所以这里有一个奇怪的。我有自定义分类法，它们显示在与之关联的两种帖子类型的管理菜单上，但只有一种帖子类型在其编辑菜单中显示它们。（位于后期编辑屏幕的一侧，显示类别、标签和特色图片。）

Wordpress的全新安装。我有2个自定义分类法，“我有2个自定义分类法”；“格式”；和；地区；。我有两种帖子类型，”“；“事件”；和；资源；。

每个都设置为使用内置类别和一个或两个自定义分类法。它们都是由相同的函数生成的。

分类法和帖子正确关联-都在管理菜单和事件快速编辑中可见，只有一个用于资源-并且两个的主列元框都正确显示并存储其值。“我可以手动”；标签（&Q）；在快速编辑中按预期进行。

但自定义分类法仅可在其中一个的编辑后GUI中进行选择。事件同时显示自定义分类法和内置类别，资源仅显示内置类别。

下面是注册分类的代码：

function rdcfp_register_custom_taxonomy ($name, $singular_name, $hierarchical, $associated_types) {

    $labels = array(
        \'name\'          => $name, 
        \'singular_name\' => $singular_name, 
        \'add_new_item\'  => \'Add New \' . $singular_name, 
        \'edit_item\'     => \'Edit \' . $singular_name, 
        \'view\'          => \'View\', 
        \'view_item\'     => \'View\' . $singular_name , 
        \'search_items\'  => \'Search \' . $name, 
        \'menu_name\'     => $name         
    );  
    $args = array(
        \'label\'             => $name,
        \'labels\'            => $labels,
        \'show_ui\'           => true,
        \'public\'            => true, 
        \'hierarchical\'      => $hierarchical,
        \'show_admin_column\' => true,
        \'query_var\'         => true,
        \'rewrite\'           => array( \'slug\' => $name ),

    );    

    register_taxonomy($name, $associated_types, $args);

}

function rdcfp_register_region_taxonomy(){
    rdcfp_register_custom_taxonomy (\'Regions\', \'Region\', false, array(\'events\'));
}
function rdcfp_register_format_taxonomy(){
    rdcfp_register_custom_taxonomy (\'Formats\', \'Format\', false, array(\'events\', \'resources\'));
}

以下是注册帖子类型的代码：

function rdcfp_create_custom_post_type($name, $singular_name, $description, $hierarchical, $taxonomies, $supports, $menu_icon) {


    $labels = array(
        \'name\'          => $name, 
        \'singular_name\' => $singular_name, 
        \'add_new_item\'  => \'Add New \' . $singular_name, 
        \'edit_item\'     => \'Edit \' . $singular_name, 
        \'view\'          => \'View\', 
        \'view_item\'     => \'View\' . $singular_name , 
        \'search_items\'  => \'Search \' . $name, 
        \'not_found\'     => \'No \' . $name . \' found\' , 
        \'not_found_in_trash\' => \'No \' . $name . \' found in trash\'        
        ); 

    $args = array(
        \'label\'                 => $name,
        \'labels\'                => $labels,
        \'public\'                => true, 
        \'hierarchical\'          => $hierarchical,
        \'public\'                => true,
        \'show_ui\'               => true,
        \'show_in_menu\'          => true,
        \'show_in_nav_menus\'     => true,
        \'show_in_admin_bar\'     => true,
        \'menu_position\'         => 5,
        \'can_export\'            => true,
        \'has_archive\'           => true,
        \'exclude_from_search\'   => false,
        \'publicly_queryable\'    => true,
        \'capability_type\'       => \'post\',
        \'show_in_rest\'          => true, 
        \'description\'           => $description,
        \'supports\'              => $supports,
        \'taxonomies\'            => $taxonomies,
        \'menu_icon\'             => $menu_icon
        );

    register_post_type ($name, $args);

}

function rdcfp_create_events_post_type (){

    $name = \'Events\';
    $singular_name = \'Event\';
    $description = \'A custom post type for Sales events.\';
    $hierarchical = false;
    $taxonomies = array(\'formats\',\'regions\', \'category\');
    $supports   = array(\'title\', \'featured-image\', \'thumbnail\', \'excerpt\');
    $menu_icon = \'dashicons-calendar-alt\';

    rdcfp_create_custom_post_type($name, $singular_name, $description, $hierarchical, $taxonomies, $supports, $menu_icon);
    

}

function rdcfp_create_resources_post_type (){

    $name = \'Resources\';
    $singular_name = \'Resource\';
    $description = \'A custom post type for consideration-stage content.\';
    $hierarchical = false;
    $taxonomies = array(\'formats\',\'category\');
    $supports   = array(\'title\', \'editor\',\'featured-image\', \'thumbnail\', \'excerpt\');
    $menu_icon = \'dashicons-visibility\';

    rdcfp_create_custom_post_type($name, $singular_name, $description, $hierarchical, $taxonomies, $supports, $menu_icon);
    
}

两者都有自定义的元框，但这些字段都按预期显示和存储值。

最后是行动，以防我在那里出错：

add_action(\'init\', \'rdcfp_create_events_post_type\');
add_action(\'init\', \'rdcfp_create_resources_post_type\');
add_action(\'init\', \'rdcfp_register_region_taxonomy\', 0);
add_action(\'init\', \'rdcfp_register_format_taxonomy\', 0);

当这种奇怪的事情发生时，我通常可以在某处发现一种类型或放弃的论点，但我被难住了。有什么提示吗？

function rdcfp_register_custom_taxonomy ($name, $singular_name, $hierarchical, $associated_types) {

    $labels = ... your code;
    $args = array(
        \'label\'             => $name,
        \'labels\'            => $labels,
        \'show_ui\'           => true,
        \'public\'            => true,
        \'hierarchical\'      => $hierarchical,
        \'show_admin_column\' => true,
        \'query_var\'         => true,
        \'rewrite\'           => array( \'slug\' => $name ),
        \'show_in_rest\'      => true, // add this line

    );

    register_taxonomy($name, $associated_types, $args);

}
