当我在WP循环中使用下面的代码时，我可以看到播放器和url。不用说，我只想看看球员。

如何更正我的代码，使其只显示播放器？

我的代码如下：

$fes_featured_audio = get_post_meta( get_the_ID(), \'upload_featured_audio\', true ); // custom upload field

if (is_array($fes_featured_audio)) {    
    foreach($fes_featured_audio as $key=>$val){ 

        if ( $key < 1) {
            $url_audio = wp_get_attachment_url( $val ); 
        } else {
            $url_audio_playlist   = explode(\',\', get_attached_media( \'audio\', $val ) ); 
        }

    }
}


$attr = array(
    \'src\'      => strip_tags($url_audio),
    \'loop\'     => \'true\',
    \'autoplay\' => \'\',
    \'preload\'  => \'auto\',
);

if ( $key < 1) {
    echo \'<div class="audio-player" itemprop="audio">\' . wp_audio_shortcode( $attr ) . \' </div>\';
} else {
    echo do_shortcode(\'[playlist ids="\'.$url_audio_playlist.\'"]\');
}
