Enqueuing WordPress playlist scripts with wp_playlist_scripts
The wp_playlist_scripts
function in WordPress is a part of the core WordPress API. This function is primarily responsible for enqueueing the necessary scripts and styles needed to display native WordPress audio and video playlists.
When the wp_playlist_scripts
function is invoked, it enqueues several scripts and styles that are necessary for the correct functioning of the WordPress MediaElement.js library. This library is used by WordPress to handle audio and video playback, and it requires specific scripts and styles to be present on the page to function correctly.
The wp_playlist_scripts
function is typically used when a WordPress theme or plugin needs to display a native WordPress audio or video playlist. By invoking this function, a developer can ensure that all the necessary scripts and styles are properly loaded on the page, thereby ensuring that the playlist will be displayed correctly and function as expected.
It’s important to note that the wp_playlist_scripts
function does not actually output any HTML or generate any playlist markup. Instead, it simply ensures that the necessary scripts and styles are enqueued and ready to be used by the MediaElement.js library.
Parameters Accepted by the wp_playlist_scripts Function
The wp_playlist_scripts
function in WordPress accepts a single parameter. The details of this parameter are as follows:

Return Value of the wp_playlist_scripts Function
The wp_playlist_scripts
function does not return any value. Its purpose is to perform a specific task without providing any output.
Examples
How to Enqueue Playlist Scripts for Audio
The following code snippet demonstrates how to enqueue playlist scripts for audio using the wp_playlist_scripts

function to enqueue playlist scripts for video.
function enqueue_video_playlist() {
wp_playlist_scripts('video');
}
add_action('wp_enqueue_scripts', 'enqueue_video_playlist');
How to Conditionally Enqueue Playlist Scripts
In this final example, we demonstrate how to conditionally enqueue playlist scripts for either audio or video based on a boolean variable $is_audio
.
function enqueue_playlist() {
$is_audio = true; // change this to false for video
if ($is_audio) {
wp_playlist_scripts('audio');
} else {
wp_playlist_scripts('video');
}
}
add_action('wp_enqueue_scripts', 'enqueue_playlist');
In all the examples above, the wp_playlist_scripts
function is used to enqueue the necessary JavaScript and CSS for the mediaelement player used by WordPress for audio or video playlists.

function in WordPress is responsible for enqueuing the necessary scripts and styles for displaying media playlists. It is typically used when a theme or plugin wants to display a playlist of audio or video files, and it ensures that the correct JavaScript and CSS files are loaded to handle the playlist functionality.
