is there any php function that can get the domain prefix user has typed?

[kee2ka4]

Hi everyone,

 

I use the following redirect_to($address) function that I use to redirect a user to a page based on the parameter passed. Here is the code:

 

define('WEBSITE', 'http://domain.com/');

function redirect_to($address)
{
   header('location:'.WEBSITE.$address);
 exit;
}

 

I have a another domain name called http://domain.co.uk/ and hence if a user has come to the site using domain.co.uk then I do not want it to change to domain.com. But whenever the redirect_to function runs it loads http://domain.com since I have definted that in the 'WEBSITE' variable.

 

Is there any function in php that can get the main domain name that the user has typed in the URL. I only need the main domain, no subfolders, so i.e. http://domain.co.uk or http://domain.com, whatever the user has typed in the URL when they visited the site.

 

Thanks

Ket

you can store it in a session

example

<?php
if(empty($_SESSION['domain'])){
$_SESSION['domain'] = "Blah";
}
#then in the page use $_SESSION domain for all your links
?>

sessions start with

<?php session_start();  //more code as advised below// ?>

 

remeber every page got to use session all need the session_start(); on the top line off the php code.

sessions start with <?php session_start();  //more code as advised below// ?>

 

Yes I forgot it but however sessions do not always need that if session autostart is turned to on

Actually if you are  using session autostart than putting in session_start() will cause some funky urls occasional and is doing something unneeded so its would be bad programing practice

 

good practice would be knowing your servers config's and using the language to that config you want.
