php - 自定义帖子类型 'single-custom.php' 下一个和上一个链接卡在循环中

Question

我在 Wordpress 中有一个名为“案例”的自定义帖子类型。对于单个页面，我创建了一个 single-case.php，它可以正常工作，但有一点:

在 While 循环之外，我正在尝试使用“下一个”和“上一个”链接，如下所示:

<?php next_post_link('%link', 'next item &gt;') ?>
<?php previous_post_link('%link', '&lt; previous item') ?>

但是他们陷入了一个循环。一旦它到达某篇文章，Wordpress 就会卡住并一遍又一遍地循环相同的两篇文章。

这是完整的(精简的)模板:

... Header ...
<?php while (have_posts()) : the_post(); ?>
    <div class="row content">
        <div class="span4">
        <?php if(count($aImages)) : ?>
            <?php foreach($aImages as $aImage) : ?>
                ....
            <?php endforeach; ?>
        <?php endif; ?>
        </div>

        <div class="span7">
            <div class="case-title"><?php the_title();?></div>
            <?php the_content(); ?>
        </div>
    </div>
<?php endwhile; ?>
... Footer ...

<div class="next-posts pull-right"><?php next_post_link('%link', 'volgend item &gt;') ?></div>
<div class="prev-posts pull-left"><?php previous_post_link('%link', '&lt; vorig item') ?></div>

更新

出于某种原因，这解决了我的问题:

<div class="prev-posts pull-left">
    <?php
    $prev_post = get_previous_post();
    if($prev_post) {
       $prev_title = strip_tags(str_replace('"', '', $prev_post->post_title));
       echo "\t" . '<a rel="prev" href="' . get_permalink($prev_post->ID) . '" title="' . $prev_title. '" class=" "><strong><<< &quot;'. $prev_title . '&quot;</strong></a>' . "\n";
                    }
    ?>
    </div>

    <div class="next-posts pull-right">
    <?
    $next_post = get_next_post();
    if($next_post) {
       $next_title = strip_tags(str_replace('"', '', $next_post->post_title));
       echo "\t" . '<a rel="next" href="' . get_permalink($next_post->ID) . '" title="' . $next_title. '" class=" "><strong>&quot;'. $next_title . '&quot; >>></strong></a>' . "\n";
                    }
    ?>
    </div>

<div class="prev-posts pull-left">
<?php
$prev_post = get_previous_post();
if($prev_post) {
   $prev_title = strip_tags(str_replace('"', '', $prev_post->post_title));
   echo "\t" . '<a rel="prev" href="' . get_permalink($prev_post->ID) . '" title="' . $prev_title. '" class=" "><strong><<< &quot;'. $prev_title . '&quot;</strong></a>' . "\n";
                }
?>
</div>

<div class="next-posts pull-right">
<?php
$next_post = get_next_post();
if($next_post) {
   $next_title = strip_tags(str_replace('"', '', $next_post->post_title));
   echo "\t" . '<a rel="next" href="' . get_permalink($next_post->ID) . '" title="' . $next_title. '" class=" "><strong>&quot;'. $next_title . '&quot; >>></strong></a>' . "\n";
                }
?>
</div>
