How can I stop users from creating user names like this?

You can use regular expressions

First go to app/ and open class.users

Find this function:

Code:

---

final public function validName($username)   
    {
        if(strlen($username) <= 25 && ctype_alnum($username))       
        {           
            return true;       
        }                 
       
        return false;   
    } 

---

and replace that with this:

Code:

---

final public function validName($username) 
{
    if(strlen($username) <= 25 && preg_match("/^[a-zA-Z0-9]+$/", $username)) 
    {         
        return true;       
    }             

    return false; 
}

That code ^ only allows A-Z and numbers, you can change it to and have people still sign up with "-" if you'd like, you would just have to change the "/^[a-zA-Z0-9]+$/" to something else.

Code:

---

final public function validName($username) 
{
    if(strlen($username) <= 25 && preg_match('/[^\w-]/', $string)) 
    {         
        return true;       
    }             


    return false; 
}

---

underscore, dash, alphanum
