How to use media_library_show_audio_playlist filter in WordPress

media_library_show_audio_playlist filter

By default, the “Create Audio Playlist” button will always be shown in the media library. If this filter returns null, a query will be run to determine whether the media library contains any audio items. This was the default behavior prior to version 4.8.0, but this query is expensive for large media libraries.

To use media_library_show_audio_playlist filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at Flipper Code, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function modify_media_library_show_audio_playlist_defaults which takes 1 parameters and we registered using add_filter. The first parameter media_library_show_audio_playlist is name of the hook, The second parameter modify_media_library_show_audio_playlist_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_filter to remove media_library_show_audio_playlist filter.

Parameters

Below the 1 parameter is required to use this hook.

• $show : (bool|null) Whether to show the button, or null to decide based on whether any audio files exist in the media library.

Live Example

apply_filters( 'media_library_show_audio_playlist', bool|null $show )

Below is an example how you can use this hook.

                        function modify_media_library_show_audio_playlist_defaults($show) { 
   
                            // Update the $show variable according to your website requirements and return this variable. You can modify the $show variable conditionally too if you want.

                            return $show; 
                        }
                        // add the filter
                        add_filter( "media_library_show_audio_playlist", "modify_media_library_show_audio_playlist_defaults", 10, 1 );

To remove a hook callback, use the example below.

remove_filter( "media_library_show_audio_playlist", "modify_media_library_show_audio_playlist_defaults", 10, 1 );

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