I am trying to rewrite URL1 to URL2. Can anybody help?
URL1:
http://www.localhost.de/stellenangebote/ort/hannover/200
URL2:
http://www.localhost.de/path/to/my/script.php?location=hannover&radius=200
Apache uses basic regexes for rewriting so you can use multiple capture groups "()" and reference them using $1 for the contents of the first capture group, $2 for the second and so on. In your case the following should work:
RewriteEngine On
RewriteRule ^stellenangebote/ort/([a-z]+)/([0-9]+) /path/to/my/script.php?location=$1&radius=$2

I imagine this has to be a common scenario but I'm struggling to describe it sufficiently well or to find a working answer!
Essentially I want to make hundreds of URLS that include unique reference codes but that are easy to type in the form example.com/aabbcc, which will be intercepted and all delivered to a PHP script for validating that code, located somewhere like example.com/script.php.
I need the subdirectory part of the URL (aabbcc, in this example) to become a GET parameter for that script, so a URL like the one above would be sent to example.com/script.php?id=aabbcc, while hiding this more complicated URL from the user.
I can see from other .htaccess examples that this must be possible, but I can't find one doing this.
Is there a .htaccess solution for it? Is there something else even more basic? Your help is appreciated in steering me.
If your "unique reference codes" consist of 6 lowercase letters, as in your example then you can do something like the following in your root .htaccess file using mod_rewrite:
RewriteEngine
# Internally rewrite "/abcdef" to "script.php?id=abcdef"
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^[a-z]{6}$ script.php?id=$0 [L]
If you don't need direct access to any subdirectories off the root that also happen to match a "unique reference code" then you can remove the preceding condition (RewriteCond directive). With the condition in place then you naturally can't access any "unique access codes" that happen to also match the name of a subdirectory.
$0 is a backreference to the entire URL-path that the RewriteRule pattern (first argument) matches against.

I am migrating an ASP web site into WordPress. Currently, I am fixing the 404 errors, from the old website to the new but I have find a URL that looks like the following
http://www.mysite.com/www.customer-web-site.com
and I like to redirect this domain to
http://www.customer-web-site.com
currently I have use the following rewrite rule, but with no luck:
RewriteRule ^(www\.([^\.]*)\.([a-z]{2,3})) http://$1 [R=301,L]
but this, redirect me to
http://index.php/
Can somebody help me ?
Kind regards
And what about $1 in the rewrite rule? Does changing it to $0 fixes this?
$1 to $9 provide access to the grouped parts (in parentheses) of the
pattern, from the RewriteRule which is subject to the current set of
RewriteCond conditions. $0 provides access to the whole string matched
by that pattern.

I want to rewrite a URL like:
http://domainname.com/all-studio-methods
To:
http://domainname.com/review.php?id=25&cas=all-studio-methods
My .htaccess file currently looks like the following:
Options +FollowSymlinks
RewriteEngine On
RewriteRule ^([^/\.]*)$ review.php?id=$1&cas=$2 [L]
But it is not working properly. What am I doing wrong?
As noted in the comments, you have this rule:
RewriteRule ^([^/\.]*)$ review.php?id=$1&cas=$2 [L]
The $1 and $2 are backreferences that are replaced with matched groupings in your reqular expression, ^([^/\.]*)$ which only has 1 grouping, the entire match. So $2 will always be blank since you don't have another grouping. This also means that $1 will be the entire match (e.g. all-studio-methods) and you're going to get a URI like this:
review.php?id=all-studio-methods&cas=
Which is obvioiusly not what you want. The comments ask where the id=25 comes from. It's not coming from the URI, /all-studio-methods. So in order to rewrite to id=25, it's got to be in the URI somewhere, for example:
http://domainname.com/25-all-studio-methods
Then you'd have a rule like:
RewriteRule ^([0-9]+)-([^/\.]*)$ review.php?id=$1&cas=$2 [L]
If you really don't want the 25- in the URI, you'll need to rewrite the php code in review.php so that it doesn't take an id. It would need to fetch the ID internally from the database given a cas.
Or, you could create a rewrite map in order to map cas to an id. It's going to be pretty much the same thing, you're writting code to do it in either case.
I am working on a site which will have two levels the URL reaches
My objective is to have clean URL's like this...
http://domain.com/username/dosomething
My ugly URL's currently look like this...
http://domain.com/index.php?page=username&command=dosomething
My attempt was this
RewriteEngine On
RewriteRule ^([a-zA-Z0-9]+)$ index.php?page=$1&command=$2
RewriteRule ^([a-zA-Z0-9]+)/$1/$2 index.php?page=$1&command=$2
You're not using your backreferences correctly in the first part. Backreferences are parenthesised expressions that will then get filled into $1, $2 et al. in the second part of the rule. e.g.:
RewriteRule ^([^/]+)/([^/]+)$ /index.php?page=$1&command=$2
These parenthesized expressions match one or more non-/ characters and fill them into $1 and $2 respectively.
Your references are just referencing your entire URL so what you are telling it to give you is
index.php?page={entire URL}&command={null}
You need to setup the URL and only use parenthesis around the variables page and command. So
^domain.com/([username]+)/(dosomething)
then rewrite with:
http://domain.com/index.php?page=$1&command=$2
provided that your page and command variables are username and dosomething respectively
I wanted to set .htaccess to rewrite:
example.com/bla/info/
to
example.com/info/index.php?q=bla
example.com/bla/info/txt/
to
example.com/info/index.php?q=bla&t=txt
I wanted the browser still to display:
example.com/bla/info/txt/
I didn't want rewrite in the level 2 rewrites, like:
example.com/bla/xxx/
or
example.com/ccc/zzz/aaa/
but
example.com/silly/info/
would work as well as
example.com/strange/info/mytxt/
Did this make sense?
Any help?
If you start your pattern with ^ and end it with $, the rule will only apply if the whole string matches.
RewriteRule ^/bla/info/$ /info/index.php?q=bla
RewriteRule ^/bla/info/txt/$ /info/index.php?q=bla&t=txt
If you use do not use the [R] option, the URL shown in the browser will be whatever the user entered.
Are you trying to make this general-purpose? If so, you can use regex-type matching and variable substitution. To make 'bla' match any string up to the next slash (/), use
([^/]+)
in your pattern and reference it with $1 in your substitution.
RewriteRule ^/([^/]+)/info/$ /info/index.php?q=$1
RewriteRule ^/([^/]+)/info/([^/]+)/$ /info/index.php?q=$1&t=$2
I recommend the Apache web pages about mod_rewrite for more information.
[Edit. Fixed the rules to not include the host name in the pattern, as the original poster figured out.]

you got me in the right track.
i ended up with something like this:
RewriteRule ^([^/\.]+)/info/?$ example/info/index.php?q=$1 [L]
thanks a lot
