Doesn't seem to work at all with CI 2.0?

[kasperfilstrup]

Hi there,

I've really looking forward to trying out your Facebook-CodeIgniter integration, but it seems like it doesn't work. Isn't it possible to try it out while working on localhost if I just register my app on facebook with http://localhost/ as URL or is it required to be online on a real domain before it works?

The issue is that I can see the login link and when I click it, I sure enough gets redirected to Facebook for login and permission granting. When I get sent back to my app on localhost, it shows my FB picture and says I'm logged in. However, it still shows the "Login" link and not anything else. :-/

Any idea what I'm doing wrong or if it it's a bug with CI 2.0?

[jackwh]

This is exactly the same problem I'm having.

Running this code:

if(!this->facebook->logged_in())
{
    echo "Logged out";
}
else
{
    echo "Logged in";
}

will always tell you that you're logged out, whether or not you're logged in. Confusing huh...

I haven't tested it online so I wouldn't know if putting on a host (other than localhost) would make a difference. Are you running yours in MAMP? Wondering if it's a MAMP configuration thing possibly...

Also - I'm pretty confident it's not a CI 2.0 issue, as Elliot's docs say http://www.haughin.com/code/facebook/ it needs CodeIgniter Reactor - new to CI 2.0.

@JackWebbHeller
I'm running WAMP.

Annoying though that no error message is thrown :-/

@mdgrech23
I couldn't finde the code you mentioned in Elliots library, so I'm assuming it doesn't use the default PHP SDK... But have no clue since the installation guide is rather sparse, so if it's required then that might be my problem. :-)

[jackwh]

@kasperfp thanks to @mdgrech23, I'm a step closer (possibly - not sure if the new error I'm getting is caused by those changes though...).

Whilst that function wasn't in Elliot's library, we can still configure the CURL parameters in ours. Change the private function _addCurl in Elliot's library to be like this:

private function _addCurl($url, $params = array())
    {
        $ch = $this->_ch;

        // !Configure CURL - see https://github.com/elliothaughin/codeigniter-facebook/issues/5#comment_801141
        curl_setopt($this->_ch, CURLOPT_SSL_VERIFYPEER, false);

        $key = (string) $ch;
        $this->_requests[$key] = $ch;

        $response = curl_multi_add_handle($this->_mch, $ch);

        if ( $response === CURLM_OK || $response === CURLM_CALL_MULTI_PERFORM )
        {
            do {
                $mch = curl_multi_exec($this->_mch, $active);
            } while ( $mch === CURLM_CALL_MULTI_PERFORM );

            return $this->_getResponse($key);
        }
        else
        {
            return $response;
        }
    }

(The 5th and 6th lines are my changes).

This no longer returns the error I was having in Issue #4 - hence why I think I'm a step closer. The new error returned reads:

exception 'facebookException' with message '400 | Request Failed - OAuthException - An active access token must be used to query information about the current user'

Now what to do...!?!

[kasperfilstrup]

If it's really that easy, can someone please tell me the point of using Elliots library?

How do you get a user's ID and/or email address in your example, mdgrech23?

[kasperfilstrup]

mdgrech23, it throws the same exception as Elliots library and as JackWebbHeller is experiencing:

" Uncaught OAuthException: An active access token must be used to query information about the current user "

Thing is, I modified Facebook.php to have the following two extra options when using curl:

$opts[CURLOPT_SSL_VERIFYHOST] = 0;
$opts[CURLOPT_SSL_VERIFYPEER] = 0;

Why? Because as default (without those two settings), it threw this error:

"Fatal error: Uncaught CurlException: 60: SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed thrown in "

So I'm not sure it's Elliots library there's something wrong with. Sound like a general issue.. :-/

[jackwh]

I tried uploading my copy (using Elliot's library) to my MediaTemple webserver. Again, same issue there, so I don't think it's a local/WAMP/MAMP problem.

Thought: @mdgrech23, in your CI config, have you changed any of this configuration in your config.php file?

