The items inside the feed have the order DESC, the newest item is on the last position. Maybe you reorder this feed in Pipis.
Hello Frank,
I have reversed the sort order of my yahoo feed. It is now set to descending in the pipe. I am seeing no change in the displayed feed on my website. I believe I have also been able to clear the simplepie cache as well just to be sure.
Perhaps my issue is specific to my WordPress 3.7.1 install.
My research has determined that the SimplePie class defaults to a reverse chronological order sort as documented here:
http://simplepie.org/api/class-SimplePie.html
enable_order_by_date( boolean $enable = true )
I then determined that the SimplePie object is created in wp-includes/feed.php
The parameters for the SimplePie object are specified in the function ‘fetch_feed’.
I added:
$feed->enable_order_by_date(false);
My feed was immediately displayed in the desired chronological order.
Now that I have made this code modification, changing the sort order in my yahoo pipe does in fact change the order displayed on my site.
Thanks for the feedback, intresting.
