Another subdomain question

[eluser]Fatih[/eluser]
Dears,

I have searched forum about multiple domain and subdomain names but I couldn't answer of my these problems.

I want to use one CI and my subdomain names will be input for my database. Please find an example:

Code:

http://mytopic.example.com/item/myitem

In this url, mytopic is a variable in my database which is pointed out to a theme. When item.php controller get this mytopic variable, item application will be run on this specified theme.

How can I solve it?

I solve my problem with below .htaccess modification and want to share with you.

Code:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^([^\.]+)\.exampleyoursite\.com$ [NC]
RewriteCond %1 !^(www|ftp|mail)$ [NC]
RewriteRule ^.*$ http://www.exampleyoursite.com/user/%1 [R,L]

If users linked to http://fatigue.exampleyoursite.com, your "user" controller will be run and show about user profile which name is fatigue: http://www.exampleyoursite.com/user/fatigue

I've been trying to grapple with this problem for the longest time. Did you have to do anything with you DNS server? Or did you do this through .htaccess only?

Jamongkad,

Yes, you must set up wildcard dns for subdomains. You can find some information in this address.

Edit: Also you can find a real sample:
http://fatigue.codeigniter.gen.tr this url is pointed to http://www.codeigniter.gen.tr/user/show/fatigue
