Facebook recently updated their PHP-SDK to version 3.0. This is a major change. So I decided to update some of my facebook related tutorials with updated code.
At first I want to tell you that, this post is the updated version of my popular post Graph API & IFrame Base Facebook Application Development . So if you never saw that tutorial I request you to visit that and learn the basic things specially facebook application setup. Also on that post I mentioned some important things regarding iframe, so in this post I’ll not mention them again.
So in this updated post we will learn:
- How to update facebook php sdk 3.0 library
- Authentication
- How to give extended permissions
- How to call graph api
- How to publish stream using facebook’s latest dialog system
- How to request/invite your friends and track them
Before proceeding:
1. How to update facebook php sdk 3.0 library
First download Facebook’s php sdk and from the /src directory copy facebook.php, base_facebook.php and fb_ca_chain_bundle.crt to your project dir. Then download my codes from here, in this zip file you also get the php sdk libraries. Now click below image to know about the files functionality.
2. Authentication
In fbmain.php line number 23->77 you’ll see below code.
- At first we include the facebook.php library.
- Then we created a $facebook object
- Then we check if there is a valid session for user by $user = $facebook->getUser();
- Then we generate login url with extended permission
- At line number 62 we call graph api $user_profile = $facebook->api(‘/me’); to check if session is valid or not. If we get result then user’s session is valid otherwise we set $user = null that means expired or timeout session.
- If no valid $user found at line number 71 we redirect user to login/authentication page for our application.
$user = null; //facebook user uid
try{
include_once "facebook.php";
}
catch(Exception $o){
echo '<pre>';
print_r($o);
echo '</pre>';
}
// Create our Application instance.
$facebook = new Facebook(array(
'appId' => $fbconfig['appid'],
'secret' => $fbconfig['secret'],
'cookie' => true,
));
//Facebook Authentication part
$user = $facebook->getUser();
$loginUrl = $facebook->getLoginUrl(
array(
'scope' => 'email,publish_stream,user_birthday,user_location,user_work_history,user_about_me,user_hometown'
)
);
if ($user) {
try {
// Proceed knowing you have a logged in user who's authenticated.
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
//you should use error_log($e); instead of printing the info on browser
d($e); // d is a debug function defined at the end of this file
$user = null;
}
}
if (!$user) {
echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
exit;
}
After user successfully authenticated our application facebook will redirect user to our callback url that we provided in the developer application setting. Facebook additionally pass a parameter named code=XXXX . But as this is a iframe application that runs inside facebook so we used a special code at line number 16->19. This code checks if there is GET parameter code is defined or not, if its defined then it redirects user to the facebook app url.
if (isset($_GET['code'])){
header("Location: " . $fbconfig['appBaseUrl']);
exit;
}
3. How to give extended permissions
When you’ll generate the login url you’ve to provide extended permissions here. Previously the parameter named was ‘req_perms’ and now its ‘scope’.
$loginUrl = $facebook->getLoginUrl(
array(
'scope' => 'email,publish_stream,user_birthday,user_location,user_work_history,user_about_me,user_hometown'
)
);
Checkout extended permission list from here.
4. How to call graph api
In fbmain.php line number 76, you’ll see how I called the graph api. Here $user is facebook user’s UID. To know more about graph api visit this page
//get user basic description
$userInfo = $facebook->api("/$user");
5. How to publish stream using facebook’s latest dialog system
In template.php line number 50->54 you’ll see the facebook’s javascript function. To know more about feed please visit here.
FB.ui({ method : 'feed',
message: userPrompt,
link : hrefLink,
caption: hrefTitle
});
6. How to request/invite your friends and track them
So you want your user will invite his friends to use this application, and also you want to track to whom your user sends request. Also you want to check if that user is come from via request or not. In demo application click Send Request/Send Invitation to check the request dialog. In template.php line number 88 you’ll see this function.
function newInvite(){
var receiverUserIds = FB.ui({
method : 'apprequests',
message: 'come on man checkout my application. visit http://thinkdiff.net',
},
function(receiverUserIds) {
console.log("IDS : " + receiverUserIds.request_ids);
}
);
//http://developers.facebook.com/docs/reference/dialogs/requests/
}
This function show a invite dialog and if user selects friends and sends invite, then in the response you’ll get all of user’s friends UIDs as a comma separated string. So if you use Firebug in Firefox, you’ll see console.log(“IDS : ” + receiverUserIds.request_ids); will print IDS: XXXX in the console of firebug. So if you want to track the friends IDS who received invitation, then parse receiverUserIds and save them in your mysql database.
If a user authenticate your application from invitation then his URL would be
http://apps.facebook.com/[app_name]/?request_ids=012345678910
So in fbmain.php line number 23->26 you’ll see below code. I just blank them you’ve to write additional code for tracking user.
if (isset($_GET['request_ids'])){
//user comes from invitation
//track them if you need
}
I hope this tutorial will help you for developing facebook application.
Hi Mahmud,
is it possible to send friend request to multiple id’s using
FB.UI friends.add method say an array of 3 id’s?
Another question:
we can add facebook iframe app to facebook page,
similiarly , Can’t we add a app page to user profile page so that user can just use app without being redirected and the app runs inside 520px iframe??
waiting for your answers!!!
