在 WordPress 中获取类别 ID 数组？

$cats=  get_categories(array(
    'order'                    => 'ASC',
    'orderby'                  => 'id',

    'hierarchical'             => 0,
    'hide_empty'               => 0,
    'taxonomy'                 => 'edu_year'
));

我想生成一个变量，其中包含从 get_categories 函数检索到的值的 ID 数组。

根据它返回的文档：

$category->term_id
$category->name
$category->slug
$category->term_group
$category->term_taxonomy_id
$category->taxonomy
$category->description
$category->parent
$category->count
$category->cat_ID
$category->category_count
$category->category_description
$category->cat_name
$category->category_nicename
$category->category_parent

So:

$output_categories = array();
$categories=get_categories($args);
  foreach($categories as $category) { 
     $output_categories[$category->cat_ID] = $category->name;
}

Then $output_categories正是您所需要的。
