F4 Media Taxonomies

常見問題

How to enable categories

The built-in taxonomy category can be enabled with this snippet. Just put it into your functions.php:

add_action('init', function() {
    register_taxonomy_for_object_type('category', 'attachment');
});

How to enable tags

The built-in taxonomy post_tag can be enabled with this snippet. Just put it into your functions.php:

add_action('init', function() {
    register_taxonomy_for_object_type('post_tag', 'attachment');
});

How to enable custom taxonomies

There are two ways to enable custom taxonomies for attachments:

New taxonomy:

If the taxonomy does not exist yet and you want to create a new one, you have to set the object_type in the register_taxonomy() function to attachment (see WordPress codex).

add_action('init', function() {
    register_taxonomy(
        'media-category',
        'attachment'
    );
});

Existing taxonomy:

If the taxonomy is already registered, you can assign it with this snippet. Just put it into your functions.php and change media-category to your taxonomy:

add_action('init', function() {
    register_taxonomy_for_object_type('media-category', 'attachment');
});

The filters do not appear in the media overlay

For a better performance, we only include the scripts and files when they are needed. Some plugins can cause a problem with this functionality.
For this case we offer a hook, which allows you to enable the filter for special conditions. If this hook returns true, the filter is enabled for the current site.

add_filter('F4/MT/Core/has_filter', function() {
    return true;
});

Can I enable taxonomies directly in the backend?

No. We simply use the taxonomies that are registered in the code. Maybe in the future, but we want to keep this plugin as lightweight and simple as possible.

Is it really free?

Yes, absolutely!
