I'm not really new with Codeigniter but have been working on started projects so far. Now I'm starting a new small project on my own and I'm kinda lost.
I downloaded codeigniter, configured all the parameters in wamp so I have this base URL: http://local.project
Now I'm trying to build a small admin. I should be able to enter to this admin through http://local.project/admin which should show a login page. I already have a template for this.
The thing is that same 404 error appears. The configuration I have is this:
Inside config folder, routes.php:
$route['default_controller'] = "admin";
$route['404_override'] = '';
$route['admin'] = 'admin';
then on controllers folder, created another folder admin with a file also called admin.php which contains:
<?php
class Admin extends CI_Controller {
public function index()
{
echo 'Hello World!';
}
}
?>
now, trying to access from the browser I've tried many possible url but I'm still not sure of how it should be>
http://local.project/admin
and other combinations like
http://local.project/admin/index.php
http://local.project/index
http://local.project/index/admin
but always appears error 404 page not found.
So I'm really wondering, what am I doing wrong?
EDIT
this is what .htaccess contains>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule .* index.php/$0 [PT,L]
You're perfectly reasonable to assume that by defining a default controller it should work in subfolders, but ellislabs doesn't agree. As per the user guide:
$route['default_controller'] = 'welcome';
This route indicates which controller class should be loaded if the
URI contains no data, which will be the case when people load your
root URL. In the above example, the "welcome" class would be loaded.
You are encouraged to always have a default route otherwise a 404 page
will appear by default.
The key words there are "if the URI contains no data." "/admin" contains data. If you put your Admin controller in the root controllers folder and put in "local.project/" you'd get the index function of the Admin controller, but in a subfolder, you have to specify the full path, which in this case would be "/admin/admin/index." Putting that into your "admin" route will fix the issue, and then adding another route to take care of any other functions ($route["admin/(:any)'] = 'admin/admin/$1' should do the trick) will fix the rest.
And just so you know, if you ever upload this code to a server running Linux, it'll break because "Admin" and "admin" are two different controllers as far as Linux/Unix are concerned. As a long-time Windows dev, I feel your pain on that one.

I am having problems with codeigniter 3, I am using netbeans as my IDE and wampserver.
I was able to browser successfully to 'localhost/ci_test/' (ci_test is the name of the project/website') and it served me the default welcome.php controller,
however I tried a 2nd controller inside the CI controller folder called 'Test.php', with the following content:
<?php
class Test extends CI_Controller {
public function index() {
echo "This is default function.";
}
public function hello() {
echo "This is hello function.";
}
}
?>
then when i tried to browse to that controller: with the following url:
http://localhost/ci_test/index.php/test
it served me my welcome.php (which is not what I wanted),
then I tried this url:
http://localhost/ci_test/test.php
and I got a response:
Not Found
The requested URL /ci_test/test.php was not found on this server.
Apache/2.4.9 (Win64) PHP/5.5.12 Server at localhost Port 80
I don't understand what am I missing here...
Note: I did not change the .htacess files that were provided by codeigniter, and left them as is(maybe the problem there).
I only changed the following things in CI:
application/config/config.php:
$config['base_url'] = 'http://localhost/ci_test/';
$config['index_page'] = ''
$config['uri_protocol'] = 'PATH_INFO';
I hope someone can help here :)
EDIT:
I have read the first 4 answer's and it still doesn't work
EDIT2:
so after I decided to give up, I noticed that my apache server did not have ' mod_rewrite' ON, so i turned it on
tried again the same project and it still did not work, Then I decided to create a new project from scratch and with CI, I added new controller and everything works well now. this is lol...
