I created a custom meta box called Podcasts where a user can upload a podcast. This custom meta box is only available on a custom post type called Podcasts. I am now trying to figure out how to connect to iTunes. I need to make sure that the audio appears in the RSS feed for the custom post type.
I put the following in my functions.php:
//Add Audio to Podcast Feed
function add_audio_to_feed($content) {
if(is_feed()) {
$post_id = get_the_ID();
$output .= '<audio controls> <source src="' . get_post_meta($post_id, 'podcast', true) . '" type="audio/mpeg"></audio>';
$content = $content.$output;
}
return $content;
}
add_filter('the_content','add_audio_to_feed');
This outputs this to the XML:
<audio controls> <source src="" type="audio/mpeg"></audio>
Why is the source blank? In the archive template for my custom post type, the following code works just fine…
<audio controls>
<source src="<?php the_field('podcast'); ?>" type="audio/mpeg">
Your browser does not support the audio element.
</audio>
Any help would be much appreciated.
I’ve also tried this:
//Add Audio to Podcast Feed
function add_audio_to_feed($content) {
if(is_feed()) {
$post_id = get_the_ID();
$output .= '<audio controls> <source src="' . the_field('podcast') . '" type="audio/mpeg"></audio>';
$content = $content.$output;
}
return $content;
}
add_filter('the_content','add_audio_to_feed');
Hi!
Did you find a solution to the problem?
