Get last modified date ona published object in PHP

Wednesday 19 November 2003 10:28:50 am

I need to find out when a content object was last modified with a PHP script (kernel/content view.php to be specific). I have tried a couple of methods but have not been able to generate the proper date. I have a feelign any "solution" that I come up with will be ugly and probably much more complicated than the right way.

I am trying to set the Last-Modified header for each document to the date and time that the content object was modified.

I would truly appreciate any help!

In fact, you can copy the header being sent in index.php. That would format the timestamp as a GMT date/time.

header( 'Last-Modified: ' . gmdate( 'D, d M Y H:i:s', $object->attribute('modified') ) . 'GMT' );

This will send a Last-Modified header in the format: Wed, 18 Nov 2003 18:54:19 GMT (but then with your timestamp converted to the GMT timezone).

That's weird. I tested the code on my local install and it works fine.

Of course, $object means the name of the variable that holds your content object.

Just did another test (just printing it in kernel/content/view.php) with the code:
gmdate( 'D, d M Y H:i:s', $object->attribute('modified') )

The result of that code (on my content object) is:
Mon, 29 Sep 2003 18:43:36

EDIT: I just noticed there's a typo in my post above. It said 'modifed' instead of 'modified'. I should learn to always use copy/paste instead of typing it again ;) Sorry for that.
