[SOLVED] Problem with username starting with number

Hello,

By accident, I noticed something strange today when I was trying to change a certain user's access level.

Every time I try to save the changes to his account (in the backend), I get "invalid input" for the username.
So I went to check the CB settings for usernames, and the validation rule for that field is set to "Single Alphanumeric Word (letters, numbers and underscores only)".

The username of that member contains only of letters (both uppercase and lowercase) and numbers, nothing else. So there should not be a conflict.

However, their username begins with numbers. When I remove the numbers at the beginning of the username and move them to e.g. after the letters, then it is no problem anymore. So it would seem that CB is refusing to accept that username simply because it begins with numbers.

Could this be a bug, or do I need to change a setting?

Thanks!

That validation rule expects the value to start with a letter. It's expecting an actual alphanumeric word. Beginning with a number isn't really a word. If you want it to validate only letters and numbers and doesn't care about it being an potential word you can use the following custom validation rule.


To also accept underscores you'd use the below.

Hello,

Thanks for your fast reply.

I changed the settings as per your suggestion, and now it works! Thanks!
