link_content')->load($menu_link_id);

Next you can update value using set() method or through the magic method __set...

$menu_link->expanded = TRUE;

To save, simply call the save() method. To delete, simply call the delete() method.

Answer 2

I had to do some thing like ....

 
 //menuLinkManager = 'plugin.manager.menu.link'
$result = $this->menuLinkManager->loadLinksByRoute('entity.node.canonical', ['node' => $node->id()]);
foreach ($result as $menu_item) {
          if (is_object($menu_item)) {
            $id = $menu_item->getPluginDefinition()['metadata']['entity_id'];
$menu_link = $this->entityTypeManager->getStorage('menu_link_content')->load($id);
$menu_link->enabled = 0;
$menu_link->save()

Probably too late I did like:

$menu_handler = \Drupal::service('menu.link_tree')
    ->load("menu-name", new \Drupal\Core\Menu\MenuTreeParameters());
foreach($menu_handler as $key=>$value) {
  if('Name' == $value->link->getTitle()) {
    $link = $value->link;
    $link->updateLink(
      [
        'enabled'=>'1',
        'title'=>'New Name'
      ],
      true
    );
  }
}

This is how i delete all the links in a particular menu like footer

$old_menu_links = \Drupal::entityTypeManager()->getStorage('menu_link_content')
  ->loadByProperties(['menu_name' => 'footer']);
foreach ($old_menu_links as $old_menu_link) {
  $old_menu_link->delete();
}

And to update existing menu,

$menu_links = \Drupal::entityTypeManager()->getStorage('menu_link_content')
  ->loadByProperties(['menu_name' => 'footer']);
foreach ($menu_links as $menu_link) {

  if ($menu_link->gettitle() == 'old-title') {
    $menu_link->set('title', 'new-title');
    $menu_link->save();
  }
}

This turned out to be insanely complicated. Apparently not every menu link is a MenuLinkContent object. Sometimes it is a MenuLinkDefault object. In that case, you cannot use ->set() or ->save(). This is the most complete answer to cover both cases. Put this inside of an hook_update_n() and change $disabled_routes and $menu to your needs. In this example I am disabling menu links.

  $disable_routes = [
    '<front>',
    'view.frontpage.page_1',
    'private_message.private_message_page',
    'view.opigno_calendar.page_month',
  ];

  $menu_name = 'main';

  $menu_link_manager = \Drupal::service('plugin.manager.menu.link');
  $menu_link_tree_elements = \Drupal::service('menu.link_tree')
    ->load($menu_name, new \Drupal\Core\Menu\MenuTreeParameters());

  foreach ($disable_routes as $disable_route) {
    foreach ($menu_link_tree_elements as $key => $menu_link_tree_element) {
      $menu_link_default = $menu_link_tree_element->link;
      $plugin_definition = $menu_link_default->getPluginDefinition();
      $link_route = $plugin_definition['route_name'];
      if ($link_route == $disable_route) {
        $uuid = $menu_link_default->getDerivativeId();
        if (!empty($uuid)) {
          $menu_link_content = \Drupal::service('entity.repository')
            ->loadEntityByUuid('menu_link_content', $uuid);
          $menu_link_content->set('enabled', 0);
          $menu_link_content->save();
        }
        else {
          $menu_link = $menu_link_manager->getDefinition($key);
          $menu_link['enabled'] = 0;
          $menu_link_manager->updateDefinition($key, $menu_link);

          // Not sure if this is necessary.
          $menu_link_default->updateLink(
            [
              'enabled' => 0,
            ],
            true
          );
        }
      }
    }
  }