Answer of your first question, I didn’t try it so don’t know, I think you should try by giving comma separated list of friends ids and if it fails then you could try json array of friends ids in there. Answer of your 2nd question, I think this is not possible.
Hello there Mahmud!
Thanx for shareing this example… i want to get offline_access from users… how can i get the access token that i will need to do this when they are not connected to facebook?
Thanx in advance!
Hello,
In the post I’ve shown a part where you can provide extended permission.
Your articles about Facebook helped me a lot man!
God bless you \o
Thank You. I wish to publish regular post, but for my work I can’t manage time and so can’t publish regularly :S
Hi Mahmud
i am hanged our some issue i just want to post sum things on fan page in offline session.. i have go through ur old demo post but still i am facing alot of issues in getting the persmisiions or session id could you please upload the demo api to do that task plz…
Imran Athar
Hi Mahmud,
Great tutorial. I’ve just read it for the first time now and finally I have something to work with. Total noob here
Is it possible to make a form and provide the user with an option to select only one friend, for a referal programme? I’d then like to get this data: user’s name and his friend’s name, stored somehow or sent via e-mail to me.
Easier way to redirect after authentication
$loginUrl = $facebook->getLoginUrl(
array(
‘scope’=> ‘email,publish_stream,user_birthday,user_location,user_work_history,user_about_me,user_hometown’,
‘redirect_uri’ => “$fbconfig['appBaseUrl']”
)
);
It will not work, as appBaseUrl contains http://apps.facebook.com, i tried that before i write this post.
It works
, i test it and it works, the appBaseURl=http://apps.facebook.com/app_name/
These reditect into facebook application page.
did not work for me…got this error:
API Error Code: 191
API Error Description: The specified URL is not owned by the application
Error Message: Missing redirect_uri parameter.
oops…had uri instead of url……
still does not redirect to correct location.
Just gose to blank page
once again your tutorials save my day.
thanks
Great tutorial. Much less confusing than the examples I found on Facebook Dev site. You made my day! Saved alot of hair pulling and cussing. Thanks a million! BTW– What widget did you use in dreamweaver for tabs???
Thanks AGAIN!
I don’t use dreamwaver, I use NetBeans IDE. And those tabs are from jQuery UI.
Thanks a million! I just checked out netbeans IDE. SWEEET! I like it. anyway…. I do have a small issue. I modified your app to include a simple flashplayer off of my site and for the first time I am getting the redirection issues others are talking about. Any ideas on what could be wrong in my settings? I saw another post you had regarding this but I am assuming it is outdated as the solutions presented did not work. Thanks, Orlando
once again… my bad. I didn’t have the proper url in
fbmain.php
appBaseURl=http://apps.facebook.com/app_name/
after fixing this… app works fine again. Thanks!
I used your tutorial v2 it worked fine. Now that I loaded new SDK v3. I have redirection issue. After users allow permission, it keeps redirecting back & forward. never takes me to the main page.
thanks for the great tutorial. i tried your invitation dialog box, and made it into a single app. when i tried removing the authentication permission, the skip button on the invite your friends dialog box redirects to a ‘page request not found’ [url: http://www.facebook.com/plugins/serverfbml.php?
what i’m basically trying to do is making an app that just allows user to invite their friends to my facebook page, and then when they press skip, they go back to my page as well.. any help would be appreciated.. thanks!
http://developers.facebook.com/docs/reference/dialogs/requests/ I don’t see any skip button here.
my bad. i was referring to your previous tutorial.
http://thinkdiff.net/facebook/graph-api-iframe-base-facebook-application-development/
posted on the wrong article. but can you still help?
U can redirect user with javascript function to your fan page.
thanks, I looking for facebook extended permission with php
the example really usefull
Hi ,
I have some problem testing your codes. my application keeps refreshing. and i notice the problem is this code :-
if (isset($_GET['code'])){
header(“Location: ” . $fbconfig['appBaseUrl']);
exit;
}
i don’t think facebook return me anything in the parameter.
any advice?
thanks
Laurent
Laurent by removing that isset() part code and updating below part check what happens
$loginUrl = $facebook->getLoginUrl( array( 'scope' => 'email,offline_access, publish_stream, user_birthday,user_location, user_work_history, user_about_me, user_hometown', 'redirect_uri' => $fbconfig['appBaseUrl'] ) );Hi,
The problem is still the same by doing as advice.
Laurent
Hi,
Looks like $_GET does work to get the ‘code’ from the URL. as i can see the variable there. and also no idea why the
$user = $facebook->getUser();
doesn’t work too. for me only .. i checked my settings and they look good
Laurent
Did you update the latest PHP SDK 3.0 ?
sorry for my mistake
Looks like $_GET does not work to get the ‘code’ from the URL
yes, i have updated to php 3.0. let me swipe everything clean. and re-try again. as it seems some of the folks here manage to get it working
Laurent,
Were you able to get this working? I am still having issues with refresh…
Hello Mahmud,
Thank you for nice posts, really like them.
I have developmed on Iframe based app, and want to know if it is possible to add specific querystring everytime someone adds that app to page.
for e.g. i have application url as follows
http://www.facebook.com/apps/application.php?id=11111111
If two users are adding this app to their fan page want to add some kind of id in querystring, so that i know which fan page it is loading in.
