Domain and Subdomain sharing the same CI files

[eluser]MEM[/eluser]
Please I need your help:

Issue:


I have the following domain:
http://www.mysite.com

I want to have the following subdomain:
http://admin.mysite.com

They both should share the same 'application' and 'system' folders (they are one level up on the host directory).

www
- www
- admin
private
- application
- system


When the user makes http://admin.mysite.com (a default login controller should be called).
When the user makes http://www.mysite.com (a default homepage controller should be called).

In this scenario, what shoud we put on the application/config.php file?
$config['base_url'] = "http://whats.should.I.put.here"; ?

[UPDATE]
Ok. I realise that is something to do with the router file but, the examples seem to be related with first segment of the URI, second segment of the URI...

But I believe:

http://admin.mysite.com is not on the first segment so, something like this:
$route['admin'] = 'admin/login/' or something, will never work.

I just need a push to be on the right track please...
[/UPDADE]

Please I'm stuck here...

You can't really do this without LOTS of hacking. I would recommend you do something like:

config.php

Code:

$config['base_url']  = 'http://'.$_SERVER['HTTP_HOST'].'/';

.htaccess

Code:

RewriteCond %{HTTP_HOST} ^admin.mysite.com [NC]
RewriteRule ^(.*)$ http://www.mysite.com/admin/$1 [L]

That means if you go on admin.mysite.com it will redirect anything after the / to the admin controller. It also means your URL's will continue to work inside the admin section as you are telling CodeIgniter to use whatever HTTP_HOST it is being accessed under, and we already know that to be admin.mysite.com.

Let me know how it goes!

Thanks a lot for your reply.

.htaccess

Code:

RewriteCond %{HTTP_HOST} ^admin.mysite.com [NC]
RewriteRule ^(.*)$ http://www.mysite.com/admin/$1 [L]

That means if you go on admin.mysite.com it will redirect anything after the / to the admin controller.[/quote]

Ok. But I suppose I will not have an admin controller. I will have an admin folder inside my application/controller/ called admin, and inside that folder, I would have my controllers.

For example:
Let's say I have a public product list method on my products controller, the correspondent URI should be something like this:
http://www.mysite.com/products/list

And it will point to: /private/application/controller/products.php

Let's say I have a private product insert method on my admin products controller, the correspondent URI should look like this:
http://admin.mysite.com/admin/products/insert

It will point to /private/application/controller/admin/products.php


Does your solution still applies here?
And more important...
If it was you, would you do something like this? Would you use a sub-domain like this, or do you believe that, since we are sharing so many resources between domain and subdomain, the subdomain gets a little bit "extra" on this scenario?

Phil Sturgeon, I thank you for your reply. After a while however, I realise that this was not a big thing to do. Since I'm CI newbie, I will stay with the admin folder solution for now.


Kind Regards and sorry for any inconvenience,

Check out some soultions for getting admin folder structures working.

This method would work find if you follow the sub-directory route. Instead of a sub-directory you would have a sub-domain, which would be mapped to the sub0directory... if that makes sense. :-)
