php - CodeIgniter manage records from database

Question

I am having a trouble coming up with the concept of this. My application is stored in http://localhost (duh) and I have an admin panel, which can be accessed by going to http://localhost/admin. I have admin panel menu and one of the menus is Manage Pages, accessed by going to http://localhost/admin/manage_pages. Manage Pages page brings up results from database which have title, description and ID. Now, my question is, if I want to edit lets say the third row's title, how would I do this? would it be http://localhost/admin/manage_pages/3? But for that case I would have to create a function in controller? I am confused.

Answer 1

如果您喜欢 URI 的格式：localhost/admin/manage_pages/3，那么您唯一缺少的就是为您的控制器函数接受一个变量。在这种情况下，如果没有传递任何内容，我更喜欢设置默认值，并且使用 if else 语句，您有一个方法可以加载指定页面，或者在没有传递任何内容时加载所有页面。

控制器管理员：

public function manage_pages($page_id='')
{
    if ($page_id == '')
    {    LOAD ALL RESULTS }
    else
    {    LOAD 1 RESULT    }
}
