I'm new to codeigniter and I'm working on a project that is done on this framework. When I try to access a url such as "mysite.com/about", it gives me and an error
404 Not found,
I tried many .htaccess file on wamp and a live host but the result is the same.
I can Access these file by using "mysite.com/index.php/about" but I want to access as this "mysite.com/about" this not only for about page but all so very page that I try to access by using like this "mysite.com/contact-us"
.How do I fix this?
Write this code in your .htaccess file and in wamp server click on rewrite_module
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
IndexIgnore *
</IfModule>
By default, Codeigniter will call the about controller, unless a method is provided in the second uri segment, the index() method will be loaded.
If the index() method doesn't exist, it will 404.
The other way of doing it is to add a line in your application/config/routes.php file. Such as:
$route['about'] = 'main/about';
This means, a request where the url matches /about will map to main/about
Main being the controller and about being the method within that for example.
See this part of the documentation for a more detailed explaination
https://www.codeigniter.com/userguide3/general/routing.html
Hope this helps
Make sure that you have named the Class for your controller as the controllers file name. Then try to access the page as shown in the code below.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Pages extends CI_Controller {
function about()
{
$data['title'] = 'About us Page';
$this->load->view('about', $data); //about is in views
}
}
?>
The file name should be pages.php in this case.
To access the about page type in this link mysite.com/index.php?/controllerfolder/pages/about.
If you want clean url and remove index.php? edit your htaccess. Use this link to know how to edit your htaccess

Hope this is helpful. Thanks

I am creating a web application in Codeignitor using Laragon as my local server. When I try to "redirect" to a Controller - I get "404 Page Not Found". If I redirect to View - it works. I can access Controllers with other methods such as "Form Open".
Here is my .htaccess file:
RewriteEngine on
RewriteCond $1 !^(index\.php|assets|images|js|css|uploads|favicon.png)
RewriteCond %(REQUEST_FILENAME) !-f
RewriteCond %(REQUEST_FILENAME) !-d
RewriteRule ^(.*)$ index.php/$1 [L]
This is my Controller - for a test I used Redirect to a View "page-login" and a Controller "Private-area". I can access the View, but the Controller sends to 404 Page Not Found.
if($this->form_validation->run()){
$result = $this->login_model->can_login($this->input->post('user_email'), $this->input->post('user_password'));
if($result == ''){
redirect('private_area');
}
else {
$this->session->set_flashdata('message', $result);
redirect('page-login');
FYI I can access Controllers (in this example "Register") using other methods such as Form Open like this:
<?php echo form_open('register/validation'); ?>
Why do I get the 404 error?
Your redirect syntax is incorrect:
the CI function redirect() is structured like this:
redirect($uri = '', $method = 'auto', $code = NULL)
keep in mind to use a relative path like '/my_controller/my_function'
as in this example:
redirect('/login/form/');
you need to autoload/load the URL helper with: $this->load->helper('url');
the form_open() syntax is correct, you need to autoload/load the Form Helper with: $this->load->helper('form');
redirect() function
Does a “header redirect” to the URI specified. If you specify the full site URL that link will be built, but for local links simply providing the URI segments to the controller you want to direct to will create the link. The function will build the URL based on your config file values. (- source)
So, the url must be
redirect("/controller/method/parameters");
Or full url
In your code, Codeigniter will look for the index() method of private_area controller.
Thanks All!
So I think #Don'tPanic nailed it. I thought "Redirect" would point to a Controller - but it points to a Route. So I created a Route in my Routes.php file where
$route['private_area'] = 'private_area';
And everything works. Is this the correct way to do this?
Ie to define Routes in the Routes.php file...then call upon them as required using "Redirect"?
I've created one test.php file in location applications\views\test\test.php with controller in application\controller\Test.php & model in applications\models\Test_model.php.
In my routes.php file, I have added $route['test']='test/view'.
Please note there are some files present already which are working quite fine, one of which is login.php & it has value in routes.php as $route['login']='login/view'. Plus this file does have same model & controller files in likewise location.
When I try to access localhost\test, it gives me 404 error whereas for localhost\login works quite fine.
Can anybody help in routing? I'm new to codeigniter & I could not resolve this issue.
EDIT
htaccess works fine as localhost\login is loading properly along with other few files.
EDIT 2
Test_model.php
<?php
class Test_model extends CI_Model{
public function __construct()
{
$this->load->database();
}
}
?>
test.php
<div>Testing</div>
Test.php
<?php
class Test extends MY_Controller{
public function __construct()
{
parent::__construct();
$this->load->model('test_model');
}
public function view()
{
$this->loadHeader();
$this->load->view('test/test');
$this->loadFooter();
}
}
?>
routes.php
$route['test'] = 'test/view';
EDIT 3
When I try to access localhost\application\controllers\Test.php, it gives me an error that says Class My_Controller not found. However, when I attempt to do it with any other file let's login with with the same location, it gives me the same error.
So I guess, it's able to find the controller because it's giving an error obviously but not able to load anything else.
Is there some sort of config file in which I have to mention every new page I create or something? There has to be something. This is pretty basic & I'm not able to get to the root of it.
EDIT 4
So this is what a problem is. When I copied my test view file to pages folder, it worked. Of course in controller I edited path of the file.
Now the real question is why didn't new folder named test under views work?
Finally, the culprit was this line in routes.php file:
$route['(:any)'] = 'pages/view/$1';
I was adding other route below this so it was getting default behaviour. I put them above this line & it worked like a charm. I never thought this could be the issue.
Line number matters, now.
Create a .htaccess file and paste this code below
DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|images|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php/$1 [L,QSA]
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 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. :)
Ok I have adopted a CodeIgniter Setup,
My route.php in config looks like this:
$route['default_controller'] = "development";
My development.php controller looks like this:
class Development extends Controller
{
function Development() {
parent::Controller();
}
public function Index() {
$this->load->view('index');
}
function show() {
$this->load->view('show');
}
}
When I go to the root folder, in my browser, it does load the index.php view, I want to make a link to show.php which is also in my Views dir. the URL I'm using is eg: my.server/test/codeigniter/ but when I go to my.server/test/codeigniter/show my show.php doesn't load. Am I doing this correctly?
I should mention I've tried public function show() also and it doesn't work, also I have no .htaccess file in the directory
Any advice would help!
Two rules are enough in your .htaccess file:
# check if the requested resource is not an existing file
RewriteCond %{REQUEST_FILENAME} !-f
# rewrite internally to index.php
RewriteRule ^(.*)$ index.php [QSA,L]
Mod_rewrite and AllowOverride All assumed enabled.
Ken Struys comment on your question is correct. The default controller status you give a controller means that controller and the index function will load if you go to
my.server/test.
Other than that, you need to include index.php/controller_name/function_name to get to your controller functions.
Unless that is, you implement some fancy .htaccess url rewriting, which I can't help you with.
You can set it in routes.php as below:
$route['show']='development/show';
