Code

function rb_misc_load_variant_context_entities($handler, $base_contexts) {

  // Get a list of all entity types supported by Rules, and a list of fully
  // loaded objects provided as contexts in the variant.
  $supported_entity_types = rb_misc_entity_keys();
  $potential_entities = ctools_context_handler_get_handler_contexts($base_contexts, $handler);

  // Build the list of objects to send as variables to Rules.
  $entities = array();
  foreach ($potential_entities as $entity_name => $potential_entity) {

    // Check the types for each potential entity, to see if any matches the
    // types handles by Rules (or, rather, Entity API).
    foreach ($potential_entity->type as $type) {
      if (isset($supported_entity_types[$type])) {

        // The variable name cannot contain colon or dashes.
        $id = str_replace(':', '__', $entity_name);
        $id = str_replace('-', '_', $id);
        $entities[$id] = $potential_entity->data;
