<?php
// 
//  Create Alias
// Receives a template and a new alias and will adjust the alias of each of those docs
$template = $modx->getOption('template',$scriptProperties,'1');
$newAlias = $modx->getOption('alias',$scriptProperties,'1');
$changeddocs = $modx->getCollection('modResource',array(
    'template' => $template
)); 
foreach($changeddocs as $thisdoc){
  $thisdoc->set('alias',$newAlias);
  $thisdoc->save();
