如何在子类别归档页面上回显自定义分类法类别的父名称和永久链接

我为自定义帖子类型(case_studies)提供了自定义分类(expertise_taxonomy),并为其提供了归档模板(taxonomy-expertise.php)。我的问题是,在子类别页面上,我需要在页面顶部回显其父类别名称及其永久链接(想想breadcrumb)。我能够获得父类别ID,但无法获得永久链接的名称。看起来get_ancestors是正确的方向,但我得到的只是一个空数组。

以下是我的模板代码的相关部分:

    <?php

     $taxonomy = get_query_var('taxonomy');
     $termId = get_queried_object()->term_id;
     $title = get_field('expertise_deliverables_title', $taxonomy . '_' . $termId);
     $content = get_field('expertise_deliverables', $taxonomy . '_' . $termId);
     $parent = get_queried_object()->parent; 
     ?>

    <?php if ( have_posts() ) : ?>

    <p><a href="/expertise">Expertise</a> |

     <!-- This is where the parent permalink should go -->
     <a href="/">

     <!-- This is where the parent ID is echoed instead of the name -->
     <?php echo $parent; ?>

     </a> | <?php echo str_replace('Expertise: ','', get_the_archive_title()); ?></p>

示例所需的输出是在查看“Apple”子类别存档页面时,它会在面包屑中具有其父类别“Fruit”,如下所示:

Expertise | <a href="/fruit">Fruit</a> | Apple

真的很感激任何帮助!

您正在寻找的功能是get_term_link。它需要术语对象,ID或slug和分类名称,并返回术语登录页面的URL。

Wordpress Codex查看有关此功能的更多信息:     

 $taxonomy = get_query_var('taxonomy');
 $termId = get_queried_object()->term_id;
 $title = get_field('expertise_deliverables_title', $taxonomy . '_' . $termId);
 $content = get_field('expertise_deliverables', $taxonomy . '_' . $termId);
 $parent = get_queried_object()->parent; 
 ?>
<?php $term_link = get_term_link( $parent, $taxonomy );?>

<?php if ( have_posts() ) : ?>

<p><a href="/expertise">Expertise</a> |

 <!-- This is where the parent permalink should go -->
 <a href="<?php echo $term_link; ?>">

 <!-- This is where the parent ID is echoed instead of the name -->
 <?php echo $parent; ?>

 </a> | <?php echo str_replace('Expertise: ','', get_the_archive_title()); ?></p>

Deepti让我开始了,这是我如何做到的:

$parent = get_queried_object()->parent; // gets parent category ID
$taxonomy = get_query_var('taxonomy'); // gets the taxonomy name
$term_link = get_term_link( $parent, $taxonomy ) // Deepti's answer to get parent category link
$r = $term_link; // declares new variable with parent category link
$r = explode('/', $r); // separates url parts based on '/' delimiter
$r = array_filter($r); // creates array of parts
$r = array_merge($r, array()); // resets array keys
$code = $r[3]; // variable containing the third array key - works for my purposes because I will always need the third part (last part) of my url   
$string = str_replace("-", " ", $code); // removes the dash if dash exists in my slug and replaces it with a space

<?php echo $string; ?>

这为我的面包屑提供了父类别名称(Fruit): 专业知识|水果|苹果
