通常，答案取决于您的

$permalinks = get_option( \'permalink_structure\' )

如果没有返回false, 然后启用了永久链接。然后，您可以检查您的设置并从中构建精确的链接。

然后，您可以简单地提取所需的列表/对象部分并构建链接。

// Maybe you want them for the labels?
$cat_names = wp_list_pluck( get_the_category( get_the_ID() ), \'name\' );

// For nice permalinks
$cat_slugs = wp_list_pluck( get_the_category( get_the_ID() ), \'slug\' );
// For non-beautiful permalink sites
$cat_IDs   = wp_list_pluck( get_the_category( get_the_ID() ), \'term_id\' );

由于我不知道您将如何对它们进行排序/排序，也不知道您的具体目标是什么，因此我无法为您提供解决方案，只需确定下一个/上一个类别，然后建立链接：

printf( 
     \'<a href="%1$s" title="%2$s">%2$s</a>\'
    ,home_url( \'/\' ) // Append your link inside the single quotes after the slash
    ,$cat_name[0]    // Set your next/prev cat here
);

此函数适用于类别（无层次结构）和标记。它还达到了第一个分类法（cat或tag）。您可以将其添加到函数中。php

<?php
if (!function_exists(\'my_tax_paging_nav\')) {
/*
Display navigation to next/previous set of categories/tags when applicable.
*/
function my_tax_paging_nav()
{
    $this_taxonomy = get_queried_object();
    if (is_category()) {
        $taxonomies = get_categories();
        //for other languages than english
        $plural     = \'\';
        $taxlabel   = \'Category\';
    }
    if (is_tag()) {
        $taxonomies = get_tags();
        //for other languages than english
        $plural     = \'s\';
        $taxlabel   = \'Tag\';
    }

    foreach ($taxonomies as $position => $tax):
        if ($this_taxonomy->term_id == $tax->term_id):
            $next_tax = $position + 1;
            $prev_tax = $position - 1;
            break;
        endif;
    endforeach;

    //variables to show/hide when top/bottom is reached
    $showPrev;
    $showNext;
    //bottom
    if ($prev_tax < 0){
        $prev_tax=count($taxonomies) - 1;
        $showPrev=\'\';
        }else{
            $prev_tax;
            $showPrev = \'<span class="meta-nav">&larr; </span><small>Vorherige\' . $grammatik . \' \' . $taxlabel . \': </small>\' . $taxonomies[$prev_tax]->name;
        }

    //top
    if ($prev_tax == count($taxonomies)-2){
        $next_tax=0;
        $showNext = \'\';
        }else{
            $showNext = \'<small>Nächste\' . $grammatik . \' \' . $taxlabel . \': </small>\' . $taxonomies[$next_tax]->name.\'<span class="meta-nav"> &rarr;</span>\';
            }

    $prevLink = get_term_link( $taxonomies[$prev_tax] );
    $nextLink = get_term_link( $taxonomies[$next_tax] );
    ?>
    <nav class="navigation post-navigation" role="navigation">
        <div class="nav-links">
            <div class="nav-previous"><a href="<?php echo $prevLink;?>"><?php echo $showPrev; ?></a></div>
            <div class="nav-next"><a href="<?php echo $nextLink;?>"><?php echo $showNext ?></a></div>
        </div><!-- .nav-links -->
    </nav><!-- .navigation -->
    <?php
  }
}//end if     

您可以在类别中调用此函数。php或标记。php：

<?php my_tax_paging_nav(); ?>

您可能需要根据需要更改html标记。我希望这能帮助别人。问候西奥
