extern.php with rss 2.0

If there isn't one knocking about, I'll try and backport the one I use for you. It has latest message/topic selectable display.

Have posted both the Atom and RSS generators up, so you have the choice of either/both:

There is a langfile to go in lang/English/, a feed_functions.php file to go in include/user/, and then the two atom.xml and rss.xml files to go in the root forum dir. The scripts are call via one of four parameters:

[path/to/forum/]atom.xml?cid=[category id]
[path/to/forum/]atom.xml?fid=[forum id]
[path/to/forum/]atom.xml?tid=[topic id]

The fourth one is for if you are running the sub-forum mod. It will generate a feed for all of the child forums of a parent forum:

[path/to/forum/]atom.xml?pfid=[parent forum id]

These are feeds on the test forum:

Edit: Obviously, change atom.xml to rss.xml above if you're using the RSS feeds.

I have uploaded all the files. It still gives the error for each of that code in echo.

echo '<?xml version="1.0" encoding="'.$lang_common['lang_encoding'].'"?>'."\n";
    echo '<?xml-stylesheet type="text/css" href="'.$forumuri.'style/feeds/rss.css"?>'."\n";
    echo '<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">'."\n\n";
    echo '<channel>'."\n";
    echo '<title>'.pun_htmlspecialchars($pun_config['o_board_title']).'</title>'."\n";
    echo '<link>'.$forumuri.'</link>'."\n";
    echo '<description>'.pun_htmlspecialchars($pun_config['o_board_title']).'</description>'."\n";
    echo '<language>'.$language.'</language>'."\n";
    echo '<docs>http://backend.userland.com/rss</docs>'."\n";
    echo '<atom:link href="'.$atomdir.basename($_SERVER['PHP_SELF']).$add.'" rel="self" type="application/rss+xml"/>'."\n";
    echo '<ttl>60</ttl>'."\n\n";

I've uploaded a newer version of those scripts now, btw. The main alterations are use of the Etag header for modified/not modified status codes to the browser, and some general code trimming/optimising. One thing to note. I've set these scripts up for mysql seeing as that seems to be the general db type in use, so any pgsql users will need to alter these two lines:

//pg_result_seek($result, 0);
mysql_data_seek($result, 0);

by commenting out the mysql line and removing the comments from the pgsql line.

The download is still at the same location:
