htaccess mod rewrite confusion - .htaccess

I am trying to apply mod rewrites to my URL to make it nicer but I am getting caught up in all the confusion of this subject.
Please could you help me out with the following examples of what I want to do :
I want to attach any variable from the root of my site into the lyprofile.php page
# Turn mod_rewrite on
RewriteEngine On
RewriteCond %{THE_REQUEST} /(.*)
RewriteRule /(.*) lyprofile.php?us=$1
I want a url such as profile/settings to go to lysettings.php
# Turn mod_rewrite on
RewriteEngine On
RewriteCond %{THE_REQUEST} /profile/settings
RewriteRule /profile/settings lysettings.php
These two examples if working should help me to work out all my other URL's, but I can't get these to work.
Also do you need an absolute URL, as I'm working on my local machine and an absolute URL would just cause a lot of hassle. Just in case my absolute URL is http://localhost/Linku2.5/

You generally want to go from the most specific rules to the least specific. Of the two things that you want to do, the first is the least specific, as (.*) can be anything. So we have to start with the much more specific and less arbitrary /profile/settings.
If these rules are in your htaccess file (in your case, in the Link2.5 directory), you don't want a leading slash, so simply:
# you only need to turn on once
RewriteEngine On
# Don't need absolute URLs, but you may need this line:
RewriteBase /Link2.5/
RewriteRule ^profile/settings lysettings.php [L]
Then, because your other rule is so general, you need to add some conditions so that you don't cause an infinite loop (the rewrite engine will continue to loop until the URI stops changing):
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^(.+)$ lyprofile.php?us=$1 [L,QSA]
If you know your "us" variable can only be numbers or letters, you can make the line with the rule a bit more specific:
RewriteRule ^([A-Za-z0-9]+)$ lyprofile.php?us=$1 [L,QSA]
etc.

Can you check this in vhosts config?
# Turn mod_rewrite on
RewriteEngine On
RewriteRule lyprofile\.php - [L]
RewriteCond %{REQUEST_URI} /(.*)
RewriteRule /(.*) lyprofile.php?us=$1 [L]
RewriteCond %{REQUEST_URI} /profile/settings
RewriteRule /profile/settings lysettings.php [L]

htaccess dynamic url redirect

I have the following URL
https://example.com/expert-profile?id=john-doe&locale=en
I want it to be redirected to
https://example.com/expert/john-doe
I tried the following
RewriteCond %{QUERY_STRING} ^(([^&]*&)*)id=([^&]+)&?(.*)?$
RewriteRule ^expert-profile$ https://example.com/expert/%3?%1%4 [L,R=301]
And a couple of other solutions, nothing is working here. Can someone help me to go in the right direction?
Update:
This is my current .htaccess file
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.html$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule . /index.html [L]
</IfModule>
Redirect 301 "/en/download-app" "/download-app"
Please keep your htaccess file in your root and have it in following way.
Please clear your browser cache before testing your URLs.
RewriteEngine ON
RewriteCond %{QUERY_STRING} ^id=([^&]*)&locale=(.*)$ [NC]
RewriteRule ^([^-]*)-.*/?$ $1/%1-%2 [R=301,L]
OR in case you don't have Rules to handle non-existing files/directories then use following Rules set. Please make sure either use above OR following Rules set one at a time only.
RewriteEngine ON
RewriteBase /
RewriteRule ^index\.html$ - [L]
RewriteCond %{QUERY_STRING} ^id=([^&]*)&locale=(.*)$ [NC]
RewriteRule ^([^-]*)-.*/?$ $1/%1-%2 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(?:expert)/([^-]*)-(.*)$ $1-profile?id=$1&locale=$2 [NC,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^ /index.html [L]
I have following URL
https://example.com/expert-profile?id=john-doe&locale=en
I want it to be redirected to
https://example.com/expert/john-doe
You would need to do something like the following at the top of your .htaccess file, before your existing directives (order is important):
RewriteCond %{QUERY_STRING} (?:^|&)id=([^&]+)
RewriteRule ^expert-profile$ /expert/%1 [QSD,R=301,L]
This captures the value of the id URL parameter (in the %1 backreference) regardless of where it appears in the query string and discards all other URL parameters. I'm assuming you don't specifically need to match locale=en?
Note that the regex subpattern ([^&]+) (the id value) only matches something, not nothing. If the URL parameter is empty (ie. id=&locale=en) then no redirect occurs.
The QSD flag is necessary to discard the original query string.
Test first with a 302 (temporary) redirect to avoid potential caching issues. And clear your browser cache before testing. Only use a 301 (permanent) redirect if this really is intended to be permanent.
To redirect the specific URL /expert-profile?id=<name>&locale=en to /expert/<name>, ie. the id parameter is at the start of the query string and is followed by locale=en only then you can (and should) be more specific in the condition. For example:
RewriteCond %{QUERY_STRING} ^id=([^&]+)&locale=en$
RewriteRule ^expert-profile$ /expert/%1 [QSD,R=301,L]
RewriteCond %{QUERY_STRING} ^(([^&]*&)*)id=([^&]+)&?(.*)?$
RewriteRule ^expert-profile$ https://example.com/expert/%3?%1%4 [L,R=301]
This is close (providing you placed the rule at the top of the file), however, this tries to preserve the other URL parameters, ie. locale=en and whatever else, to create another query string - which you've not stated in your requirements.
Aside: The existing answers are assuming you are wanting to internally rewrite (URL rewrite) the request in the other direction, ie. from /expert/john-doe to /expert-profile?id=john-doe&locale=en. This is probably due to how questions of this nature are notoriously miswritten and this is often the real underlying intention. However, you've made no mention of this here and a URL of the form /expert-profile is not a valid endpoint - so it wouldn't really make sense to "rewrite" the URL in that direction. (?)
If you want it rewritten, capture the name (.+) and insert it into the target $1
RewriteRule ^expert/(.+)$ /expert-profile?id=$1&locale=en [L]
And don't use flag R|redirect here, unless you really want a redirect.---
To redirect from expert-profile?id=john-doe to expert/john-doe, capture the id (.+?) from the query string and insert it in the substitution URL %1
RewriteCond &%{QUERY_STRING}& &id=(.+?)&
RewriteRule ^expert-profile$ /expert/%1 [R,L]
When everything works as it should, you may replace R with R=301 (permanent redirect).
Don't use both rules together. If you do, it will result in an endless redirect loop and finally give a "500 Internal Server Error".
Unrelated, but never test with R=301!

