自定义快捷码+使用多个高级自定义复选框查询和订购帖子

我正在处理函数内部的自定义短代码函数。php将显示“speakers”帖子类型，带有“featured speaker”ACF复选框，并按ACF select元素设置的特定顺序显示。Bt自定义短代码不显示任何内容。我已经检查了很多次代码，但我无法发现我做错了什么。

add_shortcode( \'featured_speakers_clzd\', \'custom_speakers_clzd\' );function custom_speakers_clzd() {

$args = array(
    \'post_type\' => \'speaker\',
    \'posts_per_page\' => -1,
    \'post_status\' => \'publish\',
      \'meta_query\' => array(
                \'relation\' => \'AND\',
                array(
                    \'key\'       => \'featured_speaker\',
                    \'value\'     => \'1\',
                    \'compare\'   => \'=\',
                ),
                array(
                    \'key\' => \'speaker_order\',
                    \'orderby\' => \'meta_value\',
                    \'order\' => DESC,
                ),

            ),
    );

$query = new WP_Query( $args );

$out = \'\';

$out .= \'<div class="full_section_inner">\';

if ( $query->have_posts() ) {
    // The Loop
    while ( $query->have_posts() ) {
          $query->the_post();
          $out .= \'<div class="vc_col-sm-3">\';

                          $out .= get_the_post_thumbnail( get_the_ID(), \'thumbnail\' );

return $out;

Namespaced shortcode?

我正在改造一个旧的WP站点，该站点有许多自定义的短代码，显然由于代码当前的组织方式，这些短代码在性能方面付出了代价。当然，我可以修复优化不好的代码，使用十几个短代码，并且一天就可以完成，但我想知道如何更好地组织它们。根据WordPress\'documentation, 建议将它们放在插件中并在上初始化init. 我们可以通过这样“命名”它们来减少这个钩子中的负载吗？[com.company shortcode attr=\"attr\" prop=\"prop\"] 有人尝试过这样的解决方案吗
