Simple Question: Checking to see if username and password exist

<i><b>Originally posted by : East (alan.easton@unn.ac.uk)</b></i><br />Hi All,<br /><br />I have a registration form for new users. They choose a username and password before they submit their details.<br /><br />What I need to do is check in the DB whether or not someone already exists with these same username and password. If they do, redirect the user to a screen saying choose new password or username, and if they don't already exist in the DB, simply store their details in the DB.<br /><br />Any help would be appreciated,<br /><br />Thanx...8')
