I have following URL:
myUrl?path=123¶m=val
Can you help me to write regular expression which will return path value. i.e
123
at this case?
P.S.
I have
REQUEST_URI and QUERY_STRING arguments.
P.S.
more global goal:
rewrite following url:
site.com/cat1/cat2?path=val¶m=ololo
to
site.com/cat1/cat2/val
P.P.S
I have read following answer:
https://stackoverflow.com/a/2252242/2674303
but there are a bit another situation.
RewriteCond %{QUERY_STRING} (.*(?:^|&))path=([^&]*)(.*)
RewriteRule ^/?cat1/cat2$ /cat1/cat2/%2? [PT]
Note, the final '?' drops the old query string.

I am learning .htaccess
My URL string is
http://abc.bcd.com/company/abc
I do apply to redirect my page if the company name is abc, xyz etc. and my rewrite rule is
RewriteRule ^/company/(.*?)$ /hhhhh/ll/test_page.html?company_letter=$1 [L,PT]
Sometimes my url change to
http://abc.bcd.com/company/abc?locale=en
What will be query string condition to accommodate both the url and should work properly ?
I have tried this but not helping .
RewriteCond %{QUERY_STRING} ^locale=(.*)$
The rewrite condition should help me like
if(locale="something")
/hhhhh/ll/test_page.html?company_letter=abc&locale=something
else
/hhhhh/ll/test_page.html?company_letter=abc
You just need to add QSA flag in your rule:
RewriteRule ^/?company/(.*)$ /hhhhh/ll/test_page.html?company_letter=$1 [L,QSA]
QSA (Query String Append) flag preserves existing query parameters while adding a new one.
The query string part of the incoming URL is a very specific thing. First you should know that classical rewriteRules are not managing the query string.
So, for example, you cannot make a RewriteRule with a check for a query string parameter value. Query strings parameters could be repeted several times, could appear in any order, and are not url-decoded (the location part of the url is url-decoded when mod_rewrite works on it).
This explains why some RewriteCond are sometimes used on the %{QUERY_STRING}, it cannot be done in RewriteRule but could be tested in rewriteCond, with all the previous probelsm ( repetition, order, url-encoding, etc).
But some rewriteRule tags can be applied for query string managment. Currently your tags are [L,PT], which also be writtent [last,passthrough].
You can add a qsappend or QSA tag which explicitly tells mod_rewrite to combine the original query string and the generated one.
So with
RewriteRule ^/company/(.*?)$ /hhhhh/ll/test_page.html?company_letter=$1 [last,passthrough,qsappend]
This:
http://abc.bcd.com/company/abc
Will go to
/hhhhh/ll/test_page.html?company_letter=abc
And this:
http://abc.bcd.com/company/abc?locale=en
Will go to
/hhhhh/ll/test_page.html?company_letter=abc&locale=en
Like so many I am struggling with what ought to be a simple rewrite
The initial form is something like:
http://cassie-family.co.uk/individual.php?pid=I807&ged=Cassy%20Family%20History.ged
The last parameter only needs rewriting, as in:
http://cassie-family.co.uk/individual.php?pid=I807&ged=Cassie%20-%20Cassy%20Family%20History
I have tried to trap the first parameter using:
RewriteCond %{QUERY_STRING} ^pid=([^&]+) [NC]
The nearest (incorrect) RewriteRule is:
RewriteRule ^(.*)$ individual.php&pid=%1&ged=Cassie%20-%20Cassy%20Family%20History [L, NC, R=301]
The moment I try to replace the '&' after individual.php with the correct '?' the URL is written as:
http://cassie-family.co.uk/individual.php
So.. the parameter is being trapped correctly but the rewrite rule is clearly mangled. The error lies in here:
^(.*)$ individual.php&
What construct should I be using to replace only the 2nd (passed-in) parameter value (which is always the same fixed string) with a different 2nd value (which is always the same but slightly different fixed string)? Adding a B flag seems to make no difference.
All suggestions welcome,
Thanks,
Ric
I don't understand why I always have such a massive problem with rewrite rules, but I simply want to append to the query string if it exists and add a ? if it does not. I actually don't care if the URL is changed in the browser or not -- it just has to load the correct target page.
RewriteRule /cia16(.*)\?(.*) /cia$1?$2&CIA=16
RewriteRule /cia16(.*) /cia/$1?CIA=16
If I go to /cia16/steps.php?page=1 it actually gets rewritten to /cia/steps.php?CIA=16 -- that is it seems accept the query string part is not even considered part of the URL for the purposes of the rewrite.
