Audio RSS enclosure problem

[bryan868]

So I have a client with a website for their podcast. To make it easy, I just have them upload their audio file to a post, then I use get_children to grab the audio attachment and display it where I want on the page. That way they don't have to deal with custom fields or inserting code or anything like that.

Only problem... WP will only auto-create the audio enclosure in the RSS feed if you have the mp3 linked from the post content. Since I'm using attachments, it won't auto-create the enclosure, thus no RSS feed w/audio! Any ideas?

You could add the audio enclosure into an excerpt, and only display excerpts in your RSS feed.

Right, but wouldn't that still be creating an extra step for the client? They'd have to copy/paste into the excerpt.

How about auto-creating the excerpt on publishing a post. That way you can automatically add the audio enclosure to the end of each excerpt without your client needing to do anything. They wouldn't even need to know there was an excerpt being used if you hid the excerpt panel from their view.

That's a good idea. I could also auto-create a custom field for the enclosure. Only prob is the client already created 30+ posts, so I'd have to go back and manually add it to those.

Here's what I ended up doing, though I'm open to a more elegant solution! Opened /wp-includes/feed-rss2.php. Replaced the enclosure tag with:

<?php $mp3s = get_children('numberposts=-1&post_type=attachment&post_mime_type=audio&post_parent='.$post->ID); if (!empty($mp3s)) : ?>

<?php foreach($mp3s as $mp3) : ?>

<?php $mp3url = $mp3->guid; $mp3header = get_headers($mp3url, 1); $mp3size = $mp3header['Content-Length']; ?>

<enclosure url="<?php echo $mp3url; ?>" length="<?php echo $mp3size; ?>" type="audio/mpeg" />

<?php endforeach; ?>
<?php endif; ?>

Seems complicated. Just have them add the mp3 file to the post as a link, then use a plugin or something to convert that into the player.

This isn't really an extra step. When you do the upload of the MP3 file to the post, then there's a button that adds it right into the post. All they have to do is click that and a link to the MP3 file gets inserted. Since the link is now in the post, the enclosure works properly. Then you just change the link into a player on display.

Bad idea. You should never modify core files like that. It'll seriously screw with your update path.

My idea above would work, although I'd still be inclined to use Otto's suggestion above even though it doesn't quite meet your specifications since it requires an extra step by the end-user.

Better way to do this exact same thing:

 add_feed('rss2', 'my_custom_feed');

function my_custom_feed( $for_comments ) {
    if ( $for_comments )
        load_template( ABSPATH . WPINC . '/feed-rss2-comments.php' );
    else
        load_template( '/path/to/my/rss2.php' );
} 
  

Then make a copy of the feed-rss2.php file, with your modifications, and have it call that file instead.

^ that's even better :)

Thanks Otto :)
