wordpress - add custom field images to rss feed

[WelshStew]

Hi,

I am using some custom fields in a wordpress installation for images and I would like these added to my RSS2 feed.

I have tried things like Justin Tadlocks plugin, but they still don't appear.
Custom Fields For Feeds: WordPress Plugin

The second part to my query would be to process this feed and only show the images.

Any help appreciated.

[saltedm8]

should be relatively simple as long as the plugin works and is compatible with anything you currently have..

have you created the custom fields ?.. with the proper values etc, they are case sensitive.

seems simple, but that's the first thing I would check ( obviously after checking the plugin is activated lol )

[WelshStew]

yeah, it's all active and the plugin is calling in the same value as the custom field.

Can you highlight the changes you have made and explain them a little so that I know what is going on.

Cheers,

[saltedm8]

this is the first change

 // Place your own four custom fields by replacing the capital text
    if($image == '') {
    $image = get_post_meta($post->ID, 'thumbnail', $single = true);
    } 
  

I am only testing, but it looks like there is a possibility you remove a condition that you may have needed

and this is the second

  // If there's an image, display the image with the content
// Feel free to change the styling of the image border
    if($image == '') { 
  

on this one, I removed the ! just in case it was not an 'if not' .
