I'm sorry but I don't really completely understand how mod_rewrite works but I'd like to basically change the url:
/index.php?category=value1&video=value2
to be accessed via /value1/value2
could anybody tell me how to do this? thanks^^
Try this one here:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/?(.*)/(.*)$ index.php?category=$1&video=$2 [L]
The first line enabled the usage from the mod_rewrite.
The second line is a condition which checks if there is a file with that name. If not continue with the next line.
The third one is a regular expression. The ^ markes the beginning and the $ the end of it. The /? means that at the beginning should be a optional / (this depends on the server configuration). The (.*) meanes a range of chars which from 0 until n. The brackets meanes that there is a group which can be called as $n here as $1 and $2.
Please note that AllowOverride All must be enabled in the server configuration.

Okay, so I need to find the correct syntax for what I want to do.
These links:
http://www.example.com/sub1/sub2/product1/
(...)
http://www.example.com/sub1/sub2/product700/
need to redirect to
http://www.example.com/sub3/product1-newsite/
(...)
http://www.example.com/sub3/product700-newsite/
What I have tried:
RewriteEngine On
RewriteRule ^/sub1/(.*)/(.*)$ http://www.example.com/subdir/$1-newsite/ [R=301,L]
For all the 700 products.
Also I need to make exeptions for certain products.
Can someone see what I'm doing wrong?
I think it's just the numbering on the regular expression that is an issue.
$1 is the first matched group, $2 is the second, etc. $0 is for the entire string that matched (ie. the whole path).
Try:
RewriteEngine On
RewriteRule ^/sub1/sub2/(.*)$ http://www.example.com/subdir/$1-newsite/ [R=301,L]
or
RewriteEngine On
RewriteRule ^/sub1/(.*)/(.*)$ http://www.example.com/subdir/$2-newsite/ [R=301,L]
Edit
Ah... had a thought... the first regex in the capture may be being a bit too greedy... since it can match:
^/sub1/[sub2/product1-newsite]/[] so $1 will be sub2/product1-newsite and $2 will be empty (.* can happily match nothing).
So we need to make sure it doesn't grab too much.
RewriteEngine On
RewriteRule ^/sub1/([^/]+)/(.+)/$ http://www.example.com/subdir/$2-newsite/ [R=301,L]
Changing the * to + makes sure we match at least one character.
Changing the . to [^/] makes sure we match "anything except a /".
Added a / on the end to make sure the $2 doesn't capture the trailing slash.
That should hopefully fix it.
I've changed my CMS and need to write a mod_rewrite rule to help redirect some of the old URLs.
What I'd like to do is:
remove "blog/archives"
replace underscores with dashes
replace ".html" with a trailing slash
The old link:
http://example.com/blog/archives/the_post_title.html
The new link
http://example.com/the-post-title/
To address 1 & 3 I thought something along the lines of this might work, but it's not.
RewriteRule ^/blog/archives/([A-Za-z0-9-]+)/?.html$ $1 [L]
Thanks for your suggestions.
For 1 and 3
RewriteRule ^/blog/archives/(.*?).html$ /$1/ [L,R=permanent]
(note that R=permanent use a 301 redirect, which will be cached for long time but does move your pagerank to the new URL. Use [L,R] to use normal redirection)
I have managed to put this condition and rule below together to redirect a page to include index.shtml at the end of it but I dont understand what this part of the Rewrite means - the ^$ part. I believe ^ means start and $ is end but in this context I dont understand its meaning in "English" and how it works:
RewriteCond %{HTTP_HOST} ^www\.example1\.test\.com [NC]
RewriteRule ^$ http://www.example1.test.com/index.shtml [R,L]
Thanks.
^ is the start of the string, $ is the end. If there's nothing in between, as in the case of ^$, that means an empty string. Since the path leading up to the current directory is ignored, the part of the URL that matches is after the http://www.example1.test.com/. Matching an "empty string" after that means matching the URL itself, as in: with no file or anything else specified. So, this redirects the root URL to index.shtml
If a user visits the exact URL www.example1.test.com he or she is redirected to http://www.example1.test.com/index.shtml.

