Publishing to User's Wall Without Being Online/Logged-In - Facebook Sharing Using Graph API

Publishing To User's Wall Without Being Online/Logged-in - Facebook Sharing Using Graph API

I suggest you start learning how Facebook Graph API works first.

1. Facebook will NEVER share the user password with you!
2. If you just need to give the user the possibility to share link, then just use the like plugin. You may also find more interesting social plugins to use in your website.
3. If you use the like plugin, it won't open any popups and it would post the link directly to the user's wall.
4. You could always use the Feed Dialog
5. Start reading the Facebook Documentation

---

Now to post on the user's wall (on his behalf) without him being logged-in, you need the following:

1. app access_token
2. publish_stream permission, NO NEED for the long-lived access token:

Enables your app to post content, comments, and likes to a user's
stream and to the streams of the user's friends. This is a superset
publishing permission which also includes publish_actions. However,
please note that Facebook recommends a user-initiated sharing model.
Please read the Platform Policies to ensure you understand how to
properly use this permission. Note, you do not need to request the
publish_stream permission in order to use the Feed Dialog, the
Requests Dialog or the Send Dialog.

Require the permission:
This can be done in multiple of ways:

Using the Login Plugin:

<div class="fb-login-button" data-show-faces="true" data-width="200" data-scope="publish_stream" data-max-rows="1"></div>

Server-side login (Redirect to the OAuth Dialog):

https://www.facebook.com/dialog/oauth?
     client_id=YOUR_APP_ID
     &redirect_uri=YOUR_URL
     &scope=publish_stream
     &state=SOME_ARBITRARY_BUT_UNIQUE_STRING

PHP-SDK:

$loginUrl = $facebook->getLoginUrl(array("scope"=>"publish_stream"));

JS-SDK through the FB.login method:

 FB.login(function(response) {
   if (response.authResponse) {
     console.log('Welcome!  Fetching your information.... ');
     FB.api('/me', function(response) {
       console.log('Good to see you, ' + response.name + '.');
       FB.logout(function(response) {
         console.log('Logged out.');
       });
     });
   } else {
     console.log('User cancelled login or did not fully authorize.');
   }
 }, {scope: 'publish_stream'});

Publishing:

$USER_ID = "XXXXXXXX"; // Connected once to your APP and not necessary logged-in at the moment
$args = array(
    'message'   => 'Hello from app',
    'link'      => 'http://www.masteringapi.com/',
    'caption'   => 'Visit MasteringAPI.com For Facebook API Tutorials!'
);
$post_id = $facebook->api("/$USER_ID/feed", "post", $args);

Note:
While it's possible to post without the user's presence always remember Facebook recommends a user-initiated sharing model

Publish Stream from the application - for non logged in user, using Graph API, php SDK

this is just a recommend & i'm not sure this be the answer
Destroy all of the sessions (or use your browser in private mode -for Firefox )
& then visit sender page Like this

example.com/postfarm.php

maybe when you visit the page normally the app gets your access_token & tries to post as you

PS:better way

use this code & you dont need to destroy sessions anymore

    include_once ('src/facebook.php');/// include sdk
    ////// config The sdk
        @ $facebook = new Facebook(array(
        'appId'  => 'XXXXXXX',
        'secret' => 'XXXXXXXXXXXXXX',
         ));
$facebook->destroySession();
    try{        
    $post=$facebook->api('USER_ID/feed/','POST',array(
    'message' => '$message',
    'link'=>'http://apps.facebook.com/xxxxxxx/link.php?link=',
    'picture'=> 'XXXXXXXXXX',
    'name'=>'XXXXXX',
    'description'=>'yes',

    ));
    }
    catch(FacebookApiException $e) {
    echo $e->getType();
    echo '<br />';
    echo $e->getMessage();
     }

Publishing to User's Facebook Wall with Facebook PHP SDK

PHP-SDK 3.1.1

To generate app and user tokens. $app_access_token & $access_token

*The user access_token if you have offline access will never expire, unless user deAuthorizes your app. You would need to use for posting to a users wall when they are offline or not interacting with your application.*

<?php
require './src/facebook.php';
$facebook = new Facebook(array(
  'appId'  => '135669679827333',
  'secret' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
));
 $user = $facebook->getUser();
 if ($user) {
   try {
     // Proceed knowing you have a logged in user who's authenticated.
     $user_profile = $facebook->api('/me');
   } catch (FacebookApiException $e) {
     error_log($e);
     $user = null;
   }
 }
 if ($user) {
   $logoutUrl = $facebook->getLogoutUrl();
 } else {
   $loginUrl = $facebook->getLoginUrl();
 }
// Create Application Access Token
$app_access = "https://graph.facebook.com/oauth/access_token?client_id=135669679827333&client_secret=xxxxxxxxxxxxxxxxxxxxxxxx&grant_type=client_credentials";
$app_access_token = file_get_contents($app_access);
// If we have a user who is logged in, create access_token with session.
if ($user) {
$access_token = $_SESSION['fb_135669679827333_access_token'];
}
?>

How to Post facebook wall automatically with Facebook API (only with userid)

below code helps you to get permissions from user and access the user's information:

$dialog_url = "http://www.facebook.com/dialog/oauth?client_id=". $app_id . "&redirect_uri=" . urlencode($my_url) . "&scope=publish_stream,user_about_me,read_friendlists,offline_access,publish_actions,friends_photos,,user_photos". "&state=" . $_SESSION['state'];

echo("<script> window.location.href='" . $dialog_url . "'</script>");

Post to a Facebook user's wall from a page or app

It's not possible to post on the user's wall as app or page. And even if it's possible, it's not recommended!

Your best bet if you want to notify your fans about something is to post on your page's wall (as your page) where this post will appear in your fans news feed.

Also this can be done for your website fans (Likers): https://developers.facebook.com/blog/post/465/
