5 Steps to publish on a facebook wall using php

November 1, 2009
Filed under: FaceBook Integration, Featured, PHP 

Since Facebook has stopped supporting Java we need to use PHP for now to post on a wall.

According to facebook Wiki posting on a  wall is very confusing and very difficult to write a program to publish on a wall.

I spent around 2 weeks reading many articles and many documents, Wiki on facebook but in vein and tried many ways and finally I got one workable model. Below are 5 simple steps to publish on a Facebook wall.

Step1: Login to Facebook to Create a Facebook App

First login to Facebook and goto the url http://www.facebook.com/developers/ then

Click on “+ Set Up New Application” button to start creating the application as shown below.

Create New Facebook application

Provide the application name, click agree for facebook terms and click on “Create Application” button.

Fill in application Name

create app step1

Now Application is created for you. Just copy the Application API Key, Application Secret and Application ID details which will be used to write the application code.

Fill the Name and Description of your application in About Link.

Facebook Application About Page

Now Click on Website Link to get API Key

Facebook Application web Site

Now goto Facebook Integration link and enter any url. Here is where you will get Secret Key.

Enter the Canvas URL and page name. This will be the return URL of your Application.

Facebook Application Facebook Integration

That’s it You now just successfully create a Facebook Application, now lets work on program

Then click on Save. That’s it we have created a facebook application with an Iframe.

Now Copy Application API Key, Application Secret and Application ID details which will be used to write the application code.

Now download the php library from facebook “http://blog.theunical.com/wp-content/uploads/2010/05/facebook-platform.tar.gz

Step2: Generate One Time Token to generate Session key

How to generate One Time Session key:

Run below URL to get temporary token for the particular user by logging into Facebook.


Note: Please replace “API_KEY” with your application API key from above page.

Then we will get a temporary token key.


generatemylogin info


This is one time token key that we can use to generate a permanent session key. Careful! Don’t try to execute this programs many times

Step3: Generate one time session key (permanent session key)

Below is the sample PHP code to generate one time session key.


// FB_APIKEY is your facebook application api key

// FB_SECRET is your application secrete key



$fb = new FacebookRestClient($FB_APIKEY, $FB_SECRET);

$testtoken= "ONETIMETOKEN"; // Replace this value with your Token Value

$result = $fb->call_method('facebook.auth.getSession',

array('auth_token' => $testtoken, 'generate_session_secret' => true));

echo "<br /><pre>";


echo $session_key = $result['session_key'];



For example, the full URL for logging in a user could be:


If the user is redirected to the URL specified by the next parameter, then Facebook grants your application a session. This session is appended to the URL as a JSON-decodable object of the form:

&session={“session_key”:”SESSIONKEY”, “uid”:USERID, “expires”:0 || UNIXTIME, “secret”:”SESSIONSECRET”}

In continuing with the above example, the redirect for a successful login would be:


If the user grants your application the offline_access extended permission, 0 gets returned for expires and the session never expires unless the user removes the application. In this case, you should store the session key so the user doesn’t have to log in the next time he or she launches your application.

Note: The above code will execute only once. We should note down the above session key, This will be used to auto login into the application.

If you don’t save these session key values you should generate other token key to create one time session key.

We can use the token only once.

Step4: Setting Permission for wall

Giving Permission to your application to publish on facebook wall. To give permission just replace the your API key in below URL and execute in browser.


Then you must see the below 3 Screens

If you don’t see the below then your call back URL or Canvas URL must be incorrect, please check again your application settings and execute the URL again.



Then on final page, you will see a success message.  That’s it you have given permission for read_stream,publish_stream and offline_access.

Step5: Publishing the message on Facebook Wall

PHP Code to create facebook object with onetime session key and publishing the message on Facebook Wall.




define('FB_SESSION', 'YOUR_SESSION_key');


echo "post on wall";

try {

$facebook = new Facebook(FB_APIKEY, FB_SECRET);

$facebook->api_client->session_key = FB_SESSION;

$fetch = array('friends' =>

array('pattern' => '.*',

'query' => "select uid2 from friend where uid1={$user}"));

echo $facebook->api_client->admin_setAppProperties(array('preload_fql' => json_encode($fetch)));

$message = 'From My App: publish steven on facebook';

if( $facebook->api_client->stream_publish($message))

echo "Added on FB Wall";

} catch(Exception $e) {

echo $e . "<br />";



Now you will see the post on wall Great.

published on facebook

So thrilling isn’t we can also publish photos videos on wall.

In my next post see how to publish images and videos to facebook is done

have a great day

  24. HI steven,
    I have admin section on my website. I am updating news content on website daily. I want to publish same content on my facebook account wall. What I want is when I submit content in my websites’s admin area, it should also update facebook wall with same contents.

    I have set up facebook application and grab the API Key and other required information. I am using iframe and not fbml.

    I am using stream_publish() function.

    Problem is here when I submit data using stream_publish, it redirects me to login page.

    Is there any method through which I can login to facebook and publish content to my facebook wall.

    Below is the code.
    $user = $facebook->require_login();
    $attachment = array(‘name’ => $name, ‘href’ => $link, ‘description’ => $description, ‘media’ => array(array(‘type’ => ‘image’, ‘src’ => $imagelink, ‘href’ => $link)));
    $action_links = array(array(‘text’ => $name, ‘href’ => $link));
    $attachment = json_encode($attachment);
    $action_links = json_encode($action_links);

    Please help.

    Thanks in advance.

  25. Steven Robert on Mon, 4th Jan 2010 9:47 pm
  26. Hello Vishal,
    You need to complete Step 2, 3, 4 to create a one time session key and give permission to publish on wall. so that next time it will not ask you to login to facebook.
    Let me know if you done these correctly.

  27. Vishal on Mon, 11th Jan 2010 6:41 am
  28. Hello

    I tried to perform all steps mentioned below.
    1) I have created application as mentioned.
    2) I have retrived one time session key.
    3) I have granted permission as well.
    4) In application setting, I have canvas call back url, this would call the script in step 5.

    Now what I do is I logged out from facebook. Then I typed url in address bar as http://apps.facebook.com/theunicalblogtest/

    This shows me “Sign up for Facebook to use Blog TheUnical.”

    What I am doning wrong here? can you please let me know here?

