Look into your JSON data! There is no such property $realid in it!!!

here's how the code look like :
if(isLoggedIn())
{
$username = $_SESSION['userID'];
$database->select("id")->from("users")->where("username", "$username")->query();
$record = $database->fetch_object();
$id = ($record -> id);
$realid = $id - 1;

function data($table){
global $realid;
global $UserData;
$url = "http://localhost/folder/api/$table/$realid";
$json_decode = json_decode(file_get_contents($url));
$UserData = get_object_vars($json_decode[$realid]);
}
data("users");
data("user_data");

?>
"

Congratulations, you are now logged in!

id:

username:

email:

firstname:

"
 }
?>
everything works fine but the only problem i got is the Undefined index for users table " $UserData["firstname"]; " i just want to call the function twice in the same time so i can extract data in the same time from the database ..... thanx
