Integrate Google Ads every X node entries

Hi all.

I thought I would share a simple module I cooked up. I wanted to be able to display a google ads banner beween every five entries on the front page. The way I did it was this:

Modify the node.module

In function node_page_default() I made some changes ....

$output = '';
    $cnt = 0;
    while ($node = db_fetch_object($result)) {
      $output .= node_view(node_load(array('nid' => $node->nid)), 1);
      $cnt++;
     node_invoke_nodeapi($node, 'inbetween', $cnt);
     if ($node->inbetween)
         $output .= $node->inbetween;
 
    }

Create a new module called google_ads.module

<?php

/**
 * Implementation of hook_nodeapi().
 */
function google_ads_nodeapi(&$node, $op='list', $cnt) { 
        if ($op == "inbetween" && $cnt % 5 == 0)
                $node->inbetween = t("
// MY GOOGLE AD CODE HERE
                ");
                return;
        }
}

Then enable the module, and Bob's your mother's brother.
