This module adds to workflow.module the ability to specify, for each state, which node fields should be visible and/or editable. It is a useful feature when workflows demand that certain information be hidden or read-only to certain roles.

Code

function workflow_fields_field_access($op, $field, $entity_type, $node, $account) {
  if ($entity_type == 'node' || !$node) {
    $sid = NULL;
    $workflow_fields = array(
      '',
    );

    // Workflow 2+
    if (function_exists('_workflow_info_fields')) {
      $workflow_fields = _workflow_info_fields($node, $entity_type);
      if (0 === count($workflow_fields)) {
        return TRUE;
      }
    }

    // If there is one workflow that gives access to the field, access is granted
    foreach ($workflow_fields as $workflow_field_name => $workflow_field_info) {
      $sid = workflow_node_current_state($node, 'node', $workflow_field_name);
      if (FALSE === $sid) {
        $type_map = workflow_get_workflow_type_map_by_type($node->type);
        if (!$type_map) {
          return;
        }

        // Workflow 1.x
        if (function_exists('workflow_get_creation_state_by_wid')) {
          $sid = workflow_get_creation_state_by_wid($type_map->wid);
        }
        else {
          $workflow = workflow_load($type_map->wid);
          $sid = $workflow
            ->getCreationSid();
        }
      }

      // Check for visible/editable flags.
      list($visibles, $editables) = _workflow_fields_compute_permissions($sid, $node->type, $node, $op);