  29. Steven Robert on Mon, 11th Jan 2010 10:53 pm
  30. Hi Vishal,
    Why you want to type this URL “http://apps.facebook.com/theunicalblogtest/”. you can just execute your program.

  31. Tomee on Fri, 15th Jan 2010 3:37 am
  32. Hi there,
    the code from the step 3 where should be copied to run, ‘couse saving to a file and just run it does not gives you a valid response.

  33. Steven Robert on Fri, 15th Jan 2010 10:56 pm
  34. Just Copy the php code and replace with your keys and execute to generate a one time session key. Tomee, you need to execute this only once, if you try to execute this 2nd time you will get some errors.

  35. Steven Robert on Fri, 15th Jan 2010 10:58 pm
  36. Tomee, If you get errors then try again from step2.

  37. Tomee on Sat, 16th Jan 2010 9:00 am
  38. i obtained the one time code Steven, and the API code and secret also. When I run the file it gives me the “FacebookRestClient” undefined function error, which is kinda normal I think ‘couse it is nowhere defined in the php file.

  39. Steven Robert on Mon, 18th Jan 2010 12:44 am
  40. Hi Tomee here is the same code that is working for my id , replace with your’s and try. http://blog.theunical.com/?attachment_id=267142.
    let me know if you still have any issues.

  41. shyam on Tue, 19th Jan 2010 9:20 am
  42. I follow the instruction but i have a problem when i am trying to generate session since there is class page in not included in STEP 3 so firstly is say class not found and even after adding the related class now is saying

    Class ‘Facebook’ not found in /var/vhosts/apartmentsneakpeeks/httpdocs/facebook-platform/php/facebookapi_php5_restlib.php on line 82

    Rest was fine but in the last due to session value is “” i could not make the post done.

    Will you please mail me regarding this.
    Thanks and Regards,

  43. Steven Robert on Wed, 20th Jan 2010 4:32 am
  44. Shyam did you tried downloading the code from here? http://blog.theunical.com/?attachment_id=267142

  45. Steven Robert on Wed, 20th Jan 2010 4:33 am
  46. Shyam did you tried downloading the code from here?

  47. Maria on Thu, 21st Jan 2010 7:37 pm
  48. Steven, I cannot execute step 3. Is the php code supposed to be executed on a server? I have plugged in my values, but I get php parsing errors.

  49. Maria on Thu, 21st Jan 2010 7:40 pm
  50. Plus, line 11 in step 3 should be:

    $fb = new FacebookRestClient($FB_APIKEY, $FB_SECRET);

    FB_APIKEY and FB_SECRET are php variables. And should the code not include the facebook php library? I am very confused.

  51. Maria on Thu, 21st Jan 2010 7:54 pm
  52. And finally, this link does not show any code :(


  53. Steven Robert on Thu, 21st Jan 2010 10:50 pm
  54. There is a link that you can download from, check again.
    This is that link http://blog.theunical.com/wp-content/uploads/2010/01/fb_app.zip

  55. Steven Robert on Thu, 21st Jan 2010 10:51 pm
  56. Maria, This should be replaced by facebook secret key and facebook app key

  57. Steven Robert on Thu, 21st Jan 2010 10:53 pm
  58. Yes Maria, the code should be executed on server.

  59. Tomee on Fri, 22nd Jan 2010 11:16 am
  60. Thank you steven I managed to publish on my wall finally :) can you help in making publish possible from my app ?

  61. Steven Robert on Fri, 22nd Jan 2010 10:52 pm
  62. Hi Tomee, You can just create a Iframe of your existing application and try it in Facebook App.

  63. Tomee on Sat, 23rd Jan 2010 6:49 am
  64. Steven what I would like to do is, anyone who uses my facebook app and clicks on a link to be able to publish on his own wall a message like “come and play this” or that game :) I was looking on the facebook dev forums but it’s a mess majority of the examples are using deprecated functions, and no working example can be found :( disappointing

  65. Steven Robert on Sat, 23rd Jan 2010 10:56 pm
  66. Tomee, To Publish on Users you need to first generate a one time session key and later they need to give authentication, so that you can publish on their wall.

  67. Fabio on Mon, 25th Jan 2010 11:08 pm
  68. Hi,
    i’m enchanted … wow , your article “5 Steps to publish on a facebook wall using php” is the unique resurce that explane how to publish on Facebook wall without use form login.
    I googled a lot and fortunately i found your blog.
    But i’m also curious,so i would ask you :
    1. How did you find this solution? and all the links used to open a session? On developer Facebook section i could not find nothing about. Are maybe secret links ? 😉
    2. And, is possible to publish on a Fan-page wall instead of User wall ? If yes, how can i customize it?
    Thanks a lot.
    Bye from Italy


  69. Steven Robert on Mon, 25th Jan 2010 11:10 pm
  70. Hi Fabio,
    Even I too have to do some research like you when I got requirement to publish on a wall and I tried a lot at last I was successful to publish on wall. So I thought, since there are no post that truly describes how to publish on a wall. So I have to write this post. The solution is in facebook but not on a single page you need to read some 20- 40 pages and try lot of examples then you will get.
    Yes, you can publish on Fan-page too, but you need to get permissions of that page too.
    – Steven

  71. Fabio on Tue, 26th Jan 2010 7:32 am
  72. Good…i have permission…i’m administrator of the Fan Page.
    Can you give me some php code suggestion?

  73. Steven Robert on Tue, 26th Jan 2010 10:11 am
  74. Hi Fabio,
    Here is the example PHP code and the screenshots in my next post to publish on a Facebook fan’s page.
    If you still have any difficulties we can develop any facebook applications for you.

  75. shyam on Thu, 28th Jan 2010 5:52 am
  76. Hello Steven Robert,

    Thanks for reply, thanks for write such page to helps other.
    Perhaps i was wrong some where now i can post without log in.
    Will you please tell me how to add image /url along with the post and what are the purpose of this line ?
    “‘query’ => “select uid2 from friend where uid1={$user}”));”
    is this related to our table or FB’s table.
    Thank you in advance and waiting for your reply.
    I was late to write this because i could not test the application after your message.
    Today i did .


