The Adsense module allows you (the webmaster) to share revenue with content contributing users. You can assign a percentage to share with users. If you have the referral module installed, you can also give a cut to referring users.

On the Killer Aces network, we want to give users credit on their profile pages as well. This requires a little theme hacking.

How to give users Adsense credit on their profile page

Step 1: Allow customization of the profile page

Create a user_profile.tpl.php template file in your theme directory. Here's a basic user profile to get you started. The drupal.org handbook on customizing the user profile has a bunch of handy snippets.

You'll need to add the following overriding function in template.php so the newly created user_profile.tpl.php will be used.

/**
* Catch the theme_profile_profile function, and redirect through the template api
*/
function phptemplate_user_profile($user, $fields = array()) {
  return _phptemplate_callback('user_profile', array('user' => $user, 'fields' => $fields));
}

Step 2: Force the Adsense module to use the adsense_client_id of your choosing

Insert the following code somewhere in user_profile.tpl.php. This overrides the default usage of the site's client id on the profile page.

<?php
  if (module_exist('adsense')) {
    $uid = $user->uid;
    static $client;
    $client = adsense_get_client_id($uid,'blog');
  }
?>

Note: The above code was for Drupal 4.7. In Drupal 5.x, module_exist() becomes module_exists().
