How to store URL param in htaccess variable - .htaccess

All my URLs can be appended with ?lang=xx but I don't want to rewrite all my htaccess rules, so I would like to catch this parameter and attach when available.
I've tried to save the param to variable MYLANG as follows, but doesn't work:
SetEnv MYLANG %{QUERY_STRING} ^lang=([a-zA-Z]{2})$
This is another attempt that didn't work:
RewriteCond %{QUERY_STRING} ^lang=([a-zA-Z]{2})$
SetEnv MYLANG %1
And another attempt:
RewriteCond %{QUERY_STRING} ^lang=([a-zA-Z]{2})$
RewriteRule ^ - [env=MYLANG:%1]
I can then use the captured variable in the rules:
RewriteRule ^(.*).html$ /?name=$1&lang=%{ENV:MYLANG} [NC,L]
Or
RewriteRule ^(.*).html$ /?name=$1 [NC,L,E=MYLANG]

I never used it, but it seems to me that's it:
RewriteCond %{QUERY_STRING} ^lang=([a-zA-Z]{2})$
RewriteRule ^ - [E=MYLANG:%1]
RewriteRule ^(.*).html$ /?name=$1&lang=%{ENV:MYLANG} [NC,L]

Nice idea. Your third attempt:
RewriteCond %{QUERY_STRING} ^lang=([a-zA-Z]{2})$
RewriteRule ^ - [env=MYLANG:%1]
Should work fine.

htaccess rewrite url with a parameter that equals 0

I would like to change
detail.php?cid=$category&ccid=$category2&cccid=$category3&fid=$id&ftitle=$titleseo
to
detail/$category/$category2/$category3/$id/$titleseo
But in case one of the parameters equals 0, the parameter should not be visible.
So in case $category=0, the url should become:
detail/$category2/$category3/$id/$titleseo
In case $category2=0, the url should become:
detail/$category/$category3/$id/$titleseo
Is this possible with a rewrite rule in htaccess and if yes how should this look like?
You could use this considering /$category/$category2/$category3/ have given names /$id/$titleseo are fixed :
RewriteEngine On
RewriteBase /
RewriteRule ^detail/(\$category)?/?(\$category2)?/?(\$category3)?/?(\$id)/(\$titleseo)$ - [E=PASS:cid=$1&ccid=$2&cccid=$3&fid=$4&ftitle=$5]
RewriteCond %{ENV:PASS} (.*)(&)[a-z]+=&(.*)$|[a-z]+=&(.*)$
RewriteRule ^ details.php?%1%2%3%4 [L]
RewriteCond %{QUERY_STRING} (.*)(&)[a-z]+=&(.*)$|[a-z]+=&(.*)$
RewriteRule ^ details.php?%1%2%3%4 [L]
RewriteCond %{ENV:PASS} ^(.+)$
RewriteRule ^ details.php?%1 [L]
In general use this :
RewriteEngine On
RewriteBase /
RewriteRule ^detail/([^/]+)?/?([^/]+)?/?([^/]+)?/?(\$id)/(\$titleseo)$ - [E=PASS:cid=$1&ccid=$2&cccid=$3&fid=$4&ftitle=$5]
RewriteCond %{ENV:PASS} (.*)(&)[a-z]+=&(.*)$|[a-z]+=&(.*)$
RewriteRule ^ details.php?%1%2%3%4 [L]
RewriteCond %{QUERY_STRING} (.*)(&)[a-z]+=&(.*)$|[a-z]+=&(.*)$
RewriteRule ^ details.php?%1%2%3%4 [L]
RewriteCond %{ENV:PASS} ^(.+)$
RewriteRule ^ details.php?%1 [L]
The rules above , first make and environment by capturing any request start with details and ended with /$id/$titleseo then check that ENV values to see which one has/hasn't a value and finally redirect it accordingly.
Both rules work in case of three levels of categories if you need more you could edit the rules like this :
Add this ([^/]+)?/? after RewriteRule ^detail/ then [E=PASS:cid=$1&ccid=$2&cccid=$3&ccccid=$4&fid=$5&ftitle=$6] at the end , you could compare to see the difrenec between this and previous one to get a criteria , and finally add %5 to /details.php?%1%2%3%4 [L] like this /details.php?%1%2%3%4%5 [L] and so on .
Did not get the code from Mohammed to work so far, but used
RewriteRule ^detail/?([0-9a-zA-Z]+)?/?([0-9a-zA-Z]+)?/?([0-9a-zA-Z]+)?/([0-9a-zA-Z]+)/([0-9a-zA-Z]+) detail.php?cid=$1&ccid=$2&cccid=$3&fid=$4&&ftitle=$5

