Since I couldn't find anything with regards to a related content module I decided to modify the anynews module to serve my needs.
Its very basic for now and is called with relevant_content(); in a code section or inside the template with the full PHP tags.
The code looks at the page_title and page_keywords to create the results so even if you dont have keywords on the page it will still return some results.
I added the code into the anynews module. I recommend adding the following code to your include file instead of using my anynews module. It has been hacked to suit my needs.
if (!function_exists('relevant_content')) {
function relevant_content($group_id=0, $max_news_items=10, $max_news_length=6, $display_mode=2, $header_text="",
$readmore_text="read more", $no_news_text="No related content...", $strip_tags=true) {
// group_id... group from which you want to read news from (default:= 0 for all groups)
// max_news_items... maximal number of news shown (default:= 10, no value >10 accepted)
// max_news_length... maximal length of the short news text shown (default:=-1 for full news length)
// display_mode... 1:=details (default); 2:=unsorted list
// header_text... heading text shown (default:="Latest news")
// readmore_text... text displayed for readmore link (default:=read more)
// no_news_text... text shown if no news available (default:="no news avaialbe yet...")
// strip_tags... true:=remove all PHP/HTML/JS tags from string inputs (default); false:=don´t strip tags
// register outside object
global $database;
// convert all numeric inputs to integer variables
$group_id = (int) $group_id;
$max_news_items = (int) $max_news_items;
$max_news_length = (int) $max_news_length;
$display_mode = (int) $display_mode;
$strip_tags = (bool) $strip_tags;
// do some sanity checks of arguments passed by the user
if($max_news_items > 9 || $max_news_items < 1) {
$max_news_items = 10;
}
if($max_news_length < -1) {
$max_news_length = -1;
}
if($display_mode < 0 || $display_mode > 2) {
$display_mode = 1;
}
// strip tags if specified
if($strip_tags) {
$header_text = strip_tags($header_text);
$readmore_text = strip_tags($readmore_text);
$no_news_text = strip_tags($no_news_text);
}
// query to obtain news items for the selected group
//get Current Page Keywords for related content.
if ($group_id < 1) {
$sql = 'page_title="impossiblenametoguess"';
$keywords = explode(" ",PAGE_TITLE);
foreach ($keywords AS $k=>$v) {
$v = eregi_replace("&", "", $v);

I take no responsibility for this code and I recommend you make a backup of all the files you plan to modify. Use at own risk.