  77. Steven Robert on Thu, 28th Jan 2010 9:59 pm
  78. Hi Shyam, That is a facebook table.
    In my next post see how to publish images and videos to facebook is done



  79. shyam on Fri, 29th Jan 2010 1:15 am

  81. faemino on Fri, 29th Jan 2010 8:31 am
  82. Just thanks for all your articles about Facebok conection from PHP. Great resource and nice job. :-)

  83. Maria on Fri, 29th Jan 2010 3:24 pm
  84. Steven, I tried all of your code for step 3, and I cannot get it to work …. grrrrrr!!! I download the php library from facebook to my server. I copy the generatesession.key.php to the same directory on my server and name it index.php. Then I try to call my application from Facebook, but I get error message. What am I doing wrong?

  85. Steven Robert on Fri, 29th Jan 2010 9:58 pm
  86. Hi Maria,
    Did you created the facebook application, as I described in Step1? Iam able to publish with a new account in 10 mins. May be you are doing something incorrect.
    Also please make sure that you enter any working URL in Canvas call back URL and Connect URL. if this is missing then the application will not work.

  87. Rangga on Sat, 30th Jan 2010 7:24 am
  88. I have 2 questions as below:

    1. What is the real purpose of fetching friend list on your code, since I didn’t see any relation with it main topics; to put something on our wall.

    2. Is there something that need to change from your code if I want to implement it on my mobile web ?

    Thx 4 sharing..

  89. Jim on Sat, 30th Jan 2010 3:48 pm
  90. Thank you! After many days of search, google’ing and testing this page was the key to posting messages to an offline user

  91. Steven Robert on Sat, 30th Jan 2010 11:16 pm
  92. Rangga, this code work’s perfect on mobile web too.

  93. fede on Mon, 1st Feb 2010 2:58 pm
  94. genius you save my week work, the documentation of facebook is a bullshit and you explain us so clear and concise.
    Thank you very much.
    Fede from rosario,argentina.

  95. Sebastien on Wed, 3rd Feb 2010 10:09 am
  96. Thank you so much for this code. I have been reading the facebook wiki for days trying to achieve this and they’ve managed to confuse me beyond belief. I was able to connect thanks to you!

    I do have one question though, is the one-time code a link between the application and the facebook account? If I give my users the ability to post on their walls from my website can I use the token (assuming I save it somewhere and get their permission) indefinitely? I’m trying to figure out if the session key will expire.

    Thanks again!

  97. Steven Robert on Wed, 3rd Feb 2010 9:57 pm
  98. Sebastien , do you want to post users on your wall. If so, you can create a simple app and give to your users. If the users has to post on their own wall then you can simply use any bookmarking tool like Shareit, Addit etc.

  99. Aziz on Thu, 4th Feb 2010 9:33 am
  100. I am stuck on step 3. I am assignning the apikey, secret and token, but when i run it i am not receiving the session key.

  101. Kapil Jadhav on Fri, 5th Feb 2010 9:10 am
  102. Hi Thank you for the code and description. The steps and code work like charm. I am successful implementing this but just wanted to know if there is a way to ask user ib a popup if they want to publish or skip.

    Thank you a tons,

  103. Aziz on Mon, 8th Feb 2010 6:07 am
  104. Ohh i am so stupid ))) Thx it worked. this method is great!!

  108. hi Steven

    I have write message on my application wall

    Your coding is used to message display on user wall

    have u help me …??

    thanks in advance

  109. TheTester on Fri, 19th Feb 2010 7:16 am
  110. Great tutorial but I have one question. What if want to make not temporary session key but something to call stream.publish in background(for example as a cron job). In such scenario I can’t ask user for session key so I need some kind of persistent session key. How can I obtain it?

  111. Steven Robert on Fri, 26th Feb 2010 12:22 am
  112. hello TheTester, Do u want to publish on user own wall, if yes then there in no need of any session key, you can just any bookmarking tool for this, like I used one in this blog.

  113. Sylvester Faro on Thu, 4th Mar 2010 6:48 am
  114. This is GREAT… after wasting hours on <> Facebook API docs, I got this working in less than 5 minutes.

    Like “TheTester”, I will be using this on a Cron Job to publish on my own wall… I have same concerns for “how long will the session key be valid?”… But I guess I will have to monitor “invalid session key” publishing errors and then generate a new session key…

  115. Steven Robert on Thu, 4th Mar 2010 9:52 pm
  116. Hi Faro, The session key will be valid until something unusual happens, Like if you hit facebook continuously , like in 1min you tried to hit some 50 times then that key will be invalid then you need to generate again a new key. If not then it will be valid for a longer time.

  117. abrahan on Mon, 8th Mar 2010 8:33 pm
  118. Hey!, when i try 2 and 3 steps, i get this error:

    Canvas Callback URL must point to a directory (i.e., end with a “/”) or a dynamic page (i.e., have a “?” somewhere).
    Connect URL must point to a directory (i.e., end with a “/”) or a dynamic page (i.e., have a “?” somewhere).

    do you know why appears the error? and… can you help me to solve it?

  119. Steven Robert on Mon, 8th Mar 2010 10:45 pm
  120. Hi Abrahan, This Canvas URL and connect URL should be a publicly accessible URL.

  124. its a very nice post, but i am unable to get 100% out of it. Can you let me know where the code generated by user as permanent code for my site need to be used.

    ‘Session key invalid or no longer valid’
    please guide me where i am doing the wrong implementation
    any kind of fast help will be very thankful


  125. Steven Robert on Tue, 16th Mar 2010 9:01 am
  126. Hi Navjot, After you execute Step3: Generate one time session key , on your browser you can see a session key printed. This is what the Permanent session key. This key will be in two parts separated by a hi-fen. Let me know if you still have any issues.

  127. Dinesh on Tue, 16th Mar 2010 9:36 am
  128. Hi Steven,
    Pls help me

  129. Steven Robert on Tue, 16th Mar 2010 10:04 am
  130. Dinesh The URL need to be Public Available URL and not a local URL, Check it once. Are you trying with a public URL?

  131. Sylvester Faro on Thu, 18th Mar 2010 7:13 am
  132. This code works fine in posting to my profile’s wall.
    If I setup a facebook page (http://www.facebook.com/pages/create.php), that page will have its own wall.

  134. First of all thanks for this tutorial.
    I have one question:
    I’ve made all the steps and its all working but.

