我需要分页方面的帮助。我试图将下一页和上一页显示该帖子的内容放在同一个类别中，但我不确定会发生什么，即什么都没有显示。

如果你能帮忙，非常感谢！

    <div class="row">
    <div class="page">
    <?php 
    $previous_post = get_previous_post(\'%link\', \'Next post in category\', TRUE);
    if ( $previous_post ) : ?>

    <!-- [ PREVIOUS ITEM ]-->
    <div class="col-xs-6">
    <?php if ( has_post_thumbnail( $previous_post->ID ) ) : ?>
    <?php echo get_the_post_thumbnail( $previous_post->ID, \'gallery-navigation\' ); ?>
    <?php endif; ?>
    <a href="<?php echo get_permalink( $previous_post->ID ); ?>"><div class="info">
    <div class="info-gallery">
    <h2 class="title"><?php echo $previous_post->post_title; ?></h2>
    </div><!-- .info-content -->
    </div></a><!---info -->

    <span class="prevnext"><?php _e( \'Previous Featured\', ); ?></span></div>
    <?php endif; //End of Previous Post Item ?>

    <?php $next_post = get_next_post(\'%link\', \'Next post in category\', TRUE);
    if ( $next_post ) : ?>

    <!-- [ NEXT ITEM ]-->
    <div class="col-xs-6">
    <?php if ( has_post_thumbnail( $next_post->ID ) ) { 
    echo get_the_post_thumbnail( $next_post->ID, \'gallery-navigation\' ); }?>
    <a href="<?php echo get_permalink( $next_post->ID ); ?>"><div class="info">
    <div class="info-gallery">
    <h2 class="title"><?php echo $next_post->post_title; ?></h2>
    </div><!-- .info-content -->
    </div></a><!-- -info -->

    <span class="prevnext"><?php _e( \'Next Featured\'); ?></span></div>
    <?php endif; //End of Next Post Item ?>
