Do you want to count access statistics for anonymous visitors only? Do you want to reset access statistics for unpublished articles?
I'm assuming you're using the Drupal 7 statistics module.
Instead of copying the whole statistics module and changing it, there's a simple trick: Undo the +1 of registered users by an -1. Thus, the increase of the statistics module is compensated.
<?php/** * Implements hook_exit(). * * Compensate access statistics of registered users with -1. * See statistics_exit(). */function YOUR_MODULE_exit() { global $user; // When serving cached pages with the 'page_cache_without_database' // configuration, system variables need to be loaded. This is a major // performance decrease for non-database page caches, but with Statistics // module, it is likely to also have 'statistics_enable_access_log' enabled, // in which case we need to bootstrap to the session phase anyway. drupal_bootstrap(DRUPAL_BOOTSTRAP_VARIABLES); if (variable_get('statistics_count_content_views', 0)) { // We are counting content views. if ($user->uid != 0 && arg(0) == 'node' && is_numeric(arg(1)) && arg(2) == NULL) { // A node has been viewed, so update the node's counters. db_merge('node_counter') ->key(array('nid' => arg(1))) ->fields(array( 'daycount' => 1, 'totalcount' => 1, 'timestamp' => REQUEST_TIME, )) ->expression('daycount', 'GREATEST(daycount, 1) - 1') ->expression('totalcount', 'GREATEST(totalcount, 1) - 1') ->execute(); } }}?>
Additionally, it's possible to reset node access statistics of unpublished articles with each cron run.
<?php/** * Reset counts of unpublished nodes. * Implements hook_cron(). */function YOUR_MODULE_cron() { if (variable_get('statistics_count_content_views', 0)) { // Reset counts of unpublished nodes. $unpblished = db_select('node', 'n') ->condition('n.status', 0, '=') ->fields('n', array('nid')); db_update('node_counter') ->fields(array('daycount' => 0, 'totalcount' => 0)) ->condition('nid', $unpblished, 'IN') ->execute(); watchdog('ibexutils', 'Reset counts of unpublished nodes.', array()); }}?>
