Inject adsense ads into node content automatically.

Code

function adsense_injector_nodeapi(&$node, $op, $teaser, $page) {

    return;
  }

  // insert an ad into the body.

      // Get the minimum node body wordcount for insertion.
      $minwords = variable_get('adsense_injector_body_view_minwords', 75);

      // Count words in a string.
      // lifted from node.module node_validate() function.

        // Process adsense module tags in the template text, if enabled and possible.
