Implementation of hook_field_access().

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, $account = NULL, $node = NULL) {
  if (!$node) {
    return TRUE;
  }
  $node = node_load($node->nid);

  // The node object can be a views result object too: not good
  $sid = workflow_node_current_state($node);
  if (!$sid) {
    return TRUE;
  }
  if (!is_numeric($sid)) {
    $sid = db_result(db_query("SELECT sid FROM {workflow_states} ws \n                               LEFT JOIN {workflow_type_map} wtm ON ws.wid = wtm.wid \n                               WHERE wtm.type = '%s' AND ws.sysid = %d", $node->type, WORKFLOW_CREATION));
  }

  // Check for visible/editable flags.
  list($visibles, $editables) = _workflow_fields_compute_permissions($sid, $node->type, $node, $op);
  if (!isset($visibles[$field['field_name']])) {
    return TRUE;
  }
  return $op == 'view' ? $visibles[$field['field_name']] : $visibles[$field['field_name']] && $editables[$field['field_name']];
}
