[twitter-dev] Re: Check if user is already logged in?

2010-11-20 Thread Patrick Golden

Thanks. But I know how to do that. I mean when the user returns to the
site, generally just like a remember me cookie. The Facebook API
checks for a current Facebook session so long as the user has
activated the app, so it behaves like a cookie by automatically
logging the user in. My custom user system also does this. So I wanted
to know if I could do this with Twitter as well so that all three user
systems behaved the same way.

 With TwitterOAuth you have to maintain your own sessions. When you get a
 users access token save that into $_SESSION or save something like
 $_SESSION['twitter_users_auth']
 = TRUE. Check if that is set and if it is not you know the user is not
 currently logged into your site with Twitter.

  Is it possible to check to see if a user is logged in to Twitter and

  For first time login, I have this basic code:
  ?
  require(twitter/twitteroauth.php);
  session_start();

  // The TwitterOAuth instance
  $twitteroauth = new TwitterOAuth('xxx', 'xxx');
  // Requesting authentication tokens, the parameter is the URL we will

  $request_token = $twitteroauth-getRequestToken('xxx');

  // Saving them into the session
  $_SESSION['twitter_token'] = $request_token['oauth_token'];
  $_SESSION['twitter_secret'] = $request_token['oauth_token_secret'];

  // If everything goes well..
  if($twitteroauth-http_code==200){
     // Let's generate the URL and redirect
     $url = $twitteroauth-
  getAuthorizeURL($request_token['oauth_token']);
     header('Location: '. $url);
  }
  ?

  That's on a separate page, something like twitter-login.php, so I
  only want to use that when the user isn't logged in (i.e. the user
  clicks a login with Twitter link).

  I have a function for my site's user system that displays either a
  login form (if not logged in; has Facebook/Twitter buttons) or a user
  control panel (if logged in). The function prototype is something
  like:
  displayLogin(bool $facebook, bool $twitter, string $username)
  where the first two parameters indicate if the user is signed in with
  Facebook, Twitter, or neither.

  With Facebook, I can check with the API if the user has a session on
  Facebook and has verified the application by:
  $session = $facebook-getSession();
  $me = null;
  // Session based API call.
  if ($session) {
   try {
         $uid = $facebook-getUser();
         $me = $facebook-api('/me');
   } catch (FacebookApiException $e) {
         error_log($e);
   }
  } else {
         $me = false;
  }

  if ($me) {
    // do stuff because the user is logged in and has authorized the
  app in the past
  }

  And so if $me isn't false, I know the user is logged in and I can set
  session variables, and pass a boolean true to the displayLogin()
  function for Facebook. All of this is processed on my index page,
  hence no redirects.

  Is there any way to do this with Twitter without having to do the
  redirect? Would I have to use javascript or something? My PHP library
  is the twitteroauth library.

  Thank you!

Actually, I /could/ just use a cookie for that, right? Just set a
special Twitter cookie and when the user returns, redirect them to the
auth/login page if they don't have a session set but do have the
cookie set. I think that would work. It's not as seamless as Facebook
but oh well. =P
