Codeigniter 3.0.4，在我的服务器上找不到404页错误

Question

I am new to the codeigniter. After developing a web app on my localhost .So i uploaded my site on server and then i imported my database. after that i have changed the settings of database in database.php file .. and also i changed the base url in config.php file.

I am getting a 404 Page Not Found. The page you requested was not found . I dont know what is going wrong ..i have searched a lot but nothing helps. and my .htaccess file is empty ..means there is not a single line in it. and one more thing is that i purchase this from godaddy hosting may be helpfull.

my routes.php

$route['default_controller'] = '';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;

my controller doctorscont.php

<?php defined('BASEPATH') OR exit('No direct script access allowed');

class Doctorscont extends CI_Controller {

   public function index() { 
         here is my code.....  */
   }
}

and my config > config.php

$config['base_url'] = ''; 
$config['index_page'] = 'index.php';

Answer 1

You have to define doctorscont's route in routes.php.

Please add this line at the end of routes.php then visit

$route['doctorscont'] = 'Doctorscont';

If you still get 404 error, please try If it opens, you may want to remove index.php on URL. For this task, visit CodeIgniter URLs Guide

Edit:

Create a .htaccess file under your root (same folder with system and application) with the content below:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

Than open config.php and edit this line:

$config['index_page'] = 'index.php';

to this:

$config['index_page'] = '';

Now you can get what you want.

Answer 2

In version 3+ the filenames must contain the first letter of each file as upper case. It will work in lowercase in your localhost environment but not on server.

Rename the file to ' D octorscont.php' and you can use the class names as lowercase .

class Doctorscont extends CI_Controller

It seems you have not made some changes at apache2 config level please do below changes.

1)sudo a2enmod rewrite

2)gedit /etc/apache2/apache2.conf

3)add below to end of your conf file

 <Directory /var/www/html/> AllowOverride All </Directory> 

4) Restart apache2 service by below command. service apache2 restart

Best of luck.
