Call to undefined method Facebook::get_loggedin_user() - FBML

[coolcam262]

Hello,

 

I have no idea where to post this but basically I am trying to create a facebook application using a "Building Facebook Applications For Dummies" book but I am stuck on the first paragraph! This is the appinclude.php file:

 

<?php
require_once '../client/facebook.php';

// *** Add your Facebook API Key, Secret Key, and Callback URL here ***
$appapikey = '<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>';
$appsecret = '<xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>';
$appcallbackurl = '<http://projectstratos.com/facebook/live/>';  

// Connect to Facebook, retrieve user 
$facebook = new Facebook($appapikey, $appsecret);
// $user = $facebook->require_login(); OLD 
$user = $facebook->get_loggedin_user(); 
$is_logged_out = !$user; 

// Exception handler for invalid session_keys 
try {
  // If app is not added, then attempt to add 
  if (!$facebook->api_client->users_isAppAdded()) {
    $facebook->redirect($facebook->get_add_url());
  }
} catch (Exception $ex) {
  // Clear out cookies for app and redirect user to a login prompt
$facebook->set_user(null, null);
$facebook->redirect($appcallbackurl);
}
?>

 

And this is the index.php file:

<h1>Watch Project Stratos Live!</h1>
<?php
require_once 'appinclude.php';

echo "<p>Your user id is: $user</p>";
echo "<p>Your name is: <fb:name uid=\"$user\" useyou\"false\" /></p>";

echo "<p>You have several freinds: </p>";
$friends = $facebook->app_client->friends_get();
echo "<ul>";
foreach ($friends as $friend) {
echo "<li><fb:name uid=\"$freind\" useyou\"false\" /></li>";
}
echo "</ul>";
?>

 

The facebook.php is the current fbml version (v2.1.2-4 I think) and the content in the h1 tag is echoed however after that there is the following errror message:

 

Fatal error: Call to undefined method Facebook::get_loggedin_user() in /xxxxxx/xxxxxx/xxxxxx/xxxx/xxxxxxxxxxxxxxxxxxxxxx/facebook/live/appinclude.php on line 12

 

I have mo idea what the problem could be! I have tried changing get_loggedin_user to getUser() but I just get another error, this is aparently (according to another forum) because I "forgot" to add get_loggedin_user.

 

Thanks in advance,

Cameron

I don't know how old the book is that you are trying to use, but the bad news is that the php facebook api has changed.  That method is no longer in the api, which is why you are getting the error. 

 

The new one is here:  https://github.com/facebook/php-sdk/

[coolcam262]

The book was made in 2008 so what's the best way to make the app, should I just follow another tutorial or is there a way round it?

[darkfreaks]

you would implement it something like this...

 

<?php
require_once '../client/facebook.php';

// *** Add your Facebook API Key, Secret Key, and enable cookies
$facebook = new Facebook(array(
  'appId'  => 'YOUR APP ID',
  'secret' => 'YOUR API SECRET',
  'cookie' => true, // enable optional cookie support
));
$session = $facebook->getSession();
// $user = $facebook->require_login(); OLD 
$logged_in = $facebook->getLoginUrl(); //login
$user = $facebook->getuser()
if($session) {
// Exception handler for invalid session_keys 
try {
  // If app is not added, then attempt to add 
  if (!$facebook->api_client->users_isAppAdded()) {
    $facebook->redirect($facebook->get_add_url());
  }
}} catch (Exception $ex) {
  //logout
$is_logged_out = getLogoutUrl(); //logout
}
?>

 

[coolcam262]

That fixed appinclude.php kind of... but now, in index.php, I have this code:

 

<h1>Watch Project Stratos Live!</h1>
<?php
require_once 'appinclude.php';

echo "<p>Your user id is: $user</p>";
echo "<p>Your name is: <fb:name uid=\"$user\" useyou\"false\" /></p>";

echo "<p>You have several freinds: </p>";
$friends = $facebook->app_client->friends_get();
echo "<ul>";
foreach ($friends as $friend) {
echo "<li><fb:name uid=\"$freind\" useyou\"false\" /></li>";
}
echo "</ul>";
?>

 

With this output:

 

Your user id is:

Your name is: Facebook User

You have several freinds:

Fatal error: Call to a member function friends_get() on a non-object in /hermes/bosweb/web035/b357/ipg.projectstratoscom/facebook/live/index.php on line 9

 

Why would this be?!

[darkfreaks]

use something like

 

$friends = $facebook->api('/me/friends');

 

[coolcam262]

Hmm.. Thank you so much but this is getting ridiculous! I've got ANOTHER error:

 

 

Fatal error: Uncaught OAuthException: Invalid OAuth access token signature. thrown in /hermes/bosweb/web035/b357/ipg.projectstratoscom/facebook/client/facebook.php on line 543

 

Also, I am not getting  id or name, why would this be. Is there some sort of cheat sheet I can use to "convert" the old sdk to the new one? How simple would that be, is the basic idea the same?

[darkfreaks]

i assume line 543 is

 

catch(exception $e) {
}

 

change it to:

 

catch(FacebookApiException $e) {
}

[coolcam262]

No, it already is. I tried doing the oposite of what you said, and change the appinlcude expression, but it doesn't work either.

[coolcam262]

I'm sorry this might look like a bump but it's not, I forgot to add this and I'm not sure how to edit it. Does anyone else know of some sort of cheat sheet I could use?

[darkfreaks]

Yes use the example on github facebook SDK. its been linked above several times.

[coolcam262]

I have used this for appinclude page but now that I want to list things, I will ask a third time, is there a cheat sheet that will actually convert from the V1 SDK to V2 functions?

 

I have not got this error:

 

Fatal error: Uncaught OAuthException: An active access token must be used to query information about the current user. thrown in /hermes/bosweb/web035/b357/ipg.projectstratoscom/facebook/client/facebook.php on line 451

 

This is because I added this line:

$friends = $facebook->api('/me/friends');

 

This is the code that is causing the error on facebook.php:

 

    if (isset($result['error'])) {
      throw new FacebookApiException($result);
    }

 

where "throe new Facebook..." is the line 451.

 

Thanks

Cameron

you could use the FB class off of php classes. i am sure it is easier to figure out than the V1 stuff.

Sorry friends.... Im a newbie in PHP, but I need to learn more. With this script can I read the Facebook ID of a user with only enter to my fanpage? I need to say "Hello xxxxxxx" before she/he makes like to my fanpage.

 

Can I do that whit this?

 

Than You
