An implementation of node revision workflow for Drupal based on the State Machine system.

Code

function state_flow_node_presave($node) {

  // If the node is not new and is not marked to be ignored by
  // state_flow_promote_node_revision(), then check its current state.
  if (!empty($node->nid) && empty($node->state_flow_ignore_state)) {
    $state_flow = state_flow_load_state_machine($node);

    //Check to see if we should go through workflow
    if (empty($node->stateflow_skip_workflow)) {
      $state = $state_flow
        ->get_current_state();
      if ($state == 'published') {

        // If the node being updated is in the published state, then ensure that
        // changes are saved to a new revision.
        $node->revision = TRUE;
      }
      else {
        if ($state != 'draft') {

          // If the node being updated is not in the draft state, then mark this
          // node to be reverted to draft state.
          $node->state_flow_revert_draft = TRUE;
        }
      }

        $state_flow
          ->fire_event('publish');
      }
