Trying to se $_COOKIE in PHP but having trouble ....

Hey all.

I have a PHP program (PHP is not my forte) and am having trouble when trying to use a set cookie for authentication.

In the following code, the first time through the user ID and password is used to authenticate. If authenticated, a cookie is set on the user's machine.

The way it "should" work is that for future calls, the cookie should be used first to authenticate and if it's not valid, then check for user ID / password.

I have verified that the cookie is in fact being created in the correct domain, but it is not being used for authentication due to it not "being found". Again, the cookie is on my machine but the PHP code, when checking if it's "empty", does *not* find it.

In the "try" block, I've tried using the incoming id / password as well as this:

$_COOKIE['loginapp.token_key'] = $loginapp->authenticatePrincipal(
                        $_SERVER['PHP_AUTH_USER'],
                        $_SERVER['PHP_AUTH_PW'],
                        $_SERVER['HTTP_USER_AGENT'],
                        $_SERVER['REMOTE_ADDR']
                  );

If the cookie "is found", should it not use that and *not* the id / password for authentication?

Any help would be greatly appreciated.

try adding this to the start of your script to see what is in $_COOKIE

print_r($_COOKIE);

or

var_dump($_COOKIE);

enclose in <pre> tags to better see the output if required.

This might shed some light

Add this after $is_authenticated = FALSE;

if(isset($_COOKIE["loginapp.token_key"]))
{
  echo "Cookie loginapp.token_key exists: ";
  var_dump($_COOKIE["loginapp.token_key"]);
  die();
}

Well, that help to fix the issue but I'm still confused.

The cookie was being set with a ".", 'loginapp.token' but when using the command you gave, it came back with loginapp_token. The period was an underscore.

I changed all the periods to underscores and now it works. On my machine, even now when looking, I see the "period" version, not the underscore. I deleted the cookie and it doesn't find it anymore.

I'll get it recreated, but if it is being set with an underscore, why does the name (in Google Chrome) show as a period?

Also this is an age old issue

  setcookie('loginapp.token_key', $_COOKIE['loginapp.token_key'], time() + 3600, '/', '.mydomain.com');

There is NOTHING in the $_COOKIE at this point BECAUSE $_COOKIE gets its value from the REQUEST and you have not yet sent that request back to this script from the client

            print 'COOKIE: '.$_COOKIE['loginapp.token_key'].'<br>'; // empty until next time
