更改下一个/上一个链接以显示帖子标题

Question

所以我目前正在我的个人网站上工作，并开始使用时间线。帖子中有下一个/上一个按钮，但我希望它们显示帖子标题而不是下一个/上一个。我已经查看了wordpress代码，但是开发人员正在使用非标准代码来实现它。

有人可以看看代码并告诉我我需要更改什么。

谢谢！

您可以使用WordPress默认函数来获取下一个和上一个带有永久链接的帖子标题，如下所示：

    <?php  // FOR PREVIOUS POST
        $prev_post = get_previous_post(); 
        $id = $prev_post->ID ;
        $permalink = get_permalink( $id );
    ?>
    <?php // FOR NEXT POST
        $next_post = get_next_post();
        $nid = $next_post->ID ;
        $permalink = get_permalink($nid);
    ?>

然后只需在 HTML 结构中使用此变量，如下所示：

<div class="next-timeline">
     <?php next_post_link( '%link', __( 'Next <span class="meta-nav">&rarr;</span>', 'twentyeleven' ) ); ?>
     <h2><a href="<?php echo $permalink; ?>"><?php echo $next_post->post_title; ?></a></h2>
</div>
<div class="previous-timeline">
     <?php previous_post_link( '%link', __( '<span class="meta-nav">&larr;</span> Previous', 'twentyeleven' ) ); ?> 
     <h2><a href="<?php echo $permalink; ?>"><?php echo $prev_post->post_title; ?></a></h2>                           
</div>

希望这对你有用。

谢谢。

只需删除括号内的代码

<div class="timeline-navigation defa">
                        <div class="next-timeline">
                            <?php next_post_link(); ?>
                        </div>
                        <div class="previous-timeline">
                            <?php previous_post_link(); ?>
                        </div>
</div>

下面是示例：https://wordpress.stackexchange.com/questions/77166/switch-form-next-previous-to-post-title

<nav id="nav-single">
    <h3 class="assistive-text"><?php _e( 'Post navigation', 'admired' ); ?></h3>
    <span class="nav-previous"><?php previous_post_link(); ?></span>
    <span class="nav-next"><?php next_post_link(); ?></span>
</nav><!-- #nav-single -->

打开你的单曲.php比如 ENIF 和 end 之间的二十个十五主题，同时编写下面的代码

// Previous/next post navigation.
            the_post_navigation( array(
                'next_text' => '<span class="meta-nav" aria-hidden="true">' . __( '', 'twentyfifteen' ) . '</span> ' .
                    '<span class="screen-reader-text">' . __( 'Next post:', 'twentyfifteen' ) . '</span> ' .
                    '<span class="post-title">%title</span>',
                'prev_text' => '<span class="meta-nav" aria-hidden="true">' . __( '', 'twentyfifteen' ) . '</span> ' .
                    '<span class="screen-reader-text">' . __( 'Previous post:', 'twentyfifteen' ) . '</span> ' .
                    '<span class="post-title">%title</span>',
            ) );
        // End the loop.
