Change Username Hack

[Scott MacVicar]

I wrote a small modification to allow users to change their usernames, they can change their username ok and post at the forums etc.

BUT when they go to view a forum where only admins and moderators can post they get the standard No Permissions or You need to be registered error.

[Dennis Wrenn]

Well, that's perfectly normal. If the forum is only for Administrators and Moderators, then they shouldn't be allowed to view it.

Do you want them to be able to view - but not post in the forum?

sorted now

i had it set on private forum =/

Can you release your hack?
It sounds nice, and very useful.

[Scott MacVicar]

Instructions are in the file. Isn't too hard to install.

If you need any help just post back here.

Look at http://vbulletin.com/forum/showthrea...threadid=24722 latest verion from there

If a user has...say....20 posts, and they go and change their username, do all their posts automatically update with the new username? If you have a members only board with a lot of members and you have several members changing their usernames, you're probably going to have problems with posts having invalid usernames, etc., unless you periodically update user info, post counts, etc., via the Admin CP.

The user's ID does not change. Everything the user has posted before is associated with his ID, including his username.
So yes, all of past posts and everything else will have the new username.

[Scott MacVicar]

Nope, only the user ID is stored in the thread table not the Username. So when the username changes, it changes it for all posts made by the user.

I get the following error after applying the hack to member.php:

Parse error: parse error in /---removed---/member.php on line 1298

I am using 2.0.3 so I'm not sure if that's the problem.

Dimitri, this is the code you will need to paste:

PHP Code:

  if ($username != $bbuserinfo[username]) {
    $username = trim($username);
    $username = eregi_replace("( ){2,}", " ", $username);
    if ($checkuser=$DB_site->query_first("SELECT username FROM user WHERE username='".addslashes(htmlspecialchars($username))."' OR username='".addslashes(eregi_replace("[^A-Za-z0-9]","",$username))."'")) {
      eval("standarderror(\"".gettemplate("error_usernametaken")."\");");
      exit;
    }
    }
    else {
      $DB_site->query("UPDATE user SET username='".addslashes(htmlspecialchars($username))."' WHERE userid='$bbuserinfo[userid]'");
      $bbuserinfo[username] = $username;
    } 


PPN forgot to close one IF statement.
