I am already using oAuth and the Gr

Answer 1

To clarify, 'post' here refers to the HTTP method, as in GET/POST. See https://github.com/facebook/php-sdk/blob/master/src/base_facebook.php : protected function _graph($path, $method = 'GET', $params = array())

$result = $facebook->api( '/me/feed/', 'post', array('access_token' => $this->access_token, 'message' => 'Playing around with FB Graph..') );

Answer 2

You'll need the "publish_stream" extended permission in order to write to the feed. Here is a complete list of them: http://developers.facebook.com/docs/authentication/permissions.

In order to get the extended permission, get the authorization token in this way:

https://graph.facebook.com/oauth/authorize?
client_id=...&
redirect_uri=http://www.example.com/callback&
scope=publish_stream

Okay, I finally solved this. Thanx to phpfour for your help :-)

First: My connection-url looks like this (with "publish_stream"):

$connectUrl = $this->getUrl(
  'www',
  'login.php',
  array_merge(array(
    'api_key'         => $this->getAppId(),
    'cancel_url'      => $this->getCurrentUrl(),
    'req_perms'       => 'publish_stream',
    'display'         => 'page',
    'fbconnect'       => 1,
    'next'            => $this->getCurrentUrl(),
    'return_session'  => 1,
    'session_version' => 3,
    'v'               => '1.0',
  ), $params)
);

Second; I tried to post to facebook via

$result = $facebook->api(
    '/me/feed/',
    array('access_token' => $this->access_token, 'message' => 'Playing around with FB Graph..')
);

But the correct way to do this is include one more parameter ('post'):

$result = $facebook->api(
    '/me/feed/',
    'post',
    array('access_token' => $this->access_token, 'message' => 'Playing around with FB Graph..')
);

In addition to chf,

After posting:

$getLinkToken='https://graph.facebook.com/oauth/access_token'.
              '?client_id=YOUR_APPID'.
              '&redirect_uri=YOUR_SITE'.
              '&client_secret=YOUR_SECRET'.
              '&code=CODE_KEY';

I got the response:

 https://graph.facebook.com/oauth/access_token?
    client_id=xxxxxxxxxxxxxx
    &redirect_uri=myurl
    &client_secret=xxxxxxxxxxxxxx
    &code=xxxxxxxxxxxxxx

no which one is access_token, client_secret or code

$facebook->api( '/YOUR_APPID/feed/', 'post', 
array('access_token' => $this->access_token,
'message' => 'Playing around with FB Graph..'));

Answer 5

Instead of using the below code

[facebook dialog:@"feed"
 andParams:params 
 andDelegate:self]; 

Use the following solution

[facebook requestWithGraphPath:@"me/feed" andParams:params andHttpMethod:@"POST" andDelegate:self];

Answer 6

That is old way to get acces. In GRAPH first i generated code key with:

$getLinkCode ='https://graph.facebook.com/oauth/authorize'.
              '?client_id=YOUR_APPID'.
              '&redirect_uri=YOUR_SITE'.
              '&scope=publish_stream';

And now when we have code key we can generate access_token from link:

$getLinkToken='https://graph.facebook.com/oauth/access_token'.
              '?client_id=YOUR_APPID'.
              '&redirect_uri=YOUR_SITE'.
              '&client_secret=YOUR_SECRET'.
              '&code=CODE_KEY';

But this access_token post your message as USER not APPLICATION... WHY?!

If you want post on application wall use:

$facebook->api( '/YOUR_APPID/feed/', 'post', array('access_token' => $this->access_token, 'message' => 'Playing around with FB Graph..'));
