Feeds Usermapper
If you are using Feeds to migrate site content, one of the stumbling blocks will be preserving content ownership.
This code is taken from a hypothetical feeds_usermapper module that provides the option to sync up node ownership on the basis of identical usernames. (Pulled from User Inheritance Issue on D.O)
/** * Implementation of hook_migrate_fields_node(). */ function feeds_usermapper_feeds_node_processor_targets_alter(&$targets, $content_type) { $targets['uid'] = array( 'name' => t('Node author'), 'description' => t('The owner of the node.'), 'callback' => 'feeds_usermapper_feeds_set_target', ); } /** * Mapping callback for author. */ function feeds_usermapper_feeds_set_target($node, $target, $value) { // [insert optional username transformation here] $user = user_load(array('name' => $value)); if (isset($user->uid)) { $node->uid = $user->uid; } }