    My facebook name is:
    Bruno Gomes

    My Application name is

    My Fan page is:

    When i run the script to publish to wall or the the fan page wall all goes well but it says:

    Bruno Gomes From My App: publish steven on facebook
    3 minutes ago via creative-mood · Comment · Like

    And i wanted to say:
    Creative-mood From My App: publish steven on facebook
    3 minutes ago via creative-mood · Comment · Like

    Is there any chance to do that.
    I wanted to be the application creative-mood to make the post not myself..

    Sorry for my english:
    Thanks in advance

  136. Hi Steven

    I went through all 5 steps n used the code. Guess what it worked very smoothly
    The only issue is it works only on my profile. my friend who is also using the application is not getting any messages on the Wall. Do u have any idea y?

  137. Chandan Singh on Fri, 19th Mar 2010 2:20 am
  138. hi Steven

    I did everything as per the post and it worked on my id. but if anybody other than me tries it using their id it does not post the messages on the wall. could u please explain how do i achieve this.

  139. Steven Robert on Fri, 19th Mar 2010 4:26 am
  140. Hi Sylvester Faro, Just get the pageid or fan page id or where ever you want to publish get that ID and set that in target id

  141. Steven Robert on Fri, 19th Mar 2010 4:29 am
  142. Hello Chandan, This will be published on your wall and not their wall because you can set everything from your User, and given permission to your wall.

  143. Steven Robert on Fri, 19th Mar 2010 4:51 am

  145. Thanks Steven for the fast reply.
    I Dont know python :( so i problably give up.

  147. Hi Steven. Nice post! When I run the code to generate the session key, I get a “Notice: Uninitialized string offset: 0″. I have no idea why this appears. And also, I don’t get any value back from call_method ? Why is that ?

  148. Steven Robert on Fri, 19th Mar 2010 10:59 pm
  149. Steven Robert on Fri, 19th Mar 2010 10:59 pm
  150. Ok Bruno I will write up a post for you.

  151. Nick on Wed, 24th Mar 2010 3:16 am
  152. Great tutorial, thanks steven!

    I have gotten all the way to Step 5, where it’s time to make my first wall post. Unfortunately the following error message appears:

    post on wallexception ‘FacebookRestClientException’ with message ‘This method call must be signed with the application secret (You are probably calling a secure method using a session secret)’

    Can anybody provide insight? I have verified application URLs specified, permissions granted, session key obtained, etc. Baffling. Please note that I am not very proficient in PHP I just managed to copy enough code to get it working up to step 5…

  153. Luca on Wed, 24th Mar 2010 10:16 am
  154. Hi Steven!
    as Bruno, I need to publish post on Facebook Page wall as a Page (not a user).

    Let me know when you will post the solution!!

    Thank you

  159. Sammy, what’s the error that you are getting?

  160. Steven Robert on Thu, 25th Mar 2010 12:00 pm
  161. Hello Bruno and Luca,
    I was little busy this week, I was in Sun Tech Days 2010, at last, here is the post that helps you to publish on fan page as fan user using php, Let me know if you have still any issues. http://blog.theunical.com/facebook-integration/publish-on-facebook-fan-page-as-fan-user-using-php/

  162. Saurabh on Sun, 28th Mar 2010 1:52 pm
  163. Hi Steven,

    I could not post on the wall despite following the steps given on the blog. Please help. I am using the one time session key which is generated using the token code. Also , please let me know, how will the other users who are using my app will be able to post on their walls so that their frnds will get updates ?

  164. Steven Robert on Sun, 28th Mar 2010 10:46 pm
  165. Saurabh, check all the steps and all the fields of screen shots again. It will work. Other users need to give permission to their wall or Use some bookmarking tools, so that they can publish on their walls.

  166. kirochi on Mon, 29th Mar 2010 12:10 pm
  167. This code is good

    require_once ( ‘php / facebook.php’), / / the two folders you have downloaded it mounted the server

    $ api_key = “xxxxxxxxxxxxxxxxxxxxxxxxxx”;
    $ secret_key = “xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx”;
    $ facebook = new Facebook ($ api_key, $ secret_key);
    $ user = $ facebook-> require_login ();

    $ message = ‘news http://www.mega.cl test';
    $ has_permission = $ facebook-> api_client-> users_hasAppPermission (publish_stream “);

    / / The user must give permission for your application publishes information on its wall.
    if ($ has_permission)
    $ facebook-> api_client-> stream_publish ($ message);
    echo ‘posted the message’. $ message;
    else (
    $ address = “http://www.facebook.com/connect/prompt_permissions.php?api_key =”. $ api_key. “& v = 1.0 & next = http://www.facebook.com/connect/login_success.html?xxRESULTTOKENxx&display = popup & ext_perm = read_stream, publish_stream & enable_profile_selector = 1 & profile_selector_ids = “. $ user;

    header ( “location: $ address”);

  173. Thank you so much,
    I spent so long trying to do it,
    and I could not have done this without this great guide.
    oh ye and there was a small bug i found:
    on step 3 this line is wrong:
    $fb = new FacebookRestClient(FB_APIKEY, FB_SECRET);
    and should be change to (since this parameters are not defined):
    $fb = new FacebookRestClient($FB_APIKEY, $FB_SECRET);

  210. Steven Robert on Wed, 28th Apr 2010 10:47 pm

  222. Aziz on Tue, 11th May 2010 5:48 am
  223. Steven does your library still works is everything ok? I performed all steps before and it worked but now i cant get to use the function from it. I have checked everything. When it comes for functions it stops.

  224. Steven Robert on Tue, 11th May 2010 8:19 am
  225. Aziz,
    Which function are u referring, Face book has changed some of the api settings.

  226. Aziz on Tue, 11th May 2010 9:07 am
  227. I am using

  228. Steven Robert on Tue, 11th May 2010 11:35 pm
  229. Aziz, Try download the library from above, facebook has changed its library. The methods you are using still work.

  230. Aziz on Wed, 12th May 2010 5:05 am
  231. Hmm… when i used this tutorial from begining it worked fine again and I have checked all my previous codes, they worked too. strange.. though. Anyway thank you again and for the tutorial again. I just wonder if it is possible to do the same with new api

  232. nikhil on Thu, 13th May 2010 8:10 am
  233. Hi Steven,
    Thanx for such wonderful description, its pretty easy as we go step by step.
    I was just wondering if my website can have ability to post on other user’s wall

  234. Steven Robert on Thu, 13th May 2010 8:35 am
  235. Hi Nikhil, If the user gives permission to their wall then you can publish on their wall too.