I'm german and i'm sorry about my damn sucking englisch.
RewriteRule ^admin/(.*)$ index.php?admin=$1
here is an example.
so the result i want is for example the id within, but as an optional parameter:
RewriteRule ^admin/(.*)/id-(.*)$ index.php?admin=$1&id=$2
Here the id don't must set thats what i want :)
The Link example (i want that here is the same result):
www.exmple.com/admin/edit-user
www.exmple.com/admin/edit-user/id-1
the problem is: the rule take anytime the first way with only this:
RewriteRule ^admin/(.*)$ index.php?admin=$1
can anybody help me ? :)
loving greetings m0.
Try changing the order of your rules and don't forget the [L] flag at the end :
RewriteRule ^admin/(.*)/id-(.*)$ index.php?admin=$1&id=$2 [L]
RewriteRule ^admin/(.*)$ index.php?admin=$1 [L]
Try an optional capture group:
RewriteRule ^admin/([^/]*)(/id-(.*))?$ index.php?admin=$1&id=$3
If there's no id specified, then $3 will be blank and you'll just get a blank id rewritten:
index.php?admin=edit_user&id=
If it is specified, then you'll get the id too:
index.php?admin=edit_user&id=1
The expression .* is too general as it matches an arbitrary length of arbitrary characters. A better expression would be [^/]+ that matches only one ore more arbitrary characters except / (path segments separator).
So try these rules:
RewriteRule ^admin/([^/]+)$ index.php?admin=$1
RewriteRule ^admin/([^/]+)/id-([^/]+)$ index.php?admin=$1&id=$2
For the second rule you could also replace the second [^/]+ with [1-9][0-9]* that would match only integers greater than 0.
RewriteRule ^admin/([^/]+)/id-([1-9][0-9]*)$ index.php?admin=$1&id=$2
try this:
RewriteRule /admin/([^/]*)/?(id-(.*))?$ index.php?admin=$1&id=$3
RewriteCond %{REQUEST_URI} !^/?new.php?url
RewriteRule ^/?(.+)\.?(.+)$ new.php?url=$0 [L]
its supposed to take any URL
mysite.com/someurl
and convert it to
new.php?url=someurl
however it keeps going to just new.php
You need to escape the second question mark in the first line so it matches a literal question mark:
RewriteCond %{REQUEST_URI} !^/?new.php\?url
Also you are not using the parenthesized groups on the second line. $0 is okay, or you may want $1 instead. If you use $0 you could simplify it a bunch:
RewriteRule ^.*$ new.php?url=$0 [L]
Or on the other hand if you're breaking apart the URL for a reason I would suggest some fixup. You're not matching the file name and extension exactly right. A little more complex regex like this would probably do you better:
RewriteRule ^/?(.*?)(?:\.([^.]*))?$ new.php?path=$1&extension=$2 [L]
Explanation:
(.*?) matches the directory and file name. The ? means match non-greedily, so stop as soon as the next part matches. The parentheses cause it to be captured and stored in $1.
(?:\.([^.]*))? matches the file extension. ?: turns says to not capture the outer set of parentheses, so the dot is not captured in $2. ([^.]*) matches the extension and ensures that it does not contain a dot. The final ? makes the file extension part optional, just cause not all URLs have file extensions. Thus there will only be a $2 if there is a file extension.
The first back-reference is $1 not $0 AFAIK. If that doesn't do it try specifying [QSA] as well, though I doubt that's it.
RewriteCond %{REQUEST_URI} !^/?new.php?url
RewriteRule ^/?(.+)\.?(.+)$ new.php?url=$1 [L]
The first back reference should be $1 instead of $0.
RewriteCond %{REQUEST_URI} !^/?new.php?url
RewriteRule ^/?(.+)\.?(.+)$ new.php?url=$1 [L]
It also depends on what other lines of code you have in the file. It's also possible to mess up rewrites if you have another code that conflicts with it.