Thanks
Imran
Sorry, I don’t know it :S
hi,
(i know this is an old question, but maybe still need answer)
there is a specific parameter called app_data.
for example ?app_data=111111.
but you can use only this one.
so i use it like this:
?appdata=page-gallery_galleryitem-123
which means the current page is gallery and the current item id is 123
Hi, i update to fb sdk3.0, the app working ok, but when i uninstall the app its not working.
The line
echo “top.location.href = ‘$loginUrl’;”; not working.
Hi Mahmud,
Thank you for great article and example. Thank you so much for sharing the information. I’ve tested your sample app and it works as I expected.
Thanks for reading my post.
Hi Ahsan,
I changed to version 3 of PHP SDK, and works well in all browsers except IE, it redirects endlessly. Certainly the example of a page in IE also has problems. Any idea how to fix?
Thanks
IE have some cookie issue, so write this code at the top of every page if your pages are different, or if you use the template system, then put this code at the top of that file. Hope if will fix your problem.
header('P3P:CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"');Hi, thanks to your help I could solve the problem.
Now I have a question. In your code example shows how to publish on the wall calling a popup (publishStream function) and it works fine, but I wish I could do the same for publication in the wall of a friend of my choice using the “UID”.
I searched for several days and nothing works for me. I know how to do it without the popup, but I fear I disable Facebook application (already done on other occasions).
I hope you can help me with an idea or a link.
Thanks
http://developers.facebook.com/docs/reference/dialogs/feed/ You’ll see there is a to parameter that is the ID or username of the profile that the story will be published to. So provide your target user UID or username here.
Dude thanks for the above header p3p code… you just saved my life (and by life I mean a really crappy day, but sounds way more cool that way).
Anyway, if you want to rant about IE, our spirits will be together anytime.
Glad to know it helps. IE sucks!
I wont create a simple tab application php for obtain name and surname of person liked my fan page,
i have problem to get user information, can help me? thanks
Hi Mahmud
I love your tutorials, they have helped me a lot so far…
Something I would like to implement is a button on our website from which FB connected users can invite their friends to check out our company Facebook page. With your tutorials I am able to build such a button. However, we want to offer an incentive to the users who really ‘do’ invite their friends, so we need to track who has been using the button!
Any idea how to accomplish this?
Yeah you can track then to whom they invite and you can additionally track who comes from invitation. You’ve to build your own database table for this. And follow what I said about invitation tracking in the post.
Hi there!
This is a very very useful tutorial, so first of all thanks for it!
Enligh is not my mother language, and my problem’s a bit complicated, but I hope you’ll understand it.
There’s an applicaion on fb called Static Iframe Tab (http://www.facebook.com/add.php?api_key=9b6c3032a5f661005f6c5a11f8c57377&pages) that which you can make a static html page with and put it on your page as a tab.
I’d like to do something like this.
The first time i opened this app, a dialog came up asking if I wanted to put it on my page as a tab. How can I call this dialog? I couldn’t find any information about it.
Hi there again!
I realized, that add.php is doing what i need. Is that right? I just want to know how could i get the id of the facebook page where the user added my app as a tab.
Does add.php send it back in a post parameter? Or how?
For those of you still having problems with the eternal refresh issue with this app add this
header('P3P: CP="CAO PSA OUR"'); ob_start();to the top of your index.php so first three lines should look like this.
<?php header('P3P: CP="CAO PSA OUR"'); ob_start(); session_start(); include_once "fbmain.php";HAVE A GREAT DAY!
Thanks for your information.
Hi, your tutorial is a great asset, and I appreciate the time you have taken.
However, I am also having the issue with constant refreshing afte user grants permissions. I have tried the header code given above, but it is still refreshing constantly.
Here is the code I am using: https://gist.github.com/1529362
Any idea? Thanks!
thank you soooooooooo much, i been trying for days to get it working on IE that piece of crap.
Really appreciated
I solved my problem. For those who have the same problem:
You can get the id of the page your application is currently loaded in like this:
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode(‘.’, $signed_request, 2);
$data = json_decode(base64_decode(strtr($payload, ‘-_’, ‘+/’)), true);
$page_data = $data['page'];
echo $page_data['id'];
Very nice work!
Just one thing…after user allows app permission, I keep getting a blank page after redirect. Can you help?
oops my bad…fixed it…didnt have correct url set in fbconfig…
great work!
Hi Mahmud,
I am experiencing the eternal refresh issue in IE.
I have tried
header(‘P3P:CP=”IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT”‘);
and
header(‘P3P: CP=”CAO PSA OUR”‘); ob_start();
but neither appears to work.
Hello Mahmud,
where is cancel_url variable, in the new sdk 3.0? What is the replacement?
I don’t see any cancel_url type parameter in the sdk 3.0 library.
Mahmud!
I can’t thank you enough for your sample code!!!!
You’re AMAZING!!!
I wanted to know if you knew how to do the following
(because I desperately need to know how to do it)
I’ve seen apps like this one (http://www.facebook.com/add.php?api_key=11883d2755547ed0ce4d7adf4b417bd5&pages)
that give the user who adds it the option to save different parameters…
Can you either #1 help me figure that out, like prompt the user to enter in a custom API key and passphrase (from my web app)
and then save that so that way on their page’s tab, it can show the right form depending on their parameters entered…?
