我在体育新闻中有一篇文章.

i have a post in sport news.

当我进入体育新闻帖子时如何获得父(新闻)ID?

how to get the parent(news) id when i go into the post of sport news?

此代码回显父猫名称

      foreach((get_the_category()) as $childcat) { $parentcat = $childcat->category_parent;  
echo get_cat_name($parentcat);
echo $parentcat->term_id;}   
        echo $post->post_parent->cat_ID; 

此代码回显单页猫名

   global $post;$category = get_the_category($post->ID);echo $category[0]->name;

这个chode echo id of cat name

this chode echo id of cat name

        $category = get_the_category();    echo $category[0]->cat_ID;

推荐答案

简单，非常简单.

//firstly, load data for your child category
$child = get_category(31);

//from your child category, grab parent ID
$parent = $child->parent;

//load object for parent category
$parent_name = get_category($parent);

//grab a category name
$parent_name = $parent_name->name;

研究get_category
