How do I remove a taxonomy from Wordpress?
提问by Evan
I'm creating different custom post types and taxonomies and I want to remove the 'Post Tags' taxonomy from the default 'Posts' post type. How do I go about doing this?
我正在创建不同的自定义帖子类型和分类法，我想从默认的“帖子”帖子类型中删除“帖子标签”分类法。我该怎么做？
Thanks.
谢谢。

I suggest you don't mess with the actual global. Its safer to simply deregister the taxonomy from the post type: register_taxonomy is used for both creation and modification.
我建议你不要搞乱实际的全局。简单地从帖子类型中取消注册分类法更安全： register_taxonomy 用于创建和修改。
function ev_unregister_taxonomy(){
register_taxonomy('post_tag', array());
}
add_action('init', 'ev_unregister_taxonomy');
To remove the sidebar menu entry:
要删除侧边栏菜单条目：
// Remove menu
function remove_menus(){
remove_menu_page('edit-tags.php?taxonomy=post_tag'); // Post tags
}
add_action( 'admin_menu', 'remove_menus' );

Perhaps a more technically correct method would be to use unregister_taxonomy_for_object_type
也许技术上更正确的方法是使用 unregister_taxonomy_for_object_type
add_action( 'init', 'unregister_tags' );
function unregister_tags() {
unregister_taxonomy_for_object_type( 'post_tag', 'post' );
}

Where it says 'taxonomy_to_remove' is where you'll enter the taxonomy you want to remove. For instance you can replace it with the existing, post_tagor category.
' taxonomy_to_remove' 是您输入要删除的分类法的位置。例如，您可以将其替换为现有的post_tag或category.
add_action( 'init', 'unregister_taxonomy');
function unregister_taxonomy(){
global $wp_taxonomies;
$taxonomy = 'taxonomy_to_remove';
if ( taxonomy_exists( $taxonomy))
unset( $wp_taxonomies[$taxonomy]);
}

Total unregister and remove (minimal PHP version 5.4!)
完全注销和删除（最低 PHP 版本 5.4！）
add_action('init', function(){
global $wp_taxonomies;
unregister_taxonomy_for_object_type( 'category', 'post' );
unregister_taxonomy_for_object_type( 'post_tag', 'post' );
if ( taxonomy_exists( 'category'))
unset( $wp_taxonomies['category']);
if ( taxonomy_exists( 'post_tag'))
unset( $wp_taxonomies['post_tag']);
unregister_taxonomy('category');
unregister_taxonomy('post_tag');
});

Use it in 'admin_init' hook insetead not 'init'
在“admin_init”钩子插入而不是“init”中使用它
function unregister_taxonomy(){
register_taxonomy('post_tag', array());
}
add_action('admin_init', 'unregister_taxonomy');

add_action('admin_menu', 'remove_menu_items');
function remove_menu_items() {
remove_submenu_page('edit.php','edit-tags.php?taxonomy=post_tag');
}
add_action('admin_menu', 'remove_menu_items');
function remove_menu_items() {
remove_submenu_page('edit.php','edit-tags.php?taxonomy=post_tag');
}