I can send you an example app that does EVERYTHING I want mine to do…
If you don’t want to write and article but are willing to help me, I can pay you some $$$ (not a whole lot, due to not having a big budget for my simple app)
Let me know
Your ROCK!
-Tim
just let me know when you get a chance Mahmud!!
You ROCK!
Hello, Unfortunately I’m highly busy, working on iOS projects, working on my clients web project and additionally learning guitar. So I couldn’t help you in this point. :S
Hi mahmud,
first i will tell to you thanks for your help and great website.
All is working perfectly after i follow your tutorial !
Now i try to have the “auto publish stream” on the wall of the user like i have actualy with my old rest API
(when a user allow the application a “wallpost” is displayed in his own wall its automatic)
I have this with my old rest api just after the old
$user_id = $facebook->require_login($required_permissions = ‘publish_stream’);”
old api here :
$message = ‘my message here’;
$attachment = array( ‘name’ => ‘attachement here’, ‘href’ => ‘http://apps.facebook.com/myapp’,
$action_links = array( array(‘text’ => ‘message’, ‘href’ => ‘http://www.facebook.com/myapp‘)); $attachment = json_encode($attachment); $action_links = json_encode($action_links);
$facebook->api_client->stream_publish($message, $attachment, $action_links);
but i try now SDK3…dont find how to do “auto publish stream when you accept the app
I hope there is a way to do it ! Thanks you !
hi mahmud, can teach me how to save the user data after being granted permission?
http://thinkdiff.net/facebook/users-demographic-data-from-facebook/ checkout this tutorial to get idea.
Hello Mahmud,
can you tell me please how to loop the request id array after invite and save the user id in the database?
thank you
Did you solve this?
Did you solve?
Stream publishing doesn’t work. Even in your app…
checkout this link http://bugs.developers.facebook.net/show_bug.cgi?id=17801
how does “offline_access” works? I am successful at granting permission for offline access. do u have a tutorial on this. do u recommend any other site tutorial.
I found this (http://blogs.canalplan.org.uk/steve/2010/05/05/using-the-new-facebook-graph-api-off-line/)
but I thinks is Old api and SDK 2.
why can’t i print the user’s basic info? does anyone having the same problem? thanks
http://apps.facebook.com/thinkdiffdemo/ I’m seeing the basic information of user under User’s Basic Info. Have you checked that ?
hi,
on your demo, i can see my user basic info.
i downloaded your code, input my appid, secret, baseurl, appbaseurl. when i load the page, authentication runs ok. it displays my ID and session array but the basic info array is blank. am i missing something here? thanks
mahmud ahsan,
Thanks for the update for 3.0x works like a charm with the basics..
I’m trying to expand your system with useing jquery tabs and ajax to load in another php or html page into the tab.
I just use the jquery ajax tab system, which is quite easy.. you just create a li for your menu with the url for example..
test
and then on the home.php page put the empty div tag
so that works.. but on my test.php page, I cannot get any fb data anymore.. $user doesnt seem to work, it gives me an undefined variable…
this is my test.php page
api(‘/me’);
} catch (FacebookApiException $e) {
//you should use error_log($e); instead of printing the info on browser
d($e); // d is a debug function defined at the end of this file
$user = null;
}
}
?>
hello
if i add include_once “fbmain.php”; on the test page, it just refreshes the page and loads the main tab or Home page.
any thoughts on this? seemed to work fine with php 2.x sdk
I don’t know what is the problem, my demo and code is working nicely.
try the above, the issue is loading a html or php page into a tab instead of having all the html code and links in home.php
Hi, I also get a undefined error.. curl is enabled on our server.. please help
$userInfo=$facebook->api(“/$user”);
seems to be not working. am i missing something? thanks
its working for us and also in our code and demo.
it turned out that the use of CURL function in the hosting site was disabled. i had it enabled and everything is working just fine now. thanks mahmud.
The above demo apllication is not working Properly in IE8, Stream Publish Box Is not Working Properly At all
Mahmud,
I like your demo but I had a question, I didnt want to clutter my home.php page with all the code I need to write. I prefer to have tabs that load up various other php pages.. like invite.php , game.php and each one of those loaded in the jquery widget.. but im having a hard time figuring out where to start with this part.. any advice or thoughts on how to just load a simple php page in as a tab ?
yeah you can do it easily, just include fbmain.php in all your pages, and if you use javascript sdk then include javascript library code in your template page where you’ll load different page.
Mahmud,
I love this code and facebook needs to follow suit and provide better documentation. My question is this, I used your code and plugged in my own specifics and the app works fine and exactly like your demo works except for anything to do with publishing, when I try to send request/invitation, stream publish, or status update I get an error every time. with send request and click here I get an error from facebook, and then when I click ok on the error the title bar says XD Proxy and the address bar starts with
static.ak.fbcdn.net/connect/xd_proxy.php?with server generated code after that
any idea why this is happening. Do I need to install the javascript sdk too or anything for ajax or jquery. I am using wamp with apache, php, and mysql and curl extensions are enabled. As I said the app works fine, authorizes, and displays correctly and that the only problems I am having have to do with the fnctions basically. all the code is working except for the publish, streampublish and newInvite functions in the index.php file. I am stumped and any help you can provide will be eternally appreciated. Thank you in advance
Use javascript sdk and check what happens.
