Get_the_Category和Echo Out链接至子最深/最深类别

我在搜索中找到了这个代码。php页面并检索每篇文章的所有类别，echo将链接到第一个类别：

$category = get_the_category(); //print_r($category);
if ($category) {
  echo \'<a href="\' . get_category_link( $category[0]->term_id ) . \'" title="\' . sprintf( __( "View all posts in %s" ), $category[0]->name ) . \'" \' . \'>\' . $category[0]->name.\'</a> \';

我需要做的是使用类似的代码，但这会得到数组中最深/最深的子类别？

这是打印出来的阵列：

[0] => stdClass Object
    (
        [term_id] => 170
        [name] => ACS Series Suspended &amp; Crane Scales - EC Approved
        [slug] => uwe-acs-series-suspended-crane-scales
        [term_group] => 0
        [term_taxonomy_id] => 170
        [taxonomy] => category
        [description] => 
        [parent] => 3
        [count] => 4
        [object_id] => 1578
        [cat_ID] => 170
        [category_count] => 4
        [category_description] => 
        [cat_name] => ACS Series Suspended &amp; Crane Scales - EC Approved
        [category_nicename] => uwe-acs-series-suspended-crane-scales
        [category_parent] => 3
    )

[1] => stdClass Object
    (
        [term_id] => 3
        [name] => Crane Scales
        [slug] => crane-scales
        [term_group] => 0
        [term_taxonomy_id] => 3
        [taxonomy] => category
        [description] => 
        [parent] => 0
        [count] => 53
        [object_id] => 1578
        [cat_ID] => 3
        [category_count] => 53
        [category_description] => 
        [cat_name] => Crane Scales
        [category_nicename] => crane-scales
        [category_parent] => 0
    )

如您所见，一个类别的父级->3，另一个类别的父级->0。如何使用上述查询仅打印父级为->3的类别的链接？

这可能很简单，但有点让我不知所措。任何帮助都将不胜感激！

谢谢

function get_deep_child_category( $categories ) { $maxId = 0; $maxKey = 0; foreach ( $categories as $key => $value ) { if ( $value->parent > $maxId ) { $maxId = $value->term_id; $maxKey = $key; } } return $categories[$maxKey]; }

$categories = get_the_category(); if ( $categories ) : $deepChild = get_deep_child_category( $categories ); ?> <a href="<?php echo get_category_link( $deepChild->term_id ); ?>" title="<?php echo sprintf( __( "View all posts in %s" ), $deepChild->name ); ?>"><?php echo $deepChild->name; ?></a> <?php endif;
