XF 1.5 Disable numbers usernames for registration

[Nirjonadda]

How to disable numbers usernames for registration? I want disable registration users with only numbers in username. Example: 1234

I mean the following:

Allow : Nirjonadda or nirjonadda
Allow : Nirjonadda1234 or nirjonadda1234
Disallow : 1234

I want allow numbers in usernames or any characters, but not only numbers.

You could consider using this: Admin - options - user registration - User Name Match Regular Expression

^[a-zA-Z_-]+$

This allows names with a-z, and A-Z and names with underscore _ and dashes -
This won't allow other characters, spaces, or numbers.

That does not do what the OP wanted.

Ooh, I see..
OP is ok with registrations that have numbers in them, but not exclusively numbers.
He needs a regex with a negative look-ahead. I guess: suggestion, not tested
^(?![\d\s]+$)[a-zA-Z\d\s]+$

 

[Nirjonadda]

^(?![\d\s]+$)[a-zA-Z\d\s]+$

What does with this ? we need allow all in all without only numbers

letters and numbers, in pairs, seems to work


numbers and letters, seems to work

pairs of letters, seems to work


pairs of numbers, doesn't seem to work - which is what we want.


letters and numbers stuck together, works fine too


numbers and letters stuck together, works great too


all letters, yep


all numbers, nope, doesn't work - great, it's what we want



So user "bob" can register, and user "123bob" and user "bob123" but not user "1234"

^(?![\d\s]+$)[a-zA-Z\d\s]+$

With this code allow all any characters without only numbers?

user "bob" can register, and user "123bob" and user "bob123" but not user "1234" but Can register with special characters?

a-z,A-Z, doesn't include special characters. Just replace the query with the stuff you want to include. There are a few threads on xenforo that also handle special characters.
