we have a site which developed in CodeIgniter. And also we have the subdomain.
www.mmm.com
www.admin.mmm.com
Now we want to redirect URL to the subdomain.
ex: mmm.com/result/admin/login : this URL will be open by sub domain (admin.mmm.com) .
How can we do it?
分享 You are looking for
redirect($uri = '', $method = 'auto', $code = NULL)
In your case you would do the following in the controller result at the function admin. In that function you should have a code checking if the parameter login is given as the first parameter. Add the following in that piece of code:
redirect('admin.mmm.com');
Explanation from codeigniter documentation (https://codeigniter.com/userguide3/helpers/url_helper.html#redirect)
redirect($uri = '', $method = 'auto', $code = NULL)
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.
The optional second parameter allows you to force a particular redirection method. The available methods are auto, location and refresh, with location being faster but less reliable on IIS servers. The default is auto, which will attempt to intelligently choose the method based on the server environment.
The optional third parameter allows you to send a specific HTTP Response Code - this could be used for example to create 301 redirects for search engine purposes. The default Response Code is 302. The third parameter is only available with location redirects, and not refresh
