Redirect to a new domain based on GET parameters

I already used 301 redirect many times, but this time I'm facing a new problem. I have an old website on Joomla and all the pages on the website are loaded by the same index.php file. Example :

URL of a page           : http://domain.com/index.php?option=com_content&view=section&id=4&Itemid=54
URL of a different page : http://domain.com/index.php?option=com_content&view=section&id=1&Itemid=55

How can I redirect each of these pages to other pages?

By example, I'd like that the page http://domain.com/index.php?option=com_content&view=section&id=4&Itemid=54 redirect to http://newdomain.com/location/

I need to make a 301 redirect based on GET parameters but I can't figure how.

Your help would be very appreciated !

If possible to do this in the htaccess file?

You can use rules like this your DOCUMENT_ROOT/.htaccess file:

RewriteEngine On

RewriteCond %{QUERY_STRING} ^option=com_content&view=section&id=4&Itemid=54$
RewriteRule ^(index\.php)?$ http://newdomain.com/location/? [L,NC,R=302]

Make sure these rules are placed before any other rules.

use a simple switch

switch($_GET['id']){
    case 1:   $myPage = "http://newdomain.com/location/"; break;
    case 4:   $myPage = "http://othernewdomain.com/location/"; break;
    default:  $myPage = "http://google.com"; break;
}
header("Location: {$myPage}");

of course you could easy add more parameters and switch them... like

if($_GET['id'] == 1 && $_GET['item'] == 55 ){
    $goto = 1;
}
switch($goto){ ... }

htaccess would be some like

RewriteEngine On
Redirect 301 /index.php?option=com_content&view=section&id=4&Itemid=54 http://www.domain.com/

The parameters that are sent through a GET are received as a structure like this:

array(n):
    name_1 = 'value1',
    name_2 = 'value2',
    ...
    name_n = 'valueN',

And you can access them through the $_GET variable, where every key equals to the name of the parameter, e.g. to access the value bound to the parameter with the name 'foo', you can:

$bar = $_GET['foo'];

On your PHP script. So you can just make a simple flow controller, or a switch that effectively detects the parameters sent through the GET and redirects to the URL you're looking for:

final class Redirect {

    public static function toUrl($url, $parameters = array(), $statusCode = 303) {
        header('Location: ' . $url . http_build_query($parameters), true, $statusCode);
    }

}

$parameter = $_GET['key'];

switch ($parameter) {
    case '<the specific parameter>':
        Redirect::toUrl('http://example.com/');
        break;
    case '<other case>':
        ...
}

The $parameters argument is optional and you can use it to send some other data to the new URL via GET too, and you can also control the status code sent via the optional $statusCode parameter.

The string after the ? in the URL is called the query string. In PHP, it's contained in the QUERY_STRING environment variable. So, you can do what you want to do using if statements in your index.php script to test the contents of the query string, like so:

if($_SERVER['QUERY_STRING']=="option=com_content&view=section&id=4&Itemid=54") { header("Location: http://newdomain.com/location/"); }

Using htaccess I believe you can do that.

This should work :

  RewriteEngine On
  RewriteCond %{HTTP_HOST} ^olddomain.com$ [OR]
  RewriteCond %{HTTP_HOST} ^www.olddomain.com$
  RewriteRule (.*)$ http://www.newdomain.com/$1 [R=301,L]
