i need to rewrite www.sample.com/user/john/ to www.sample.com/user/?u=john
this code works only if i leave out the trailing / "www.sample.com/user/john" how do i get it to work like "www.sample.com/user/john/" as well?
RewriteRule ^([A-Za-z0-9_]+)$ index.cfm?u=$1 [L]
now i would need it to function a step further
www.sample.com/user/john/23564/ to rewrite like "www.sample.com/user/?u=john&i=23564"
one thing "www.sample.com/user/john" should still word even w/o the/23564/
thanks
Add the optional slash (and the "user/" part of the URL):
RewriteRule ^user/([A-Za-z0-9_]+)/?$ index.cfm?u=$1 [L]
And the next step:
RewriteRule ^user/([A-Za-z0-9_]+)(/([0-9]+))?/?$ index.cfm?u=$1&i=$3 [L]

I'm new to the rewriting of urls and regex in general. I'm trying to rewrite a URL to make it a 'pretty url'
The original URL was
/localhost/house/category.php?cat=lounge&page=1
I want the new url to look like this:
/localhost/house/category?lounge&page=1
(like I say, I'm new so not trying to take it too far at the moment)
the closest I've managed to get it to is this:
RewriteRule ^category/(.*)$ ./category.php?cat=$1 [NC,L]
but that copies the whole URL and creates:
/localhost/house/category/house/category/lounge&page=1
I'm sure, there must be an easy way to say copy all after that expression, but I haven't managed to get there yet.
I will try to help you:
You probably have already, but try a mod rewrite generator and htaccess tester.
From this answer: The query (everything after the ?) is not part of the URL path and cannot be passed through or processed by RewriteRule directive without using [QSA].
I propose using RewriteCond and using %1 instead of $1 for query string matches as opposed to doing it all in RewriteRule.
For your solution, try:
RewriteCond %{QUERY_STRING} ^(.*)$
RewriteRule ^house/category$ house/category.php?cat=%1 [NC,L]
This will insert the .php and cat= while retaining the &page=
Anticipating your next step, the below mod rewrite may help get started in converting
http://localhost/house/category/lounge/1
to
http://localhost/house/category.php?cat=lounge&page=1
Only RewriteRule necessary here, no query string:
RewriteRule ^house/category/([^/]*)/([0-9]*)/?$ house/category.php?cat=$1&page=$2 [NC,L]
Use regex101 for more help and detailed description on what these regexes do.
If it still not working, continue to make the regex more lenient until it matches correctly:
Try to remove the ^ in RewriteRule so it becomes
RewriteRule category$ category.php?cat=%1 [NC,L]
Then it will match that page at any directory level. Then add back in house/ and add /? wherever an optional leading/trailing slash may cause a problem, etc.
Thanks for all your suggestions, I took it back to this
RewriteRule category/([^/])/([0-9])/?$ category.php?cat=$1&page=$2 [NC,L]
which has done the trick, and I'll leave it at this for now.
i have a problem with duplicate pages for SEO on a website i'm trying to fix. www.example.com/category/c1234 loads just the same as www.example.com/category/c1234garbage
I've been reading online and testing the code and so far I narrowed it down to a possible regex problem. I have the following lines
# url rewrites
RewriteCond %{REQUEST_URI} ^/index\.cfm/.+ [NC]
RewriteRule ^/index.cfm/(([^/]+)/?([^/]+)?)/?(.*)? /index.cfm/$4?$2=$3 [NS,NC,QSA,N,E=SESDONE:true]
I added an R in the rule so I could see if it was passing through there and it is and after it passes that the garbage at the end disappears.
Can someone help me understand this and figure out a way to fix it so when you go to www.example.com/category/c1234garbage it redirects to www.example.com/category/c1234
I've been searching online for quite a while now and thought it might be time to post here since I can't seem to find a solution. I'm reading "Mastering Regular Expressions" but it might take take a while for me to find the answers I'm looking for.
I appreciate any help you can give me. Thank you.
