I am using php-sdk for showing facebook information of the user. I have successfully shown the user profile info but while fetching any album or photos I am getting the blank data to me. I read the photos requires access_token. Also if I put this query in the facebook graph api explorer it showing me the perfect result. So query is right may be my way of passing the url is wrong.
I am not getting the issue. Please help. '; $app_secret = ''; $my_url = '';
$config = array(
'appId' => '<appid>',
'secret' => '<appsecrete>',
);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
$code = $_REQUEST["code"];
if($user_id) {
//auth user
if(empty($code)) {
$dialog_url = 'https://www.facebook.com/dialog/oauth?client_id='
. $app_id . '&redirect_uri=' . urlencode($my_url) ;
echo("<script>top.location.href='" . $dialog_url . "'</script>");
}
//get user access_token
$token_url = 'https://graph.facebook.com/oauth/access_token?client_id='
. $app_id . '&redirect_uri=' . urlencode($my_url)
. '&client_secret=' . $app_secret
. '&code=' . $code;
$access_token = file_get_contents($token_url);
$fql_query_url = 'https://graph.facebook.com/'.'fql?q=SELECT+pid,src_small+FROM+photo+WHERE+aid+IN+(SELECT+aid+FROM+album+WHERE+owner=+me())&'.$access_token;
$fql_query_result = file_get_contents($fql_query_url);
$fql_query_obj = json_decode($fql_query_result, true);
//display results of fql query
echo '<pre>';
print_r("query results:");
print_r($fql_query_obj);
echo '</pre>';
}
?>
One parameter needs to be add for $dialog_url variable which is 'scope' which defines permissions to be given for application
$dialog_url = 'https://www.facebook.com/dialog/oauth/?client_id='.$app_id.'&redirect_uri='.urlencode($my_url).'&scope=user_photos';
echo("<script>top.location.href='" . $dialog_url . "'</script>");
