我在尝试获取自定义post类型permalink时遇到分页不起作用的问题。我在这里自定义了帖子类型“songs”和自定义分类“singer”：

example.com/songs/ // 自定义帖子类型

example.com/singer/ // 自定义分类

example.com/songs/article // 后Permalink

我想让它看起来像

example.com/singer/article /// 地点com/自定义分类法/post

这是我的自定义邮件类型代码

add_action( \'init\', \'your_prefix_register_post_type\' );
function your_prefix_register_post_type() {
    $labels = [
        \'name\'                     => esc_html__( \'Songs\', \'your-textdomain\' ),

        \'rewrite\'             => array(\'slug\' => \'songs\'),
    ];

    register_post_type( \'songs\', $args );
}

和用于为post permalink重写slug的代码

function wpa_course_post_link( $post_link, $id = 0 ){
    $post = get_post($id);  
    if ( is_object( $post ) ){
        $terms = wp_get_object_terms( $post->ID, \'singer\' );
        if( $terms ){
            return str_replace( \'/songs/\' , \'/\' . $terms[0]->slug . \'/\' , $post_link );
        }
    }
    return $post_link;
}
add_filter( \'post_type_link\', \'wpa_course_post_link\', 1, 3 );

function custom_rewrite_rules() {
    add_rewrite_rule(
        \'^(.*)/(.*)/?$\',
        \'index.php?post_type=songs&name=$matches[2]\',
        \'top\'
    );
}
add_action( \'init\', \'custom_rewrite_rules\' );

感谢您的帮助。