EDIT: This is what i have before that
RewriteEngine On
Rewritebase /
# remove trailing index.cfm
RewriteCond %{QUERY_STRING} ^$
RewriteRule ^index.cfm(\?)?$ / [R=301,L]
# remove trailing slash
RewriteCond %{QUERY_STRING} ^$
RewriteRule (.*)/$ /$1 [R=301,L]
# Remove trailing ?
RewriteCond %{THE_REQUEST} \?\ HTTP [NC]
RewriteRule ^/?(index\.cfm)? /? [R=301,L]
# SEF URLs
SetEnv SEF_REQUEST false
RewriteRule ^[a-z\d\-]+/[a-z]\d+/? /index.cfm/$0 [NC,PT,QSA,E=SEF_REQUEST:true]
RequestHeader add SEF-Request %{SEF_REQUEST}e
RewriteCond %{HTTP:SEF_REQUES} ^true$ [NC]
RewriteRule . - [L]
EDIT: I was reading the htaccess again and found this that I don't understand but it might have some connection. It's located at the bottom of the file.
# lowercase the hostname, and set the TLD name to an enviroment variable
RewriteCond ${lowercase:%{SERVER_NAME}|NONE} ^(.+)$
RewriteCond %1 ^[a-z0-9.-]*?[.]{0,1}([a-z0-9-]*?\.[a-z.]{2,6})$
RewriteRule .? - [E=TLDName:%1]
From your description and your code, it sounds like this is the transformation that's happening here:
www.example.com/category/c1234garbage
↓
www.example.com/index.cfm?category=c1234garbage
So the problem, I think, is not your rewriting rules. The problem is how you're handling querystring parameters on the server side. If you have an actual page called index.cfm that's interpreting those parameters, you should tweak the code behind that page to validate them and redirect to /category/c1234 where appropriate.
I think the code in index.cfm is looking at the parameter, checking to see if it starts with something recognizable, and going from there. You need to make it more strict.
Alternatively, you could add another .htaccess rule to parse the c1234garbage part and decide which part is valid, and which part (if any) is garbage. I can't give you a regex for that, though, since I don't know the rules for a valid input in your application.
Edit:
I think I found the problem. This part here:
RewriteRule ^[a-z\d\-]+/[a-z]\d+/? /index.cfm/$0 [NC,PT,QSA,E=SEF_REQUEST:true]
You specify the beginning of the relative URL with ^, but you don't specify that you want it to match all the way to the end. So I think what's happening is that it's taking the part of the string that matches, throwing out everything else, and appending it to /index.cfm/. So it takes only the /category/c1234 part from /category/c1234garbage, because that's the part that matches ^[a-z\d\-]+/[a-z]\d+/?.
You can probably fix this with just a word break:
RewriteRule ^[a-z\d\-]+/[a-z]\d+\b/? /index.cfm/$0 [NC,PT,QSA,E=SEF_REQUEST:true]
If that doesn't work, I'm afraid we've reached the end of my htaccess knowledge. I'm more of a regex guy.
Just BTW, this still seems a little awkward. If I understand this right, part of the URL will still get thrown out if it doeesn't fit your exact pattern. E.g. /category/c1234?abc=123 will lose its querystring parameters. You might want to redesign how your rules are set up.
I partially solved the problem. I added
# Remove garbage from after category
RewriteCond %{REQUEST_URI} [a-z\d\-]+/[a-z]\d+(.+)
RewriteRule ^([a-z\d\-]+/[a-z]\d+)/? $1 [R=301]
on top of the SEF rules. It's doing what i want which is to remove the garbage from the url but it gives me an infinite loop because its redirecting even when the url is clean. Any hints?
EDIT: So i realized that the .+ at the end is matching the numbers as well... How do i change it to match anything other than numbers after the numbers? basically where I have the .+ i need to have a "match any character except for numbers"
EDIT: I finally got it to work with the following code:
# Remove garbage from after category
RewriteCond %{REQUEST_URI} [a-z\d\-]+/[a-z]\d+[A-Za-z-.]+
RewriteRule ^([a-z\d\-]+/[a-z]\d+)/? $1 [R=301]
The (.+) i was using previously was reading the 2nd number (c1234)as being part of the . so it would always pass the the condition as true unless it was something like c1

RewriteEngine on
RewriteBase /
RewriteRule ^haveg/employer/([0-9]+)/(.*) haveg/employer.php?msg_id=$1
It works fine when i use
http://localhost/haveg/employer/7003/the-message-title
or
http://localhost/haveg/employer/7003/
The problem is here http://localhost/haveg/employer/7003 because i removed the forward slash at the end. it gives page not found error.
