Facebook Graph Api - Posting to Fan Page as an Admin

I've setup a script which allows users to post messages to a fan page on Facebook. It all works but there's one small issue.

The Problem:

When the post is added to the page feed it displays the posting user's personal account. I would prefer it to show the account of the page (like when you're admin of the page it says it came from that page). The account I'm posting with have admin rights to the page, but it still shows as a personal post.

HTTP POST

$url = "https://graph.facebook.com/PAGE_ID/feed";
$fields = array (
    'message' => urlencode('Hello World'),
    'access_token' => urlencode($access_token)
);

$fields_string = "";
foreach ($fields as $key => $value):
    $fields_string .= $key . '=' . $value . '&';
endforeach;
rtrim($fields_string, '&');

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);

$result = curl_exec($ch);
curl_close($ch);

Solution 1:

To post as Page not as User, you need the following:
Permissions:

• publish_stream
• manage_pages

Requirements:

• The page id and access_token (can be obtained since we got the required permissions above)
• The current user to be an admin (to be able to retrieve the page's access_token)
• An access_token with long-lived expiration time of one of the admins if you want to do this offline (from a background script)

PHP-SDK Example:

<?php
/**
 * Edit the Page ID you are targeting
 * And the message for your fans!
 */
$page_id = 'PAGE_ID';
$message = "I'm a Page!";


/**
 * This code is just a snippet of the example.php script
 * from the PHP-SDK <http://github.com/facebook/php-sdk/blob/master/examples/example.php>
 */
require '../src/facebook.php';

// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
  'appId'  => 'app_id',
  'secret' => 'app_secret',
));

// Get User ID
$user = $facebook->getUser();

if ($user) {
  try {
    $page_info = $facebook->api("/$page_id?fields=access_token");
    if( !empty($page_info['access_token']) ) {
        $args = array(
            'access_token'  => $page_info['access_token'],
            'message'       => $message 
        );
        $post_id = $facebook->api("/$page_id/feed","post",$args);
    } else {
        $permissions = $facebook->api("/me/permissions");
        if( !array_key_exists('publish_stream', $permissions['data'][0]) ||
           !array_key_exists('manage_pages', $permissions['data'][0])) {
                // We don't have one of the permissions
                // Alert the admin or ask for the permission!
                header( "Location: " . $facebook->getLoginUrl(array("scope" => "publish_stream, manage_pages")) );
        }
    }
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}

// Login or logout url will be needed depending on current user state.
if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
  $loginUrl = $facebook->getLoginUrl(array('scope'=>'manage_pages,publish_stream'));
}
// ... rest of your code
?>

Here the connected $user is supposed to be the admin.

Solution 2:

As far as I know, all you have to do is specify a uid (that is, the page's ID) in your call to stream.publish

EDIT

Have a look at impersonation

Solution 3:

Because the is the only relevant posting in the google results for "facebook graph won't post to page as page" I want to make a note of the solution I found. You need an access token with manage_pages permissions. Then call

https://graph.facebook.com/<user_id>/accounts?access_token=<access_token>

This will list all the pages the user has access to and will provide the access tokens for each. You can then use those tokens to post as the page.