May be a dumb question, but you use javascript sdk the same as php correct? I mean, do I put the contents of the zip folder from github in my app directory on the server and include all.js.php?
I think I know what the problem is, since I am only having errors with any of the feeds it makes sense that it is because this sample code doesnt reflect the access token change that went into effect June 3rd. From what I am understanding from the documentation every single post is going to require the use of access token. See if what I am saying makes sense to you or if I am off on a tangent that wont help me lol
This is where I got the info
https://developers.facebook.com/blog/post/509/
Hey Mahmud,
Great work on this API, loving it, but i have some questions. For instance, when i use facebook connect on other pages, the page remembers my login, but your script doesnt seem to, is this intentionally or is this an error?
When facebook will update their javascript SDK I think then this problem will solve.
Hi,
I try to add to index.html code
of reading events from user($user) and when I run the app event I got err
“Fatal error: Call to a member function events_get() on a non-object in /home5/centerwo/public_html/facebook/template.php on line 142″
my code:
$events = $facebook->api_client->events_get($user, null, $start_time, $end_time);
print_r($events);
………
what I miss here ?
Thx
Hello Mahmud,
can you add code of creating and reading event please
thank you
Actually its very easy, http://thinkdiff.net/facebook/essential-graph-api-of-facebook/ check points 6. But as facebook recently updates their php sdk so you may have to update this code.
I check
Thx
Hello Mahmud,
Thanks for your help
I like your demo ,Great tutorial!!
When I try to build code event and integreted with
Your demo.
acording to your link ,
http://thinkdiff.net/facebook/essential-graph-api-of-facebook/.
I have some difficult and err
I want to select from the dialog invite friends and send Them event.
Plese can help
thank you
Hi Mahmud!
Great tutorial!!
I have one question. I use your tutorial but when an user clicks on “Don’t Allow” it keeps redirecting to the permissions page, how can I redirect to home page when that happens?
Thank you so much
Just adding to the loginUrl “‘redirect_uri’ => ‘myapp’” it works. Thanks and keep up the great work
Thanx a lot mahmood vai for your excellent tutorial. It helps me a lot for building the FB application. One query, is it possible to send email using facebook application??
I can collect the email address, but is it possible without collecting??
No, it was possible during 2008-2009, but now that is not possible. You’ve to use your own mailing system to send mail. If you use php you can use mail() function for that.
i am using your graph api i want to know how to get user mobile number using graph api. 2nd thing i change code to work in code igniter i faced one problem the graph api is working at localhost but donot work on my testing server.
after login i run the following code in register view but register view donot work properly please guide me i am very tahnkfull to you
here is the following code
<?php
$fbconfig['appid'] = "appid here";
$fbconfig['api'] = "api key";
$fbconfig['secret'] = "secrete";
try {
include_once "facebook.php";
} catch (Exception $o) {
// echo '’;
// print_r($o);
// echo ”;
}
// Create our Application instance.
$facebook = new Facebook(array (
‘appId’ => $fbconfig['appid'],
‘secret’ => $fbconfig['secret'],
‘cookie’ => true,
));
// We may or may not have this data based on a $_GET or $_COOKIE based session.
// If we get a session here, it means we found a correctly signed session using
// the Application Secret only Facebook and the Application know. We dont know
// if it is still valid until we make an API call using the session. A session
// can become invalid if it has already expired (should not be getting the
// session back in this case) or if the user logged out of Facebook.
$session = $facebook->getSession();
$fbme = null;
// Session based graph API call.
if ($session) {
try {
$uid = $facebook->getUser();
$fbme = $facebook->api(‘/me’);
} catch (FacebookApiException $e) {
// d($e);

How can I deny direct access to the application sitting on the server (http://domain.com/theapp/)? I want my application to be accessible only through facebook and without the use of Javascript redirect.
Thanks Mahmud for the tutorial! Great info that can all be found in one place – very helpful.
Unfortunately I seem to be experiencing some issues in IE7:
- the “publishStream” function doesn’t execute when used in “onClick” on an anchor link… same with “newInvite” function
- jQuery form validation doesn’t work
These issues are only happening on IE7, but it works great in all new browsers (including IE8).
Does this mean the jQuery is having issues with IE7? I’m stuck. Can anyone help me understand what the issues are?
IE sucks, I am sorry as I do not know what is the reason for IE7.
While I completely agree with you, we can’t ignore the reality that people are still using old browsers.
I found a solution:
Use Custom Channel URL
1.Add channelUrl parameter in FB.init session.
FB.init({
appId : ‘YOUR APP ID’,
status : true,
cookie : true,
xfbml : true,
channelUrl: “http://yourdomainname/fbtest/channel.html” //Add this file in your website.
});
2.The contents of the channel.html file should be this single line:
3.Test your FB login…Enjoy…
Reference URL:
http://developers.facebook.com/docs/reference/javascript/FB.init/
sorry, the line for “custom.html” should be:
(script src=”http://connect.facebook.net/en_US/all.js”)(/script)
replace () with
hi Mahmud,
First of all thanks for the tutorials.
Im working on real-time update.
I get this Error:
OAuthException: Invalid OAuth access token signature.
