How to make a redirect like this

[sphinx]

Hi I had it on my old site but forgot what I put in the index.php file.

 

Basicly, I want something like this:

 

http://site.com/index.php?go=home

 

or:

 

http://site.com/index.php?home

 

Does anyone know what I put in the index.php file to specify link and where it redirects too?

 

Thank you.

everything behind the question mark is called the query string.

 

To get it you use

$_SERVER['QUERY_STRING'];

 

for example:

echo $_SERVER['QUERY_STRING'];

http://localhost/index.php?home

will show 'home'

 

http://localhost/index.php?go=home

will show 'go=home'

 

Using $_GET will give you an array of all the keys and values in the query string:

echo $_GET['go'];

will show 'home'.

yes but it's not a search query, just a link.

thanks, im getting there, i tried this:

 

<?php
$id=5;
$location="index.php?id=go";
header( 'Location:http://www.google.com');
?>

 

if i access my website root, it redirects me too google even without the ?id=go in the link.

[Chris92]

header("location: http://google.com/?id=go");

 

If you want it in variables:

$str = "id=go";
header("location: http://google.com/?". $str );

That still redirects on root, Basicly, when user clicks a link which is:

 

http://mysite.com/?redirect

 

it takes them to another part of the site, that code does:

 

http://www.google.com/?id=go

 

when i access root.

I'm confused.

[sphinx]

this is what i mean:

 

<?php
$link = 'http://www.google.com';
if (@$_GET['id'] == 'go')
header('Location: ' . $link);
?>

 

but i want it to work like:

 

site.com/?go = redirects to google.

 

instead of: site.com/index.php?id=go

[Chris92]

$link = 'google.com';
if( !empty($_SERVER['QUERY_STRING']) && $_SERVER['QUERY_STRING'] == 'go' )
{
    header("location:" . $link);
}