  236. nikhil on Thu, 13th May 2010 8:45 am
  237. Ya I understand that but don’t they require their API Key and all, an average user won’t even take little pain to get their Keys
    What I need is that user could post on other person’s(friends ) wall.
    Thanx for quick response

  238. Steven Robert on Thu, 13th May 2010 10:42 am
  239. No Nikhil, Your API will be sufficient, They just need to give permission to their wall.

  240. Edgar on Mon, 17th May 2010 10:06 am

    Thank you for your reply in few hours ago. Yet i still can find any solution for my problem.

    When i open the page. It only echoed post on wall. No great wall appear. You may check it out here. http://h3llst0rm.phpnet.us/upd/haha.php

    Hope you help me to sort this out. Thx

  260. Junior on Mon, 21st Jun 2010 4:40 am
  261. Hi Steven!

    thank you very much for yours articles!

    I would only know if it’s possible to add “Friend tags” or “Page tags” in stream_publish (using FBML libraries).

    ( Es.: “@[ID:4387]” -> “John” prefer pasta to pizza )


  262. piv64 on Mon, 21st Jun 2010 8:47 am
  263. Hi,
    I don’t undersantd why, but Step 4 never show me 3 screens.
    I only got “success” displayed.

    You told :
    ‘If you don’t see the below then your call back URL or Canvas URL must be incorrect, please check again your application settings and execute the URL again.’

    Can you give more explain please, my facebook application is running and everything seem good in definition of application.

    Note: I want to post messages on my wall thrue application in batch mode, not in browser context.

    Thanks for your reply

  264. Steven Robert on Mon, 21st Jun 2010 11:03 pm
  265. @piv64, you can do batch updates, the back URL or Canvas URL will be there in facebook setting page,

  266. Steven Robert on Mon, 21st Jun 2010 11:04 pm
  267. @Junior, you can add tags too

  268. piv64 on Tue, 22nd Jun 2010 5:39 am
  269. Hi,
    In fact, even if nothing else than ‘success’ is displayed, configuration for write autorization on my facebook wall is good.

    I saw a solution on application parameters in way to diagnose publish problems.
    If application is defined as ‘desktop’, everything run and many obscured problem related to stream_publish are solved.
    I think that lots of people are interested by this.

    An other problem, is there a solution to send message with accent (french text) and what’s the solution for message encoding ?

    Thank for your reply.

  270. Junior on Tue, 22nd Jun 2010 10:08 am
  271. Hi Steven,

    I thank you for the quick response!

    I’m trying with this simple code but don’t work:

    $message = ‘This message is sent by ‘;

    The problem is that facebook does not view tags and show the string as it is…

    see ‘ya

  273. Junior on Wed, 23rd Jun 2010 7:02 am
  274. Hi Steven,

    I tried but the script does not work as I want … maybe I have not explained well …

    When I post a new message on my wall I would like the tagged user display a message in its notifications like “Junior have tagged you in a post.”

    Currently, when I insert the tag as you suggested is not sent any notification to the recipient but only shows a link.

    How can I do?

  275. Steven Robert on Wed, 23rd Jun 2010 10:11 am
  276. @Junior yes its just a link tag

Thanks for the tut, i tried all the steps and it worked but i would like to use this link… https://graph.facebook.com/oauth/authorize?client_id=xxx&redirect_uri=http://apps.facebook.com/xxxx/&scope=publish_stream … in step 3.. i used the SESSIONKEY that was given to my profile and it worked… but how can i obtain the sessionkey that each user gets after granting the app permission? any way to grab theirs? i only want to post on their feeds/wall when they are online… i still don’t understand how to get each user’s sessionkey and send a post on each one of them. Thanks for any help

  288. Hi,

    I want to run a continuous fb wall posting from my cakephp code, Is there any way of doing the same, without generating this one time session key?

    If yes, earliest reply would be appreciated!


  289. Steven Robert on Sun, 18th Jul 2010 5:15 am
  290. @Joomla its mandate to generate the key

  291. Joomla Outsource India on Sun, 18th Jul 2010 11:07 am
  292. @Steven, thanks for your time and reply. Yes session key generation is must, but Is there a way; via my php script, it can generate automatic session and then post some message to users wall?

    I am running another code, for twitter, into which tweeting message, which is working perfect as needed from our project source code, but for facebook I am not able to find much useful info, so would be appreciated, if you can help somehow to get facebook wall posting working from my website script dynamically/automatically !

    Thanks in advance!

    Fatal error: Uncaught exception ‘FacebookRestClientException’ with message ‘Invalid parameter’ in /home/webdad3/public_html/AlphaProject/library/facebook-platform/php/facebookapi_php5_restlib.php:3025 Stack trace: #0 /home/webdad3/public_html/AlphaProject/webservice/ws_facebookPublishing.php(14): FacebookRestClient->call_method(‘facebook.auth.g…’, Array) #1 {main} thrown in /home/webdad3/public_html/AlphaProject/library/facebook-platform/php/facebookapi_php5_restlib.php on line 3025

  299. Jeff on Sat, 24th Jul 2010 9:41 am
  300. Ok… I followed the tutorial and it does what it says, but not what I thought it was going to do. Do you know how I can have the application post to its own wall?

    For example if a user of the site does something, I want the site to post to the application wall so all that like the application will get that as part of the news feed.

    I can’t seem to find this anywhere.

  301. Joomla Outsource India on Sat, 24th Jul 2010 11:38 pm
  302. @ Jeff

    hello Jeff, you can try to find something useful for you at below link:

    They have specially mention “A developer of the application must edit the application profile page’s Wall Settings (Edit Application > Edit) and verify under Posting Ability that Fans can write or post content on the wall is checked.”, so I am thinking its for you, which you’re finding!

  336. Hi!

    Great post!
    I would like to ask your help. I have multiple pages, created with open graph protocol, and I want to post on the page’s wall. The problem is, that the pages are created dynamic: when there is an event, I store it in a database, and I generate an open graph protocol page for the event.
    How can I post to the page’s wall? I tried putting the page’s url as target_id, but no result; I tried your code, but I’m stuck at step 3 (104 Incorrect signature method facebook.auth.getSession session_key api_key [my_app_key] v 1.0); and a few other things, but no result. :(
    Any help would be appreciated!

