media_library_show_audio_playlist filter-hook . WP 4.7.4

Allows showing or hiding the "Create Audio Playlist" button in the media library.

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.

Usage

add_filter( 'media_library_show_audio_playlist', 'filter_function_name_7561' );
function filter_function_name_7561( $true ){
	// filter...

	return $true;
}
$true(true/false/null)
Whether to show the button, or null to decide based on whether any audio files exist in the media library.

Notes

  • Since 4.8.0 The filter's default value is true rather than null.
