Cannot post entry to facebook fan page wall as an admin - php

Question

I am trying in vain to post to a Facebook fan page wall as admin. I want to post new entries with pictures, link, description etc on my fan page wall. This is integrated into my custom cms so that whenever a story is updated on my website, it automatically posts the same on the fan page wall.
The problem is that whenever I post, the post does not appear as posted by admin. It appears as posts by others on the right side of the timeline.
How do I go around the following code so that it posts as admin on my fan page wall? I been looking at it for two days, checked similar stuff on the web and so, but I still cant seem to crack it. Help will be appreciated.
$page_id = 'xxxxxxxxxx';
$article_link = "http://xyz.com/articles/headlines/title-one/";
$result = $facebook->api("/me/accounts");
foreach($result["data"] as $page) {
if($page["id"] == $page_id) {
$page_access_token = $page["access_token"];
break;
}
}
$og_title = "Sample title";
$og_image = "http://xyz.com/images/articles/919161344090182.jpg";
$msg = "some description of the article";
$feed_array = array(
'access_token' => "$page_access_token",
'message' => "$msg",
'picture' => "$og_image",
'link' => "$article_link",
'name' => "$og_title",
'caption' => "$og_title"
);
try {
$page_post = $facebook->api("/$page_id/feed","post",$feed_array);
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}

If you want to post as the page - that means that the post will appear as if the page posted an update as it appears here :
Then you will have to use a valid page access token. There is information on how to obtain this kind of token in the Facebook Authentication Documentation. It looks like you already have a token in your code - you can test it using the Facebook Debugger and see if it is still valid.
Another thing you may want to try, instead of appending the token to be one of the parameters of the post array, you could use the setAccessToken() function of the PHP SDK. More details can be found here - https://developers.facebook.com/docs/reference/php/facebook-setAccessToken/
$facebook->setAccessToken($new_access_token);
As a final BTW note, when you specify elements of an array, unless you are wanting to specifically add the quote character, there is no need to wrap the values in quotes.
$feed_array = array(
'access_token' => $page_access_token,
'message' => $msg,
'picture' => $og_image,
...
);
If you want to explicitly add quotes to the values you would have to do something like this -
$feed_array = array(
'string_value' => '"'.$value.'"',
...
);
