Auto-unpublish in the back end when page date field is older than N?

[MarcC]

I have this task:

For any page with "event" template and a date field that is showing a date older than date N, unpublish the event.

I need this to happen fairly regularly--is this a good task for lazy cron?

Thanks!

Hi MarcC,

maybe this module could be useful:

Thanks Alessio!

Just add something like this to the top of your events index page. You could compartmentalize this into a LazyCron call, but for such a simple thing it's really not necessary. 

$events = $pages->find('parent=/events/, date<"-3 months"'); 
foreach($events as $event) {
  $event->of(false);
  $event->addStatus(Page::statusUnpublished); 
  $event->save(); 
}

Btw, when testing something out like this, always comment out the $event->save(); the first time and take a look at what pages get affected by echoing them rather than saving them, the first time around. i.e. 

// $event->save();
echo "<p>Unpublishing: $event->url</p>";

Once confirmed that it is behaving the way you want, then remove the echo and uncomment your save();

Nice one, Ryan! Thanks for the tip on echoing before save, too.
