它们可能是实现您所需的更省钱的方法，可能是使用jQuery或更严格定制的代码版本，但只要保持WordPress的核心功能，您就可以尝试以下方法，该方法利用wp_audio_shortcode_override 滤器

我使用is_page() 对于主条件。您可以使用以下条件替换页面模板文件名get_page_template_slug() 如图所示：

/**
 * Use audio shortcode override filter selectively 
 * to replace built-in shortcode function with modified version
 * on pages using the specified template
 */

add_filter( \'wp_audio_shortcode_override\', \'add_keep_playing_att_on_these\', 10, 4 );

function add_keep_playing_att_on_these($override, $attr, $content, $instance) {

    if ( \'page-audio.php\' === get_page_template_slug( get_the_ID() ) ) {

        /**
         * EXCEPT AS NOTED
         * FROM HERE UP TO THE RETURN STATEMENTS
         * function mostly re-produces audio shortcode function from media.php
         * I removed the html filter from the original code, but may return later and put it back!
