Question

我是php的新手，所以我想得到一些帮助。

我的客户希望下一个和上一个按钮在单页组合中循环。这是我正在使用的代码。

<?php
$prev_post = get_previous_post();
$next_post = get_next_post();
$prev_post_link = !empty($prev_post) ? get_permalink($prev_post->ID) : true;
$next_post_link = !empty($next_post) ? get_permalink($next_post->ID) : true;
if(!empty($prev_post) && empty($prev_post_thumb)) $prev_post_thumb = prev_next_post_format_icon($prev_post->ID);
if(!empty($next_post) && empty($next_post_thumb)) $next_post_thumb = prev_next_post_format_icon($next_post->ID);
?>

当我使用True时，对于Previous和amp; Next Links，它出现在第一个和最后一个投资组合中，但超链接显示为http://1而不是下一个投资组合。在此先感谢

这是我的HTML代码：

<div class="dfd-controls mobile-hide">
<?php if(!empty($prev_post_link)) : ?>
    <a href="<?php echo esc_url($prev_post_link); ?>" class="page-inner-nav nav-prev">
        <div class="dfd-controler prev">
        <div style="margin-top:7px; color:#fff;">Previous</div>
            <!-- <div class="thumb prev"> 
                <?php echo $prev_post_thumb; ?>
            </div> -->
        </div>
        <!--<div class="pagination-title">Previous Project</div> -->
    </a>
<?php endif; ?>
<?php if(!empty($next_post_link)) : ?>
    <a href="<?php echo esc_url($next_post_link); ?>" class="page-inner-nav nav-next">
        <div class="dfd-controler next">
            <div style="margin-top:7px; color:#fff;">Next</div>
            <!-- <div class="thumb next">
                <?php echo $next_post_thumb; ?>
            </div>-->
        </div>
        <!--<div class="pagination-title">Next Project</div>-->
    </a>
<?php endif; ?>

将值从true更改为false。将变量设置为true会使empty为假值see here。

现在＆＃39; next＆＃39;只会显示是否有下一篇文章

你的PHP应该是：

$prev_post = get_previous_post();
$next_post = get_next_post();
$prev_post_link = !empty($prev_post) ? get_permalink($prev_post->ID) : false;
$next_post_link = !empty($next_post) ? get_permalink($next_post->ID) : false;
if(!empty($prev_post) && empty($prev_post_thumb)) $prev_post_thumb = prev_next_post_format_icon($prev_post->ID);
if(!empty($next_post) && empty($next_post_thumb)) $next_post_thumb = prev_next_post_format_icon($next_post->ID);

更新：要发布帖子：

if( get_adjacent_post(false, '', true) ) { 
    previous_post_link('%link', '<div class="dfd-controler prev"><div style="margin-top:7px; color:#fff;">Previous</div></div>');
} else { 
    $first = new WP_Query('posts_per_page=1&order=DESC'); $first->the_post();
        echo '<a href="' . get_permalink() . '"><div class="dfd-controler prev"><div style="margin-top:7px; color:#fff;">Previous</div></div></a>';
    wp_reset_query();
}; 

if( get_adjacent_post(false, '', false) ) { 
    next_post_link('%link', '<div class="dfd-controler next"><div style="margin-top:7px; color:#fff;">Next</div></div>');
} else { 
    $last = new WP_Query('posts_per_page=1&order=ASC'); $last->the_post();
        echo '<a href="' . get_permalink() . '"><div class="dfd-controler next"><div style="margin-top:7px; color:#fff;">Next</div></div>';
    wp_reset_query();
};

循环投资组合Wordpress中的下一个/上一个按钮

     <div class='next_post_link_align'>
<?php next_post_link('<span class="previous_post_link">&larr; %link </span> <span class="post_link_text">'.__('(previous entry)','avia_framework'))."</span>";?>
</div>   
    <div class='previous_post_link_align'>
<?php previous_post_link('<span class="next_post_link"><span class="post_link_text">'.__('(next entry)','avia_framework').'</span> %link &rarr;</span>'); ?>
</div>
