在模板中尝试此代码。确保用相应的slug替换post\\u类型和自定义分类法（service&county）。

    $page_link = get_permalink();
    $services = get_terms( \'service\' );
    $counties = get_terms( \'counties\' );

    $args = array();
    $args[\'post_type\'] = \'business\';
    $args[\'paged\'] = ( get_query_var( \'paged\' ) ) ? get_query_var( \'paged\' ) : 1;
    if ( isset( $_GET[\'service\'] ) ) {
        $args[\'service\'] = $_GET[\'service\'];
        $page_link = add_query_arg( \'service\', $_GET[\'service\'], $page_link );
    }
    if ( isset( $_GET[\'county\'] ) ) {
        $args[\'county\'] = $_GET[\'county\'];
        $page_link = add_query_arg( \'county\', $_GET[\'county\'], $page_link );
    }

    if ( is_array( $services ) ) {
        echo \'<ul>\';
        foreach ( $services as $service ) {
            echo \'<li><a href="\' . htmlentities( add_query_arg( \'service\', $service->slug, $page_link ) ) . \'">\' . $service->name . \'</a></li>\';
        }
        echo \'<li><a href="\' . htmlentities( remove_query_arg( \'service\', $page_link ) ) . \'">None</a></li>\';
        echo \'</ul>\';
    }

    if ( is_array( $counties ) ) {
        echo \'<ul>\';
        foreach ( $counties as $county ){
            echo \'<li><a href="\' . htmlentities( add_query_arg( \'county\', $county->slug, $page_link ) ) . \'">\' . $county->name . \'</a></li>\';
        }
        echo \'<li><a href="\' . htmlentities( remove_query_arg( \'county\', $page_link ) ) . \'">None</a></li>\';
        echo \'</ul>\';
    }

    query_posts( $args );
    if ( have_posts() ){
        while ( have_posts() ) {
            the_post();
            // Do Something
            // Pagination
        } 
    }
