Aggregate_jcm is a slightly modified version of Rob Miller’s Aggregate which allows you to place the title, link and content of an RSS feed into your posts. This modified version can show the RSS feed content along with the post’ s summary or full text. Live demo here: http://www.jcmiras.net
Installation is done the usual way as we install wordpress plugins, “Download, unzip, upload in wp-content/plugins directory, and activate in your WordPress admin panel”
Then, in your post, add this tag;
where FEED_URL is the url of the feed that you want to aggregate.
If you want to aggregate more than one feed, try to use feedwordpress.
That’s it enjoy!
