I have 2 customfields in my wordpress system when creating new posts. 1 called homethumb (is the title of an image) and another called description.
I would like to edit the rss feed so it shows the image and the description rather then the complete post.
But I don't know how to do this. cause I would like to fetch that rss with simple pie to integrate it on another website (sort of autosubmit system)
Custom fields for Feeds Wordpress plugin
Search WP for others.
You also have
do_action('rss_item')
that runs in the loop for every item in the RSS feed. Hook in to that and output anything extra you need in to the feed item.
To show the excerpt instead of the entire article, go to "reading" in Settings section of your admin menu and half way through the options there's a setting to use excerpts instead of full text.
No plugins required. Just a little custom programming.
I found some tutorials on how to add things to your rss reader, so I fixed this.
it's in french -> http://www.webinventif.fr/wordpress-ajouter-du-contenu-dans-son-flux/
Here is another option if you want to display anything other than images and videos in your feed: http://wordpress.org/extend/plugins/rss-custom-fields/
All of your custom fields will now be displayed in your feed.
Further options to be able to select which custom fields display in a feed will be available in subsequent releases of the plugin!
