在CodeIgniter中构建一个菜单

Question

main_view

<table width="1100" border="1" align="center">
  <tr><?php $this->load->view('header_view'); ?></tr>
  <tr><?php $this->load->view('menu_view'); ?></tr>
  <tr>
    <td colspan="2"  id="content">
      <?php
            $a = ($_GET['pages/']);
            switch($a)
        {
                case "home":
                  require("pages/home");
                  break;
                case "about":
                  require("pages/about");
                  break;
         }
         ?>
    </td>
    <?php $this->load->view('rightMenu_view'); ?></tr>
  <tr><?php $this->load->view('footer_view'); ?></tr>
</table>

menu_view

 <div id="menu">
    <ul>
        <li><a href="pages/home">Home</a></li>
        <li><a href="pages/about">About</a></li>
        <li><a href="pages/staff">Staff</a></li>
        <li><a href="pages/chat">Chat</a></li>
        <li><a href="pages/championat">Championat</a></li>
        <li><a href="pages/contact">Contact</a></li>
    </ul>
</div>

pages_controller

class Pages extends CI_Controller
{
    public function __construct()
    {
        parent::__construct();
        $this->load->helper('html');
        $this->load->helper('url');
        $this->load->helper('form');
    }
    public function index()
    {
        $this->load->view('main_view');
    }
    public function home() { echo "Hello"; }
    public function about() { echo "Hello about"; }
}

I want to switch to other option in menu and only change the column td id="content" with the content. But it doesn't work.

I think the error is at switch.

I did something similar but I have not ever used a framework

Firstly, it isn't semantic HTML to use tables as a formatting method. it is best to avoid it.

codeigniter has a $this->input->get('variablename'); which is a bit more secure than $_GET(), and returns FALSE if the GET is not set.

a get call in the URL requires ?name1=value1 in the URL. you are not using this, which is probably why it is not working.

CI does allow parameters in controller methods. look into it, you can put the switch in your Pages::index method.
