我是codeigniter的新手。我开发了一个简单的搜索表单，点击它就会显示结果。
我在表单中使用了get方法，因此在搜索时，url类似于domain/search/search\u func？keyword=test&submit=search。我想把url改成domain/search/test之类的。这里search是我的控制器，search函数是我的方法，test是get参数。我试过使用“$route['search/search_func？（：any）”]='search/search_func'；”但运气不好。。有人能帮忙吗？

html格式

<form name="search_form" action="/Search/search_func">
Search: <input type="text" placeholder="Enter keywords, city, country, etc." name="keyword">
<input type="submit" name="submit" value="Search">

控制器

<?php
defined('BASEPATH') OR exit('No direct script access allowed');

class Search extends CI_Controller {
    public function index()
    {
        $this->load->view('search');
    }
    public function search_func()
    {
        $this->load->model('Search_model');
        $result['rows'] = $this->Search_model->search_result();
        $this->load->view('search_results',$result);
    }
}
?>

型号

<?php

class Search_model extends CI_Model
{
    public function search_result(){
        $this->load->database();
        $keyword  = $this->input->get('keyword'); 
        //$query = $this->db->get("employee");
        $query = $this->db->query("select * from employee where city like '%".$keyword."%' or state like'%".$keyword."%' or country like '%".$keyword."%'");
        $results = $query->result();
        return $results;
    }
}   
?>