    Sorry to digress. But how do I allow users to register and login using their Facebook account? (the single sign-on) I cant seem to integrate Facebook with Webid for the login part. How do I authenticate users who have registered using their Facebook account to use my site & post the above news feed?

    I’m using PHP, thanks! Hope to get a reply from you soon!

  372. baljeet on Tue, 30th Nov 2010 3:10 am
  373. Hi Happismile,

    If you follow all the steps described here, there should be not problem.
    In step 3, you will get permanent session key which will be used for logging in to facebook from your site. If your site has more than one users, then you can same their session keys in local database, that session key will be used for posting, or viewing the facebook data for that user.

    Please let me know where you are facing the problem.

    I’m using localhost as my testing server. So after I completed the 5 steps above, I’m the only Facebook user able to publish on Facebook wall.

    I want to allow other Facebook users who use my site to also publish on Facebook wall. How do I get their session key using PHP for Step 2 & 3 and then save it to my database?

  386. baljeet on Wed, 15th Dec 2010 1:53 am
  387. Hi Gaurav,
    2nd and 3rd steps can be merged and can be automate dusing php. You just need to call below url (make sure yiu replace value of next quesry string to the url where you want to redirect after success.):


    If you are looking for ready-made php script for this go here
    I have created this a sample script based on the steps discussed here by Steve.

  399. FaceBook is deprecating some APIs from Jan 11, so please beware of when you create facebook apps

  400. arduinomark on Mon, 3rd Jan 2011 5:13 am
  401. it seems that some people here are stuck at step 2. I had the same problem (see post 198), and did some further research. it turns out that there is a simple alternative solution with the Graph API- got it working with a 4 step procedure as described below.

    It is still a manual solution though… I would be very interested in getting this automated. apparently one should use Graph API in future anyways, as some of the API functions used above might be deprecated soon. So a combination of the solution posted below and the php-solution to automatise this procedure as described in previous posts would be terrific… ideas anyone?

    Here’s the how I did it with the Graph API:

    1) Register a Facebook application and get App ID and App Secret 

    2) Ask the user for permission to publish posts on his wall
    (see http://developers.facebook.com/docs/authentication/#authenticating-users-in-a-web-application)


    – with client_id = your Facebook app ID, and is your and client_secret = your facebook application secret.
    – use scope argument for extended permissions (i.e. offline_access, publish_stream), you need those in order to post messages on a user’s wall (http://developers.facebook.com/docs/authentication/#requesting-extended-permissions)

    3) You will be redirected to the specified redirect_url. Copy verification string in the ‘code’ argument from the redirect URL, and paste it into this URL to get (permanent) Access Token:


    4) Browser returns Access Token. Use Access Token and Graph API functions to post messages
 to user’s wall

    …for further infos and examples see http://developers.facebook.com/docs/reference/api/post, e.g.

    curl -F ‘access_token=ACCESS_TOKEN’ \
    -F ‘message=Hello World. I like this new API.’ \
    -F ‘link=http://www.example.com/article.html’ \
    -F ‘picture=http://www.example.com/article-thumbnail.jpg’ \
    -F ‘name=Article Title’ \
    -F ‘caption=Caption for the link’ \
    -F ‘description=Longer description of the link’ \
    -F ‘actions={”name”: “View on Zombo”, “link”: “http://www.zombo.com”}’ \
    -F ‘privacy={”value”: “ALL_FRIENDS”}’ \
    -F ‘targeting= {”countries”:”US”,”regions”:”6,53″,”locales”:”6″}’ \

  427. I sent a message to the user’s wall, the operation was successful, but the message was in spam on the wall. Why?

  428. Tejas on Tue, 8th Feb 2011 3:43 pm
  429. Hi Steven, firstly thanks a lot for your tutorial. I have a question though: I followed your steps and was able to post to my facebook wall from my website. However even when someone else accesses my website it posts to my wall only. Not their wall. Am I missing something? Do we need to perform all the 5 steps with each user? Please guide me. I am very new to facebook API and I am probably doing something very foolish. Appreciate your help.

  436. Hi Steven, today I have an error on “Step2: Generate One Time Token to generate Session key”

    I changed the “API_KEY” to mine from the link:

    But it gave me an error message of:
    “An error occurred. Please try again later.” with “Okay” button underneath.
    I clicked on that “Okay” button, but it gave me the same message.

    What does it mean? And how to resolve this? Thank you.

    Well, I got it work fine yesterday, until facebook thought there’s something ‘funny’ going on and got my facebook temporary ‘suspended’ (maybe because I kept on trying to post quite frequently using php? :p).
    Then facebook asked to reset my password.
    And it went back to normal again.
    BUT, my apps GONE :(

    Couldn’t be bothered to try it again last night, so I tried your 5 steps again today.
    And everything works but not until I got to step 2.

    Help please?

    Thank you, Steven.

  437. Steven Robert on Tue, 15th Feb 2011 11:16 pm
  438. @lizzy, I seen that many FB users have similar problem, FB doesn’t work same for all users all the time, it will give some errors sometimes, keep try after some time.

  478. Hello,
    I have been trying to follow the steps in your description, but when I try to create an app I get the page “Your account must be verified before you can take this action. Please verify your account by adding your ….”
    When I put the code specified on a page (internal), the link takes me to a credit card info page. Does this code need to go on a public page? Why does it take me to a payments page? To create an app is free, right?

  479. Steven Robert on Fri, 18th Mar 2011 2:14 am

  486. thank you for such a great, detailed tutorial — excellent!

    Some of the Facebook code has changed since you posted this, and I was getting an assortment of error messages from functions that didn’t exist in the libraries I had. I finally got a clean version of matching libs at:


    Now everything works as you described… except I have one problem…

    I need to post to an “organization” page but the comments are going to the regular user page (the administrator of the organization).

    Is there any way to post to the wall of an organization/company/etc instead of posting to the wall of the user who is that org’s admin?

