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:

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.

Do you aware of this error?
How to fix this.
Any input is appreciated.

Steven Robert on Wed, 11th Nov 2009 11:06 pm


After step4 did you see the privilege screen from facebook.
we need to give permissions to publish on facebook. Let me know if you have any questions.

Steven Robert on Wed, 2nd Dec 2009 1:13 pm

chad james on Sat, 26th Dec 2009 6:06 am


Hey I created a facebook application for my blog called QIT Interact, The problem I’m running into is I’m new to all this etc and I’m trying to work out if there is way that I can have my application published to feeds say when a new post has been posted etc rather then looking up the application etc. Ideally what I’m wanting to do is rig it so it will always send a message to streams any help would be greatly appreciated

Steven Robert on Sat, 26th Dec 2009 10:53 pm


Yes, We can. what kind of application you are building

Hi Steven, Actually i want to post my data from my pc on the facebook wall.. like image, title and description by above script…Is it possible? how?

Steven Robert on Fri, 1st Jan 2010 9:45 pm


Yes but the image should be in a public path like it should be accessible from any where.

vishal on Mon, 4th Jan 2010 5:15 am


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.
require_frame();
$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);
$facebook->api_client->stream_publish($description,$attachment,$action_links);
?>

Please help.

Thanks in advance.

Steven Robert on Mon, 4th Jan 2010 9:47 pm


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.

Vishal on Mon, 11th Jan 2010 6:41 am


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?

Steven Robert on Mon, 11th Jan 2010 10:53 pm


Hi Vishal,
Why you want to type this URL “http://apps.facebook.com/theunicalblogtest/”. you can just execute your program.

Tomee on Fri, 15th Jan 2010 3:37 am


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.

Steven Robert on Fri, 15th Jan 2010 10:56 pm


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.

Steven Robert on Fri, 15th Jan 2010 10:58 pm


Tomee, If you get errors then try again from step2.

Tomee on Sat, 16th Jan 2010 9:00 am


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.

Steven Robert on Mon, 18th Jan 2010 12:44 am


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.

shyam on Tue, 19th Jan 2010 9:20 am


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,
SHyam

Steven Robert on Wed, 20th Jan 2010 4:32 am


Shyam did you tried downloading the code from here? http://blog.theunical.com/?attachment_id=267142

Steven Robert on Wed, 20th Jan 2010 4:33 am


Shyam did you tried downloading the code from here?
http://blog.theunical.com/?attachment_id=267142

Maria on Thu, 21st Jan 2010 7:37 pm


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.

Maria on Thu, 21st Jan 2010 7:40 pm


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.

Maria on Thu, 21st Jan 2010 7:54 pm


And finally, this link does not show any code

http://blog.theunical.com/?attachment_id=267142

Steven Robert on Thu, 21st Jan 2010 10:50 pm


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

Steven Robert on Thu, 21st Jan 2010 10:51 pm


Maria, This should be replaced by facebook secret key and facebook app key

Steven Robert on Thu, 21st Jan 2010 10:53 pm


Yes Maria, the code should be executed on server.

Tomee on Fri, 22nd Jan 2010 11:16 am


Thank you steven I managed to publish on my wall finally can you help in making publish possible from my app ?

Steven Robert on Fri, 22nd Jan 2010 10:52 pm


Hi Tomee, You can just create a Iframe of your existing application and try it in Facebook App.

Tomee on Sat, 23rd Jan 2010 6:49 am


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

Steven Robert on Sat, 23rd Jan 2010 10:56 pm


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.

Fabio on Mon, 25th Jan 2010 11:08 pm


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

Fabio

Steven Robert on Mon, 25th Jan 2010 11:10 pm


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

Fabio on Tue, 26th Jan 2010 7:32 am


Good…i have permission…i’m administrator of the Fan Page.
Can you give me some php code suggestion?

Steven Robert on Tue, 26th Jan 2010 10:11 am


Hi Fabio,
Here is the example PHP code and the screenshots in my next post to publish on a Facebook fan’s page.
http://blog.theunical.com/facebook-integration/simple-steps-to-publish-on-facebook-fan-page-using-php/
If you still have any difficulties we can develop any facebook applications for you.

shyam on Thu, 28th Jan 2010 5:52 am


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 .

Regards,
SHyam

Steven Robert on Thu, 28th Jan 2010 9:59 pm

faemino on Fri, 29th Jan 2010 8:31 am


Just thanks for all your articles about Facebok conection from PHP. Great resource and nice job.

Maria on Fri, 29th Jan 2010 3:24 pm


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?

Steven Robert on Fri, 29th Jan 2010 9:58 pm


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.

Rangga on Sat, 30th Jan 2010 7:24 am


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..

