我创建了两个自定义帖子类型(movie type1, movie 2) 通过functions.php, 但在创建新类别时，该类别会在帖子中重复自身(Article) 和其他CPT(movie type1, movie 2) 为什么？
function custom_post_type_week() {
// Set UI labels for Custom Post Type
$labels = array(
\'name\' => _x( \'Movie type 1\', \'Post Type General Name\', \'twentythirteen\' ),
\'singular_name\' => _x( \'Movie type 1\', \'Post Type Singular Name\', \'twentythirteen\' ),
\'menu_name\' => __( \'movie type 1\', \'twentythirteen\' ),
\'parent_item_colon\' => __( \'Parent Movie\', \'twentythirteen\' ),
\'all_items\' => __( \'All Movies\', \'twentythirteen\' ),
\'view_item\' => __( \'View Movie\', \'twentythirteen\' ),
\'add_new_item\' => __( \'Add New Movie\', \'twentythirteen\' ),
\'add_new\' => __( \'Add New\', \'twentythirteen\' ),
\'edit_item\' => __( \'Edit Movie\', \'twentythirteen\' ),
\'update_item\' => __( \'Update Movie\', \'twentythirteen\' ),
\'search_items\' => __( \'Search Movie\', \'twentythirteen\' ),
\'not_found\' => __( \'Not Found\', \'twentythirteen\' ),
\'not_found_in_trash\' => __( \'Not found in Trash\', \'twentythirteen\' ),
);
$args = array(
\'label\' => __( \'movies\', \'twentythirteen\' ),
\'description\' => __( \'Movie news and reviews\', \'twentythirteen\' ),
\'labels\' => $labels,
\'supports\' => array( \'title\', \'editor\', \'excerpt\', \'author\', \'thumbnail\', \'comments\', \'revisions\', \'custom-fields\', ),
\'hierarchical\' => true,
\'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\' => \'page\',
\'show_in_rest\' => true,
// This is where we add taxonomies to our CPT
\'taxonomies\' => array( \'category\',\'post_tag\' ),
);
register_post_type( \'movies\', $args );
}
add_action( \'init\', \'custom_post_type_week\', 0 );

Category 和post_tag 是默认的WP分类法，因为您在CPT函数中附加了它们，所以它们会出现在CPT下以及Posts菜单下
您需要做的是创建一个自定义的分类法movie_cat 并附加到您的定制CPT上，例如。movies
// Register Custom Taxonomy
function custom_taxonomy() {
$labels = array(
\'name\' => _x( \'Movie Categories\', \'Taxonomy General Name\', \'twentythirteen\' ),
\'singular_name\' => _x( \'Movie Category\', \'Taxonomy Singular Name\', \'twentythirteen\' ),
\'menu_name\' => __( \'Movie Category\', \'twentythirteen\' ),
\'all_items\' => __( \'All Items\', \'twentythirteen\' ),
\'parent_item\' => __( \'Parent Item\', \'twentythirteen\' ),
\'parent_item_colon\' => __( \'Parent Item:\', \'twentythirteen\' ),
\'new_item_name\' => __( \'New Item Name\', \'twentythirteen\' ),
\'add_new_item\' => __( \'Add New Item\', \'twentythirteen\' ),
\'edit_item\' => __( \'Edit Item\', \'twentythirteen\' ),
\'update_item\' => __( \'Update Item\', \'twentythirteen\' ),
\'view_item\' => __( \'View Item\', \'twentythirteen\' ),
\'separate_items_with_commas\' => __( \'Separate items with commas\', \'twentythirteen\' ),
\'add_or_remove_items\' => __( \'Add or remove items\', \'twentythirteen\' ),
\'choose_from_most_used\' => __( \'Choose from the most used\', \'twentythirteen\' ),
\'popular_items\' => __( \'Popular Items\', \'twentythirteen\' ),
\'search_items\' => __( \'Search Items\', \'twentythirteen\' ),
\'not_found\' => __( \'Not Found\', \'twentythirteen\' ),
\'no_terms\' => __( \'No items\', \'twentythirteen\' ),
\'items_list\' => __( \'Items list\', \'twentythirteen\' ),
\'items_list_navigation\' => __( \'Items list navigation\', \'twentythirteen\' ),
);
$args = array(
\'labels\' => $labels,
\'hierarchical\' => true,
\'public\' => true,
\'show_ui\' => true,
\'show_admin_column\' => true,
\'show_in_nav_menus\' => true,
\'show_tagcloud\' => true,
);
register_taxonomy( \'movie_cat\', array( \'movies\' ), $args );
}
add_action( \'init\', \'custom_taxonomy\', 0 );
以及在CPT函数中附加自定义分类法的部分，请使用以下代码附加
movie_cat 分类学
// This is where we add taxonomies to our CPT
\'taxonomies\' => array( \'movie_cat\' ),
