File

Module to apply access grants to pre-published content just as they are to published content and to make multiple content access modules work together in the expected way.

Code

function module_grants_menu_alter(&$items) {

  // As module_grants_node_access() fixes the problem of grants not being
  // checked when a node isn't published, all node access menu links are
  // altered to use function module_grants_node_access().
  // For normal view/edit/delete operations module_grant_node_access() is
  // called directly, for the revision-specific operations the function is
  // called via module_grants_node_revision_access().