Thank you very much for all those who tried to help me :)
You need to access that Test Controller directly then you need to add .htaccess file in the project root..
here is the .htaccess file for avoiding index.php in codeigniter
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
if you add this .htaccess file in the root your problem will resolved..
also don't need to add extention in your url (http://localhost/ci_test/test.php) , this is wrong
http://localhost/ci_test/test
this is enough to load your controller
welcome controller
<?php
class Welcome extends MY_Controller
{
public function index()
{
$this->load->view('welcome');
}
}
welcome view
Test Page
test controller
<?php
class Test extends MY_Controller
{
public function index()
{
$this->load->view('test');
}
}
test view
<h1>Test Page</h1>
The views must be named test.php and welcome.php and placed into the views folder.
Let us know how you get on.
Have a look at the routes.php file in the config folder
Change $route['default_controller'] = 'welcome';
to
$route['default_controller'] = 'test';
See if that works
If you get an error saying it can't find the page look at the address bar if it is like this
http://localhost/ci_test/test
try changing it to this
http://localhost/index.php/ci_test/test
Out of the box, codeigniter uses the url . com/controller/method.
You have created a Test controller called Test.php.
To access it you would use...
http://localhost/ci_test/test
You Do Not put a .php on the end.
This is a rushed quick answer... If you are using WAMPServer, check that it hasn't set MultiViews in either your httpd file or the vhosts file if you are using that.
I was using small letter for controller file name before,
however, recently move the file to other server that need to controller name to be start with capital
=========================================
Here is the rename example :
file name: Home.php
$route['default_controller']: "home";
link: http://example.com/index_folder/
==========================================
it show error of
Unable to load your default controller. Please make sure the controller specified in your Routes.php file is valid.
And when I change the route to
$route['default_controller']: "Home";
it still show the same error,
Only success if I go to
http://example.com/index_folder/Home/
How to fix that? Thanks for helping
Update
Here is the htaccess file, at the root of the project folder:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
The reason of rename is it seems the new server has problem if my Controller is in lower case
Linux is case sensitive, keep the file name and class name same and try again. It will work.
The same code will work fine on windows but give exception on Linux.
As per Documentation,
class Home extends CI_Controller {
public function index()
{
echo 'Hello World!';
}
}
Then save the file to your application/controllers/ directory.
Important:-
The file must be called ‘Home.php’, with a capital ‘H’.
Now visit the your site using a URL similar to this:
example.com/index.php/home/
CodeIgniter can be told to load a default controller when a URI is not present, as will be the case when only your site root URL is requested.
To specify a default controller, open your application/config/routes.php file and set this variable:
$route['default_controller'] = 'home';
Where ‘home’ is the name of the controller class you want used.
If you now load your main index.php file without specifying any URI segments you’ll see your “Hello World” message by default.
I'm trying to make any or a set of subdomains redirect to a folder inside "controllers" folder of a CI installation. I've tried a bunch of stuff found here on SO but none work for my project or have the same specs I need. Since I am a bit of a noob when it comes to .htaccess so I've figured I might just ask someone more qualified in here. Here are the specs:
using this awesome .htaccess file as a base
need to redirect at least this three subdomains (www|admin|api) to /application/controllers/(www|admin|api) equivalent folders
without loosing the REQUEST_URI (just saying)
and without actually changing the URL in the address bar
Example: http://api.domain.com/some/uri/segments should internally redirect to CI_installation_folder/application/controllers/api/some/uri/segments
I've tried something like this (and variations):
RewriteCond %{HTTP_HOST} ^(www|admin|api) [NC]
RewriteRule ^(.*)$ /%1/$1 [L,R=301]
or replaced the RewriteRule with 2 other lines like so:
RewriteCond %{ENV:REDIRECTED} !true
RewriteRule ^(.*)$ [L,R=301,E=REDIRECTED:true]
to prevent the loop, but all I can get is either a looping redirect (1st case) or even a 500 server error on some variations :(
Adding this
RewriteCond %{REQUEST_URI} !^/(www|admin|api) [NC]
will also not work since I'm not changing the URL in the address bar. I also haven't got any success with the [P] flag also.
Can anyone help? Thanks!
