Stop Allowing Spaces in User Names?

[kau]

I don't want new registers to be able to use spaces in their user name. Like;

John Williams

Is that possible without hacking vB?

Admin CP -> vBulletin Options -> User Registration Options -> Username Regular Expression

Use this regex:

^([a-z]|[0-9])+$

That will allow only alpha characters and numbers.

What if I want to allow symbols like;

John_Williams
John+Williams
John.Williams
JohnWilliams!
John-Williams

I don't know the regex for that. If no one else here is able to help you with that then you can also try posting on www.vbulletin.org.

Ask to modifiy this string or just tell them what you want.

(?-i)(?=^.{8,}$)((?!.*\s)(?=.*[A-Z])(?=.*[a-z]))(?=(1)(?=.*\d)|.*[^A-Za-z0-9])^.*$

I have a similar question, except I ONLY want people to register with a space between their first and last name.

So for me, John Williams would be valid, whereas JohnWilliams or John_Williams would not be.

Thanks

I know it starts to work at requiring an underscore, but I need to modify this regex more so that it works with all names. There seems to be some very complex cases to deal with including Leonard_McCoy which would pass mine, but fail on a basic string that allowed for

([A-Z][a-z]+[_][A-Z][a-z]+)

I just need a basic filter to make sure the users submit namefirstorlast_namefirstorlast

Gave up on this a long time ago... but to combat SPAM registrations, started looking into it again. I found one, and modified it to suit my needs. Thought I'd post it here incase anyone else is running a real name board.

^([A-Z][a-z]+)(\s|\-)([A-Z][a-zA-Z-]+)?(\s|\-)?([A-Z][a-zA-Z-]+)?$

This allows:

Jane Doe
Jane Doe-Smith
Jane Doe-Smith Jr
