How can I math a regular expression to write an htaccess rule - apache

I want this URL
http://rebateninja.com/index.php?page=home
To be previewed like this via htaccess
http://rebateninja.com/home
I know it is not that hard and I have done that before, but for some reason it is not working now at all. My .htaccess contains the following:
RewriteEngine On
RewriteRule (index.php\?page=)(.*) /$2 [NC,R=301,L]
What I am doing wrong? Perhaps it is related to my Apache version? I have lost my entire morning without success!!! Thanks for your answers.

You can't match against the query string in a RewriteRule, you need to use a RewriteCond with either %{THE_REQUEST} or %{QUERY_STRING} and use a % to backreference groupings:
RewriteCond %{THE_REQUEST} ^(GET|POST|HEAD)\ /index\.php\?page=([^&\ ]+)
RewriteRule /%2? [L,R=301]
That externally redirects the browser so that the URL in the address bar changes. In order to internally rewrite it back you need to do:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.phjp?page=$1 [L]

Try this.
RewriteRule ^index.php\?page=(.*)$ /$1 [NC,R=301,L]

URL Rewriting Using .htaccess for PHP

I want to convert this URL example.com/post.php?id=12345&title=xyz to example.com/12345/xyz.
I am able to do example.com/12345 but I can't get /xyz.
RewriteEngine On
RewriteRule ^post/([a-zA-Z0-9-/]+)$ post.php?id=$1
RewriteRule ^post/([a-zA-Z-0-9-]+)/ post.php?id=$1
With your shown samples, please try following htaccess Rules. Please make sure to clear your browser cache before testing your URLs.
This solution assumes that you are hitting example.com/post.php?id=12345&title=xyz sample url in browser and want to change it to example.com/12345/xyz
##Enabling engine here.
RewriteEngine ON
##Extrenal redirect 301 to mentioned url by OP in question.
RewriteCond %{THE_REQUEST} \s/post\.php\?id=([^&]*)&title=(\S+)\s [NC]
RewriteRule ^ %1/%2? [R=301,L]
##Internal rewrite to post.php with query strings.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]*)/([^/]*)/?$ post.php?id=$1&title=$2 [QSA,L]

Redirection is not working with mod_rewrite in htaccess

I need to redirect few URIs having query string like:
/pages/foo.bar?pageId=123456 to http://some.site/spam/egg/
/pages/foo.bar?pageId=45678 to http://another.site/spaming/egging/
I have this in my htaccess:
RewriteEngine On
RewriteCond %{REQUEST_URI} ^/pages/foo.bar$
RewriteCond %{QUERY_STRING} ^pageId=123456$
RewriteRule ^.*$ http://some.site/spam/egg/ [R=301,L]
RewriteCond %{REQUEST_URI} ^/pages/foo.bar$
RewriteCond %{QUERY_STRING} ^pageId=45678$
RewriteRule ^.*$ http://another.site/spaming/egging/ [R=301,L]
But its not working, showing 404. What am i doing wrong?
You need to move these 2 rules i.e. before all other rules just below RewriteEngine On line as other rules might be overriding this.
(Based on your comments) Your culprit rule is this rule:
RewriteRule . index.php [L]
Which is actually rewriting every request to index.php and changing value of REQUEST_URI variable to /index.php thus causing this condition to fail:
RewriteCond %{REQUEST_URI} ^/pages/foo.bar$
From your example, you get redirected to
http://some.site/spam/egg/?pageId=123456
http://another.site/spaming/egging/?pageId=45678
You can use your browser developer tools to see the redirection (in the Network tab).
Maybe the query strings in the redirected URL lead to a 404? You can add a ? at the end of your redirection to clear the query string:
RewriteCond %{REQUEST_URI} ^/pages/foo.bar$
RewriteCond %{QUERY_STRING} ^pageId=45678$
RewriteRule ^.*$ http://another.site/spaming/egging/? [R=301,L]