htaccess one OR two parameters

I want a URL like this:
www.mywebsite.com/user
So I do:
RewriteRule ^([a-zA-Z0-9_/-]+)$ profile.php?user=$1
it is working.
but SOMETIMES I need a secound parameter, like:
www.mywebsite.com/user/22 = user?id=22
or I need a secound parameter like this:
www.mywebsite.com/user/images = user?pg=images
notice that I can have an user/id or user/pg for different actions.
Any ideas how can I do this?
You can have 3 rules like this:
Options -MultiViews
RewriteEngine On
# skip all files and directories from rewrite rules below
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
# to handle /user/22
RewriteRule ^user/(\d+)/?$ user.php?id=$1 [NC,L,QSA]
# to handle /user/images
RewriteRule ^user/(\w+)/?$ user.php?pg=$1 [NC,L,QSA]
# existing rule
RewriteRule ^([\w-]+)/?$ profile.php?user=$1 [L,QSA]
It's very easy:
RewriteRule ^user/([0-9]+)$ index.php?user=$1
RewriteRule ^user/([a-zA-Z0-9_/-]+)$ index.php?pg=$1

Cut off parameter from redirect in htaccess

This silent redirect in htaccess:
RewriteCond %{QUERY_STRING} ^pic_id=(\d+)$ [NC]
RewriteRule ^album_showpage\.php$ /gallery/image_page.php?image_id=%1 [L]
redirect a url that looks like:
example.com/album_showpage.php?pic_id=1906
to:
example.com/gallery/image_page.php?image_id=1906
that works great. But when the URL has a parameter like:
album_showpage.php?pic_id=1906&mode=prev
or
album_showpage.php?pic_id=1906&mode=next
the redirect wont work.
Question: How to cut of any parameter after pic_id=1906
thank you
You need match against the rest of the query string.
RewriteCond %{QUERY_STRING} ^pic_id=(\d+)(&.*)?$ [NC]
RewriteRule ^album_showpage\.php$ /gallery/image_page.php?image_id=%1%2 [L]
If you don't want the mode=prev stuff to be included in the rule's target, then you can simply remove the $ instead of attempting to match against it:
RewriteCond %{QUERY_STRING} ^pic_id=(\d+) [NC]
RewriteRule ^album_showpage\.php$ /gallery/image_page.php?image_id=%1 [L]

Htaccess rewriterule and special characters '&'

