function workbench_moderation_menu_local_tasks_alter in Workbench Moderation 7.3

Same name and namespace in other branches

1. 7 workbench_moderation.module \workbench_moderation_menu_local_tasks_alter()

Implements hook_menu_local_tasks_alter().

Hide the node revisions tab conditionally.

Check if the node type is subject to moderation. If so, unset the revision tab. This step is necessary because hook_menu_alter cannot change the menu item type on a node type by node type basis for node/%node/revision.

Additionally, workbench_menu_alter() is used to change the page callback for node/%node/revisions so that this URL redirects to node/%node/moderation for node types subject to moderation.

  // Do we need to bother doing anything?
  if (empty($data['tabs'][0]['output'])) {

  }

  // Check the path.
  $arg = arg(0, $root_path);
  $arg1 = arg(1, $root_path);
  if ($arg != 'node' || $arg1 != '%') {
    return;
  }

  // Get the node for the current menu router.
  if ($node = menu_get_object()) {

    // Here is the reason this hook implementation exists:
    // If this is a node that gets moderated, don't show 'node/%/revisions'

          unset($data['tabs'][0]['output'][$key]);
          $data['tabs'][0]['count'] -= 1;
          break;
