Codeigniter subdomain routing - php

I'm trying to setup a blog script on a website running on the CodeIgniter framework. I want do this without making any major code changes to my existing website's code. I figured that creating a sub domain pointing to another Controller would be the cleanest method of doing this.
The steps that I took to setup my new Blog controller involved:
Creating an A record pointing to my server's ip address.
Adding new rules to CodeIgniter's routes.php file.
Here is what I came up with:
switch ($_SERVER['HTTP_HOST']) {
case 'blog.notedu.mp':
$route['default_controller'] = "blog";
$route['latest'] = "blog/latest";
break;
default:
$route['default_controller'] = "main";
break;
}
This should point blog.notedu.mp and blog.notedu.mp/latest to my blog controller.
Now here is the problem...
Accessing blog.notedu.mp or blog.notedu.mp/index.php/blog/latest works fine, however accessing blog.notedu.mp/latest takes me to a 404 page for some reason...
My .htaccess file looks like this (the default for removing index.php from the url):
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
And my Blog controller contains the following code:
class Blog extends CI_Controller {
public function _remap($method){
echo "_remap function called.\n";
echo "The method called was: ".$method;
}
public function index()
{
$this->load->helper('url');
$this->load->helper('../../global/helpers/base');
$this->load->view('blog');
}
public function latest(){
echo "latest working";
}
}
What am I missing out on or doing wrong here? I've been searching for a solution to this problem for days :(

After 4 days of trial and error, I've finally fixed this issue!
Turns out it was a .htaccess problem and the following rules fixed it:
RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
Thanks to everyone that read or answered this question.

Does blog.domain.co/blog/latest also show a 404?
maybe you could also take a look at the _remap() function for your default controller.
http://ellislab.com/codeigniter/user-guide/general/controllers.html#default
Basically, CodeIgniter uses the second segment of the URI to determine which function in the controller gets called. You to override this behavior through the use of the _remap() function.
Straight from the user guide,
If your controller contains a function named _remap(), it will always
get called regardless of what your URI contains. It overrides the
normal behavior in which the URI determines which function is called,
allowing you to define your own function routing rules.
public function _remap($method)
{
if ($method == 'some_method')
{
$this->$method();
}
else
{
$this->default_method();
}
}
Hope this helps.

have a "AllowOverride All" in the configuration file of the subdomain in apache?
without it "blog.notedu.mp/index.php/blog/latest" work perfectly, but "blog.notedu.mp/latest" no

$route['latest'] = "index";
means that the URL http://blog.example.com/latest will look for an index() method in an index controller.
You want
$route['latest'] = "blog/latest";
Codeigniter user guide has a clear explanation about routes here

Redirect to Controller results 404 Page Not Found

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"?

404 error in new page created in codeigniter

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]

URI ROUTING in CodeIgnitor_2.1.3 throwing "Not Found" error

I have installed CodeIgniter_2.1.3 and running in
Windows 7
Wamp Server 2.1
PHP 5.3.5
Apache 2.2.17
In \applicationconfig\routes.php, I created
$route['default_controller'] = "welcome";
$route['404_override'] = '';
$route['products/catlog'] = "welcome/getOneMethod";
And in \application\controllers\welcome.php, I created a method
public function index()
{
$this->load->view('welcome_message');
}
public function getOneMethod()
{
echo "hi im in newMethod";
}
http://localhost/CodeIgniter_2.1.3/products/catlog
Now I expect on running this url above on browser to give me the page
hi im in newMethod
But instead i'm getting the error message.
Not Found
The requested URL /CodeIgniter_2.1.3/products/catlog was not found on
this server.
What should i do to make it work correctly?
Doo you visit codeigniter documentation website,You can get help from this url how to create static pages
http://ellislab.com/codeigniter/user-guide/tutorial/static_pages.html
For the given url routes and controller.
you will need to use:
http://localhost/CodeIgniter_2.1.3/index.php/products/catlog/
The index.php part in the url can be removed using htaccess rewrite rule.
In the /codeigniter2.1.3/ folder create an .htaccess file and put the following rule:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /CodeIgniter_2.1.3/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /CodeIgniter_2.1.3/index.php [L]
</IfModule>
Note: This might not be the best way to do it.
EDIT:
Make sure the controller is exactly as bellow,
class Welcome extends CI_Controller {
public function index() {
$this->load->view('welcome_message');
}
public function getOneMethod() {
echo "hi im in newMethod";
}
}
and the routes are as bellow:
$route['default_controller'] = "welcome";
$route['404_override'] = '';
$route['products/catlog'] = "welcome/getOneMethod";
For the time being remove the htacces, and make it work with index.php in url.
ie:
http://localhost/CodeIgniter_2.1.3/index.php/products/catlog/
Note: since you are able to see the welcome message, there is no problem with your installation or server. there is probably some syntax error. so i recommend you copy paste the above code, as i have checked them and they are working.

codeigniter redirect from a view

I am building a site entirely on codeigniter .I have set my default controller as cuff.
so whenever users type the domain name it takes the control to that controller.
class Cuff extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper('url');
}
public function index()
{
$this->load->view('index');
}
public function navigate()
{
echo "test";
exit;
}
}
In my index view I want an anchor to navigate to a function in my default controller .
so when I write
our collection , it says page not found .
I have even set the base url like this
$config['base_url'] = "http://".$_SERVER['HTTP_HOST'];
$config['base_url'] .= preg_replace('#/+$#','',dirname($_SERVER['SCRIPT_NAME'])).'/';
Cant seem to figure out the issue.
You missed the controller name
our collection
Set $config['base_url'] ='';
In your .htaccess file:
RewriteEngine on
RewriteCond $1 !^(index\.php|images|js|css|favicon|robots\.txt)
RewriteRule ^(.*)$ /index.php?/$1 [L]
Make sure your controller is in controller's folder (not any subfolder) and is properly named cuff.php
Try navigating to http://yoursite/cuff/navigate
If you still see errors try rewriting the last line in .htaccess to:
RewriteRule ^(.*)$ /index.php/$1 [L]
(without question mark).
Please tell if that helps!
EDIT: and your links better all be in this form:
Link
The problem is in your routing.
Edit your routes.php (located in the folder ../application/config/) and add the code below:
$route['navigate'] = "Cuff/navigate";
For more information regarding Codeingiter URI Routing:
http://codeigniter.com/user_guide/general/routing.html
Hope this helped you.
Simply you use
"<?php echo site_url();?>/cuff/navigate">our collection</a>

CodeIgniter Views

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';
