Drupal:分层分类面包屑路径 [英] Drupal: Hierarchical taxonomical breadcrumb trail

问题描述

当我只有孩子"的 TID 时，我希望从分类术语(例如祖父母/父母/孩子)生成分层面包屑.我一直在玩弄taxonomy_get_tree()，但如果没有非常繁重的迭代，似乎很难做到.必须有更简单的方法.

I'm looking to generate a hierarchical breadcrumb from a taxonomy term (e.g. grandparent/parent/child) when all I have is the TID of "child". I've been toying around with taxonomy_get_tree(), but it seems quite difficult to do without very heavy iteration. There has to be an easier way.

想法?

谢谢！

推荐答案

这就是我所做的:

$breadcrumb[] = l(t('Home'), NULL);
if ($parents = taxonomy_get_parents_all($tid)) {
  $parents = array_reverse($parents);
  foreach ($parents as $p) {
    $breadcrumb[] = l($p->name, 'taxonomy/term/'. $p->tid);
  }
}
drupal_set_breadcrumb($breadcrumb);

我通常会将它放在 hook_view() 函数或 hook_nodeapi($op="view") 函数中.

I'll typically stick this in a hook_view() function or hook_nodeapi($op="view") function.