Did you try using the route configuration of Codeigniter?
you don't have to use htaccess rewrite - although its a valid approach, you can just check for the subdomain in the config/route.php file and set the routing for your subdomains.
switch ($_SERVER['HTTP_HOST']) {
case 'admin.domain.com':
$route['(:any)'] = "admin/$1"; // this will set any uri and add the controler fodler to it
$route['default_controller'] = "admin/home"; // set the default controller for this subdomain
break;
case 'api.domain.com':
$route['(:any)'] = "api/$1"; // this will set any uri and add the controler fodler to it
$route['default_controller'] = "api/home"; // set the default controller for this subdomain
break;
}
If you would like it to be a more generic/ dynamic routing, you can have it like this (in the same config/route.php file):
$controllerFolderName = array_shift((explode(".",$_SERVER['HTTP_HOST'])));
$route['(:any)'] = $controllerFolderName."/$1";
$route['default_controller'] = $controllerFolderName."/home";
this routing will work for all subdomains and will set the default routing to a folder inside the controller folder with the same name as the subdomain, so for a domain like api.domain.com you will have the route set to api etc.
it is important that you keep the same logic for all folder name that they will always match your subdomain and i would also suggest to add an error handling system for visitors with no subdomain (http://domain.com) and for cases where you have the subdomain but a folder with that name does not exists (you can do that with file_exits)
After a few more hours of digging I think I solved the problem. Here's how (for the ones that care):
# Subdomains to Folders + Enforce www
RewriteCond %{HTTP_HOST} ^(www|admin|api) [NC]
RewriteRule ^(.*)$ http://www.localhost/%1/$1 [L,P,S=1]
RewriteRule ^(.*)$ http://www.localhost/$1 [L,R=301]
I combined the internal redirect with the www enforcer rule. All there is to do after this is configure the Apache Server to accept and properly redirect the PROXY request :)
Have phun!
Tried the suggestions above but ran into a lot of issues. Found a solution that allows you to route all URIs to a directory based on the subdomain, while allowing you to use the codeigniter routing functionality as it was intended.
First, place the follwing code in your application/core folder:
class MY_Router extends CI_Router {
public function __construct($routing=NULL) {
$routing['directory'] = explode('.',$_SERVER['HTTP_HOST'])[0];
parent::__construct($routing);
}
}
Codeigniter will now place you subdomain directory before all controllers when routing. (i.e. ...application/subdomain_dir/class/method)
Next, set your base_url in the config.php file.
$subdomain = explode('.',$_SERVER['HTTP_HOST'])[0];
$config['base_url'] = 'http://'.$subdomain.'.domain.com';
Finally, use the routes.php as it was intended.
$route['default_controller'] = "home";
The default controller above will now be routed to subdomain_dir/home. Similarly, if you navigate to subdomain.domain.com/class/method, you will be routed to subdomain_dir/class/method.
Hope this helps someone in the future.
This is the error that i am getting.
Please make sure the controller specified in your Routes.php file is valid.
Let me explain this.
In my application i have used HMVC. In my application folder there are two folders back-modules and front-modules.in my front-modules folder there is a folder called "home" and it has controllers,modules and views.
controllers->home.php
this is my home.php
class Home extends MX_Controller{
public function __construct(){
parent::__construct();
$this->load->helper(array('form'));
}
public function index(){
$this->template->build('home');
}
}
and this is my routes.php
$route['default_controller'] = "home";
$route['404_override'] = '';
when i try to go to the site, it gives this error
unable to load your default controller on Codeigniter.Please make sure the controller specified in your Routes.php file is valid.
this system works fine on localhost.
Someone please help me in this matter.
Typically there is a one-to-one relationship between a URL string and its corresponding controller class/method. The segments in a URI normally follow this pattern:
example.com/class/function/id/
your 'default_controller' should be:
$route['default_controller'] = "home/index";
read official CodeIgniter URI Routing Documentation
Kindly Check .htaccess file exist or not in root place of your website.
RewriteEngine on
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?$1
Some times codeigniter won't find the controller.
Go to config > routers.php
and see the value of default_controller
make a controller in controllers folder with the same value.
