如何在codeigniter中重定向页面

Question

我开始在codeigniter中编码，在提交按钮后，数据应插入数据库并重定向到下一页。对我来说，插入数据库已成功完成，但页面没有重定向; 这是我的控制器 - Home.php

但是我收到错误，因为在此服务器上找不到请求的URL /代码/显示。

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Home extends CI_Controller{
    public function __construct()
    {
        parent::__construct();

    }
    public function index()
    {
        $this->load->view('demo');
        //$this->load->model('Insert_data');
    }
    public function savedata()
    {

        if($this->input->post('submit'))
        {
            $data=array(
                'name'=>$this->input->post('name'),
                'email'=>$this->input->post('email'),
                'content'=>$this->input->post('content'));

           $result=$this->Insert_data->saverecords($data);  
           if ($result)
        {
            echo "Records Saved Successfully";

            redirect(base_url().'Home/display');
        }   
        else
        {
            echo "Records not Saved Successfully";
        }
        }
    }
    public function display()
        {
            $this->load->view('display');
        }

}

<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Home extends CI_Controller{
    public function __construct()
    {
        parent::__construct();

    }
    public function index()
    {
        $this->load->view('demo');
        //$this->load->model('Insert_data');
    }
    public function savedata()
    {

        if($this->input->post('submit'))
        {
            $data=array(
                'name'=>$this->input->post('name'),
                'email'=>$this->input->post('email'),
                'content'=>$this->input->post('content'));

           $result=$this->Insert_data->saverecords($data);  
           if ($result==1)
        {
            echo "Records Saved Successfully";

            redirect('Home/display');
        }   
        else
        {
            echo "Records not Saved Successfully";
        }
        }
    }
    public function display()
        {
            $this->load->view('display');
        }

}
