Topic: [A-Z][a-z] and [0-9] usernames only, need help with register.php

The thing I wanna do is to change so only usernames with [a-z][A-Z] and [0-9] are allowed.

Though my problem now is the register.php, I'm trying to find out where it exits if e.g. the username is already in use.
As I read the register.php now the user will be registered(inserted into the database) even if something is wrong. This is not the case
so if anyone can help, it would be appreciated.

Re: [A-Z][a-z] and [0-9] usernames only, need help with register.php

In register.php, there are a number of rows of code that check the validity of the username. The code starts after the comment:

// Validate username and passwords

In there, you could add something like this:

if (preg_match('/[^a-zA-Z0-9]/', $username))
    message('Usernames must only contain bla bla...');

I'm tired, so the regex might be broken smile