What do I have to do to get the rewrite to work properly with an existing query string?
You can't match against the query string within a RewriteRule, you need to match against the %{QUERY_STRING} variable in a RewriteCond. However, if you want to just append the query string, you can just use the QSA flag:
RewriteRule /cia16(.*) /cia/$1?CIA=16 [QSA]
The URI: /cia16/steps.php?page=1 would get rewritten to /cia/steps.php?CIA=16&page=1. If for some reason, you need the page=1 before the CIA=16, then you can do something like this:
RewriteRule /cia16(.*) /cia/$1?%{QUERY_STRING}&CIA=16
I have a website with joomla and I need to redirect (301) some links
They are in this form (index.php?Itemid= identify them - all links that doesn't have this part shouldn't be redirected)
/index.php?Itemid=544&catid=331:savona&id=82356:smembramento-dei-cantieri-baglietto-di-varazze-lopposizione-delle-maestranze&option=com_content&view=article
This should work
RewriteRule ^index.php?Itemid(.*)$ http://www.ligurianotizie.it/archive/index.php?Itemid$1 [L,R=301]
But the first ? (question mark) seems to cause problems.
In fact, if we suppose that the links are without the question mark
/index.phpItemid=544&catid=331:savona&id=82356:smembramento-dei-cantieri-baglietto-di-varazze-lopposizione-delle-maestranze&option=com_content&view=article
I would use
RewriteRule ^index.phpItemid(.*)$ http://www.ligurianotizie.it/archive/index.php?Itemid$1 [L,R=301]
and everything is perfect. But unfortunately real links has that question mark, and I have to find a solution.
What I have to do with that question mark?
Is the ? character escaped? try to add the NE (noescape) flag like this:
RewriteRule ^index.php?Itemid(.*)$ http://www.ligurianotizie.it/archive/index.php?Itemid$1 [L,R=301,NE]
The part behind the question mark is the query string. You can use RewriteCondto determine if it is not empty, and based on that make the decision to redirect.
Note: Query String
The Pattern will not be matched against the query string. Instead, you must use a RewriteCond with the %{QUERY_STRING} variable. You can, however, create URLs in the substitution string, containing a query string part. Simply use a question mark inside the substitution string, to indicate that the following text should be re-injected into the query string. When you want to erase an existing query string, end the substitution string with just a question mark. To combine a new query string with an old one, use the [QSA] flag.
Source: http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html
This should help you:
RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} Itemid
RewriteRule ^index.php(.*)$ http://www.ligurianotizie.it/archive/index.php$1 [L,R=301]
Every link containing "Itemid" will be redirected, the others not.
Even simple .htaccess gives me headaches and I need to do the following generic mapping:
http://example.com/project/controllername/key1/val1/key2/val2/.../keyN/valN
-->
http://example.com/project/controllername.xyz?key1=val1&key2=val2...&keyN=valN
example:
http://example.com/so/pagecontroller/id/1/time/12345/title/helloworld
-->
http://example.com/so/pagecontroller.xyz?id=1&time=12345&title=helloworld
Any guidance will help! Especially with handling special chars like '/', '?' and '&' (more?) in keys and values.
EDIT: To clarify, 'project' and 'controllername' paths are dynamic - they are not static. Also the number of keys and values is not pre-determined! I need help in creating the htaccess file code and where to place this file in the web tree and if apache needs restarting everytime the htaccess file is modified. Thanks!
Try these rules:
RewriteRule ^([^/]+/[^/]+)/([^/]+)/([^/]+)(/.+)?$ $1$4?$2=$3 [QSA,N]
RewriteCond $1 !.+\.xyz$
RewriteRule ^([^/]+/[^/]+)$ $1.xyz [L]
As long as you don't want to select those special characters, they should be no problem. A rule for your example might be:
RewriteRule http://example.com/so/pagecontroller/id/([0-9]+)/time/([0-9]+)/title/(.*)$ http://example.com/so/pagecontroller.xyz?id=$1&time=$2&title=$3
I don't think you can have a dynamic number of variables in a rewrite rule. But what you can do is the following:
RewriteRule http://example.com/so/pagecontroler/(.*) http://example.com/so/pagecontroler.xyz?vars=$1
Than you have a GET parameter with the name "vars" and the rest of the query as a value. You can than split the different keys and values server side e.g. with the explode() function of PHP.
