为什么此快捷代码函数以错误的顺序返回数据？

Question

我一直在尝试创建一个插件，该插件需要一些ACF选项页面字段，并创建一个快捷代码，该快速代码输出附加到短代码中属性的广告代码，

例如。 [awin id =“ top_banner”]理想情况下将返回该ID输入的代码，

而[awin id =“ midder_banner”]或[awin id =“ bottom_banner”]将分别返回每个横幅的代码页面。

我还添加了通过ACF布尔拨动开关显示和隐藏广告的功能。

我遇到的问题是，如果隐藏广告或短代码不在页面中，它将输出此ID的返回，但是在短码的下一个实例中（不论ID）

示例示例< /strong>

说“ midder_banner”是隐藏的（或者在页面上没有出现的短代码）时，当您向下滚动到bottom_banner的输出时，您会看到“ middle_banner”的输出。当您实际期望看到bottom_banner的输出时。

更新：奇怪的是，ID始终是正确的（我将其作为返回范围内的DIV输出），这始终显示从短代码中显示正确的ID。因此，问题是返回的广告代码。

下面是 问题是否有助于上下文。

// THIS LOOPS THROUGH ADS AND CREATES SHORTCODE ID's within attributes / and assigned ad code to return

           // WP Shortcode to display text on page or post.

            if( have_rows('awin_ads', 'option') ):
               
               while( have_rows('awin_ads', 'option') ): the_row(); 
                   $embed_code = get_sub_field('awin_ad_embed_code');
                   $short_code = get_sub_field('shortcode');
                  // $short_code = preg_replace('/\s+/', '_', $short_code);  /replaces spaces with underscores from input

                   $atts = shortcode_atts( array(
                       'id' => $short_code,
                       'embedded_code' => $embed_code,
                   ), $atts, $tag );

                   extract($atts);

                   $output = '';

                   if($is_live == true) {

                    $output .= '<div id="' . $id . '" style="color:#a0a0a0; text-align:center;"> <hr><p style="margin:0;">Advert</p><br>' . $embedded_code . '<hr></div>'; 

                  }
                  
                  return $output;
               

               endwhile;
              

            endif;
         }
      

      // this makes it init the function after wp has fully loaded
      
      function shortcodes_init(){
       add_shortcode( 'awin', 'awin_func' );
      }

      add_action('init', 'shortcodes_init');

但是，有趣的是，当您检查前端的代码时，ID属性始终将通过正确地传递到输出内的DIV ID。这就是真正使我感到困惑的原因！

在ACF Pro支持下向Alvin大喊，花时间查看此问题并提供解决方案：

“当未通过 https://codex.wordpress.org/shortcode_api。”

他还以一些逻辑写作，根据输出的一些逻辑， ID，然后在发现数据后添加休息时间以停止代码。