According to codegniter manual managing multi application
in your index.php file change
$application_folder = 'application';
to
$application_folder = 'application/home';
and make sure the controller file name starts with capital letter
controllers->Home.php
and keep Routes.php configurations
$route['default_controller'] = "home";
I have my routes.php as
$route['home'] = 'pages/home';
$route['login'] = 'pages/login';
$route['default_controller'] = 'pages/home';
and the controller pages.php as
class Pages extends CI_Controller {
public function home() {
$this->load->view('templates/header');
$this->load->view('pages/home');
$this->load->view('templates/one');
$this->load->view('templates/two');
$this->load->view('templates/footer');
}
public function login() {
//if ( ! file_exists('application/views/templates/'.$page.'.php')) {
// echo "no file";
// }
// $data['title'] = ucfirst($page);
$this->load->view('templates/header');
$this->load->view('templates/login');
$this->load->view('templates/footer');
}
}
Pre: I have just started with CodeIgniter and what I got from basic tutorial and after reading many stackoverflow answers is that a call for domain/login will be routed to function login in Pages class(controler) as per the the routing rule $route['login'] = 'pages/login';
The Problem: This simple code is showing 404 error. I am not getting it why it is so, as all the files are too present in templates folder. Also the normal call to domain works fine but if I call domain/home, again I get 404 error. Kindly help me what I am doing wrong.
So I am a bit new to CodeIgniter as well so I apologize at being so slow on this. The problem you are facing is that you haven't put in index.php. Your URL has to be domain/index.php/login. If you don't want to add index.php to every call then you must do the following:
add a .htaccess file in your application folder and have it look something like this:
<IfModule mod_rewrite.c>
# activate URL rewriting
RewriteEngine on
# the folders mentioned here will be accessible and not rewritten
RewriteCond $1 !^(resources|system|application|ext)
# do not rewrite for php files in the document root, robots.txt or the maintenance page
RewriteCond $1 !^([^\..]+\.php|robots\.txt)
# but rewrite everything else
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
<IfModule !mod_rewrite.c>
# If we don't have mod_rewrite installed, all 404's
# can be sent to index.php, and everything works as normal.
ErrorDocument 404 index.php
</IfModule>
Turn on mode_rewrite (How to enable mod_rewrite for Apache 2.2 or https://askubuntu.com/questions/48362/how-to-enable-mod-rewrite-in-apache)
Restart your server
This will forward all domain/login requests to your front controller (index.php). The line RewriteCond $1 !^(resources|system|application|ext) will allow you to make certain folders NOT get rewritten. So if you have a folder under application named "resources" instead of it getting forwarded to domain/index.php/resources it will simply go to domain/resources.
In actuality without an .htaccess file the process is like this:
Check for domain/front_controller/route pattern in the URI and see if route exists and forward appropriately
By doing domain/login you were not following the pattern and so a 404 was delivered. Adding the front_controller (index.php) to the URI makes it follow the route pattern and gets forwarded to your route config.
Some people think the front controller in their URI is "ugly" so they add in a mod_rewrite which basically adds in the front_controller to the URI every time that directory is accessed. This way they can stick to domain/controller/action. This is also considered more secure as the only directories that can be directly accessed are the ones that are specifically stated in the rewrite.
Got it now !
Actually defining the
base_url = 'mysite.com'
in config.php just works for calling the default_controller in routing rule, and so your while mysite.com call will work normal and show you the home page, *interpreting default_controller* routing rule, but any calls for mysite.com/xyz will fail, even you have a function xyz in the main controller with routing rule as $route['xyz'] = 'pages/home',
as rest all URL calls have to be made as
domain/index.php/controller/function/arg,
and as suggested by #Bill Garrison, and also from the developer user guide of codeigniter, one should write rules in the .htaccess to remove index.php from domain name, and the url to router will then work as normal !!
For people reading out, one big advice well read the documentation thoroughly before firing the doubts. :)