This is how i get my access-Token:
$my_access_token = file_get_contents(‘https://graph.facebook.com/oauth/access_token?client_id=’.$facebook->getAppId().’
&client_secret=’.$facebook->getApiSecret().’
&grant_type=client_credentials’);
Is this the wrong access-token ?
thanks
hi again..
i solve the problem . i forgot to add this :
$access_token = str_replace(‘access_token=’, ”, $my_access_token);
But now i get this Error:
OAuthException: (#2200) callback verification failed: connect() timed out.
It seems that the FB-Server can’t connect to my server.
Is it because im working on localhost and using DynDNS ?
bye
I have a question. Why do you have to make $userInfo, can’t we just use $user_profile instead?
@ mahmud ahsan
I don’t want user authentication popup every time. I have an email and password. So i want to get session value by simply passing it through. Any Idea how can i do this ?
Thanks in advance,
Kashif
I read your post it’s an awesome dude ! I always come back visit your blog time to time.
Thanks !
Hello and thank you for helping me thinking diff
I have some questions about the invite stuff and the tracking this is my scenario:
I have several function newInvite (newInvite2, etc..) inside my aplication each one have a custom message and the user can invite their friends and everything is working fine.
Now is it possible to show that user what invites he send to what friends? and witch ones were acepted?
and wend a invited user lands my app how can he see what were the invites that his friends send him?
I can’t seam to wrap my head around the developers.facebook docs.
Ok now i’m able to retrieve all app requests for a visiting user
$request_url =”https://graph.facebook.com/” .
$user_id .
“/apprequests?” .
$access_token;
$requests = file_get_contents($request_url);
echo ”;
print_r($requests);
echo ”;
But how can I show to the user who and how manny invites were accepted by his friends?
Hi, Mahmud you’re our hero!
I have a question regarding the form submission. In SDK 2.x when submitting a form to my URL I got the $user_id with
$user_id = $facebook->getUser();
but now it returns 0. I don’t like the idea of passing the user_id as a form parameter. Any suggestions?
Hi
I want to get information about the Invite button for a page. Now the FB.ui(method:’apprequests’) sends the application request. while the user click on it, it shows a page to install the same.
If I want to invite to a page of mine, hows it can be possible from iframe
Hi; thank you for a greate post.
I downloaded and installed your sample. each time the application is loaded i am redirected to my website and the not the iframe page.
next time application is accessed that sample is loaded correctly.
not only is there a redirection but with a paramater names code and its value, like this:
http://www.activ8.co.il/?code=RxE2vl3Ka551v3aJYcJkiiBjxV7pyUhl2fkAI_YENxs
is this supposed to happen?
redirect_uri
Mahmood Thanx a lot .really a great tutorial.
But I am beginner.so please tell me where should i upload the code?
where should i host my code as facebook is not hosting the code?
i want to make an app for fun so where i can host cheaply?please suggest me .
A big big thanx in advance
Mahmood Thanx a lot .really a great tutorial.
I have downloaded your code, but after I uploaded and I have adjusted as the Application ID, API Key, App secret and other parameters, when I run my application, my application continually redirect to that page.
When I checked, the script in my application:
$ session = $ facebook-> getSession ();
not running and not generating value.
my url application : http://apps.facebook.com/nokia_bobrok/
Can you help me.
thanks
You may have downloaded the old version. In the new one there is no $facebook->getSession() but instead $user = $facebook->getUser();
Go through the tutorial again and check you have everything in place.
tutorial is great ..
but the problem with my app is that ,when i played it for the first time it doesnot post to my wall THAT I HAVE STARTED USING THING THE APPLICATION…it post when i play the app more than 2 times ..
and i have not submitted my app in app directory ..
.
so how can i recitfy that problem …
Thanks for this help….
Hi its possible redirect to some url after invite friends?
exactly when you push “send reguests” thanx a lot!
your website is fantastic. But I still have some problems when I try to load another page after I pass an album id while I want to get the photo in that album. It seems like I haven’t authorized the app but actually I did because in my index page I can get user album data.
I have tried to offline_access extended permission but it’s useless. and I also tried add your fbmain.php into my page but it reloaded again and again and after that it redirects to index.php
Any idea about this?
And I wonder whether FB app support local session?
Thanks in advance
Hi, A good tutorial but I need your help
I am new in Facebook Apps development but a bit skilled in PHP-based web application.
I am deveopping a PHP Mysql voting system that allows users to choose from options. I have developped this app and made it as Facebook App.
Here I need help to improve it to fit my needs.
My First question is :
Is it possible to use the FB connected condition to make the fisrt page of the app visible only to fans of the page in
which I am using the app ?
My second question :
Is it possible to store some of the User’s Basic Info into my database ( id, email, hometown … ) because they will be
needed to classify the voting results ans to send them to people who have voted by their email.
Thanks in advance
Yeah both are possible.
for first question, when user login via facebook in your site, just grab user’s ID and using FQL query check if user is fan of your page or not. And based on the result show him what you wanted.
