我为自定义帖子类型创建了一个循环workshop 具有两个自定义分类法group 和teacher 在同一页上由于提供了解决方案，Ajax过滤器可以完美地工作here. 用户可以选择一种或两种分类法来显示帖子。

过滤器的每个链接都与<input type="radio"...>, 对于这两个分类列表。我试图实现的是创建一个按钮.filter-reset 重置所有无线电输入并显示我的自定义帖子类型的所有帖子。

问题是，当我单击按钮时，它返回；找不到帖子；。

以下是前端过滤器的PHP代码：

<form action="<?php echo site_url() ?>/wp-admin/admin-ajax.php" method="POST" id="filter" class="form-filter">
   <div class="container">
   <?php

   if( $terms = get_terms( \'group\', \'orderby=name&exclude=-1\' ) ) :
    echo \'<div class="filter-tax filter--group">\';
    foreach ( $terms as $term ) :
      echo \'<input class="btn-radio" type="radio" name="categoryfilter1" value="\' . $term->term_id . \'"><label>\' . $term->name . \'</label>\';
    endforeach;
    echo \'</div>\';
   endif;

   if( $terms = get_terms( \'teacher\', \'orderby=name&exclude=-1\' ) ) :
     echo \'<div class="filter-tax filter--teacher">\';
     foreach ( $terms as $term ) :
       echo \'<input class="btn-radio" type="radio" name="categoryfilter2" value="\' . $term->term_id . \'"><label>\' . $term->name . \'</label>\';
     endforeach;
     echo \'</div>\';
    endif;

    ?>
