I don't know offhand of regex that will only trim/leading trailing spaces. :)

I've done some research and the only thing that Username expressions eliminates is the ability to create new accounts with trailing spaces. What I want to do is eliminate that ability to login to pre-existing accounts with trailing spaces as well.

Please advise,

Yes, leading/trailing spaces are trimmed automatically upon registration. I have no idea how users were able to register with trailing spaces.

You will likely have to manually edit the offending usernames, and send the users an email to advise them of the change to their username.

This is the really weird thing. So, there are no spaces in anyone's username, and yet, they are still able to login when using a space in their name. Like let's say your account name is johndoe16, you can login just fine if your type in "johndoe16 " And this is the case for infinite spaces.

Please advise,

Yes, you can type in trailing spaces when you log in, but those spaces do not change the actual username in the database.

But that is the issue. How do I stop those those trailing spaces at login? I use this authentication script to be able to allow members to connect to a gameserver and with the trailing spaces, they can bypass the character limits by creating ghost accounts, thereby having unlimited player characters.

I need to be able to stop this.

Any advise,

When I login to my dev site, and look at the username retrieved from the login form ($vbulletin->GPC['vb_login_username']) it has already been trimmed of any leading/trailing spaces.

Then I suppose its not possible. Okay, fair enough. Thanks for trying.

How are your users logging onto the game server...are they required to manually enter their username?

They enter their username and password into the game and the game pings the auth.php file on the webserver and depending on the response, it either logs you in, says wrong information or says you've been banned.

Okay, then the code used for the game login would have to be edited to trim the usernames entered. :)

This is what I sent to vBulletin.com Support:

And this is the response I got:

When I asked which file I needed to modify, they basically stated that I needed to ask over here because it dealt with modifying the original code.

Anyhow, any insight?

Can you give a link to the vBulletin product you are using for the game server login?

I would speak to the owner(s) of that site then, as the issue would likely have to be addressed by them.
