Publish on Facebook Fan Page as fan user Using PHP

First Follow all the steps to give permissions to publish on Facebook. http://blog.theunical.com/facebook-integration/5-steps-to-publish-on-a-facebook-wall-using-php/

Add FaceBook application to your fan page

Just Go to http://www.facebook.com/apps/application.php?id=ID_OF_YOUR_APP.

Find link ‘Add to my Page’ on the left, click on it. Find your page on the list and click on ‘Add to page’ next to this page.

Set Your Application type as WEB

Go to http://www.facebook.com/developers/editapp.php?app_id=ID_OF_YOUR_APP.

Choose ‘Web’ next to ‘Application type’ and click on ‘Save Changes’ button.

Add permissions to your app

Prepare special link:

http://www.facebook.com/connect/prompt_permissions.php?api_key=YOUR_API_KEY&v=1.0&next=http://www.facebook.com/connect/login_success.html?xxRESULTTOKENxx&display=page&ext_perm=publish_stream,offline_access&enable_profile_selector=1&profile_selector_ids=ID_OF_YOUR_PAGE

replace YOUR_API_KEY for an API KEY of your application and ID_OF_YOUR_PAGE for an id of your page

Run this URL in your web browser. Click on ‘Allow’. This will set the permissions to your application to publish on page.

You should see a message: ‘Success’ message.

Check Permissions

Go to http://developers.facebook.com/tools.php?app_id=ID_OF_YOUR_PAGE and check your permissions.

Choose your application, change ‘Response Format’ to JSON, choose method ‘users.hasAppPermission’, fill publish_stream in ext_perm and id of your page in uid.

You should see result: 1.

That means that everything is ok. If the result is 0. then something went wrong.  Then check all the above steps again.

Code To Publish on Fan Page as Fan User Using PHP

Then to publish on fan page as a Fan page user and not the facebook user just follow below code.

For this you need to get Fan page ID:

Example : http://www.facebook.com/pages/Fan-Page/xxxxxxx

where xxxxxxx is the fan page id.

In Steam publish method just replace the $page_id with your above fan page id.

stream_publish($message, $attachment,$action_links, null,$page_id).

<?php

// FB_APIKEY is your facebook application api key
// FB_SECRET is your application secrete key

define('FB_APIKEY', 'YOUR_APIKEY');
define('FB_SECRET', 'YOUR_SECRET');
define('FB_SESSION', 'YOUR_SESSION_key');

require_once('facebook-platform/php/facebook.php');

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 Fan Page as Fan User';
$page_id ="xxxxxxxxxxx";
if( $facebook->api_client->stream_publish($message, $attachment,$action_links, null,$page_id))
 echo "Added on FB Wall on Fan Page";
} catch(Exception $e) {
 echo $e . "<br />";

}
?>

Below is the screen where you can see the message published are fan user.

Simple 5 Steps to publish on a facebook wall using DotNet C#/ cSharp

There are many Libraries available for C# and Dotnet to publish on facebook.

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

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.

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

Fill in application Name

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.

Now goto Canvas link and enter any url.

Next goto Connect URL link and enter the same url.

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 any of the available libraries on facebook http://wiki.developers.facebook.com/index.php/User:ASP.NET

(OR)

Microsoft SDK for Facebook Platform, which supports Facebook Connect, FBML and IFrame canvas page applications, and ASP.NET MVC. For issues and discussions about the SDK see the project on Codeplex.

Step2: Generate One Time Session key

How to generate One Time Session key:

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

https://login.facebook.com/code_gen.php?api_key=API_KEY&v=1.0

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

Then we will get a temporary token key.

