对于我的相关帖子，我设置了一个可滚动的容器。我需要HTML在循环之外，否则如果没有相关的帖子显示，布局会很混乱（只有在有相关帖子显示的情况下，循环内才会缺少div）。

因此，我唯一的选择是在容器中显示一条消息，该消息仅在没有相关帖子显示时显示。类似于：“抱歉，此条目没有相关帖子”

不幸的是，我不知道如何修改代码/如何将其实现到当前代码中：

<h2>Related Posts</h2>                      

<!-- "previous page" action -->
<a class="prev browse left"></a>


<!-- root element for scrollable -->
<div class="scrollable" id=chained>  

    <!-- root element for the items -->
    <div class="items">

<?php

 $tags = wp_get_post_tags($post->ID);
 if ($tags) {
     $tag_ids = array();
     foreach($tags as $individual_tag) $tag_ids[] = $individual_tag->term_id;

 $args=array(
\'tag__in\' => $tag_ids,
\'post__not_in\' => array($post->ID),
\'showposts\'=>12, // get all the posts at once, then split them up afterwards.
\'ignore_sticky_posts\' => 1
 );

$posts_per_block = 4;

$my_query = new wp_query($args); ?>



<?php
if( $my_query->have_posts() ) : while ($my_query->have_posts()) : $my_query->the_post();
if ( ($my_query->current_post) == 0 ) {
    echo \'<div>\';
}
elseif ( ( $my_query->current_post ) % $posts_per_block == 0 ) {
    echo \'</div><div>\'; //close and open a new div every nth post
}
?>

<div class="relatedPosts"><a href="<?php the_permalink() ?>" rel="bookmark"><?php the_post_thumbnail(array(120,80)); ?></a>
<div class="relatedPosts_title"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></div></div>

<?php

if ( ( $my_query->current_post + 1) == ( $my_query->post_count ) ) {
    echo \'</div>\'; //close the block if you run out of posts
} ?>

<?php
endwhile; endif;
?>



<?php } // end if($tags) ?>
  </div>

 </div>

<!-- "next page" action -->
<a class="next browse right"></a>

Here\'s 标签和相关帖子的示例。

提前非常感谢任何能帮我解决这个问题的人。
