Comments

Great tutorial. Would you be so kind as to tell me what I would put into the PHP code field if I wanted, say, to update URL aliases (using pathauto and token) once new content was created?

I do not see where to put the php code indicated in step 13. The rest of the steps worked.

Make sure that you have enabled the "php filter" module in admin/build/modules. In Drupal 6 it is disabled by default.

You can also use Elysia Cron module (http://drupal.org/project/elysia_cron) for managing specific cron jobs and have them run at what ever frequency you'd like. Having them run less than realtime may also take load off the server when people add and edit nodes at a high frequency.
