well http://www.gerd-riesselmann.net/archives/2005/11/display-related-nodes-i... has a great hack which I had used on 4.7 some years back but now I am trying to use it and its not working. Here is the code -
<?php if ($page != 0)
{ $words = search_index_split($node->title);
$searchArgs = "";
foreach($words as $word)
{
if (strlen($word) > variable_get('remove_short', 3))
{
if (!empty($searchArgs))
{ $searchArgs .= " OR "; }
$searchArgs .= $word . " ";
}
}
if (strlen($searchArgs) > 0)
{
$results = node_search('search', $searchArgs);
if (is_array($results) && count($results) > 0)
{ print '<hr />';
print '<div id="related_nodes">';
print '<h2>The following articles may be of interest to you, too:</h2>';
$list = array();
$count = 0;
foreach($results as $item)
{
if ($item['title'] == $node->title)
{ continue; }
$list[] = l($item['title'], ltrim($item['link'], '/')) .": " .strip_tags($item["snippet"]);
if (++$count > 4) { break; }
} print theme("item_list", $list);
print "</div>";
}
}
} ?>i am trying to use it for a content type how2 by putting it in node-how2.tpl.php file but its not working. so I put it in node.tpl.php and still the code is not working, for any content type. Any idea what is going wrong here ?
anyone ?
Nevermind, I got it working. The code is fine :)