  491. John Wolf on Wed, 30th Mar 2011 8:52 am
  492. UPDATE – I figured it out!!

    In order to post to a wall other than your own, you need to specify the target wall in the stream_publish transaction, like this…


    …to publish to your own wall, use this shorter transaction…


    …but if you really want to go all out and put pictures and links on a target wall, follow this formula…

    $message = “This is the blurb at the very top of the post”;
    $TEMP_IMAGE = “http://yourdomain.com/images/whatever.jpg”;
    $TEMP_URL = “http://yourdomain.com/something.html”;
    $TEMP_NAME = “Bold title to right of picture”;
    $TEMP_CAPTION = “Detail paragraph below bold title “;
    $attachment = array(
    ‘name’ => $TEMP_NAME,
    ‘href’ => $TEMP_URL,
    ‘caption’ => $TEMP_CAPTION,
    ‘description’ => ”,
    ‘media’ => array(array(
    ‘type’ => ‘image’,
    ‘src’ => $TEMP_IMAGE,
    ‘href’ => $TEMP_URL))

    $action_links = array( array(‘text’ => $TEMP_NAME, ‘href’ => $TEMP_URL));

  502. Hi Steve, how are you?

    I’m doing a project and facing this obstacle for many days now.

    I have created a facebook app.
    The user can see his data after authorizing access to his account. How to i recognize who has authorized ?

    Please let me know which connect url should I use, what it will return, how will I compare the return user id with the session for logged in user so that my system will not ask same user to authenticate again and it will show data for that particular user.

  503. Eugin on Fri, 8th Apr 2011 10:24 am
  504. Hi, for two days I am trying to make this script… it\’s difficult, strnge thing… I got 1 post, but after it I got:
    Fatal error: Uncaught exception \’FacebookRestClientException\’ with message \’Incorrect signature\’ in /home/psaddonc/public_html/facebook-platform/php/facebookapi_php5_restlib.php:3025 Stack trace: #0 /home/psaddonc/public_html/facebook-platform/php/facebookapi_php5_restlib.php(916): FacebookRestClient->call_method(\’facebook.stream…\’, Array) #1 /home/psaddonc/public_html/add_news.php(29): FacebookRestClient->stream_publish(\’news http://www…\’) #2 {main} thrown in /home/psaddonc/public_html/facebook-platform/php/facebookapi_php5_restlib.php on line 3025

    don\’t understand why 1 message was posted and others no. Session key – can\’t get it, got a post without it, using this code:


    $api_key = \”*–\”;
    $secret_key = \”–\”;
    $facebook = new Facebook ($api_key, $secret_key);
    $user = $facebook->require_login();

    $message = \’news http://www.mega.cl test\';
    $has_permission = $facebook-> api_client-> users_hasAppPermission (publish_stream);

    //The user must give permission for your application publishes information on its wall.

    can you help me please?

  505. SK Imdad on Wed, 13th Apr 2011 4:19 pm
  506. Sorry my previous post did not sho up in the list. if you have received it please ignore this.
    array(‘auth_token’ => $testtoken, ‘generate_session_secret’ => true));
    $facebook_infinite_session_key = $_SESSION[‘session_key’]=$result[‘session_key’];

    $facebook = new Facebook($FB_APIKEY, $FB_SECRET);
    $infinite_key_array = $facebook->api_client->auth_getSession($auth_token);

    $facebook = new Facebook($FB_APIKEY, $FB_SECRET);
    $infinite_key_array = $facebook->api_client->auth_getSession($auth_token);

    1.This code did not printed anything. I think the session key is not generated. what’s wrong with this code?
    2. If we use the other way to generate the session key.( i.e. to follow the url to generate permanent session. ) every user have to follow that url and generate session once. The target page is not our App’s page so we can’t keep the session key in that way. If there is a way please tell me. If we have to keep user id with session then we have know the user id to get the session key. to get user id we need api call which needs session key. Isn’t it a deadlock?
    3. See, my intension is to create an app that simply when visited by user will prompt user for permission, if accepted automatically takes to a app’s page where he can publish a predefined (hard coded) message/caption, image, action links . Popups are hated.
    Please help me doing this.
    A super thanks in advance.

  507. Steven Robert on Wed, 13th Apr 2011 10:58 pm
  508. @SK Imdad Some times it gives error so try 4Step first then try to generate session key.

  510. Good morning Steve, sorry to my english.

    I can post status in the wall, but when use cron not work… Already try everything and cannot to use cron for automatize. Can be anything permission? if not use cron work!

    My code:

    api_client->session_key = FB_SESSION;

    $fetch = array(‘friends’ =>
    array(‘pattern’ => ‘.*’,
    ‘query’ => “select uid2 from friend where uid1={xxx}”));

    echo $facebook->api_client->admin_setAppProperties(array(‘preload_fql’ => json_encode($fetch)));

    $sql = $base ->query(‘SELECT * FROM wall WHERE DATE_FORMAT( data_agendada, “%H:%i” ) = DATE_FORMAT(“‘ . date(‘Y-m-d H:i:s’) . ‘”, “%H:%i”) ‘);

    while ($result = $base ->tupla($sql)) {

    echo $result [‘text_facebook’].””;

    echo “sign in”;

    if ($facebook->api_client->stream_publish($resultado[‘text_faceboon].” Testing cron”))
    echo “Added on test FB Wall”;
    } catch (Exception $e) {

    echo $e . “”;

  511. Filipi on Wed, 11th May 2011 11:50 am
  512. I’m trying to implement a code to post status on the facebook wall.
    It’s working when I directly post the message. However, I would like to use “Cron” to schedule the posts and already tried everything without success.
    Has anyone faced this problem? Can you help me with any tips?
    Is there another solution without using “Cron”?
    Thanks for your attention.

  513. Steven Robert on Wed, 11th May 2011 11:32 pm
  514. @Filipi Yes if you got permission the first time, then you can use it in cron.

  516. SOLUTION TO: “An error occurred. Please try again later.” in Step-2

    Hey everyone! – first of all, a HUGE thanks to Steven for opening Pandora’s box and letting all of us share his mad FB skilz :)

    For everyone who encountered that annoying error in Step-2, there’s a quick and easy fix.

    1) download this PHP source:


    it includes a folder called fb_kickstart
    in it you’ll find: index.php (the kick starter)
    and another sub folder called \src that contains the oAuth 2.0 version of facebook.php and the fb_ca_chain_bundle.crt file.

