通过自定义字段（ACF）/ Wordpress筛选

Question

我有一个循环，我有一些标准的排序选项，包括排序日期&标题。我也有第三个选项，我想添加哪些过滤器“Studio”质量帖子...我添加了一个复选框，我可以选择或取消选择在每个帖子的后端，但我如何将它添加到我的过滤器？

我写了这个代码，它允许最终用户帖子排序，但我需要添加一个第三选择

<div class="btn-group btn-group-vi"> 
          <button type="button" class="btn btn-sort dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"><?php if(!empty($orderby == 'title')) { echo "Alphabetical"; } elseif($orderby = 'date') { echo "Date Added"; } else { echo "Order by"; } ?></button> 
          <div class="dropdown-menu"> 
           <a class="dropdown-item" href="?orderby=title<?php if(!empty($order)) { echo "&order=" . $order; } ?>">Alphabetical</a> 
           <a class="dropdown-item" href="?orderby=date<?php if(!empty($order)) { echo "&order=" . $order; } ?>">Date Added</a> 
          </div> 
         </div> 

         <div class="btn-group btn-group-vi"> 
          <button type="button" class="btn btn-sort dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"><?php if(!empty($order == 'asc')) { echo "ASC"; } elseif($order = 'desc') { echo "DESC"; } else { echo "Order"; } ?></button> 
          <div class="dropdown-menu"> 
           <a class="dropdown-item" href="<?php if(!empty($orderby)) { echo "?orderby=" . $orderby . "&"; } ?>order=asc">ASC</a> 
           <a class="dropdown-item" href="<?php if(!empty($orderby)) { echo "?orderby=" . $orderby . "&"; } ?>order=desc">DESC</a> 
          </div> 
         </div> 

         <?php 

          $loop = new WP_Query(array( 
           'post_type' => 'acapella', 
           'posts_per_page' => 18, 
           'paged' => $paged, 
           'orderby' => $orderby, 
           'order' => $order 
          )); 
          $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; 
         ?> 

我还添加在ACF添加新的自定义字段的屏幕截图。

编辑您的ARGS包括元键“studio_acapella”：

$loop = new WP_Query(array( 
    'post_type' => 'acapella', 
    'posts_per_page' => 18, 
    'paged' => $paged, 
    'orderby' => $orderby, 
    'order' => $order, 
    'meta_query' => array(
    array(
     'key'  => 'studio_acapella', 
     'value'  => true 
    ), 
    ) 
) 
));
