WordPress is a joy to Podcast with – you simply upload your mp3 file, link to it in your post and WordPress takes care of all the other stuff (enclosures, etc.).
I have been using WordPress to publish Podcasts since June of this year without any problems, until recently. The most recent Podcast I published – the RSS for non-techies talk in IT@Cork – failed to show up in my Podcast client apps – either in iPodderX or iTunes.
I checked the RSS tags using the Podcast Feedcheck site only to find the following error “MISSING ITEM ENCLOSURE TAG”
I couldn’t understand why this error would suddenly crop up – all my old podcasts were still showing up, no problem. I disabled plugins, but this didn’t solve the problem so I consulted the WordPress Support site and I found the solution there.
It appears that Archive.org (where the audio file for this Podcast is hosted) use re-directs on their addresses and WordPress can’t add enclosures if it can’t reference the file directly.
The solution –
- In the Write Post screen in WordPress, go to the Advanced section
- There, go to the bottom section labeled “Add a new custom field to this post”
- Where it says, “Key”, type “enclosure”
- Where it says, “Value”, enter the URL of the MP3 you wish to podcast
- Click Add Custom Field
For subsequent Podcasts, choose Enclosure from the Key dropdown in the Advanced posting mode and add the URL of the mp3 as before.
NOTE – this is only necessary if your audio files are being hosted on Archive.org (or any other site which uses re-directs on file names) – for all other Podcasts, it is only necessary to link to the url of the audio file in the post and WordPress will do all the rest.
