自定义分类法不显示在自定义post循环中。

Question

所以我想我可能要疯了什么的。我有一个定制的post类型(arkiv)，它有两个自定义分类(类型和作者)，我试图在循环中的模板页面上列出文章，并显示帖子标题和两个分类，但我无法让它工作。文章的标题是列出的，但没有分类。

我的CPT看起来是这样的：

function post_archive() {
  $labels = array(
    'name'                => _x( 'Arkiv & Samlingar', 'twentytwenty' ),
    'singular_name'       => _x( 'Arkiv & Samlingar', 'twentytwenty' ),
    'menu_name'           => __( 'Arkiv & Samlingar', 'twentytwenty' ),
    'all_items'           => __( 'Alla Arkiv & Samlingar', 'twentytwenty' ),
    'view_item'           => __( 'Visa Arkiv & Samlingar', 'twentytwenty' ),
    'add_new_item'        => __( 'Lägg till Arkiv & Samlingar', 'twentytwenty' ),
    'add_new'             => __( 'Lägg till Arkiv & Samlingar', 'twentytwenty' ),
    'edit_item'           => __( 'Ändra Arkiv & Samlingar', 'twentytwenty' ),
    'update_item'         => __( 'Uppdatera Arkiv & Samlingar', 'twentytwenty' ),
    'search_items'        => __( 'Sök Arkiv & Samlingar', 'twentytwenty' ),
    'not_found'           => __( 'Fann inget', 'twentytwenty' ),
    'not_found_in_trash'  => __( 'Fann inget i Papperskorgen', 'twentytwenty' ),
  ); 
  $args = array(
    'label'               => __( 'arkiv', 'twentytwenty' ),
    'labels'              => $labels,
    'supports'            => array( 'title', 'editor', 'excerpt', 'author', 'thumbnail', 'comments', 'revisions', 'custom-fields', ),
    'hierarchical'        => false,
    'public'              => true,
    'show_ui'             => true,
    'show_in_menu'        => true,
    'show_in_nav_menus'   => true,
    'show_in_admin_bar'   => true,
    'menu_icon'           => 'dashicons-book',
    'menu_position'       => 5,
    'can_export'          => true,
    'has_archive'         => false,
    'exclude_from_search' => false,
    'publicly_queryable'  => true,
    'capability_type'     => 'post',
    'show_in_rest'        => true,
    'taxonomies'          => array('genre', 'author'),
  );   
  register_post_type( 'arkiv', $args );
}
add_action( 'init', 'post_archive', 0 );

我的两个分类法是这样的：

add_action( 'init', 'genre', 0 );
function genre() {
  $labels = array(
    'name' => _x( 'Subjects', 'taxonomy general name' ),
    'singular_name' => _x( 'Subject', 'taxonomy singular name' ),
    'search_items' =>  __( 'Search Subjects' ),
    'all_items' => __( 'All Subjects' ),
    'parent_item' => __( 'Parent Subject' ),
    'parent_item_colon' => __( 'Parent Subject:' ),
    'edit_item' => __( 'Edit Subject' ), 
    'update_item' => __( 'Update Subject' ),
    'add_new_item' => __( 'Add New Subject' ),
    'new_item_name' => __( 'New Subject Name' ),
    'menu_name' => __( 'Subjects' ),
  );    
  register_taxonomy('genre',array('arkiv'), array(
    'hierarchical' => true,
    'labels' => $labels,
    'show_ui' => true,
    'show_in_rest' => true,
    'show_admin_column' => true,
    'query_var' => true,
    'rewrite' => array( 'slug' => 'genre' ),
  ));
}

add_action( 'init', 'author', 0 );
function author() {
  $labels = array(
    'name' => _x( 'Subjects', 'taxonomy general name' ),
    'singular_name' => _x( 'Subject', 'taxonomy singular name' ),
    'search_items' =>  __( 'Search Subjects' ),
    'all_items' => __( 'All Subjects' ),
    'parent_item' => __( 'Parent Subject' ),
    'parent_item_colon' => __( 'Parent Subject:' ),
    'edit_item' => __( 'Edit Subject' ), 
    'update_item' => __( 'Update Subject' ),
    'add_new_item' => __( 'Add New Subject' ),
    'new_item_name' => __( 'New Subject Name' ),
    'menu_name' => __( 'Subjects' ),
  );    
  register_taxonomy('author',array('arkiv'), array(
    'hierarchical' => true,
    'labels' => $labels,
    'show_ui' => true,
    'show_in_rest' => true,
    'show_admin_column' => true,
    'query_var' => true,
    'rewrite' => array( 'slug' => 'author' ),
  ));
}

我的CPT出现了，分类法也出现了，它们在那里，我把分类法分配给那里的帖子，但是当我试图列出帖子的时候，我只得到标题而没有分类。

我的问题是：

 'arkiv', 
  'post_status' => 'publish',
  'posts_per_page' => -1, 
  'orderby' => 'date', 
  'order' => 'DESC'
);
$the_query = new WP_Query( $args ); ?>
have_posts() ) : ?>
  have_posts() ) : $the_query->the_post(); ?>
    
    
    ID, 'author', 'Author: ', ', ', ' ' ); ?>
    ID, 'genre', 'Genre: ', ', ', ' ' ); ?>

我不明白我做错了什么，谢谢。

Answer 1

在调用$post之后，您还没有公开全局$the_query->the_post()变量。

或者在调用$the_query->the_post()之后添加D3，或者用get_the_ID()替换$post->ID。