And for second question, you can follow my this article http://thinkdiff.net/facebook/users-demographic-data-from-facebook/ (this is based on facebook Sdk 2.0)
Thanks a lot for your answer it is very helpful. Please can I discuss with you directly through Skype or msn or FB. This is my Skype nizar.b78
msn : khomsa.arts @ gmail.com and the same address for FB
Hello mahmud,
I am facing a problem.
when i use this
https://graph.facebook.com/me/albums?access_token=XXXXXXXXXX
it return the information of all the albums. and album id as “257536820926628″
but when i use “id” return from above to show cover photo in this passion
https://graph.facebook.com/“.$ret[$i]['cover_photo'].”?access_token={$access_token}
it return some strange number instead of id like 2.57536930927E+14
firebug says that for above id it gives
https://graph.facebook.com/2.5753693092 … XXXXXXXXXX
also sometimes hardly 10% it works fine
I am wondering what is this problem. is this problem problem due to max integer length ? or anything else ?
Let me know if you ever face this problem or have solution to this problem
thanks in advance

Hello, first of all thanks, this is a very comprehensive bit of code. I have a slight issure though that is driving me crazy. When I use the PHP header() function, I get a headers already sent error. I have stripped all of the cosmetics out of the body tag and just literally have 2 blank pages, header1.php and header2.php. I have header(“Location: header2.php”); within header1.php and I still get the error. Is there something I’m overlooking? Many thanks, Mk

Hi,
i have used your code, I changed the app ID, secret, Base URL and Canvas URL, everything is fine except the app doesn’t ask for user authorization.
i have changed nothing else in code, i don’t know why i am facing this problem.
Hey Ahsan,
I used your original tutorial to get an app up and working on facebook about a year ago. Then it stopped working with the Facebook change to SDK 3.0 and I haven’t been able to get it working since the change. I had no problems with the original tutorial, but here the call to create a new facebook object where you include the appID and secret never returns an object with the userID, even when logged in to Facebook. So obviously everything else fails. Does anyone have any ideas? I’ve been running into this for over a month now with no success.

Hi Mahmud,
If a user allows my fb connect in which i asked permission to get “others people info” (for example friends_birthday,friends_group) how can I see this information. I can only see the person signing in info.
Thank you and congratulations for this wonderful blog!
@nd3r
You’ve to pass the permissions to get this info during login url, and using FQL or other graph api call you could grab the info.
Hi, check your tutorial and it seemed to work.
Thnx for that! It is the first tutorial that did work.
But i have one question that remains:
What should i do if a user does not allow my app?
You’ve to do nothing.
how to change title, in share facebook title no like my project
hey there,
Mahmud, thanks for this tutorial!
But I did have some problems getting it to work, got in an infinit loop (whie getUser always returned 0), but eventually found the solution:
instaed of using the $fbconfig object that holds the appid and secret in this piece of code:
$facebook = new Facebook(array(
‘appId’ => $fbconfig['appid'],
‘secret’ => $fbconfig['secret'],
‘cookie’ => true
));
I insert them directly:
$facebook = new Facebook(array(
‘appId’ => “1179423423478468305817″,
‘secret’ => “db16218e9fc24234234ea05c6e4f9acfa1cd81″,
‘cookie’ => true
));
And then it worked!
very strange, but maybe it helps some people here….
Or maybe someone even knows why this works?
Wouter
There is a array defined by $fbconfig where you’ve to provide the app_id, secret, baseUrl and appBaseUrl. You missed that or entered wrong information.
$fbconfig['appid' ] = ""; $fbconfig['secret'] = ""; $fbconfig['baseUrl'] = "";// "http://thinkdiff.net/demo/newfbconnect1/iframe/sdk3"; $fbconfig['appBaseUrl'] = "";// "http://apps.facebook.com/thinkdiffdemo";According to this code https://github.com/mahmudahsan/Graph-API—IFrame-Base-Facebook-Application-Development-PHP-SDK-3.0–Source/blob/master/fbmain.php
Mahmud,
Your tutorials have been a great help. My first app just required the user authorization/login stuff but now I’m working on a variation of a gift app.
I’ve been looking at the php-sdk docs and other examples and I can’t seem to discover the current methods for passing variables from an HTML form to the app.
e.g. A user writes a message in a textarea, chooses an item with form radio buttons, and then chooses the friend(s) to send it to.
How are the text area and item choices sent along with the user id for the request? Trying to solve this piece of the puzzle is one of the biggest hurdles to moving forward with my app.
Thanks for any advice.
In the demo http://apps.facebook.com/thinkdiffdemo/ there is a tab Status Update where is a text field is located. And here I am using ajax to pass data from front end to php backend. If you don’t want to use ajax then write php code to process the form. That’s easy. Mention the action parameter of the form tag and also you should use Method as “POST”
Thanks, Mahmud.
I guess where I’m getting stuck is in creating a page that combines an html form with a friend-selector.
If I have:
…my form choices
Which type of friend-selector should I call after it? And does hitting “send request” on the friend selector create a POST action for the form?
That’s my main stumbling point. I just haven’t found anything in FB’s docs that show me how to do this.
I appreciate your insight!
hmmm…don’t know how to get code to show up in your comments but “…my form choices” was wrapped in form action=”" tags.
First of all i would you like you thank you about this grate article. but i cant understand how “invite your friends” install in to fanpage.Can you please help me mahmud ahsan
Thanks
Hi! Thank you so much for this tutorial! Looks and works great! Congrats!
I have a concern. On October 1 Facebook requires Secure Canvas URL (HTTPS).
