Get Categories查询在函数.php中不起作用

我正在尝试在函数中获取自定义帖子类型的类别。php，但它不返回任何值，当我在任何主题文件中运行此查询时，它工作正常。这是我的密码

function get_destinations(){
   $args = array(
    \'type\'                     => \'accomodation\',
    \'child_of\'                 => 0,
    \'parent\'                   => \'\',
    \'orderby\'                  => \'name\',
    \'order\'                    => \'ASC\',
    \'hide_empty\'               => 1,
    \'hierarchical\'             => 1,
    \'exclude\'                  => \'\',
    \'include\'                  => \'\',
    \'number\'                   => \'\',
    \'taxonomy\'                 => \'facilitie\',
    \'pad_counts\'               => false 

); 
 $categories = get_categories($args);$destinations = array();
              foreach ($categories as $cat) { 
                if($cat->cat_name != \'\'){
                    $destinations[$cat->cat_name] = $cat->cat_name;
                }
          }
return $destinations;
 }

我正在使用this 要添加的代码meta field, 现在我必须将类别传递给select 标记为

$my_meta2->addSelect($prefix.\'select_field_id\',get_destinations(),array(\'name\'=> \'Select Destination\'));

原始代码是这样的，它们在数组中传递值。

$my_meta->addSelect($prefix.\'select_field_id\',array(\'selectkey1\'=>\'Select Value1\',\'selectkey2\'=>\'Select Value2\'),array(\'name\'=> \'My select \', \'std\'=> array(\'selectkey2\')));

但没有得到任何价值，任何我错在哪里的想法。谢谢

function get_destinations(){ // Using a post type $args = array( \'type\' => \'book\', \'taxonomy\' => \'genre\', ); $categories = get_terms($args); // changed to get_terms() if (!is_wp_error()) { $destinations = wp_list_pluck($categories,\'cat_name\'); /* Convert to key=>value format I doubt this is actually necessary and can probably be omitted */ $destinations = array_combine($destinations,$destinations); return $destinations; } } var_dump(get_destinations());

$cat_args = array( \'parent\' => 0, \'hide_empty\' =>0, \'order\' => \'ASC\', ); $categories = get_categories($cat_args); foreach($categories as $category){ echo get_cat_name($category->term_id); }

function get_cat_val(){ $taxonomies = array(\'YOUR_CAT_SLUG\'); $args = array( \'order\' => \'ASC\', \'hide_empty\' => false, \'hierarchical\' => true ); $terms = get_terms($taxonomies, $args); print_r($terms); }

global $post; $term_class = array(); $terms = get_the_terms( $post->ID, \'YOUR CAT SLUG\' ); if ( $terms && ! is_wp_error( $terms ) ) { foreach ( $terms as $term ) { $term_class[] = $term->slug; } }

GET_CATEGORIES()返回“未分类”

在我的WPMU网站前端，所有类别都消失了，每个帖子都标有“未分类”。然而，这只是单曲。php，而不是在主页上。php。相同的错误发生在get_categories(), wp_list_categories() 和the_category().我试着用var_dump(get_categories()) 但就像WordPress一样，它只是认为应该这样。
