username contains an invalid character

Client Joined: Oct 07, 2003 Posts: 735 Location: Ohio

I upgraded my site to 3.1 and now when I try to change somebodies username I get:

Quote:

Sorry, but this username contains an invalid character such as '.

I would really like to be able to change usernames like I used to before.

For example before the patch, the username Copeland I was able to change it to Copeland [45th ID], adding a "clan" tag. Now I can't.

How can I fix this.

There may be valid reasons for not allowing spaces and or characters like the brackets you mentioned. Other than bad HTML, I can't think of any at the moment, but if there are no strong reasons, you could probably modify the user administration function to bypass this "error."

Are you using the standard Your Account or an enhanced version (I can't remember).

I was going thru the forum ACP and manage users at the bottom.

Sorry, I meant are you using the standard Your Account module that came with your version of PHP-Nuke, or are you using NSN-YA or CNB-YA?

Standard Your Account

This specific check is only in the Forums Profile

includes/functions_validate.php

Code:




        // Don't allow " and ALT-255 in username.


        if (strstr($username, '"') || strstr($username, '&quot;') || strstr($username, chr(160)))


        {


                return array('error' => true, 'error_msg' => $lang['Username_invalid']);


        }

Removing that code will stop this message, however it may make your site more vulnerable to hackers. Do so at your own risk

There is a seperate check in the Your_Account module
modules/Your_Account/index.php

Code:




function userCheck($username, $user_email) {

This function is what you'll want to edit probably. Again, it may make your site more vulnerable - do so at your own risk

Another option would be to add a parameter to the validate_username function that determines whether to check for characters (and default the value to true), then modify the call to the function from the admin_users function to be false. That would turn off the check only for admins.
