Wordpress:提交后，我如何在搜索表单中保留市场复选框

我创建了一个带有自定义分类法的自定义帖子类型和一个用于在检查表中获取分类法术语的函数。在searchform中，我用手风琴调用这个函数。我的问题是，当我喜欢在搜索表单中保留市场复选框时。主题是儿童主题Avada。我该怎么做？

我的功能.php

/*===================================================
Show taxonomies in checklist
=====================================================*/
function get_terms_checklist($taxonomies, $args){
 $myterms = get_terms($taxonomies, $args);
 $output ="<fieldset name='".$taxonomies."'><ul>";
 foreach($myterms as $term){
  $root_url = get_bloginfo('url');
  $term_taxonomy=$term->taxonomy;
  $term_slug=$term->slug;
  $term_name =$term->name;
  $link = $term_slug;
  $key=$taxonomies;
  $output .="<li><input name='".$key."' type='checkbox' value='".$link."' />".$term_name."</li>";
 }     
 return $output;