I´m a PHP Developer and I dont have experience with HTTPS. So, my doubt is:
I have to change some PHP code for this to work? Or is a server side issue?
I would greatly appreciate your help.
Thanks! (And sorry for my bad english)

Great piece. I have followed along and everything is working fine. I have a question, will all of this work with the new signed request required on October 1st. I am new to this, so wondered if the code will still work ?

Hi mahmud ahsan
Thanks for tour : http://thinkdiff.net/facebook/graph-api-iframe-base-facebook-application-development-php-sdk-3-0/
i like feature : 6. How to request/invite your friends and track them
User received invite , he is click to and allow finaly redirect to iframe ( inside app facebook) . I don’t like redirect to inside facebook , i like redirect outside , example : redirect to my site.
Do you have solution for me?
Thanks.
In that case you can provide extra parameter to detect user’s click and then you can manually redirect your user to your site.
Hello Mahmud,
THank you for your great tuts! I’m trying to use your script but there’s a problem getting user id.
I’ve added
if (!$user) {
exit(‘No user ID’);
}
just after $user = $facebook->getUser();
and the output is “No user ID”
Could that be a problem with the application settings?
Thanks
Hi Mamud,
This tutorial is very helpful… But I’ve got a problem with Google Chrome. Your demo link when opened with Google Chrome results an error:

This error also appears when I open my application. Do you have a solution for this?
Brilliant tutorial!! I just have a quick question…

I would be a great pleasure to get help from You
regards:
I want to share a link on my wall and my friends wall.I have used this code
$ret_obj = $this->facebook->api(‘/me/feed’, ‘POST’,
array(
‘link’ => ‘http://www.mysite.com’,
‘message’ => ‘Friendly Songs….!’
));
echo ‘Post ID: ‘ . $ret_obj['id'] . ”;
The link is successfully sharing on my wall.But it is not showing on my friends news feed.In facebook document they mention that because of link parameter it is not updating on friends feed.Is any other way to do this .
Thank you! I have struggled for 2 days to get PHP SDK and Auth working, maybe with out of date tutorials. It seems Facebook has changed everything twice since I was last trying to develop an app for it.
I have got it working now using your files, so I can use it to get mine running now.
Thanks again.
I have searched a bunch of misleading and outdated sources just to get the authentication to work properly. And your code worked!! Thanks !!
Hello,what i need to do to enable auto stream publis?
Can someone explain me and write that part of code?
Hello,
I followed your codes and both old and new tutorial. And it will prompt the user to log in and allow. But how do I add the publish button and invite in my game? And where does the codes store the user’s data? Please help me. Its urgent.
you should open the page home.php i guess…. there you can choose the operation to test
I have a problem to get this app working…
the first page to open is index.php, that call fbmain to check authorization and login, right?
I don’t understand the “baseUrl” and “appBaseUrl”. Shouldn’t them be the same? index.php?
I can’t start the application..

I added my app_id and app secret id..
2 problems:
__________
1 –
I tested out the demo on my server… once i click login to facebook.. it pops up to accept application and permite secure info for the app..that`s great.. but as soon as it refreshes back .. it says “Error establishing a database connection”. Why does that appear?
2 – If a refresh the page even after it appears “Error establishing a database connection” everything appears great!! So when i go to Invite friends… the popup appears..i check my friends and click on invite.. nothing else happens… none of them receive an invite to the app..what could i be doing wrong?
Here is the URL that im testing: http://www.thomasmoraes.com.br/teste

Hi Mahmud
Firt thank you veryy much for this and others amazing posts you do like many others say god bless you!
I would like to know if you can help me with some problem, i´m develping an app and it´s a page no on canvas, i install your code and work perfect to get the authorization of the user but i can´t make your on the facebook page the code that verify if user likes or not and redirect to different content or pages
It work if i don´t use the new sdk but i dont get the permision of the user and when invite friends the user on save is 0.
This is the code…
$signed_request = $facebook->getSignedRequest();
$like_status = $signed_request["page"]["liked"];
I redirect to this page (in page tab) after login (in cavas)
I don´t know if this is the best prectice, this app is very simple
1. Log + get permision to be able to save uid
2. Check if user already like the page and make redirection depending on case
3. Invite friends and save on db the request
4. Redirect to page you are done
Very sorry boring you but my boss wants to kill me and i´m new into this
Thank you very much
Best Regards

Wow that was unusual. I just wrote an very long comment but after I clicked

writing all that over again. Anyhow, just wanted to say wonderful blog!
I’m not that much of a internet reader to be honest but your blogs really nice, keep it up!
I’ll go ahead and bookmark your website to come back later on. Many thanks
Wonderful work! This is the kind of info that are meant to be shared across the internet.
Disgrace on the seek engines for now not positioning this
submit higher! Come on over and discuss with my web site .
Thank you =)
Thanks for all you work and thoughful comments.
However, there’s something I don’t understand. There are lots of people here saying that some parts of their apps are working or not working, while I cannot even get a valid user.
I did log and get the permissions, but then I get this zero user and the app starts bouncing from my server to Facebook and vice-versa.
I haven’t made any changes to your code, apart from the app credentials and url addresses. Why am I unable to get a valid user?
Might it be something on my server?
Any help would be very welcome, because I’m going mad.
