我对Codeigniter错误404页面错误有疑问。
我正在创建从数据库中获取数据的动态页面。但是在所有动态页面上找不到显示404页面的页面。
请参见下面的代码。
================================================ ================
我的routes.php文件代码：
<?php
defined('BASEPATH') OR exit('No direct script access allowed');

| URI ROUTING
| -------------------------------------------------------------------------
| This file lets you re-map URI requests to specific controller functions.
|
| Typically there is a one-to-one relationship between a URL string
| and its corresponding controller class/method. The segments in a
| URL normally follow this pattern:
|
| example.com/class/method/id/
|
| In some instances, however, you may want to remap this relationship
| so that a different class/function is called than the one
| corresponding to the URL.
|
| Please see the user guide for complete details:
|
| https://codeigniter.com/user_guide/general/routing.html
|
| -------------------------------------------------------------------------
| RESERVED ROUTES
| -------------------------------------------------------------------------
|
| There are three reserved routes:
|
| $route['default_controller'] = 'welcome';
|
| This route indicates which controller class should be loaded if the
| URI contains no data. In the above example, the "welcome" class
| would be loaded.
|
| $route['404_override'] = 'errors/page_missing';
|
| This route will tell the Router which controller/method to use if those
| provided in the URL cannot be matched to a valid route.
|
| $route['translate_uri_dashes'] = FALSE;
|
| This is not exactly a route, but allows you to automatically route
| controller and method names that contain dashes. '-' isn't a valid
| class or method name character, so it requires translation.
| When you set this option to TRUE, it will replace ALL dashes in the
| controller and method URI segments.
|
| Examples: my-controller/index -> my_controller/index
| my-controller/my-method -> my_controller/my_method

$route['default_controller'] = "main"; // controller - site / method - index (404 page).
$route['404_override'] = 'main'; // same as above
$route['(iam:any)'] = 'main/index/$1';
// appending 'iam' to anything user enters. then in 'site' controller and 'user' method I will remove 'iam' from the segment and then check with database username. if found it will proceed to respective user page or else 404 page.
