我想输出分类法的子类别详细信息
$getTerms = get_terms($taxonomy, $args);
print_r($getTerms);
当我打印出上面的内容时，它会返回对象。但父类别和子类别之间没有价值差异。第一个是父分类法，第二个是子类别。
[1] => stdClass Object
(
[term_id] => 23
[name] => Corporate teams
[slug] => corporate-teams
[term_group] => 0
[term_taxonomy_id] => 23
[taxonomy] => team_names
[description] => Description of corporate team
[parent] => 0
[count] => 0
[image_id] => 0
)
[3] => stdClass Object
(
[term_id] => 25
[name] => Team name 1
[slug] => team-name-1
[term_group] => 0
[term_taxonomy_id] => 25
[taxonomy] => team_names
[description] => Lorem ipsum dolor sit amet, consectetur adipiscing elit. Proin nec pellentesque sapien.
[parent] => 22
[count] => 1
[image_id] => 90
)
如何查询此对象的一部分（可能作为foreach或WP\\u查询），以便返回子类别及其相关值（标题、图像等）？“get\\u terms（）”函数是否正确？

您可以使用parent 中的参数get_terms() 获得一个学期的直接子女。您可以使用child_of 参数获取一个术语的所有后代。
像这样的。
$parent_id = 32;
$args = array(
\'parent\' => $parent_id
);
$terms = get_terms( $taxonomy, $args );
print_r( $terms );
如果希望以编程方式获取父术语，并在循环中获取子类别，可以执行以下操作。
$taxonomy = \'your_tax\';
$args = array(
\'parent\' => 0 // to get only parent terms
);
$terms = get_terms( $taxonomy, $args );
foreach( $terms as $term ) {
$children = get_terms( $taxonomy, array(
\'parent\' => $term->term_id;
) );
print_r( $children );
}