RewriteRule ^haveg/employer/([0-9]+)/?(.*) haveg/employer.php?msg_id=$1
I think adding a questionmark should allow it to match.
Try changing your last line to
RewriteRule ^haveg/employer/([0-9]+)([^0-9]*) haveg/employer.php?msg_id=$1
This should accept both cases.
I suggest you add another RewriteRule to make your intention clear. In this code the first rule handles the case when the URL ending with digits followed by an optional slash (when the msg_id query field is blank), and the second applies where there is a message following the digits.
RewriteRule ^haveg/employer/([0-9]+)/?$ haveg/employer.php?msg_id=
RewriteRule ^haveg/employer/([0-9]+)/([^/]+)$ haveg/employer.php?msg_id=$1 [L]
I need to match two cases
js/example_directory/example_name.js
and
js/example_directory/example_name.js?12345
(where 12345 is a digit string of unknown length and the directory can be limitless in depth or not exist at all)
I need to capture in both cases everything between js/ and .js
and if ? exists capture the digit string after ?
This is what I have so far
^js/(.*).js\??(\d+)?
This works except it also captures
js/example_directory/example_name.js12345
I want the regex to ignore that. Any suggestions?
Thank you all!
Test your patterns here
Answer:
Using Gumbo's information my final rewrite rule is as follows.
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{QUERY_STRING} ^\d*$
RewriteRule ^js/(.*)\.js$ js.php?f=$1.js&v=%0 [L]
</IfModule>
Include the whole querystring pattern, including the ? in one conditional match.
^js/(.*).js(\?\d+)?
mod_rewrite’s RewriteRule directive does only test the URI path and not the query. So using a rule like the following does already match both URIs:
RewriteRule ^js/(.*)\.js$ …
If you now want to test the query too, you need to use an additional RewriteCond:
RewriteCond %{QUERY_STRING} ^\d*$
RewriteRule ^js/(.*)\.js$ …
The match of the last successful RewriteCond can be referred to with %n, so in case of the whole match %0 or in this case even just %{QUERY_STRING} directly.
As far as regular expressions go - you can use the (?:) (non capture grouping) to make the \?(\d+) as a chunck, optional like so:
^js/(.*).js(?:\?(\d+))?
You really don't >need< to use the ?: (non capture) portion, but if you don't, back references will be changed - 1 will point at the filename, 2 will point at ?1234 and 3 will be 1234
Im just learning mod_rewrite and regex stuff, and what I'm trying to do is pass variables of any name, with any number of variables and values, into a script and have them forwarded to a different script.
here is what I have so far:
RewriteEngine on
RewriteRule ^script\$(.*[\])? anotherscript?ip=%{REMOTE_ADDR}&$1 [L]
That all seems to work except that one of the parameters I'm passing is a URL and the // after http:// always gets stripped down to one slash.
for example, I do
script$url=http://www.stackoverflow.com
then it redirects to:
anotherscript?ip=127.0.0.1&url=http:/www.stackoverflow.com
and the second script chokes on the single-slash.
I realize that preserving a double-slash is the exact opposite of what people usually do with mod_rewrite. Is there a way I can preserve the double-slash?
EDIT: Solution found with Gumbo's help.
RewriteCond %{THE_REQUEST} ^GET\ (.*)/script\$([^\s]+)
RewriteRule ^script\$(.*) anotherscript?ip=%{REMOTE_ADDR}&%2 [L]
I had to add that (.*) in front of /script on the RewriteCond, once I did that it got rid of the 404 errors and then it was just a matter of passing the matches through.
Try this rule:
RewriteCond %{THE_REQUEST} ^GET\ /script\$([^\s]+)
RewriteRule ^script\$.+ anotherscript?ip=%{REMOTE_ADDR}&%1 [L]
See Diggbar modrewrite- How do they pass URLs through modrewrite? for the explanation.
I Think there may be something wrong with the first part of your RewriteRule regex
^script\$(.*[\])?
The backslash ( \ ) is used to escape a special character into a litteral one, thus you are actually trying to match a closing bracket ( ] ), is that intended ?
try this
RewriteRule ^script\$(.*)? anotherscript?ip=%{REMOTE_ADDR}&$1 [L]