Htaccess - Rewrite engine (reverse engineering a line of code)

On a site I'm working on, if you enter the url, plus 1 directory, the htaccess adds a trailing slash.
So, this: http://www.mysite.com/shirts
Becomes this: http://www.mysite.com/shirts/
The htaccess that runs the site is quite long and complex, so it's not easy to find or test which rule is causing the rewrite. I was able to track down the issue to this line of code (I think):
RewriteRule (.*) http://www.mysite.com/$1 [R=301,L]
Does this rule match the behavior I'm describing above? It seems to be the cause, but it doesn't make logical sense to me. I don't unsderstand where the trailing slash is coming from.
Can someone shed some light on this for me? Thanks in advance.
Edit: MORE:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^mysite\.com$
RewriteRule (.*) http://www.mysite.com/$1 [R=301,L]
By default apache will add the ending /, you will have to use:
DirectorySlash Off
To disable that behavior which is caused by mod_dir, you can read more about it here.
However if you're trying to remove the / to fix images not showing. That is not the right way to do it, you should instead use the HTML base tag, for example:
<BASE href="http://www.yourdomain.com/">
Read more here about it.
Your current rule as you have updated on your question:
RewriteCond %{HTTP_HOST} ^mysite\.com$
RewriteRule (.*) http://www.mysite.com/$1 [R=301,L]
Means:
if domain on the URL is only mysite.com
redirect current URL to domain with www.
So an example of it would be, if you access:
http://domain.com/blog/some_blog_article
It will redirect the user to:
http://www.domain.com/blog/some_blog_article
Note how it retains everything and only add the www. to the domain.
If you really want to redirect it regardless here is one way to do it:
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^mysite\.com$ [NC]
RewriteRule (.*) http://www.mysite.com/$1 [R=301,L]
# check if it is a directory
RewriteCond %{REQUEST_FILENAME} -d
# check if the ending `/` is missing and redirect with slash
RewriteRule ^(.*[^/])$ /$1/ [R=301,L]
# if file or directory does not exist
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
# and we still want to append the `/` at the end
RewriteRule ^(.*[^/])$ /$1/ [R=301,L]

