Subject: PHP MySQL login page won't work
The following is text created by dreamweaver CS3 to login a user. There is
something wrong with it because when I enter the appropriate information
into my fields, I get sent to failed.php instead of home.php (both were
specified by me). I have gone over the code as best I can, but I am not
nearly skilled enough to figure out what the hell the problem is. Does
anybody see anything wrong with this?
