This question was asked already, but the accepted answer is not helpful as the poster seems to have figured it out themself and left out how they got the access token.
Posting on Facebook wall from Codeigniter app
Anyhow, it seems that I can redirect to the login url and log in , but its not finding the auth token. Throwing this error:
Fatal error: Uncaught OAuthException: An active access token must be
used to query information about the current user. thrown in
/home/howekevin/biologicalfinder.com/dev/application/libraries/base_facebook.php
on line 1040
Also, if you use the example on the SDK and var_dump $user, I'm getting int 0 even after I'm logged in. I notice it's using a lot of $GET array stuff, and CodeIgniter doesn't jive with that. Has anyone solved this issue?
Ahh, so you found Elliot's broken code. Give my oauth library a spin:
http://getsparks.org/packages/codeigniter-oauth/versions/HEAD/show
Or Phil Sturgeon's:
http://getsparks.org/packages/oauth2/versions/HEAD/show
Our code should actually work ; )
Mind you mine and Phil's libraries only handle auth, but seems that's what you're having trouble with at the moment (and it's the hardest part). Check out the Facebook developer docs for the rest (if you can make a POST request, you can do this).

I tried to get Data from Facebook Page with the graph of Facebook but I have a problem.
When I try to go on link like:
https://graph.facebook.com/ID-PAGE?access_token=MY_ACCESS_TOKEN
I always do this to have the Data from a Page but since today I have the error Message: "An unknown error has occurred".
Thanks for help.
EDIT:
The bug is fixed : https://developers.facebook.com/bugs/486654544831076/?search_id
Have a look at my answer at
How to get user email and birthday from Facebook API Version v2.4
You have to specify each field you want to query now with v2.4. If you want to explicitly use v2.3, you need to prepend your calls by /v2.3 like this:
/v2.3/{page_id}?access_token=MY_ACCESS_TOKEN
Seems like there's currently a bug regarding requests made with app access tokens instead of user access tokens:
https://developers.facebook.com/bugs/486654544831076/
At this moment, I pretty much figured out what is happening, and it looks like a bug in the Facebook API.
For v2.3 and lower:
The /PAGE-ID call will return an Unknown server error when you don't pass ?fields=username (for example). If you do pass the fields option, it will work. You can get it out of the docs.
For v2.4:
This will work, but you will miss a lot of data, so you'll also have to pass the fields options. But if you don't pass that, this version will give you back only the most basic of details. This is as described in the version release: https://developers.facebook.com/blog/post/2015/07/08/graph-api-v2.4/
So the solution for now, would be to add the ?fields= everywhere you need, or to wait for Facebook to maybe ever solve it.
(And while you're at it, you might as well upgrade to v2.4 ;-)
Sometimes, when I post a reply to a comment through the graph API on a FB page (replies are enabled in the page parameters), I get generic FB "transient" errors which are not transient:
{u'error': {u'code': 2, u'message': u'An unexpected error has occurred. Please retry your request later.', u'is_transient': True, u'type': u'OAuthException'}}
A typical example is: https://www.facebook.com/VoyagesSncf.com/posts/377070219021428 where I cannot even post replies myself using the FB web interface.
I wonder if someone would know what could cause this specific FB discussion to behave this way and what I could do to detect programmatically that I need to give up on posting a reply and s
It seems to be a facebook api's bug, reported here: https://developers.facebook.com/bugs/281179468741734/
I've got the same problem while creating a new (even unpublished) post. But it is transient indeed, but it may took a few ours, when facebook will behave as expected.
I'm afraid, there is no workaround for this issue for now.
When my app tries to post on "friends wall" sometimes i receive this error:
{"error":
{"message":"(#1) An error occured while creating the share",
"type":"OAuthException",
"code":1}
}
I'm sure to have (and to use) long access_token and publish_stream permission, in fact sometimes it works and sometimes not.
Do you have any idea about the cause of the problem?
The ability to post on a friend's wall has been deprecated and will be removed in 90 days (for the reasons described in this blog post: https://developers.facebook.com/blog/post/2012/10/10/growing-quality-apps-with-open-graph/
Whilst that doesn't directly answer your question, it does make it moot and you should take an alternative approach (also described in the post)
I am at this step in getting my app started in the documentation:
https://developers.facebook.com/docs/appsonfacebook/tutorial/#auth
In there is a code block that (supposedly) forwards the user to a request dialog asking permission to access certain bit of information about them. I've placed this code block into the PHP script that my canvas URL points to, and changed the $app_id and $canvas_page to my application ID and canvas URL respectively. Instead of getting the expected dialog, I receive this following error from facebook:
"An error occurred. Please try again later."
No other details about the error are present. I've tried some variations of the script, and have even tried loading up this URL directly just to see if that would work. Note that I've replaced YOUR_APP_ID and YOUR_CANVAS_PAGE with the appropriate values and made sure that spelling and/or punctuation are correct:
https://www.facebook.com/dialog/oauth?client_id=YOUR_APP_ID&redirect_uri=YOUR_CANVAS_PAGE&scope=email,read_stream
For the redirect URL, I've tried prepending it with http://, https://, and no prefix at all. All with the same result.
My question: is the example in the documentation broken, or is the oauth link provided in the documentation currently down? The vague nature of the error is somewhat frustrating since I can't tell if it's something I'm doing wrong or if it's facebook's oauth function that's at fault.
So, the problem was that instead of using the numeric application ID that facebook assigned for me when I originally created the app as the YOUR_APP_ID parameter in the OAuth URL, I was using the application namespace string. Facebook didn't understand this sort of request, and returned the generic error message.
Once I used the numeric app ID, the OAuth dialog popped up to ask permission to access my account, as expected.
Well i started of by following all the instructions here:
http://code.google.com/p/xmppframework/wiki/FacebookChatHowTo
I used the recommended fork of the facebook api and tried the latest from:
https://github.com/facebook/facebook-ios-sdk/
My problem starts with the following error:
< failure xmlns="urn:ietf:params:xml:ns:xmpp-sasl">< not-authorized/></failure>
The error is a reply from facebook to xmppframework s response to a authentication challenge. The response that is made by the iphone is base64 encoded msg when i decode it i find 2 of the values are null:
api_key=(null)
and the
session_key=(null)
This is obviously the reason facebook is returning that error. But the problem i have is i cant seem to find any where to set these values in the framework. Besides i think the session_key should be pulled in from facebook anyway.
I guess what i want to know is a couple of things.
Has any one got the xmppframework working with facebook on a iDevice?
If you have got it working did you have to stray from the path of the instructions on http://code.google.com/p/xmppframework/wiki/FacebookChatHowTo ?
do you know of any other method to get facebook chat working on the iphone?
Any suggestions or help for my current dilemma would be appreciated. Happy to share my code if you want.
cheers
I wrote the Facebook integration for XMPPFramework. The api_key and session_key, come from a call to auth.PromoteSession. Facebook is trying to deprecate that call, so to enable it, you must follow step 7, in the HowTo:
Under Migrations, change Disable Deprecated Auth Methods from Enabled to Disabled and Save Changes.
