That's a good solution for getting around multiple module instances using the same resources. The only change I would make would be to filter that input coming from $_GET. Anyone in the world can put any value for 'id'; potentially hijacking your CSS file to do their bidding. While header("Content-type: text/css"); should appropriately limit how a browser will interpret your file, it's better to be safe than sorry. I would do this: $module_id = (int) $_GET['id']; - Joseph LeBlanc Wed, 10 Feb 2010 09:23:49 +0100
