Checking bans for Arcturus 1.16.0

Hello,

I want to update the class.auth.php for checking bans. I used Mercury emulator earlier. In that database, you had the value table which can include a username or an IP.

Now, Arcturus works with a user_id, which only can include a user ID. For the IP checking I use the table IP; that seems to work. But there is no table to use for username check.

So, I need something that converts usernames to user IDs.

I currently have the following

PHP Code:

---

    private function isBan($username){
    global $config ;
            $data = $this->_db->query("SELECT * FROM bans WHERE user_id = '".$username."' OR ip ='".$_SERVER['REMOTE_ADDR']."' LIMIT 1",true,false);    
            if($data){
                if(time() > $data['expire']){
                    $req = $this->_db->query('DELETE FROM bans WHERE id='.safe($data['id'],'SQL'));    
                    return false ;
                }
                else{
                    $this->logout();
                    redirection($config->url_site.'/index.php?ban='.$data['id']);
                }    
        }
    } 


---

I need something like the following:

PHP Code:

---

SELECT id FROM users WHERE mail = '".$username."' 


---

But when I add something like that, I get 'Resource id #45' as user ID.

Hope you can help. Thanks in advance for the assistance.

Solved. Changed username to uid on the bottom of the file.
