Enhanced RSS Feeds

[mystermarque]

I have changed the code in PostRssFunctions.php but still Images are not visible

Xcitezone, you'll need to provide more information about your setup. But first, here's 2 things you could try:

1. Make sure you "clear all caches" in the admin
2. If you're using Feedburner for your feeds, you'll need to go to their "Troubleshootize" page and click the Resync Feed button at the bottom.

first check the site http://hotlinks.xcitezone.com
I cleared all the caches in Admin and I am not using feedburners for feeds

Seems fine from what I can tell. Maybe you should post your PostRssFunctions.php for us to have a look at.

Also, consider redirecting your feed through Feedburner. It's a good service, provides subscriber stats, plus I've only tested my RSS image code whilst using them. Though, in theory, it should work without.

xcitezone,

Try using my fix AS IS first and see if it works. You can then modify it to suit your needs from there.

It looks as though you're trying to ONLY display images with no description - which should be possible - but you're using double quotes in your code which would probably pull errors.

Hey Mark,

Is there any way to also allow for a thumbnail of the videos to be displayed in the rss feed?

Thanks

Nick, you beat me to it! I was just about to post a solution I hacked together last night. I'll put it here anyway as I've tested it and it works. I just tried yours on Hotaru 1.4.1 and it's pulling errors for some reason.

Replace (near bottom of PostRssFunctions.php):

$item['description'] = $result->post_content; 

With the following:

$item['description'] = '<a href="' . $h->url(array('page'=>$result->post_id)) . '"><img src="' . BASEURL . 'content/images/post_images/' . $result->post_img . '" title="' . $result->post_title .  '" alt="' . $result->post_title . '"></a><p>' . $result->post_content . '</p>'; 

Cheers,
Mark.
