Lots of previous threads for this. Even a recent one with a Trac ticket to make it so it doesn’t require lowercase:
Thanks for the reply – indeed I will try the Track ticket
Does anyone have a solution for this problem? Is it possible to be allowed in capital letters in usernames? All the Links on Google and buddypress.org doesn´t help…
I have tryed out a few things… For example, I’ve replaced in the bp-core-signup.php on line 321
preg_match( "/[a-z0-9]+/", $user_name, $maybe );
preg_match( "/[a-zA-Z0-9öäüÖÄÜß]+/", $user_name, $maybe );
In line 327 an error message is generated when the user name does not comply with certain criteria.
if ( !validate_username( $user_name, $strict = false ) || in_array( $user_name, (array)$illegal_names ) || $user_name != $maybe )
$errors->add( 'user_name', __( 'Only lowercase letters and numbers allowed', 'buddypress' ) );
When I comment out followed code in Line 327:
!validate_username( $user_name, $strict = false ) ||
my preg_match rule works with the capital letters and special characters, but I think that will later have an impact on the log on and other things.
Capital letters are now being accepted, but no special characters such as “ßöüÖ” … -.-
validate_username() is a WordPress function
and it uses
sanitize_user() which is documented here:
Has anyone any idea how to do this without an sql injection or incompatible usernames later?
I would have liked that a user can log in as “SteffanieKönig” …
When we get together at a solution I would like to summarize the whole issue and as a plugin, but I’m at the end of my knowledge! -.-
Maybe someone has an idea?
You should update this trac ticket with what you’ve tried: https://trac.buddypress.org/ticket/2207 I assume that’s where you got the code to try.
You can log into trac with the same user you log in to this forum with.
Thanks @crashutah ! I would do this!
