I think I found a reliable way by using gallery field:
$audio_playlist = get_field( ‘audio_playlist’ ); //gallery field
$playlist = array();
foreach ( $audio_playlist as $audio ){
array_push ( $playlist, $audio[“ID”] );
}
echo ‘<div class=”audio-container”‘.do_shortcode(‘[playlist ids="'.implode(',',$playlist).'"]‘).'</div>’;
What do you think?