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

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

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

Step4:

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 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 with Image and link on Facebook Wall using cSharp/ C#

Publishing a Post With Image and Action Link in C# using facebook developer toolkit v2

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

public void Post(facebook.API fbAPI, string appLink)
{
 string response = fbAPI.stream.publish( "publish steven on facebook.",
new attachment() {
name = "I am a good guy !", href = appLink, caption = "{*actor*} Steven Publish on facebook wall",
description = "Helping other people, I became a new good guy.", properties = null,
 media = new List<attachment_media>() { new attachment_media_image()
{ src = "http://blog.theunical.com/wp-content/uploads/2009/11/start-application.jpg", href = appLink } } },
new List<action_link>() { new action_link() { text = "Become a good guy",
 href = appLink } }, null, 0);
}

According to facebook Wiki posting on a  wall is very confusing and very difficult to write a program to publish on a wall. And it Don’t even support or document any methods on how to publish on wall using JAVA, and thanks to Google for giving a JAVA library to post on facebook.

Download Library from http://code.google.com/p/facebook–java–api/

Don’t confuse and don’t use old libraries only use facebook-java-api-3.0.1-bin.zip or greater.

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 simple steps to publish on a Facebook wall using JAVA.

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.tar1.gz”. For now we will use this library for generating one time session key.

Step2: Generate One Time Token key

How to generate One Time Token key:

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

https://login.facebook.com/code_gen.php?api_key=API_KEY&v=1.0

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

Then we will get a temporary token key.

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

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

/**
 * FacebookClient
 *
 */
public class FacebookClient {
 public static String API_KEY = “YOUR API KEY”;
 public static String SECRET = “YOUR SECRET”;
 public static void main(String args[]) {
 // Create the client instance
 FacebookRestClient client =       new FacebookRestClient(API_KEY, SECRET);
 client.setIsDesktop(true); // is this a desktop app

 try {
 String token = client.auth_createToken();
 // Build the authentication URL for the user to fill out
 String url = “http://www.facebook.com/login.php?api_key=”
 + API_KEY + “&v=1.0″
 + “&auth_token=” + token;
 // Open an external browser to login to your application
 Runtime.getRuntime().exec(“open ” + url); // OS X only!
 // Wait until the login process is completed
 System.out.println(“Use browser to login then press return”);
 System.in.read();

 // fetch session key
 String session = client.auth_getSession(token,true );
// obtain temp secret
String tempSecret = client.getSessionSecret();
// new facebook client object
client = new FacebookJaxbRestClient(API_KEY, tempSecret, sessionKey);

 System.out.println(“Session key is ” + session);

 // keep track of the logged in user id
 Long userId = client.users_getLoggedInUser();
 System.out.println(“Fetching friends for user ” + userId);

 // Get friends list
 client.friends_get();
 FriendsGetResponse response = (FriendsGetResponse) client.getResponsePOJO();
 List<Long> friends = response.getUid();

 // Go fetch the information for the user list of user ids
client.users_getInfo(friends, EnumSet.of(ProfileField.NAME));

UsersGetInfoResponse userResponse = (UsersGetInfoResponse) client.getRepsonsePOJO();
 // Print out the user information
 List<User> users = userResponse.getUser();
 for (User user : users) {
 System.out.println(user.getName());
 }
 } catch (FacebookException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 } catch (IOException e) {
 // TODO Auto-generated catch block
 e.printStackTrace();
 }
 }

5 Steps to publish on a facebook wall using 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.

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

Fill in application Name

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.

Now Click on Website Link to get API Key

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.

https://login.facebook.com/code_gen.php?api_key=API_KEY&v=1.0

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

Then we will get a temporary token key.

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.

<?php

// FB_APIKEY is your facebook application api key

// FB_SECRET is your application secrete key

$FB_APIKEY="YOUR_API";

$FB_SECRET="YOUR_SECRET";

$fb = new FacebookRestClient($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>";

print_r($result);

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

?>

(OR)

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.

http://www.facebook.com/login.php?api_key=APIKEYXxxxxxxxxxxxxxxxxx&connect_display=popup&v=1.0&next=http://www.facebook.com/connect/login_success.html&cancel_url=http://www.facebook.com/connect/login_failure.html&fbconnect=true&return_session=true&req_perms=read_stream,publish_stream,offline_access

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.

<?php

define('FB_APIKEY', 'YOUR_APIKEY');

define('FB_SECRET', 'YOUR_SECRET');

define('FB_SESSION', 'YOUR_SESSION_key');

require_once('facebook-platform/php/facebook.php');

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 />";

}

?>
