probably best *not* to store the uname / pwd combo in a cookie unless
you have encrypted the string sufficiently for it to not be easily readable

OK, it seems like you need help with the logic behind this:
(1) at the beginning of your log in script, check for the cookie
existance, decrypt it and use the values to log the individual in
automatically (users can use their browsers to remember uname / pwd
combo's so it is not much use to emulate this IMHO)
(2) If the cookie doesn't exist, display your log in form
(3) on the login process part of your script - check for the value of
the checkbox, if it is set to "checked", use the setcookie function to
write a cookie to the users browser
does that help?
