CodeIgniter "The page you requested was not found." error?
提问by Ricardo
I'm having a problem with CodeIgniter. I've checked every possible solution on the internet and seems like nothing helps in my case. I'm not a big pro and it's my first time using CodeIgniter so don't be harsh with me.
我在使用 CodeIgniter 时遇到了问题。我已经检查了互联网上所有可能的解决方案，似乎对我的情况没有任何帮助。我不是专业人士，这是我第一次使用 CodeIgniter，所以不要对我太苛刻。
routes.php:
路线.php：
$route['default_controller'] = "page";
$route['404_override'] = '';
$route['(:num)'] = "page/index/";
page.php:
页面.php：
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Page extends CI_Controller {
public function index($id=null) {
$this->load->model('Image','',TRUE);
$this->load->model('Banner','',TRUE);
$image = $this->Image->getImageById($id);
if (empty($image)) {
show_404();
}
//db table `banner` always have three rows
$banners=$this->Banner->getBanners();
$data=array();
$data['image']=$image;
$data['banner']=$banners;
$this->load->view('page_index', $data);
}
}

I have read your problem. You have done mistake while saving the controller.
我已经阅读了你的问题。您在保存控制器时犯了错误。
It should be saved in capital i.e. Page.phpbut you have saved as page.php
它应该保存在资本中，即Page.php但您已保存为page.php
I think this will work out !
我想这会解决的！

If you have developed your application on Windows, you might have not set first character of Controllers and Models name as a capital character.
如果您在 Windows 上开发了您的应用程序，您可能没有将控制器和模型名称的第一个字符设置为capital character.
like /controllers/home.phpto /controllers/Home.php
像/controllers/home.php到/controllers/Home.php
On Linux file names are case sensitive.
在 Linux 上，文件名区分大小写。
Note:- This is a solution to a possible problem. There may be issues of mis configuration, server and path variables.
注意：- 这是对可能出现的问题的解决方案。可能存在配置错误、服务器和路径变量的问题。

Did you construct the parent? Public function _construct() { Parent::_construct(); }
你构造了父级吗？公共函数_construct() { Parent::_ construct(); }

Thank you everyone, The problem was that i stated in page.php that if there is no images in the database it'll show 404 page:
谢谢大家，问题是我在page.php中声明，如果数据库中没有图像，它将显示404页面：
if (empty($image)) {
show_404();
}
I've added two images to the DB and now it works.
我已经向数据库添加了两个图像，现在它可以工作了。

This doesn't sound like a Codeigniter error. It could be your webserver configuration. Do you have a webserver and php server setup and configured on your machine? Have you configured an .htaccess file to replace "index.php"?
这听起来不像是 Codeigniter 错误。这可能是您的网络服务器配置。您是否在您的机器上设置并配置了网络服务器和 php 服务器？您是否配置了 .htaccess 文件来替换“index.php”？

I am also quite new to codeigniter. This is what I would do at the beginning:
我对 codeigniter 也很陌生。这就是我一开始会做的事情：
- autoload database and configure the database.php file
- autoload helper file 'url', 'file'
- configure your base url "://yourhost/yourworkingfolder" (if you are working on local host)
- You need to route your page. Go to route.php, and give the name of your default controller page name and if it seems working than you r good to further with additional task.
- 自动加载数据库并配置database.php文件
- 自动加载帮助文件 'url', 'file'
- 配置您的基本网址“://yourhost/yourworkingfolder”（如果您在本地主机上工作）
- 您需要路由您的页面。转到 route.php，并提供您的默认控制器页面名称，如果它看起来有效，那么您可以进一步执行其他任务。
Please, correct me if I am wrong. I am a newbie to codeigniter. Thankx
如果我错了，请纠正我。我是 codeigniter 的新手。谢谢

the controller will uppercase first letter if you are using Unix server
如果您使用的是 Unix 服务器，控制器将大写第一个字母
