The reason for this is because the data that Jack enters could potentialy affect the data that Jill enters. Example: Jack is an administrator at a forum somewhere. Jack is editing a post that Jill entered to remove inapropriate content. Meanwhile Jill is editing the same post to revise what she said seeing that it could be mistaken for being inappropriate. Jack saves, Jill Saves...Jacks stuff is lost. OK that example is poor I admit...but do you see the reasoning behind locking? If a lock was in place Jill would't be able to edit her post because she would get a message stating that Admin Jack was allready editing it. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
