login

Im in the process of making a login script. I was thinking of doing
something like
session("User") = rs("Username")

but how do I check if a user is already logged in or not ? I mean, if the
user isnt' logged in then the session variable isnt created and I would get
an variable error of some kind. Just looking for some input.

Cheers

check the form text field name and compare it to the session. if it matches
then the user already logged in. use something like:

if request.form("userid") = Session("userid") then
'already logged in
else
'continue processing checking against database
end if

hope this helps

The session "OBJECT" is always there. It is a collection of items...
one of which may be named "User". If that item does not exist when you
test it's value, then a blank string will be returned...

if session("User") = "" then ' Nobody has logged in yet

I mostly use an include file that does a check like this :

If Session("User") = "" then
response.redirect "login.asp"

else
'Do nothing
end if

In the login.asp you do a Select count(username) From ...... query
where you check for the Request("Username") and the Request("password")

After getting the RS do this :

If Rs.fields(0).Value > 0 then
Session("User") = strLoginName 'from the Request("Username")
else
Response.write "User not found or wrong password."
end if
