PHP Redirect with query parameters

Question

Let's say I have the following URL:

http://example.com/index.php?user/1234

What I want the PHP query to do is redirect the user to the following URL:

http://example.com/test/index.php?user/1234

Of course, the URL should not only redirect ?user/1234 but also ?anything/343. I want to leave the url intact and only add the /test/ to it, and leave the part afterwards the same.

How do I accomplish that? All I could find is just general redirection and not specific to URLs. Thanks.

If I understand your question correctly, you need to parse your URL string and add 'test' to the path. The code below should do just that:

// $fullUrl = $_SERVER['REQUEST_SCHEME']."://".$_SERVER[HTTP_HOST].$_SERVER[REQUEST_URI];
$fullUrl = "http://example.com/index.php?user/1234";
// split the url
$url = parse_url($fullUrl);
$url['path'] = "/test" . $url['path'];
// create the new url with test in the path
$newUrl = $url['scheme'] . "://".$url['host'].$url['path']."?".$url['query'];
header("Location:" .$newUrl);

Yes, you understood that correctly. The code isn't working quite correctly however. I get http://example.com/:///test_://example.com/index.phpuser/1234/ as the URL. So it has some wrong ` symbols, it's missing the ?` character and I get the domain name twice.

I forgot the question mark between path and query other than that it works for me.

Weird, I get the following http://example.com/:///test://example.com/index.php?user/1234. So it's some strange stuff with :// and the fact that it doesn't remove the second example.com

Kasia Gogolek Over a year ago

what is the values for your: $_SERVER['REQUEST_SCHEME'] $_SERVER[HTTP_HOST] $_SERVER[REQUEST_URI] ?

Okay, I fixed it. Thank you for your help. I posted my edit in the OP.

I modified Kasia Gogolek's answer so that it works for me. This is the solution to my question:

$fullUrl = $_SERVER[REQUEST_URI];
// split the url
$url = parse_url($fullUrl);
$url['path'] = "/test" . $url['path'];
// create the new url with test in the path
$newUrl = $url['path']."?".$url['query'];
header("Location:" .$newUrl);

You could use PHP header('location: url') as here.

URL being your intended new destination.

I don't know the new destination, it's dependent on the query

Billy Purvis Over a year ago

Could you be more specific? What would be different each time, the test part of the URL?

OldMcDonald Over a year ago

No, test would stay the same. Only the part afterwards should change. So for example, example.com/index.php?whatever should become example.com/test/index.php?whatever

Billy Purvis Over a year ago

You'd capture that, and append it to the new built URL. Kasia Gogolek's answer explains more.

This used to be troublesome, but works for me now:

header("Location: /test/index.php?" .$_SERVER['QUERY_STRING']);

Should be a simple header redirect

header("Location:http://example.com/test/index.php?user/1234");

If the relocation is dependant on the query, then you need to build the location url.

For example, if you 2 variables on your page you want to use, 1 that is $page and one that is $id, you would do it like this.

 $id = 123;
 $page = 'user';

 header("Location:http://example.com/test/index.php?".$page."/".$id);

This would produce a url of

http://example.com/test/index.php?user/123

Yes, but what would I do if the URL doesn't have "?user/1234" but instead "?help/343"

S_R Over a year ago

Then you would change it to header("Location:http://example.com/test/index.php?help/343");

@OldMcDonald please be more specific about what you are trying to achieve

Twinfriends Over a year ago

@OldMcDonald don't write it static, write it dynamic by putting your URL into a variable. Btw that URL format seems to be really weird...

OldMcDonald Over a year ago

I made my post clearer now. I want to add the /test/ part to the URL and leave everything afterwards the same.
