first of all, thanks for the extension.

I have a requirement, many rating bars on one page.

So i have hacked a version.

Please make this version as the new upstream.
Thanks's Daniel

config.php modifications
PHP Code:

first of all, thanks for the extension.

I have a requirement, many rating bars on one page.

So i have hacked a version.

Please make this version as the new upstream.
Thanks's Daniel

Turns out the Rating Bar extension couldn't find its own config.php AND even after that was resolved, the query syntax was bad (at least for my server).

1) Replace require statements

2) Edit the query statements to include the ` character

    Don't forget to:
    - check every edit before you save it: make sure you understand the text and have NOT changed the meaning
    - check if you're not doing the same edit that you did a few hours ago again: maybe it was reverted and you shouldn't redo it]]>         <![CDATA[Bug with article pages using DEFAULTSORT]]> http://bbs.wiki4games.com/showthread.php?tid=28 Mon, 27 Jul 2009 12:59:43 +0200 http://bbs.wiki4games.com/showthread.php?tid=28 I pointed out a bug with ratings bar, where article pages using the "DEFAULTSORT" call would not appear in w4g_ratinglist top rated lists. Any chance you guys can implement a fix for this? My wiki has switched has over to ratings bar but cannot implement ratingslist because of this bug. Thanks...]]> I pointed out a bug with ratings bar, where article pages using the "DEFAULTSORT" call would not appear in w4g_ratinglist top rated lists.

    Please install this extension: It would make my life alot easier and probably lots of other peoples. Espicially in the early stage of this wiki(I know it isn't that early, but the amount of people viewing here it is.). For instance making those Xbox/Wii Templates ( At the moment i want to do a playstation one but i will wait for this to be installed so i can upload the pics in one shot).
    Thanks,

    Me and cockroach have been having a long chat about this forum you can see it under medals! in general.
    Anyways, I thought I would post one forum software here instead of the medals! thread as it is actually a mediawiki add on.

    Please tell me what you think.
    If you have any other ideas for a forum please post them here.
