I'm not a coder but I managed, through trial and error, to get an external RSS feed to display within a scrollable table on forumdisplay. I have several different feeds displayed on separate forums.
Examples:
http://www.world-a-team.com/forumdisplay.php?f=3
http://www.world-a-team.com/forumdisplay.php?f=4
http://www.world-a-team.com/forumdisplay.php?f=7
Each separate feed requires a pair of files uploaded to your server. A php and html file. The php file contains the feed URL.
eg: $XMLfilename = "http://www.cricinfo.com/rss/wc_2007.rdf";
The HTML file contains variables that get replaced by different parts of the feed. The php file addresses the html file.
eg: $TEMPLATEfilename = "rsswc.html";
In the phpinclude_start template I use
ob_start();
require("rssaus.php");
$rssaus = ob_get_contents();
ob_end_clean();
to create a variable - eg: $rssaus which I place in a conditional in the forumdisplay template.
eg:
$header
$navbar
<if condition="$foruminfo['forumid'] == 3">$rsseng</if>
<if condition="$foruminfo['forumid'] == 4">$rssaus</if>
<if condition="$foruminfo['forumid'] == 5">$rsssaf</if>
<if condition="$foruminfo['forumid'] == 6">$rsspak</if>
<if condition="$foruminfo['forumid'] == 7">$rssind</if>
So I can display a different feed on different forums.
