Can somebody let me know why the next code isn't being employed as I needed it to. I would like the $token to become placed into ami_st_token_aut of my wordpress_customers area in which the id may be the id from the user presently drenched in.

$token = $_GET['token'];
$services = $_GET['services'];
global $current_user;
$wpdb->query("UPDATE $wpdb->users SET ami_st_token_aut = ".$token." WHERE ID = ".$current_user->ID."");

Look into the $current_user->ID if it's not empty.

When the area type would be to store string values enclose the worthiness in quotes for ami_st_token_aut

$wpdb->query("UPDATE $wpdb->users SET ami_st_token_aut = '".$token."' 
             WHERE ID = ".$current_user->ID."");
