| wp-includes/media.php | apply_filters | 4422 | /** * 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. * * @since 4.7.4 * @since 4.8.0 The filter's default value is `true` rather than `null`. * * @link https://core.trac.wordpress.org/ticket/31071 * * @param bool|null $show Whether to show the button, or `null` to decide based * on whether any audio files exist in the media library. */ |
