激活modrewrite后，如何处理PHP中的GET-Parameter？

Question

I've a little problem. I use modrewrite to load language-content dynamically into webpage...

example:

www.mydomain.xyz/en (the english version) www.mydomain.xyz/fr (the french version) ...

My .htaccess:

 RewriteRule ^en$ index.html?lang=en

But:

www.mydomain.xyz/en?foo=bar

and

<?php
 if(isset($_GET["foo"])) {
   echo "Yeah! There is some stuff!";
 }
 ?>

doesn't work... the GET-Parameter is ignored. What I have to do?

• it works, with www.meinedomain.xyz/en.html?foo=bar but I don't want to display any Extensions.

Answer 1

Use QSA flag:

RewriteRule ^en$ index.html?lang=en [L,QSA]

To make this work for en and fr use this:

RewriteRule ^(en|fr)/?$ index.html?lang=$1 [L,QSA]

• QSA (Query String Append) flag preserves existing query parameters while adding a new one.

Answer 2

Simply add [QSA] to your rewrite rule:

RewriteRule ^en$ index.html?lang=en [QSA];

Answer 3

You need the [QSA] instruction right after your rewrite rule

http://httpd.apache.org/docs/current/mod/mod_rewrite.html

QSA is "query string append" and preserves query strings on rewrite

I'd also recomment using (/|$) instead of just $, or calling yourdomain.com/ensomefile.php would also result in rewriting

RewriteRule ^en(/|$) index.html?lang=en [QSA]
