vanilla 2.1b2

you can change the validation:

e.g. would only allow lower-case letters in name.

$Configuration['Garden']['User']['ValidationRegex'] = '[a-z]';

only allow what you want in your regular expression.

peregrine

you could also override function by creating your own ValidateUsername...

if (!function_exists('ValidateUsername')) {
   function ValidateUsername($Value, $Field = '') {
      $ValidateUsernameRegex = ValidateUsernameRegex();

      return ValidateRegex(
         $Value,
         "/^({$ValidateUsernameRegex})?$/siu"
      );
   }
}




you can also change the min and max length by 

minimum 5 and max 10

$Configuration['Garden']['User']['ValidationLength'] = array(5,10)

peregrine

and the requisite change to your definition of the message generated by validation error.

e.g.

$Definition['UsernameError'] = "only lowercase letters allowed";

from a UI perspective you need to add a validation expression to the username field of the account creation form.

@jeongwee
from a coding perspective, if you post questions without expressing your vanilla version, you will not only continue to give a bad example for future people who can't read the message at the top of the forum , but it will prevent people from trying to help you with the exact version you are using.

Granted, there are some people who insist the discussion question MAY not or DOES not require your vanilla version, BUT it certainly can't hurt, and it can only help. It may be the same answer no matter what version of vanilla you are using, but it will rule out the possibility of multiple answers or the wrong answer based on assumption of vanilla version which may be incorrect.

Sometimes consistency in ALWAYS providing vanilla version with question, can be an advantage.

**Message at top:

" When posting a question on the forum, please include the version number of Vanilla you are using."**

k, k no apology necessary. proof will be when you post your future questions.

= = sry man...im dumb always forgot to tell version :O

i wrote it into my name title ,so even if i still forgot it next time, ppl will see my version

also if you can take a look at this http://vanillaforums.org/discussion/24707/symbloeditor-feedback#latest

the reason i don wanna let username inlucde like "_" becoz it wont work with symboleditor, user have to change the link manually.

sorry, only advice is free. there are lots of examples of form validation in existing plugins. otherwise see "Custom Plugin Development" in my signature.
