我无法在Wordpress中使用自定义帖子类型的类别进行筛选。当我单击类别时，它会显示所有帖子，而不是相应的类别。我使用的是自定义分类法，一直在互联网上搜索，但找不到解决方案。分页是有效的，但分类不起作用。我不知道为什么会这样。
注册自定义帖子类型
// Register Custom Post Type
function custom_post_type_music() {
$labels = array(
'name' => _x( 'Music', 'Post Type General Name', 'text_domain' ),
'singular_name' => _x( 'Music', 'Post Type Singular Name', 'text_domain' ),
'menu_name' => __( 'Music', 'text_domain' ),
'parent_item_colon' => __( 'Parent Music:', 'text_domain' ),
'all_items' => __( 'All Music', 'text_domain' ),
'view_item' => __( 'View Music', 'text_domain' ),
'add_new_item' => __( 'Add New Music Tracks', 'text_domain' ),
'add_new' => __( 'New Music Tracks', 'text_domain' ),
'edit_item' => __( 'Edit Music', 'text_domain' ),
'update_item' => __( 'Update Music', 'text_domain' ),
'search_items' => __( 'Search Music', 'text_domain' ),
'not_found' => __( 'No Music found', 'text_domain' ),
'not_found_in_trash' => __( 'No Music found in Trash', 'text_domain' ),
);
$args = array(
'label' => __( 'Music', 'text_domain' ),
'description' => __( 'Music information pages', 'text_domain' ),
'labels' => $labels,
'supports' => array( 'title', 'editor', 'thumbnail', 'comments', 'revisions', ),
'hierarchical' => true,
'public' => true,
'show_ui' => true,
'show_in_menu' => true,
'show_in_nav_menus' => true,
'show_in_admin_bar' => true,

'exclude_from_search' => false,
'publicly_queryable' => true,
'capability_type' => 'page',
);
register_post_type( 'opd-music', $args );
// Initialize Taxonomy Labels
$labels = array(
'name' => _x( 'Categories', 'taxonomy general name', 'text_domain' ),
'singular_name' => _x( 'Category', 'taxonomy singular name', 'text_domain' ),
'search_items' => __( 'Search Types', 'text_domain' ),
'all_items' => __( 'All Categories', 'text_domain' ),
'parent_item' => __( 'Parent Category', 'text_domain' ),
'parent_item_colon' => __( 'Parent Category:', 'text_domain' ),
'edit_item' => __( 'Edit Categories', 'text_domain' ),
'update_item' => __( 'Update Category', 'text_domain' ),
'add_new_item' => __( 'Add New Category', 'text_domain' ),
'new_item_name' => __( 'New Category', 'text_domain' ),
);
// Register Custom Taxonomy
register_taxonomy('tagmusic',array('opd-music'), array(
'hierarchical' => true, // define whether to use a system like tags or categories
'labels' => $labels,
'show_ui' => true,
'query_var' => true,
'rewrite' => array( 'slug' => 'cat-music' ),
));
}
// Hook into the 'init' action
add_action( 'init', 'custom_post_type_music', 0 );
自定义邮件类型查询
<? $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$args = array(
'post_type' => 'opd-music',
'order' => 'ASC',
'paged'=>$paged,
);
$q = new WP_Query($args);
$loop = new WP_Query( $args );
while ( $loop->have_posts() ) : $loop->the_post(); ?>
在上面的查询中，您没有按照自定义分类法进行任何筛选。更重要的是，你为什么要运行这个查询。
创建一个名为"taxonom-tagmusic.php"的模板文件。
然后使用正则循环。
例如
if ( have_posts() ) : while ( have_posts() ) : the_post();
当您在标签音乐分类法中查看术语时，将显示此模板文件，并为您完成查询。
add_action( 'init', 'register_cpt_music' );
