我有一个名为“news”的自定义帖子类型，还有一个名为“news category”的自定义分类法。我想创建一个wp查询，以返回特定“新闻类别”（例如“press”）的所有“新闻”帖子。有没有一种通用的方法来写这篇文章，这样我就不需要为每个“新闻类别”写一篇了？

我认为这与

$args = array(
    \'post_type\' => \'news\',
    \'news category\' => *GET THE LABEL FROM THE PAGE SLUG SOMEHOW*
);
$query = new WP_Query( $args );

function my_custom_post_news() {
$labels = array(
    \'name\'               => _x( \'News\', \'post type general name\' ),
    \'singular_name\'      => _x( \'News\', \'post type singular name\' ),
    \'add_new\'            => _x( \'Add New\', \'book\' ),
    \'add_new_item\'       => __( \'Add New News\' ),
    \'edit_item\'          => __( \'Edit News\' ),
    \'new_item\'           => __( \'New News\' ),
    \'all_items\'          => __( \'All News\' ),
    \'view_item\'          => __( \'View News\' ),
    \'search_items\'       => __( \'Search News\' ),
    \'not_found\'          => __( \'No News found\' ),
    \'not_found_in_trash\' => __( \'No News found in the Trash\' ), 
    \'parent_item_colon\'  => \'\',
    \'menu_name\'          => \'News\'
);
$args = array(
        \'labels\'        => $labels,
        \'description\'   => \'Holds our news and news specific data\',
        \'public\'        => true,
        \'menu_position\' => 5,
        \'supports\'      => array( \'title\', \'editor\', \'thumbnail\', \'excerpt\', \'comments\' ),
        \'has_archive\'   => true,
    );
    register_post_type( \'news\', $args );    
}
add_action( \'init\', \'my_custom_post_news\' );

function mav_taxonomies_news() {
    $labels = array(
        \'name\'              => _x( \'News Categories\', \'taxonomy general name\' ),
        \'singular_name\'     => _x( \'News Category\', \'taxonomy singular name\' ),
        \'search_items\'      => __( \'Search News Categories\' ),
        \'all_items\'         => __( \'All News Categories\' ),
        \'parent_item\'       => __( \'Parent News Category\' ),
        \'parent_item_colon\' => __( \'Parent News Category:\' ),
        \'edit_item\'         => __( \'Edit News Category\' ), 
        \'update_item\'       => __( \'Update News Category\' ),
        \'add_new_item\'      => __( \'Add New News Category\' ),
        \'new_item_name\'     => __( \'New News Category\' ),
        \'menu_name\'         => __( \'News Categories\' ),
    );
    $args = array(
        \'labels\' => $labels,
        \'hierarchical\' => true,
        \'has_archive\'   => true,
    );
    register_taxonomy( \'news_category\', \'news\', $args );
    register_taxonomy_for_object_type( \'news_category\', \'news\' );
}
add_action( \'init\', \'mav_taxonomies_news\', 0 );

编辑：将“标签”更改为“新闻类别”
