Php 具有多个URL参数的Wordpress分页格式

我正在致力于Wordpress主题的开发和实现分页。 我将URL格式更改为

http://localhost:10023/achievement?paged=2

但是现在我有了一个过滤器，它带有另一个名为

地区

的参数，比如

http://localhost:10023/achievement?prefecture=tokushima

当我转到下一页时，URL是

http://localhost:10023/achievement?prefecture=tokushima?paged=2

，包含两个

？

s，因此查询返回错误的数据

当URL有其他参数时，我需要将

？paged=2

替换为

&paged=2

我的代码如下。 谢谢你

pagination.php

<?php
  global $wp_query;
  $big = 999999999; // need an unlikely integer

  the_posts_pagination(array(
    // 'base' => str_replace( $big, '%#%', esc_url( get_pagenum_link( $big ) ) ),
    'base' => get_pagenum_link(1) . '%_%',
    'format'=> '?paged=%#%',
    'current' => max( 1, get_query_var('paged') ),
    'total' => $wp_query->max_num_pages,
    'screen_reader_text' => ' ',
    'prev_text' => __( '<i class="fa fa-arrow-left arrow"></i>', 'textdomain' ),
    'next_text' => __( '<i class="fa fa-arrow-right arrow"></i>', 'textdomain' ),
    'class' => 'custom-pagination',
  )); 
?>

// Prevent page redirect for the pagination 
function my_disable_redirect_canonical( $redirect_url ) {
  if ( is_archive() ){
    $subject = $redirect_url;
    $pattern = '/\/page\//'; // Check URL if contains /page/
    preg_match($pattern, $subject, $matches);
    
    if ($matches){
      $redirect_url = false;
      return $redirect_url;

      $query->set('meta_value', $_GET['prefecture']);
