Problem with posting to Facebook Page using PHP script as Page account - php

Question

I am using the following PHP code to post to my page wall. it is okay I can post successfully as admin but I want to post to the wall using the page name (page account). how do I post using the page name or page id. I tried to find good resource to explain Facebook API function but i did not find good documentation for it.
<?
require '../src/facebook.php';
$app_id = "XXX";
$app_secret = "YYY";
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true
));
$user = $facebook->getUser();
//echo $user;
if(($facebook->getUser())==0)
{
header("Location:{$facebook->getLoginUrl(array('req_perms' => 'user_status,publish_stream,user_photos,offline_access'))}");
exit;
}
else {
echo "i am connected";
}
$attachment = array('message' => 'this is my message',
'name' => 'This is my demo Facebook application!',
'caption' => "Caption of the Post",
'link' => 'example.org',
'description' => 'this is a description',
'picture' => 'http://example.org/image.gif',
'actions' => array(array('name' => 'Get Search',
'link' => 'http://www.google.com'))
);
$status = $facebook->api('/123456789/feed', 'POST', $attachment); // my page id =123456789
?>

I found the solution to the problem.
To post or to do any task as a page , you need an access token.
Here is my final code after the update, I want to share it with you because I found many people having difficulty with getting the correct access code for a page.
<?
require '../src/facebook.php';
$app_id = "XXX";
$app_secret = "YYY";
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true
));
$user = $facebook->getUser();
//echo $user;
if(($facebook->getUser())==0)
{
header("Location:{$facebook->getLoginUrl(array('req_perms' => 'user_status,publish_stream,user_photos,offline_access,manage_pages'))}");
exit;
}
else {
$accounts_list = $facebook->api('/me/accounts');
echo "i am connected";
}
//to get the page access token to post as a page
foreach($accounts_list['data'] as $account){
if($account['id'] == 123456789){ // my page id =123456789
$access_token = $account['access_token'];
echo "<p>Page Access Token: $access_token</p>";
}
}
//posting to the page wall
$attachment = array('message' => 'this is my message',
'access_token' => $access_token,
'name' => 'This is my demo Facebook application!',
'caption' => "Caption of the Post",
'link' => 'example.org',
'description' => 'this is a description',
'picture' => 'http://example.org/image.gif',
'actions' => array(array('name' => 'Get Search',
'link' => 'http://www.google.com'))
);
$status = $facebook->api('/123456789/feed', 'POST', $attachment); // my page id =123456789
var_dump($status);
?>

My Facebook OAuth is a little rusty, but I believe this will help:
http://bugs.developers.facebook.net/show_bug.cgi?id=10005
It is the exact bug you are describing, but I have no way of testing that it corrects the issue specifically.

This should help: http://developers.facebook.com/docs/reference/api/page/#feed
It looks like you need the manage_pages permission.
