如何根据日期对wordpress中的帖子进行分组和排序？

Question

我有以下代码按标题对帖子进行排序。请参阅随附的屏幕截图。

想要的结果

这就是我现在得到的

我想要的是将帖子组合在一起，即日期为 12 月的帖子应低于 12 月，而 11 月的帖子应低于 11 月，依此类推。附上两张图片。

我需要对下面的代码进行一些调整。

                 <div class="margin-top" style="margin-top: 20px;">
                <?php if ( have_posts() ) : ?>

                        <?php update_post_thumbnail_cache(); ?>

                                <?php while ( have_posts() ) : the_post(); ?>

                                <?php

      global $post;
      $venue_a = get_term_by('slug',$venue, 'venues');
      for($i=0;$i<10;$i++){
        $key = get_post_meta($post->ID,'sub_seminars_'.$i.'_venue',true);

        if($venue_a->name == $key ){
          $ref = get_post_meta($post->ID,'sub_seminars_'.$i.'_ref',true); 
          $ven_label = get_post_meta($post->ID,'sub_seminars_'.$i.'_venue',true);

          $start =1;
          break;

显示的场所是创建的自定义分类法

这是我为解决上述问题而编写的代码

<?php

$archiveId = $archive_data->term_id;
$categroy_name =  $archive_data->slug;
$seminar_venue = $archive_data->name;
$subseminars_found = euromatech_search_subseminars( '', $archive_data->slug, '');
 if(!empty($subseminars_found)){
    foreach($subseminars_found as $month => $day){
        ?>
        <div class="dec-box">
            <h3 class="year-title"><?php echo date('M Y', $month); ?></h3>
            <div class="register-table table-sec">

                    <?php

                    foreach($day as $subseminars){
                        foreach($subseminars as $subseminar) {

                            ?>

                            <tr>
                                <td class="left-td"><a href="<?php the_permalink($subseminar['seminarID']); ?>">

                            </tr>

                            <?php                          
                        }
                    }
                    ?>
                </table>
            </div>
        </div>

        <?php
    }

} 

else {

    echo '<h4>No Upcoming Seminars found</h4>';
    echo '<p>For further information on forthcoming events in this region, please contact <a href="mailto:',ot_get_option('email_address', ''),'">',ot_get_option('email_address', ''),'</a></p>';
}

?>
