function hook_menu_local_tasks_alter

hook_menu_local_tasks_alter(&$data, $route_name)

Alter local tasks displayed on the page before they are rendered.

This hook is invoked by menu_local_tasks(). The system-determined tabs and actions are passed in by reference. Additional tabs may be added.

The local tasks are under the 'tabs' element and keyed by plugin ID.

Each local task is an associative array containing:

• #theme: The theme function to use to render.
• #link: An associative array containing:
  • title: The localized title of the link.
  • url: a Url object.
  • localized_options: An array of options to pass to \Drupal\Core\Utility\LinkGeneratorInterface::generate().
• #weight: The link's weight compared to other links.
• #active: Whether the link should be marked as 'active'.

Parameters

array $data: An associative array containing list of (up to 2) tab levels that contain a list of tabs keyed by their href, each one being an associative array as described above.

string $route_name: The route name of the page.