    2) un-pack the contents to your desktop and then edit the index.php file changing the YOUR_APP_ID and YOUR_APP_SECRET values to the ones that go with your app.

    3) push the folder over to your HTML root on the server and run:


    You’ll get a screen that asks you allow your app access to your personal FB credentials — (USE THE FIRST BUTTON AT THE TOP) — say Yes to allow access.

    Now, re-try Step-2 and it will work like a champ!

    Thanks again Steven!!!

    I was wondering if you know a better way to revoke the extended permission (“publish_stream”). I am using Javascript SDK for publishing the post on Fb.
    There is method for revoke in their legeacy api but I am not too keen on using that I was wondering if you have bettter soltn.

    A great post it would have helped a lot of ppl.

  536. Keep in mind that “stream.publish” is not fully supported aymore, it´s now in “Legacy REST API” – so if you are building a new face-app you shouldn’t use this function. Use instead Graph API. Hope this helps somebody. Happy coding!

    ‘secret’ => $app_secret,
    ‘cookie’ => true,));
    $session = $src->getSession();
    $fbme = null;
    if ($session) {

    $fbme = $src->api(‘/me?fields=id,first_name,last_name,email’);
    } catch (FacebookApiException $e) {
    if (!$fbme) {
    $login_url = $src->getLoginUrl(array(‘canvas’ => 1,
    ‘fbconnect’ => 0,
    ‘req_perms’ => ‘publish_stream’,
    ‘next’ => $app_canvas,
    ‘cancel_url’ => ‘http://apps.facebook.com/raycharles/’ ));
    echo ”;
    $user_id = $fbme[id];
    $user_first_name = $fbme[first_name];
    $token = $session[access_token];
    $message = “”;
    $link = “”;

  546. I need to send my facebook users to my wall from my welcome page.
    I have the code to determine if they are a fan. If they are not a fan, I ask
    them to become a fan by liking me. Once they do, I want to direct them
    to my wall automatically. What is the code to perform just this?
    Seems simple but I can’t seem to find any examples.

  547. Chirag on Wed, 6th Jul 2011 4:05 pm
  548. Nice tutorial..
    I have not tried the given scripts yet. Could you please tell what the following part does?
    $fetch = array(‘friends’ =>
    array(‘pattern’ => ‘.*’,
    ‘query’ => “select uid2 from friend where uid1={$user}”));
    echo $facebook->api_client->admin_setAppProperties(array(‘preload_fql’ => json_encode($fetch)));

  552. To send users to another website or to an app on your facebook page, you can use the PHP code as described here:
    Now on your facebook welcome page, once you determine they are a fan, use this code to send them to your app. However, I do not know the code how to send a user to the wall, just an app. That would be useful to know as well.

  566. @arron, Its better if you host on a public domain , not localhost.

  568. HI Steven ,
    I have created a new application on FB.I can access it from new Tab ,but my friends or anyone on FB cannot access it…They cannot get it.I have to publish or submit my newly created Apps?

  569. Steven Wall on Wed, 21st Sep 2011 11:01 pm
  570. @sanjay Your friends should be able to see it , did u changed any settings on ur FB? To publish on their walls they need to give permission.

  576. Hi Steven,

    Thanks for such a great post. We are also doing the same task for one of our website. We are able to fetch the User details as well as User’s Friend List. User’s friend list means the details of friends and relatives, whom user has added in his Facebook account.

    But we are facing problems In:
    1. Getting the email Id and Mobile number of User’s Friend.
    2. Posting a dynamic message on the wall of multiple friend’s (User’s Friend). We do not have the email id of the friends but we have a unique Facebook id of all these friends of the user. We want to post a message on friend’s wall using the same id.

    The functionality is like given below:

    User will login to our website and will select multiple friends/relatives from his friend list that we had fetched from Facebook. Then he will write a message for all his selected friends.
    When he will click on submit button, we want to post a message like, has sent a message to to invite him to meet at . Please click the link to view more details about the user.

    This message should post on the wall of all the selected friends. We have and stored in database.

  580. Hi Stevan,

    I tried your code and it worked for me but i have few problem regarding posting. Actually, Whenever I try to logged in with different users, the wallpost goes with same name off APPS admin. [Nischal Tiwari] like that.

    I have a login/logout feature that means who ever sign in, i want to see their name in the wallpost instead of Apps admin. Is that possible ?

    Let me know

  581. Jose on Tue, 28th Feb 2012 6:00 am
  582. Hi Steven,

    I done these 5 steps and it is working perfectly into the profile wall. But i want it post to page wall. i have seen that you mentioned regarding target id. I am not able to find where i can do that. I am looking forward to your reply.

  584. Hi,

    I am creating a ASP.NET application and i want to do same thing for ASP.NET, here the Example is explained in PHP. SO can you help me how to implement in ASP.NET(In Both C#,VB).

    Sanjay Soral

  585. Jim on Fri, 9th Mar 2012 5:15 pm
  586. First, thank you so much. I’ve been searching and banging my head against the wall for days trying to get this kind of thing to work.

    I did exactly what you said and it worked like a charm.

    Now to implement it on my site. I’m going to post the idea here in case you can help figure it out before I get to it later.

    I’m using the facebook registration plugin for registration, then saving their fb id in a database. Then I have a database of quotes and I want to be able to have them click “share” and have it post to their wall. They have to be logged on to fb and registered with the site in order to even see the quotes.

    What I have to figure out is what to do with the Step 2 and 3 stuff there. Does each user have to physically copy the code from step 2, or can I access it another way? Do I need to get the session key for each user in Step 3 only once, then save it in my database to use when that particular user shares?

    Off to play. I’m just thrilled you’ve given me a starting point. When I know it “CAN” work, I’m much better at finding out how to make it work.

  587. Kevin on Tue, 8th May 2012 3:32 am
  588. Hi Steven,
    I did the all steps. But I don’t know how to run the php code or what should I use to run the php code. Could you teach me? Thank you so much.

  604. Hi,

    I have obtained the one time session as suggested above add set the Permission for wall as suggested but when I see the step5 Publishing the message on Facebook Wall, and followed it I got some errors.

    When I see the PHP SDK there is no code for the function $facebook->api_client->admin_setAppProperties and event there is no code for $facebook->api_client->session_key = FB_SESSION;

    Please suggest how it can be done with the latest PHP SDK code.
