如何更改WordPress中的漂亮网址等搜索网址？

Question

我想将搜索网址更改为漂亮的网址

搜索网址示例：
http://example.com/office-search/?real_country=singapore&real_city=any

漂亮的网址如：
http://example.com/office-search/singapore/any

我还写了一条重写规则，但它对我不起作用：

function search_url_rewrite_rule() {
    if (is_search() && !empty($_GET['real_country']) || !empty($_GET['real_city']) || !empty($_GET['real_district'])) {

        $c = $_GET['real_country'];
        $city =  $_GET['real_city'];
        $district =  $_GET['real_district'];

        wp_redirect( home_url("/office-search/?".$c."/".$city."/".$district) . urlencode( get_query_var('real_country') ) );
        exit();
    };
}
add_action('template_redirect', 'search_url_rewrite_rule');
