Username match regular expression

[Andy]

If you would like to only allow modern English alphabet, numbers and space in usernames, you can use the "Username match regular expression" field in the admin control panel:

Admin control panel -> Setup -> Options -> User registration

Enter the following:

/^[a-z0-9 ]+$/i

Hello, thanks for this tip.
What is the regex for the same but with accent ? (French)

 

[Andy]

Just add this after the 9.

àâçéèêëîïôûùüÿñæœ

 

[rhody401]

would A-Z also be needed, for uppercase?

No. In this example:

/^[a-z0-9 ]+$/i

the /i part means a case insensitive search.

Thank you very much, very useful.
This is my REGEX for french username

/^[a-z0-9àâäéèêëïîôöùûüÿç\- ]+$/i

i added \- to authorize compound first names which are very common in French, like Jean-Paul.

And I just realized an error in mine. I'm a fool. I wanted to allow dashes and underscores, and am probably allowing a bit too much and not what was intended. No one used it yet. Thank you!
