The question is: is it my brain? Or Facebook's infuriating API?
Intention: Return my facebook album information and my user information
result: empty data set for album information, full result's for user information
{
"data": [
]
}
<?php
/****************************************************************************
Application settings
****************************************************************************/
$app_id = '123456';
$app_secret = "4543163864";
$my_url = "http://www.myurl.com/app";
$canvas_page = 'http://apps.facebook.com/my_canvas_page/';
# authorize the user using oauth protocol (including required permissions)
$auth_url = "http://www.facebook.com/dialog/oauth?client_id="
. $app_id . "&redirect_uri=" . urlencode($canvas_page)."&scope=user_photos,friends_photos";
$signed_request = $_REQUEST["signed_request"];
list($encoded_sig, $payload) = explode('.', $signed_request, 2);
$fb_user_session = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
# if authorization failed, kick back to auth_url
if (empty($fb_user_session["user_id"]))
{
echo("<script> top.location.href='" . $auth_url . "'</script>");
}
else
{
/****************************************************************************
User successfully logged in.
****************************************************************************/
$my_albums = "https://graph.facebook.com/me/albums?access_token=".$fb_user_session['oauth_token'];
$my_info = "https://graph.facebook.com/me?access_token=".$fb_user_session['oauth_token'];
echo "<a href='$my_albums'>my album information</a><br>";
echo "<a href='$my_info'>my user information</a>";
### ignore this, just testing iframe call ###
exit;
echo("<script> top.location.href='" . $my_albums . "'</script>");
}
?>
Additional information: Testing an 'album' request from http://developers.facebook.com/docs/reference/api/user/ while logged in works! It successfully returns all my album info. But I noticed the authorization token in the test URL is different from my retrieved application token ($fb_user_session['oauth_token']). What is going on here?
Am I missing some kind of authorization step? Why would my application return empty data for my albums using the exact same call & token while Facebook's test call returns a full set? If anyone can help solve this problem once and for all, that would be awesome.
Any ideas?

Try adding "user_photo_video_tags" to the list of scopes requested. Also, try calling the permissions api call to make sure you have access to the user's photos by checking the "user_photos" permission. The url is: https://graph.facebook.com/me/permissions?access_token=...
