Question

Using graph api publish_stream permission: together with offline_access permission:

As described here and here. However for some reason one of the following two things are happening:

I am trying to post to a facebook user which is not currently logged in, following an action of a user which is curently logged in (e.g. telling user #1 that user #2 visited their farm in farmville, but user #1 is not logged in, while user #2 is. And they are not necessarily friends).

When I tried this using the following code, the post was not created when users #1 and #2 were not friends (first problem), and when they were friends, the post was being created, but seemed like user #2 was posting it on user #1’s wall (second problem – this is NOT what I am trying to do, I want it to be anonymous).
See the first code I used:

    $post_id = $facebook->api('/' . $user1_id . '/feed/', 'post', array(
    'message' => 'Someone just visited your farm',
    'link' => 'http://example.com',
    'picture'  => 'http://example.com/img/picture.jpg',
    'caption' => 'Visit farms!'
    ));

So I tried to use the access token of user #1, which he gave me when he was logged in, and the application is supposed to be able to post on their wall even when they are offline (even without offline_access permission – see here facebook’s documentation: “you can publish… without requiring offline_access”. At any rate, when I am adding the access_token to the array as a parameter (see the code below), no post is being created at all:

    $post_id = $facebook->api('/' . $user1_id . '/feed/', 'post', array(
            'access_token' => $user1_access_token,
    'message' => 'Someone just visited your farm',
    'link' => 'http://example.com',
    'picture'  => 'http://example.com/img/picture.jpg',
    'caption' => 'Visit farms!'
    ));

What should I do?

gain, I am simply trying to publish to user’s wall that is NOT logged in, but who gave me the publish_stream permission, a post from the application, not any other user, telling this user that someone (anonymously) has “visited their farm” (or created some action associated with them).

Thanks everyone.

Answer 1

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();
     }
