Question

i am trying to post into a Facebook Page using PHP.
I have created a Facebook application, and
I am able to post into regular accounts FEED, using the very helpful code i found out in : Daily Automatic post in facebook users wall .

to summarize it does:

$facebook = new Facebook(array('appId'  => 'xxxxxxxx',
                               'secret' => 'xxxxxxxxxxxxxx',));

$post = array('message'   => 'Message to user');

$post_id = $facebook->api("/$USER_ID/feed", "post", $post);

There is no need in any access_token what so ever.
i have granted my application with the following permissions from the PAGE (and from the regular account) : publish_stream,manage_pages

But… this doesn’t seem to work with Facebook PAGE.
i do not seem to be able to post to it from my app.
i have tried the following, and other combinations, but Facebook doesn’t return any error message, nor doesn’t posts:

$feed = '/MYPAGEID/feed';

$post_id = $facebook->api($feed, "post", $post);

Your help is very much appreciated!

Answer 1

In the documentation for the Page object it says:

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

and

To perform the following operations as a Page, and not the current
user, you must use the Page’s access token, not the user access token
commonly used for reading Graph API objects. This access token can be
retrieved by issuing an HTTP GET to /USER_ID/accounts with the
manage_pages permission. This will return a list of Pages (including
application profile Pages) to which the user has administrative
access, along with access_tokens for those Pages. Alternatively, you
can get a page access token for a single, specific, page by issuing an
HTTP GET to /PAGE_ID?fields=access_token with the manage_pages
permission, as described above. Publishing to a Page also requires the
publish_stream permission, unless otherwise noted.

Also, be sure to check the Authenticating as a Page tutorial.
