How to use feed_content_type filter in WordPress

Alright, let’s dive into the world of WordPress hooks! As an Indian developer, I can tell you that hooks are like the secret sauce that makes WordPress super flexible. Today, we’re looking at the feed_content_type filter, which modifies the content type for a specific feed type. You’ll want to register this filter using add_filter, either in your theme’s functions.php file or a custom WordPress plugin. Personally, I always prefer creating a plugin—it’s safer for updates!

Example 1: Adjusting Content Type for RSS Feeds

This example shows how to modify the content type for RSS feeds. It’s pretty straightforward!

function weplugins_modify_feed_content_type_rss($content_type, $type) {
    if ($type === 'rss') {
        $content_type = 'application/rss+xml';
    }
    return $content_type;
}
add_filter("feed_content_type", "weplugins_modify_feed_content_type_rss", 10, 2);

Example 2: Custom Content Type for Atom Feeds

Here, we customize the content type for Atom feeds. This is useful if you want to specify a different content type for Atom.

function weplugins_modify_feed_content_type_atom($content_type, $type) {
    if ($type === 'atom') {
        $content_type = 'application/atom+xml';
    }
    return $content_type;
}
add_filter("feed_content_type", "weplugins_modify_feed_content_type_atom", 10, 2);

Example 3: Removing the Hook

In some cases, you might want to remove a previously registered hook. Here’s how you can do it.

remove_filter("feed_content_type", "weplugins_modify_feed_content_type_rss", 10, 2);

Just make sure you provide the same callback function name, priority, and number of arguments while removing the hook callback.
