Respond to node type updates.
This hook is invoked from node_type_save() after the node type is updated in the database.
$info: The node type object that is being updated.
Note: this list is generated by pattern matching, so it may include some functions that are not actually implementations of this hook.
function hook_node_type_update($info) {
if (!empty($info->old_type) && $info->old_type != $info->type) {
$setting = variable_get('comment_' . $info->old_type, COMMENT_NODE_OPEN);
variable_del('comment_' . $info->old_type);
variable_set('comment_' . $info->type, $setting);
}