Jim on Sat, 30th Jan 2010 3:48 pm


Thank you! After many days of search, google’ing and testing this page was the key to posting messages to an offline user

Steven Robert on Sat, 30th Jan 2010 11:16 pm


Rangga, this code work’s perfect on mobile web too.

fede on Mon, 1st Feb 2010 2:58 pm


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.
Success.!!!!!!!!!!!!!!11

Sebastien on Wed, 3rd Feb 2010 10:09 am


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!

Steven Robert on Wed, 3rd Feb 2010 9:57 pm


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.

Aziz on Thu, 4th Feb 2010 9:33 am


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.

Kapil Jadhav on Fri, 5th Feb 2010 9:10 am


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,
Kapil

Aziz on Mon, 8th Feb 2010 6:07 am


Ohh i am so stupid ))) Thx it worked. this method is great!!

Your coding is used to message display on user wall

have u help me …??

thanks in advance

TheTester on Fri, 19th Feb 2010 7:16 am


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?

Steven Robert on Fri, 26th Feb 2010 12:22 am


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.

Sylvester Faro on Thu, 4th Mar 2010 6:48 am


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…

Steven Robert on Thu, 4th Mar 2010 9:52 pm


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.

abrahan on Mon, 8th Mar 2010 8:33 pm


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?

Steven Robert on Mon, 8th Mar 2010 10:45 pm


Hi Abrahan, This Canvas URL and connect URL should be a publicly accessible URL.

navjot singh on Tue, 16th Mar 2010 6:42 am


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.
each time after the permission if try to publish i get the below error.
‘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

regards
navjot

Steven Robert on Tue, 16th Mar 2010 9:01 am


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.

Dinesh on Tue, 16th Mar 2010 9:36 am


Hi Steven,
Pls help me

Steven Robert on Tue, 16th Mar 2010 10:04 am


Dinesh The URL need to be Public Available URL and not a local URL, Check it once. Are you trying with a public URL?

Sylvester Faro on Thu, 18th Mar 2010 7:13 am


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.

What do I need to change on these steps to post to that page’s wall?

Bruno Gomes on Thu, 18th Mar 2010 10:47 pm


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
http://www.facebook.com/bmag2009

My Application name is
Creative-mood
http://www.facebook.com/apps/application.php?id=356981166204&ref=nf

My Fan page is:
bmag-01
http://www.facebook.com/pages/bmag-01/335140057869

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

Chandan on Fri, 19th Mar 2010 12:06 am


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?

Chandan Singh on Fri, 19th Mar 2010 2:20 am


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.

Steven Robert on Fri, 19th Mar 2010 4:26 am


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

Steven Robert on Fri, 19th Mar 2010 4:29 am


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.

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

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 ?

Steven Robert on Fri, 19th Mar 2010 10:59 pm

Ok Bruno I will write up a post for you.

Nick on Wed, 24th Mar 2010 3:16 am


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…

Luca on Wed, 24th Mar 2010 10:16 am


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

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/

Saurabh on Sun, 28th Mar 2010 1:52 pm


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 ?

Steven Robert on Sun, 28th Mar 2010 10:46 pm


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.

kirochi on Mon, 29th Mar 2010 12:10 pm


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)

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);

Steve – great tutorial and I thank you for the time and detail you put into it. I am having trouble with step #3 generating the session key. I downloaded your script generatesession.key.php put in my api key and secret but get the following error when executing:

Fatal error: Uncaught exception ‘FacebookRestClientException’ with message ‘Invalid parameter’ in /web/sites/widgets/facebook/facebook-platform/facebook-platform/php/facebookapi_php5_restlib.php:3025

Any advice is greatly appreciated.

Rio MobineSSia on Fri, 23rd Apr 2010 11:57 pm


I’m developing mobile web application (xHTML) in PHP which already success connected to fb.
But I still confuse for asked permission (Step 4 on your guide above) in mobile way.
Do you know how to adopt your Step #4 above to be run on mobile micro browser?
Thx in advance.

Steven Robert on Sun, 25th Apr 2010 8:02 am


Rio You can execute Step4 in mobile version too

Steven Robert on Sun, 25th Apr 2010 8:22 am


Darrasin try the other link I updated in post for Step3.

BKC on Sun, 25th Apr 2010 1:20 pm


Love the blog. Step 4 failed with error fbconnect must be boolean. Replacing true with 1 seems to work.

newbie on Sun, 25th Apr 2010 1:22 pm


steve, u skipped my question
help please. thanx

Steven Robert on Sun, 25th Apr 2010 9:34 pm


Yes BKC it seems facebook changed its api for true/false to 1/0.

Steven Robert on Sun, 25th Apr 2010 9:36 pm


Yes Uber,
replace true with number 1 and try.

hi steven

very nice post thanks man. I am facing one issue.

I want is abuot creating avatar and people can come and like or dislike any avatar. even this avatar is created by a friend or not.

now i want my app to publish on person A wall, if person B comes and like his/her avatar in the app & both are not even friends.
Both person A and B have given exntended permission to the app also and are not friend.

