Application post to its Wall

Question

I can't find an example of exactly what I'm trying to do, so sorry if this is a repeated question, but I have looked for the last couple of hours.

I want my Facebook app to be able to update a status or post to a wall of a page that I administrate: http://www.facebook.com/amazingjobsapp as part of a CRON job.

I just can't seem to find any examples on how to do this. Any pointers are greatly appreciated.

EDIT:

I've used to code below and now am getting:

object(FacebookApiException)#11 (8) { ["result":protected]=> array(1) { ["error"]=> array(3) { ["message"]=> string(72) "(#200) The user hasn't authorized the application to perform this action" ["type"]=> string(14) "OAuthException" ["code"]=> int(200) } } ["message":protected]=> string(72) "(#200) The user hasn't authorized the application to perform this action" ["string":"Exception":private]=> string(0) "" ["code":protected]=> int(0) ["file":protected]=> string(86)

Can someone walk me through granting my app manage_page and publish_stream permissions for page id 413282938687554 please?

EDIT 2: If I look at my graph.facebook.com/me/accounts then it shows the page id above with an access token but if I use that in my code then I still get the error.

Answer 1

You need to get the manages_pages permission

<?php
$attachment = array(
    'message' => 'this is my message',
    'name' => 'This is my demo Facebook application!',
    'caption' => "Caption of the Post",
    'link' => 'http://mylink.com',
    'description' => 'this is a description',
    'picture' => 'http://mysite.com/pic.gif',
    'actions' => array(
        array(
            'name' => 'Get Search',
            'link' => 'http://www.google.com'
        )
    )
);

// To authenticated user's wall
$result = $facebook->api('/me/feed/', 'post', $attachment);

// To page's wall
$result = $facebook->api('page-id/feed/','post',$attachment);

// To user's wall
$result = $facebook->api('user-id/feed/','post',$attachment);

Answer 2

Ok maybe I missed something in the docs but I found the solution with is as follows:

Note this is for people who are trying to post from a cron job.

• Grant the manage_pages, publish_stream and offline_access perms to your app
• Get the access token for your page from me/accounts in the graph api explorer

• Add one simple line of code just after you initialize your fb object

  $facebook->setAccessToken("XXXXX");
  

Note the access token needs to be the PAGE access token you got from step 2 and remember if you de-auth the app the access token will change.

Answer 3

1. Application will need to ask you for manage_pages & publish_stream permissions.
2. Obtain your pages page_access_token from the graph api /accounts call. Each page you own will have its own token listed. This token can be saved to database or accessed at the time of need. It is not recommended to expose or share this token.
3. Use "php-sdk" to make the post.

refer to: http://developers.facebook.com/docs/authentication/

refer to: http://developers.facebook.com/docs/reference/php/

NOTE: To impersonate the Page when posting to the wall (i.e. post as the Page, and not the current user), you must use a Page access_token with the manage_pages and publish_stream permissions, as described under Page Access Tokens above.

Example: Assumes user has installed and initialized php sdk for Facebook

<?php
if($user){
  $vars = array(
  'message' => "message goes here",
  // you can uncomment below to enable an image with caption and link.
  //'picture' => "image",
  //'link' => "Link here",
  //'name' => "Name here",
  //'caption' => "Caption here",
  'show_error' => true,
  // comment out the access_token array below to post as a user instead of as page.
  array('access_token' => YourPageAccessToken)
);
$testpost = $facebook->api('YourPageId/feed', 'post', $vars);
}
?>

Answer 4

Ok where I had thought we'd fixed it we haven't the post only works when i'm actually logged into the app itself.

I'm using Shawn's code with all the permissions mentioned with the access token from "me/accounts/" for the AmazingJobs Community page.

I've definitely granted manage_pages, publish stream and offline_acess to my own facebook account i then used the graph api explorer to find the access token within accounts and cut and pasted it into my code. Any ideas?
