我有一个问题，我试图为seo创建干净的URL。但是我没有使用get获取任何参数，这在我的代码中是错误的

add_action( \'init\', \'listing_search_url\' );
  function listing_search_url()
  {
    add_rewrite_tag(\'%type%\', \'([^&]+)\');
    add_rewrite_tag(\'%search_location%\', \'([^&]+)\');
    add_rewrite_rule(
        \'^custom(/([^/]+))?/(/([^/]+))?/?\',
        \'index.php?page_id=23&type=$matches[2]&search_location=$matches[4]\',
        \'top\'
    );
    flush_rewrite_rules();
  }

这项工作，但有错误，所以我只是做了一个改变，工作完美

function wpd_foo_get_param() {
    if( false !== get_query_var( \'search_location\' ) ){
        $_GET[\'search_location\'] = get_query_var( \'search_location\' );
    }
}
add_action( \'parse_query\', \'wpd_foo_get_param\' );

此代码有效

add_action( \'parse_query\', \'listing_get_query_vars\' );
 function listing_get_query_vars() {
     //if you use - _ + on your url the form just recive a space
    if(!empty( get_query_var( \'search_location\' )) ){
        $_GET[\'search_location\'] = str_replace(array(\'-\',\'_\',\'+\'),\' \',get_query_var( \'search_location\' ));
    } 
}

function wpd_foo_get_param() {
    if( false !== get_query_var( \'search_location\' ) ){
        $_GET[\'search_location\'] = get_query_var( \'search_location\' );
    }
}
add_action( \'parse_query\', \'wpd_foo_get_param\' );