I am using following publish stream code

$facebook->api_client->stream_publish($message,null,null,$personA_id,$app_id)

Its showing this error

post on wallexception ‘FacebookRestClientException’ with message ‘The user hasn’t authorized the application to perform this action’ in /home/jill/web/php/facebook-platform/php/facebookapi_php5_restlib.php:3374 Stack trace: #0 /home/jill/web/php/facebook-platform/php/facebookapi_php5_restlib.php(932): FacebookRestClient->call_method(’facebook.stream…’, Array) #1 /home/jill/web/public/samsung/style-n-win-dev/insert-services2.php(54): FacebookRestClient->stream_publish(’From My App: pu…’, NULL, NULL, ‘100000845001406′, ‘109444382410730′) #2 {main}

but if I use following code which person B comes and likes his own avatar it works and publish post on the wall without error.
$facebook->api_client->stream_publish($message,null,null,$personB_id,$app_id)

please can you guide me where i am doing mistake.

thanks a lot

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

I run the test code and got the following error:

Any idea?

Aziz on Tue, 11th May 2010 5:48 am


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.

Steven Robert on Tue, 11th May 2010 8:19 am


Aziz,
Which function are u referring, Face book has changed some of the api settings.

Aziz on Tue, 11th May 2010 9:07 am


I am using
$facebook->api_client->stream_publish();
$facebook->api_client->photos_upload();
$facebook->api_client->video_upload();

Steven Robert on Tue, 11th May 2010 11:35 pm


Aziz, Try download the library from above, facebook has changed its library. The methods you are using still work.

Aziz on Wed, 12th May 2010 5:05 am


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

nikhil on Thu, 13th May 2010 8:10 am


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
thanx

Steven Robert on Thu, 13th May 2010 8:35 am


Hi Nikhil, If the user gives permission to their wall then you can publish on their wall too.

nikhil on Thu, 13th May 2010 8:45 am


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

Steven Robert on Thu, 13th May 2010 10:42 am


No Nikhil, Your API will be sufficient, They just need to give permission to their wall.

Hi steven,

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

Junior on Mon, 21st Jun 2010 4:40 am


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 )

bye

piv64 on Mon, 21st Jun 2010 8:47 am


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

Steven Robert on Mon, 21st Jun 2010 11:03 pm


@piv64, you can do batch updates, the back URL or Canvas URL will be there in facebook setting page,

Steven Robert on Mon, 21st Jun 2010 11:04 pm


@Junior, you can add tags too

piv64 on Tue, 22nd Jun 2010 5:39 am


Hi,
In fact, even if nothing else than ’success’ is displayed, configuration for write autorization on my facebook wall is good.

Important:
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.

Junior on Tue, 22nd Jun 2010 10:08 am


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

Steven Robert on Wed, 23rd Jun 2010 12:13 am


@Junior here is how you add tags to your post http://blog.theunical.com/facebook-integration/facebook-api-how-to-add-tags-to-post-api-using-php/

Junior on Wed, 23rd Jun 2010 7:02 am


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?

Steven Robert on Wed, 23rd Jun 2010 10:11 am


@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

Junior on Sun, 27th Jun 2010 12:44 pm


Hi Steven,

it’s possible to publish a message on the wall of the friends of the app/funpage?

Ex.:

1. User visit my site

2. The user publish a message on my site

3. My site publish this message on the facebook wall of the User

how do I write permissions?

Ernestas on Mon, 28th Jun 2010 6:34 pm


Same question as Junior.

dinesh on Wed, 7th Jul 2010 3:27 pm


is there any script by which i can use user’s facebook login details, and can post something on user’s wall, as this can be done for twitter using cURL lib of php

thanks in advice ….

Joomla Outsource India on Sat, 17th Jul 2010 6:39 am


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!

JOI

Steven Robert on Sun, 18th Jul 2010 5:15 am


@Joomla its mandate to generate the key

Joomla Outsource India on Sun, 18th Jul 2010 11:07 am


@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!

Jeff on Thu, 22nd Jul 2010 5:40 pm


I’m getting the following error when trying to run the code. I actually tried combining the snippets into 1 page and this is what I got. Any ideas?

Ignore my comment. I got it to work. The tutorial does what it says it does

Steven Robert on Thu, 22nd Jul 2010 11:44 pm


@ Jeff you can’t combine all the steps in one page, you need to do it seperatly

Jeff on Sat, 24th Jul 2010 9:41 am


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.

Joomla Outsource India on Sat, 24th Jul 2010 11:38 pm


@ Jeff

hello Jeff, you can try to find something useful for you at below link:
http://wiki.developers.facebook.com/index.php/Stream.publish

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!

Cheers!

Tell me what you're thinking...
