How to get variable in query string without using "?"

Question

I'm trying to use GET to capture member IDs in a URL without using the ?name=variable. For instance, instead of using mydomain.com/folder?id=1234 I would like to use mydomain.com/folder/1234 and pick up the id "1234" in the code so I can pass it to another URL.

This page simply redirects by using: <iframe src="http://redirect_domain.com/folder/index.php" />

I have no control over the server I'm redirecting to, but need the variable passed to it. I can append the redirect URL with ?id=1234 ie <iframe src="http://redirect_domain.com/folder/index.php?id=1234" />

Their code will pick up the id by using <?php echo $_GET["id"]; ?>

Thanks for your help.

What you're looking for is called a rewrite rule. You can use rewrite rules in conjunction with a redirect or proxy. — Brad

@FreshPrinceOfSO This question is very specific, and he can't have code to do anything with it if he doesn't know at all how to begin. — Brad

@Brad Then OP is lacking a basic understanding of the problem being solved; which is off-topic. — Kermit

I think you are asking for the rewrite that would take as its input mydomain.com/folder/1234, and redirects it to mydomain.com/folder?id=1234 - did I understand correctly? — Floris

You'll want to use .htaccess for this. Create a file called .htaccess and put it in the same folder mydomain.com is referencing. Put something like the following in there

RewriteEngine On
RewriteRule ^folder/(.*)$ folder?id=$1 [L]

Note: mod_rewrite must be enabled on apache, but it usually is.

Update: I've updated the .htaccess to reflect a local URL since you've made your desired functionality more clear. Using this .htaccess in conjunction with <iframe src="http://redirect_domain.com/folder/index.php?id=<?=$_GET['id']?>" /> should do the trick.

I think there's one too many folder/ in your string... but otherwise this looks a lot like the answer I was about to write. Thanks for saving me the trouble.

I included 2x /folder because that's what OP mentioned.

Floris Over a year ago

RewriteRule ^folder/(.*)$ redirect_domain.com/folder/index.php?id=$1 [L] should be the correct formulation based on the updated question.

Well, the question changed, so now .htaccess is not the solution

@user1322707 - turn on logging of the Apache server to tell you exactly what the rewrite engine is doing; see httpd.apache.org/docs/current/mod/core.html#loglevel . Once you know what your rule is doing (vs what you thought it's doing) it will be easy.

Create a .htaccess file and use something like this

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

I feel the need to write my own answer down. The following two lines in your .htaccess should do exactly what you are asking for:

RewriteEngine On
RewriteRule ^folder/(.*)$ redirect_domain.com/folder/index.php?id=$1 [L]

According to the rewrite rule test site http://martinmelin.se/rewrite-rule-tester/ , when I use an input of folder/1234, it is redirected to redirect_domain.com/folder/index.php?id=1234 which is exactly what you asked for. There is no need for the <iframe... or any actual files in the /folder/ other than the .htaccess ...
