我正在建立一个非营利家庭暴力支持网站，并努力寻找一种方法，在侧边栏的页面中创建积极类别的家长和it儿童链接。
动态显示类别父级及其子级的理想解决方案是什么？

$current_cat_id = get_queried_object_id();
$kids = get_terms([
\'taxonomy\' => get_queried_object()->taxonomy,
\'parent\' => $current_cat_id,
]);
<?php
$terms = get_terms([
\'taxonomy\' => get_queried_object()->taxonomy,
\'parent\' => get_queried_object_id(),
]);
echo \'<div style="height: 200px; text-transform: uppercase; border:1px solid #666666; padding:10px; overflow-y: scroll;">
<ul>
foreach ( $terms as $term) {
echo \'<li><a href="\' . get_term_link( $term ) . \'">\' . $term->name . \'</a></li>\';
}
echo \'</ul>

是否要列出所有子类别，即当前类别中的子类别？
如果是，那么您可以使用以下简单的代码片段，帮助您列出当前帖子父类别中的所有子类别。
Code for Getting subcategories of current category
<ul id="all-sub-categories">
<?php
$postcat = get_the_category( $post->ID );
foreach ($postcat as $cat) {
if ($cat->parent != 0) {
echo "<li><a href=\'" . get_category_link( $cat->term_id ) . "\'>" . $cat->name . "</a></li>";
}
}
?>
</ul>

终于找到了解决方法。。。在侧栏模板中添加以下代码。您可以用自定义分类法替换“类别”分类法。
<?php
// get Post Object outside
$queried_object = get_queried_object();
if ( $queried_object ) {
$post_id = $queried_object->ID;
}
//Returns All Term Items for "my_taxonomy"
$term_list = wp_get_post_terms($post_id, \'category\', array("fields" => "all"));
$term_list_id = wp_get_post_terms($post_id, \'category\', array("fields" => "ids"));
echo \'<ul>\';
foreach($term_list as $term) {
$has_parent = $term->parent;
$has_childrens = get_terms( $term->taxonomy, array( \'parent\' => $term->term_id, \'hide_empty\' => false) );
// If it have parents...
if ( $has_parent ) {
// If parent category is already selected
if(in_array($has_parent, $term_list_id)){
// Do nothing
}else{
// If parent category is not selected
$parent_id = $term->parent;
$parent_term = get_term( $parent_id, \'category\' );
// Display Parent
echo \'<li><a href="\' . get_category_link( $parent_id ) . \'">\' . $parent_term->name.\'</a></li>\';
echo \'<ul>\';
// Display Children
$childrens = get_categories( array(\'child_of\' => $parent_id), \'category\' );
foreach($childrens as $children) {
echo \'<li><a href="\' . get_category_link( $children->term_id ) . \'">\' . $children->name.\'</a></li>\';
}
echo \'</ul>\';
}
}elseif ( $has_childrens ) {
// If it have childrens...
// display parent
echo \'<li><a href="\' . get_category_link( $term->term_id ) . \'">\' . $term->name.\'</a></li>\';
$childrens = get_categories( array(\'child_of\' => $parent_id), \'category\' );
echo \'<ul>\';
// Display children
foreach($has_childrens as $has_children) {
echo \'<li><a href="\' . get_category_link( $has_children->term_id ) . \'">\' . $has_children->name.\'</a></li>\';
}
echo \'</ul>\';
}else{
// No Parent No Child
echo \'<li><a href="\' . get_category_link( $term->term_id ) . \'">\' . $term->name.\'</a></li>\';
}
}
echo \'</ul>\';
?>
