Codeigniter subdomain routing

Question

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:

1. Creating an A record pointing to my server's ip address.
2. 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 :(

do you have htaccess to remove index.php? – Acrodrome

I do yes. Should this make a difference? – Use

Just edited the OP with my htaccess file if it helps. – Use

Still can't get this working, so started a bounty. You CodeIgniter gurus should be able to earn an easy +50 here ;) – Use

Answer 1

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]

I have a question for you - does notedu.mp/blog and notedu.mp/blog/latest also show your blog? – Whitby

Answer 2

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.

Thanks for your answer but I still have the same problem. blog.notedu.mp triggers the function successfully, but blog.notedu.mp/latest throws an apache 404 page (not a CodeIgniter one). Any ideas? – Use

Answer 3

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

Thanks for your answer. I have the following rule within my sites-enabled file for my domain but still 404. # Give .htaccess full override permissions <Directory /> AllowOverride AuthConfig FileInfo Indexes Limit Options=All,MultiViews </Directory> – Use

Answer 4

$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

Thanks for your answer. This is actually what I have in my route - I forgot to update this part of the code since my last edit. I added $route['(:any)'] = "blog/latest"; as a test also, but I still get a 404. Any ideas? – Use

Can you echo out $_SERVER['HTTP_HOST'] to verify it's what you expect (blog.notedu.mp)? Also, can you check error_log and access_log? – Despite
