结果证明我根本没有做循环的循环。这是几年前的事了。我甚至不知道我是怎么想到这一点的，因为条款/限制和DB之类的东西仍然让我有点不知所措。不管怎样，我希望它能帮助一些人。。。我确信我有一个循环的循环，但这也不难写。

//remove limits from article CPT archive
function kia_archive_limits( $limits ) {

  if( ! is_admin() && ( is_post_type_archive( \'article\' ) ) ) {
     // remove limits
     $limits = \'\';
  }

  return $limits;
}
add_filter(\'post_limits\', \'kia_archive_limits\' );


//complicated queries for articles depending on query var
function kia_article_clauses( $clauses, $wp_query ) {
    global $wpdb;

    if( is_post_type_archive( \'article\' ))  {

        //join term_relationships to posts, and term_relationships to term_taxonomy and term_taxonomy to terms
        $clauses[\'join\'] .= "LEFT OUTER JOIN {$wpdb->term_relationships} ON {$wpdb->posts}.ID={$wpdb->term_relationships}.object_id
LEFT OUTER JOIN {$wpdb->term_taxonomy} USING (term_taxonomy_id)
LEFT OUTER JOIN {$wpdb->terms} USING (term_id)" ;

        //group posts by term name
        $clauses[\'groupby\'] = "object_id";

        //include posts with and without a subject term
        $clauses[\'where\'] .= " AND (taxonomy = \'subject\' OR taxonomy IS NULL)";
        $clauses[\'orderby\']  = "GROUP_CONCAT({$wpdb->terms}.name ORDER BY name ASC) ";

    } 

    return $clauses;
}
add_filter( \'posts_clauses\', \'kia_article_clauses\', 10, 2 );

我的循环代码如下所示：

<div class="column">

<?php

$prev = \'\'; $counter = 1; $column = 1;

while ( have_posts() ) : the_post();  

    $subhead =  array_shift(wp_get_post_terms(get_the_ID(), \'subject\', array("fields" => "names")));
    $subhead = $subhead ? $subhead : __(\'No Subject\',\'peterwade\');

    if($counter >= 20) { 
        //reset the counter
        $counter = 1;

        $column++;

        //what column are we on?
        if($column == 5 ){
            $column = 1; //reset column count
            $hr = \'<hr class="clear"/>\';
        } else { 
            $hr = false; 
        }

        if ($column == 4) { 
            $class = "column last";
        } else {
            $class = "column";
        }

     ?>
    </div><!--.column-->

    <?php if($hr) echo $hr;?>

    <div class="<?php echo $class;?>">

    <h3 class="subhead"><?php printf(\'%s <span class="continued">%s</span>\', $subhead, __(\'continued\'));?></h3>
    <?php 
        }


    if($subhead != $prev) { 
        $counter++; ?>
        <h3 class="subhead"><?php echo $subhead;?></h3>
        <ul>
    <?php } ?>

        <li><a href="<?php echo get_permalink();?>" title="<?php echo __(\'Permalink to\') . \' \' . get_the_title();?>"><?php the_title();?></a></li>
    <?php 

    if($subhead != $prev) { ?>
        </ul>
    <?php }

    $prev = $subhead;
    $counter++;

endwhile; ?>

</div><!--.column-->

现在看看我链接到你的页面上的来源，他似乎又回到了以前的做事方式。。。。又称作一张巨大的桌子。我不能说这是不是因为我的代码停止工作了。

Alternative

这将是一个循环的循环。循环浏览术语，然后查询每个术语中的帖子。您必须进行基准测试，以确定哪种方法更快。我强烈建议将查询存储在某种瞬态中，但现在是吃饭的时候了！

$terms = get_terms( \'genre\' );

if( $terms ):

foreach( $terms as $term ){

    // The Query
    $args = array(
      \'post_type\' => \'book\',
      \'nopaging\' => true,
      \'tax_query\' => array(
         array( 
            \'taxonomy\' => \'genre\',
            \'field\' => \'id\',
            \'terms\' => $term->term_id 
         )
      )    
);

    $the_query = new WP_Query( $args );

    // The Loop
    if ( $the_query->have_posts() ) {
        echo \'<h2>\' . ucwords( $term->name ) . \'</h2>\';
            echo \'<ul>\';
        while ( $the_query->have_posts() ) {
            $the_query->the_post();
            echo \'<li>\' . get_the_title() . \'</li>\';
        }
        echo \'</ul>\';
    } 
}

endif;
