Making a new "view new posts" link that only shows new posts in certain forums?

[Admin]

Next time post this in the same thread please.

Anyway, in search.php find this:

    $datesql=" AND thread.lastpost>=".$bbuserinfo[lastvisit];

    $wheresql="1=1".$forumsql.$datesql;
    $wheresql.=" AND thread.open<>10";

Note: the middle line was changed due to what I helped you with before.
Replace that with this:

    $datesql=" AND thread.lastpost>=".$bbuserinfo[lastvisit];

    if ($newsonly) {
        $wheresql="1=1 AND forumid=XX".$datesql;
    } else {
        $wheresql="1=1".$forumsql.$datesql;
    }
    $wheresql.=" AND thread.open<>10";

Again, the line there is changed in your code.
Change XX to the ID of your news forum, then link to search.php?action=getnew&newsonly=1.