I am trying to make some really simple redirection from an old to a new website. But all my redirection with the character '&' dont work.
For exemple:
RewriteRule ^-Nos-equipes-$ /-Associes-Collaborateurs-?lang=fr [R=301,L]
work fine, but:
RewriteRule ^-Contact-?&lang=en$ /-Nous-contacter-?lang=en [R=301,L]
Dont work.
I am sure its easy, but i dont find anyway to make it work. I have try flag [NE] , or write [&]...
Thanks. Casp.
EDIT:
I now use the solution anubhava who works;
but not totaly cause my problem is more complexe;
In fact i got some url with param:
?&lang=en, ?&lang=fr, and ?lang=en
So i have had other query string like that:
# Redirection from the old site #--------------------------------------
RewriteCond %{QUERY_STRING} (^|&)lang=fr(&|$)
RewriteCond %{QUERY_STRING} (^|&)lang=en(&|$)
RewriteCond %{QUERY_STRING} ^lang=en(&|$)
This work still great; except in 2 cases:
the first one:
trying to make this redirection (stay on same url but juste modify the param)
RewriteRule ^the_url?&lang=en$ /the_url?lang=en [R=301]
who make an redirection error.
And second case when i have to rewrite the same url but with different param:
RewriteRule ^the_url$ /other_url?lang=fr [R=301]
RewriteRule ^the_url?&lang=en$ /other_url?lang=en [R=301]
RewriteRule ^the_url?&lang=fr$ /other_url?lang=fr [R=301,L]
It works but only with the first one insruction.
(i dont put the flag L, cause i got a long list of rewrite; i think i can put the condition at the beginning and not rewrite them each-time)
:::::::::::::::::::::::
Exemple of real url that i am trying to redirect who cause trouble
www.mywebsite/-Avocats-a-la-Cour- to--> www.mywebsite/?lang=fr
www.mywebsite/-Avocats-a-la-Cour-?&lang=en to--> www.mywebsite/?lang=en
www.mywebsite/Marque-francaise?&lang=fr to--> www.mywebsite//Marque-francaise?lang=fr
www.mywebsite/French-Trademarks?&lang=en to--> www.mywebsite//French-Trademarks?lang=en
www.mywebsite/-Contact-?&lang=en to--> www.mywebsite/-Nous-contacter-?lang=en
www.mywebsite/-Contact-?&lang=fr to--> www.mywebsite/-Nous-contacter-?lang=fr
www.mywebsite/person-780?lang=en to--> www.mywebsite/personel?lang=en
You cannot match QUERY_STRING in RewriteRule. You can use:
RewriteCond %{QUERY_STRING} (^|&)lang=en(&|$)
RewriteRule ^-?Contact-?$ /-Nous-contacter- [R=302,NC,L]
QUERY_STRING is automatically carried over to target URI.
EDIT: Based on your edited question you can have these rules:
# www.mywebsite/-Avocats-a-la-Cour- to--> www.mywebsite/?lang=fr
RewriteCond %{THE_REQUEST} \s/+(-Avocats-a-la-Cour-)\s [NC]
RewriteRule ^ /?lang=fr [R=302,L,NE]
# www.mywebsite/-Avocats-a-la-Cour-?&lang=en to--> www.mywebsite/?lang=en
RewriteCond %{THE_REQUEST} \s/+(-Avocats-a-la-Cour-)\?&?(lang=en)\s [NC]
RewriteRule ^ /?%2 [R=302,L,NE]
# www.mywebsite/Marque-francaise?&lang=fr to--> www.mywebsite/Marque-francaise?lang=fr
# www.mywebsite/French-Trademarks?&lang=en to--> www.mywebsite/French-Trademarks?lang=en
RewriteCond %{THE_REQUEST} \s/+(Marque-francaise|French-Trademarks)\?&(lang=(?:en|fr))\s [NC]
RewriteRule ^ /%1?%2 [R=302,L,NE]
# www.mywebsite/-Contact-?&lang=en to--> www.mywebsite/-Nous-contacter-?lang=en
# www.mywebsite/-Contact-?&lang=fr to--> www.mywebsite/-Nous-contacter-?lang=fr
RewriteCond %{THE_REQUEST} \s/+(-Contact-)\?&?(lang=(?:en|fr))\s [NC]
RewriteRule ^ /-Nous-contacter-?%2 [R=302,L,NE]
# www.mywebsite/person-780?lang=en to--> www.mywebsite/personel?lang=en
RewriteCond %{THE_REQUEST} \s/+(person-780)\?&?(lang=(?:en|fr))\s [NC]
RewriteRule ^ /personel?%2 [R=302,L,NE]
This doesnt look right
RewriteRule ^-Contact-?&lang=en$ /-Nous-contacter-?lang=en [R=301,L]
I would think the & should only be used when you have more than one parameter being passed
e.g.
?lang=en&userId=13
I would try:
RewriteRule ^-Contact-?lang=en$ /-Nous-contacter-?lang=en [R=301,L]

.htaccess - catch multiple vars from query, write cookie, redir

.htaccess and regular expressions is twisting my mind :)
I'm trying to catch a variable number of variables from the query string, write them in a cookie and redirect removing query string. I got it working with only one variable but sometimes I need it to catch 2 or 3. Here's the code that works with one variable:
RewriteCond %{QUERY_STRING} ^(tag|aid|flu)=([a-z0-9]+)$ [NC] # look for interesting variables in url
RewriteRule ^(.*)$ $1? [CO=%1:%2:foo.com:14400:/,R=301,L] # capture url strip for vars, write cookie, redir
but clearly this is not going to work if the requested url is foo.com?tag=xx&aid=yyy&flu=bbb or with just two variables. I just can't seem to wrap my head around how to do this. Also it would be nice if the order of the variables didn't matter.
Thanks!
I don't know if it's possible to do that:
# tag
RewriteCond %{QUERY_STRING} (?:^|&)tag=([a-z0-9]+)(?:&|$) [NC]
RewriteRule ^ - [CO=tag:%1:foo.com:14400:/]
# aid
RewriteCond %{QUERY_STRING} (?:^|&)aid=([a-z0-9]+)(?:&|$) [NC]
RewriteRule ^ - [CO=aid:%1:foo.com:14400:/]
# flu
RewriteCond %{QUERY_STRING} (?:^|&)flu=([a-z0-9]+)(?:&|$) [NC]
RewriteRule ^ - [CO=flu:%1:foo.com:14400:/]
# Final
RewriteCond %{QUERY_STRING} (?:tag|aid|flu)=.+ [NC]
RewriteRule ^(.*)$ $1? [R=301,L]
