You need to use get_terms($taxonomies, $args);
你需要使用 get_terms($taxonomies, $args);
$parent_term_id = 4; // term id of parent term (edited missing semi colon)
$taxonomies = array(
'category',
);
$args = array(
'parent' => $parent_term_id,
// 'child_of' => $parent_term_id,
);
$terms = get_terms($taxonomies, $args);
You could also use 'child_of'instead;
你也可以'child_of'改用;
Note: the difference between child_of and parent is that where parent only gets direct children of the parent term (ie: 1 level down), child_of gets all descendants (as many levels as are available)
注意：child_of 和 parent 之间的区别在于，parent 仅获取父项的直接子项（即：向下 1 级），child_of 获取所有后代（尽可能多的级别）
Codex: get_terms
法典：get_terms
