UBB.Developers Forums UBB.threads 6 Bug Reports Problems with cookies

I believe the persistent login problem has to do with domain.com versus www.domain.com. I wrote a game that required user authentication. I was getting the same problem because I sort of learned how to do it by examining your code. It had to do with how you set the cookie.

The code I ended up using that worked without a hitch was the following:

code:

// after successfull login username/password match
function set_cookies($name,$pass)
{
   global $myname,$mypass;

   $Password_e = crypt_password($pass);
   setcookie("myname","$name",time()+31536000,"/",".mydomain.com");
   setcookie("mypass","$pass",time()+31536000,"/",".mydomain.com");
}

// logout code
function clear_cookies()
{
   global $myname,$mypass;

   setcookie("myname","",time()-3600,"/",".mydomain.com");
   setcookie("mypass","",time()-3600,"/",".mydomain.com");
}

Now when you set cookies you don't specify the domain name. So it gets confused if people switch between www.domain.com and just domain.com. For example, your code:

code:

setcookie("w3t_myid","$Uid",time()+$config'cookieexp'],"{$config['cookiepath']}");

A lot of people describe this same problem:

-They login.
-It looks like they logged in successfully
-When they click on the index it tells them they haven't actually logged in properly. Invalid username/password.

When people described the problem along those lines I would tell them to do the following which seemed to fix it:

- Go to http://www.domain.com/board/logout.php
- Try logging in again.

Then they would tell me that it worked.
