Martin: Lot's of reasons why you shouldn't trust user input. The best book I've read covering the subject has been: Essential PHP Security (Paperback) by Chris Shiflett <http://www.amazon.com/gp/product/059600656X/sr=8-1/qid=1150552179/ref=pd_bbs_1/102-6441978-4633725?%5Fencoding=UTF8> In my opinion, it's a "must read" if you care about security. tedd PS: The author also attends this list -- ------------------------------------------------------------------------------------ http://sperling.com http://ancientstones.com http://earthstones.com
