Hello Experts,
i´m really confused on writing a mod rewrite rule for my webpage runing on Apache Webserver. I have never done this befor and don´t know how to start. I only know how to make the .htaccess file and set the rule but don´t know how to write the rule.

i have a php script which need several params the link to a site look like:

index.php?id=1&city=Berlin&country=DE&zip=01234&uk=50&ed=today
or
index.php?id=1&city=Berlin&country=DE&zip=01234&uk=50&ed=tommorrow
or
index.php?id=1&city=Berlin&country=DE&zip=01234&uk=50&ed=20081023&page=3

The arrangement of the params can be different and params can be missing.

for example:
index.php?id=1&country=DE&zip=01234&city=Berlin&uk=50&ed=20081023
or
index.php?id=1&zip=01234&city=Berlin

how to write a rewrite rule that will give the following result?

mypage/Country-Zip-Cityname/20081023/index.html
or
mypage/Country-Zip-Cityname/today/index.html
or
mypage/Country-Zip-Cityname/today/page_1.html

what happens if the country or zip param is not set?

> mypage/Country-Zip-Cityname/20081023/index.html

assuming that you mean the value from the parameter for the literals "Country", "Zip" and so on, what should be the value if the parameter is missing as in
> index.php?id=1&zip=01234&city=Berlin

What happens to the id= parameter

the id=1 is the default param. if you enter the site the id param is not set. If the id param is set it should look like mypage/Country-Zip-Cityname/20081023/1_index.html.

Also when i enter  mypage/Cityname
the url should look like index.php?city=Berlin

is this possible with mod_rewrite

hmm, it's getting more confuse as you last post expects a rewriting which is exactly the oposite of what you describe in the question, I'll give a suggestion for your question!

RewriteCond   %{REQUEST_URI}  !^/*mypage/$
RewriteCond   %{REQUEST_URI}  *index.php
RewriteRule index.php\?id=([^&])&city=([^&])&country=([^&])&zip=([^&])&uk=([^&])&ed=([^&])&page=([^&])   /mypage/$3-$4-$2/&$6/page_$7.html [L]

> The arrangement of the params can be different and params can be missing.
then you have to use a RewriteRule like above for each variant of these arrangements
