$sql = "SELECT * FROM users WHERE username='$u' AND activated='1' LIMIT 1";
$user_query = mysqli_query($db_conx, $sql);
// Fetch the user row from the query above
while ($row = mysqli_fetch_array($user_query, MYSQLI_ASSOC)) {
$gender = $row["gender"];
}
// Ajax calls this REGISTRATION code to execute
if(isset($_POST["f"])){
// CONNECT TO THE DATABASE
// GATHER THE POSTED DATA INTO LOCAL VARIABLES
$f = preg_replace('#[^a-z0-9]#i', '', $_POST['f']);
