Re: [PHP] lock web page when editing From: Bob (whyisityou2 <email protected>)
Date: 09/30/01

Hey thanks guys I think I've decided on locking it cuz I don't want multiple
people to be editing and then having them click "save" and say "sorry all the
work you just did can't be used". I'm going to just put a 10 minute limit and
have a status like "please wait ... bob has been editing for 4:39 minutes"