/*
|--------------------------------------------------------------------------
| URI PROTOCOL
|--------------------------------------------------------------------------
|
| This item determines which server global should be used to retrieve the
| URI string.  The default setting of "AUTO" works for most servers.

| 'AUTO'            Default - auto detects
| 'PATH_INFO'       Uses the PATH_INFO
| 'QUERY_STRING'    Uses the QUERY_STRING
| 'REQUEST_URI'     Uses the REQUEST_URI
| 'ORIG_PATH_INFO'  Uses the ORIG_PATH_INFO
|
*/
$config['uri_protocol'] = "AUTO";

or...

/*

| You can optionally enable standard query string based URLs:

|
| The other items let you set the query string 'words' that will

| example.com/index.php?c=controller&m=function
|
| Please note that some of the helpers won't work as expected when

|
*/
$config['allow_get_array']      = TRUE;
$config['enable_query_strings'] = FALSE;
$config['controller_trigger']   = 'c';
$config['function_trigger']     = 'm';
$config['directory_trigger']    = 'd'; // experimental not currently in use

The reason I ask is (I believe) the access token is passed back to CI via a query string, so I was wondering whether changing any of these parameters might do the trick.

If it helps I've installed all the facebook files into a Reactor App. The error receiving is

A PHP Error was encountered

Severity: Notice

Message: facebookSession::_find_token() [facebooksession.-find-token]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "facebookResponse" of the object you are trying to operate on was loaded before unserialize() gets called or provide a __autoload() function to load the class definition

Filename: libraries/facebook.php

Line Number: 414

[elliothaughin]

Ok guys, I think I know where this issue lies. It's something to do with the find_token method, but strangely, the whole thing works fine on my system and server.

That might be because I have fast_cgi or something similar.

So, I'll get this bug squashed this weekend. Promise!

[jackwh]

Awesome - thanks Elliot! Really appreciated :)

[thocutt1020]

Dude, that will be so awesome! I'm psyched to get it integrated and see what I can do with this facebook stuff. Thanks EH!

[kasperfilstrup]

Much appreciated Elliot. Looking forward to a solution! :-)

[flcoder]

It works fine on my server hosted with EApps... you can find phpinfo() output at http://flcoder.com and the PLog app, which is nothing at the moment but the default ci-fb installation at http://flcoder.com/PLog/index.php/facebook_test . I'm brand new to CI so I'm not sure why http://flcoder.com/PLog/facebook_test doesn't serve anything. I must have installed CI wrong I'm guessing. Actually I realized there's no htaccess file to make the pretty URLs out-of-box, so this is actually expected behavior. The ci-fb installation instructions threw me off when it said check http://yoursite/facebook_test . I'm just new to CI.

For those having problems, has anyone tried just going with the standard Facebook library and seeing if they are getting different results... this would narrow the source of the problem down. There's no need to waste time picking through CI or Elliot's ci-fb library if it is actually something that has to do with php configuration.

[heriniaina]

flcoder> I don't think yours works either.

I went to http://flcoder.com/PLog/index.php/facebook_test

And I got

"An error occurred with PLog. Please try again later."

That's also what I got with mine

[flcoder]

I tested with both IE and FF from my work computer and it works as
intended. I tried uninstalling the PLog app and then going to
http://flcoder.com/PLog/index.php/facebook_test. Everything seems to
be working fine. So, at this point I'm wondering if it has to do with
browser settings. But what's really needed is another test subject to
go to the site and let us know their results. How many people are
getting an error with http://flcoder.com/PLog/index.php/facebook_test
and how many people successfully login and see their data retrieved.
So anyone reading, please let me know. I will also try testing from
my computer at home as well when I get off work.

[heriniaina]

Just tested with 3 computers in 3 different location (1 from France) and using 3 FB accounts

Always the same error, only in different languages. After login

Si è verificato un errore con PLog. Riprova più tardi.

An error occurred with PLog. Please try again later.