Apache RewriteRule fails on question mark

We had a typo when creating URLs, so
/wasserh?hne/wasserhahn-1-2-zoll-dg11040-e+1281
should be redirected to
/wasserhaehne/wasserhahn-1-2-zoll-dg11040-e+1281
the .htaccess starts with
RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.kull-design.com$1 [R,L=301]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.*) index.php [L]
RewriteRule ^eng/deu index.php
and normally sth like this works
Redirect 301 /blog/tag/wasserhaehne-aus-messing/ https://www.kull-design.com/wasserhahn-classic/wasserhahn-13cm-40-593+631
but this fails
RewriteRule /wasserh?hne/wasserhahn-1-2-zoll-dg11040-e+1281 https://www.kull-design.com/wasserhaehne/wasserhahn-1-2-zoll-dg11040-e+1281
I tried to escape the ?, but that doesn't help. I suspect that the part after the ? is seen as query string, so I attempted
RewriteCond %{QUERY_STRING} hne/wasserhahn-1-2-zoll-kurz-dg11040m+1277
RewriteRule ^/wasserh https://www.kull-design.com/wasserhaehne/wasserhahn-1-2-zoll-kurz-dg11040m+1277 [R=301,L]
but that doesn't do the trick. There are similar questions, but they deal with real query strings.
Update:
I tested PanamaJacks solution using htaccess.madewithlove.be. It seems any url starting with wasserh is redirected to the same product. So i tried this instead
https://www.kull-design.com/wasserh?hne/wasserhahn-gebogen-dg110h76870+1295
RewriteEngine On
RewriteCond %{QUERY_STRING} ^hne/wasserhahn-gebogen-dg11010+1295
RewriteRule ^wasserh(.*)$ https://www.kull-design.com/wasserhaehne/wasserhahn-gebogen-dg11010+1295 [R=301,L]
but it doesn't match the condition. Again escaping - or + has no effect.
Update:
Note that you have to put these redirects before the RewriteRule, that sends anything to index.php or it won't work in spite of the rewrite-conditions being correct.
Actually this should work kinda. Give this rule a try and see if it works for you.
RewriteEngine On
RewriteCond %{QUERY_STRING} ^.+$
RewriteRule ^wasserh(.*)$ https://www.kull-design.com/wasserhaehne/wasserhahn-1-2-zoll-kurz-dg11040m+1277? [R=301,L]
Edit:
Then just try matching part of it that is unique to that URL.
RewriteCond %{QUERY_STRING} ^hne(.+)1281$
RewriteRule ^wasserh(.*)$ https://www.kull-design.com/wasserhaehne/wasserhahn-1-2-zoll-kurz-dg11040m+1277? [R=301,L]

flexibility in .htaccess for mod_rewrite rules

i would like to redirect my old php files to new seo friendly ones:
user.php?user=$var1&task=$var2 -> url/$var1/$var2
There are 2 problems. $var2 is not set every time, so i do not know how to deal that and the querystring is always added at the end.
I use the following redirect rule for testing (without $var2)
RewriteCond %{THE_REQUEST} ^(.+)user\.php(.+)$
RewriteCond %{QUERY_STRING} user=([^/]+)$
RewriteRule ^(.+)\.php$ %1 [R]
I get this:
url/$var1/?user=$var1
Second problem is the rewrite rule so that url/$var1 -> user.php?user=$var1
Without it i get a server error.
In the moment i tried this static one for testing, but this is not the only rule so that the Condition is wrong here
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/?$ user.php?user=$1 [L]
How i get the correct results and more flexibility with the variables?
mod_rewrite is not my world in the moment, so i hope you can bring light in the dark.
Thx ruven
1) The way to prevent the query string at the end there is to add a ? at the end of the URL you rewrite to.
RewriteCond %{THE_REQUEST} ^GET\ /user\.php
RewriteCond %{QUERY_STRING} user=([^&=]+)$
RewriteRule ^user\.php %1? [R]
And in case both var1 and var2 are set it would be
RewriteCond %{THE_REQUEST} ^GET\ /user\.php
RewriteCond %{QUERY_STRING} user=([^&=]+)$
RewriteCond %{QUERY_STRING} task=([^&=]+)$
RewriteRule ^user\.php %1/%2? [R]
Combine these (the second one first) and it should redirect as needed
2) Since this is a kind of 'catch all' URL you should put this as the last option in your .htaccess and redirect everything that is not a file or a directory to user.php and then let user.php figure out if the user exists, and if not respond with HTTP 404.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)$ user.php?user=$1 [L]
(I've removed the / at the end as it's not a good idea to have two URLs for the exact same content).

Check URL and stop processing using htaccess

I want to check URL using htaccess. Developer might want run special file - specialfile.php. I use htaccess:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} /specialfile\.php$
RewriteRule .* [L] #don't change adress
RewriteRule ^$ public/index.html [NC,L]
RewriteRule (.*) public/$1 [NC,L]
My idea was: if rewriteCond %{REQUEST_URI} !/specialfile.php$ true than htaccess should use RewriteRule .* [L] - that should mean that specialfile.php will be run and this all. But it doesn't work because it runs next rule: RewriteRule (.*) public/$1 [NC,L].
I think you are using the RewriteCond not correctly. The conditions only affect the next RewriteRule that follows.
Check out the example on the Apache Homepage. Since your 2nd RewriteRule is evalutated, I think your conditions are not correct. To get a litte bit more information about the rewriting, you should increase the log level. This is also documented here.
Your 2nd rule ^$ matches only an empty request btw. That's why it probably does not work as you expect it to.