htaccess rewrite for subdomain only

I'm trying to rewrite some parameters to beautiful links, but for a subdomain / a folder only. Unfortunately I can't get it to work, maybe also because there are some other rewrites in line before...
Heres my code:
<IfModule mod_rewrite.c>
# NON-WWW TO WWW
RewriteEngine On
RewriteCond %{HTTP_HOST} ^example.com
RewriteRule (.*) http://www.example.com/$1 [R=301,L]
# WORDPRESS-BLOG
Options +FollowSymlinks
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
# REDIRECT FOR SUBDOMAIN
RewriteCond %{HTTP_HOST} ^subdomain.example.com
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/.]+)(?:/)?$ index.php?cshort=$1 [L]
RewriteRule ^([^/.]+)/([^/.]+)(?:/)?$ /index.php?cshort=$1&cid=$2 [L]
RewriteRule ^([^/.]+)/([^/.]+)/([^/.]+)(?:/.*)?$ /index.php?cshort=$1&cid=$2&step=$3 [L]
</IfModule>
Basically only the last part is the one I want to rewrite to change URLs from something like
http://subdomain.example.com/index.php?cshort=abc&cid=123&step=1 to http://subdomain.example.com/abc/123/1
The other rewriting rules for www.example.com shouldn't get affected. Unfortunately my current codes only does the first two rules for the blog and the www, but nothing happens on the subdomain. What's wrong in my code?
When you say that you want to rewrite from http://subdomain.example.com/index.php?cshort=abc&cid=123&step=1 to http://subdomain.example.com/abc/123/1 you mean that you want the user to enter the pretty URL and to have it serve the full URL in the background, not that you want to redirect from the ugly to the pretty URL, right?
In your RewriteRules, what are you trying to accomplish with "(?:/)?"? As written, that doesn't make any sense to me. If you're just trying to match whether or not the directory path ends with a slash, you can do that as follows:
RewriteRule ^([^/.]+)/?$ index.php?cshort=$1 [L]
EDIT: Additional suggestions:
Move the "Redirect for subdomain" section above the "Wordpress Blog" section. Since the Wordpress rule applies to "everything that's not a real file or directory, regardless of domain" that should go last.
RewriteConds only apply to a single RewriteRule that follows them. For each of the three rules you have listed under "Redirect for subdomain", after updating them per the above suggestion, you need to repeat the two RewriteCond lines in front of the RewriteRule.

RewriteRule For Matching Arbitrary PHP Files

I'm somewhat new to htaccess rewrite rules, and have been scratching my head for the past few days on what's happening here. No amount of Googling seemed to help, so hopefully somebody knows the answer.
I have a site that can be accessed as:
www.site.com
www.site.com/684
www.site.com/684/some-slug-name-here
All of these scenarios should go to index.php and pass in the optional id=684 and slug=some-slug-name-here
Which works fine.
My problem is I have a separate file. Right now it's called admintagger.php - but this fails when I call it anything. 21g12fjhg2349yf234f.php has the same issue.
The problem is that that I would like to be able to access admintagger.php from www.site.com/admintagger
but it seems to be matching my rule for index, and taking me there instead.
Here is my code:
Options +FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteRule ^imagetagger$ /imagetagger.php [NC,QSA]
RewriteRule ^([0-9]+)/?(.*)?/?$ index.php?id=$1&slug=$2 [NC,L,QSA]
If you want to arbitrarily be able to access php files via the name (sans extension) then you need to create a general rule for it. But you need to be careful otherwise you may be rewriting legitimate requests for existing resources (like a directory, or a slug). Try this instead:
# make sure we aren't clobbering legit requests:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# see if appending a ".php" to the end of the request will map to an existing file
RewriteCond %{REQUEST_FILENAME}.php -f
# internally rewrite to include the .php
RewriteRule ^(.*)$ /$1.php [L]
Then you can have your routing to index.php right after that:
RewriteRule ^([0-9]+)/?(.*)?/?$ index.php?id=$1&slug=$2 [NC,L,QSA]
Although you may be better off create a separate rule for each of your 3 cases:
RewriteRule ^([0-9]+)/([^/]+)/?$ /index.php?id=$1&slug=$2 [NC,L,QSA]
RewriteRule ^([0-9]+)/?$ /index.php?id=$1 [NC,L,QSA]
RewriteRule ^$ /index.php [L]

Trying to add trailing slash with htaccess, results in a absolute path

What I'm trying to achive is to have all urls on my page look like http://domain.com/page/, no extensions, but a trailing slash. If a user happends to write http://domain.com/page or http://domain.com/page.php it will redirect to the first url. After some googling i found this code, and it's close to working, but when you leave out the trailing slash in your request the url becomes something like http://domain.com/Users/"..."/page/ and therefor returns a 404.
My .htaccess looks like this:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{THE_REQUEST} ^GET\ /[^?\s]+\.php
RewriteRule (.*)\.php$ /$1/ [L,R=301]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*)/$ $1.php [L]
RewriteCond %{REQUEST_FILENAME} !(.*)/$
RewriteRule (.*)/$ $1.php [L]
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule .*[^/]$ $0/ [L,R=301]
I've been trying to add an additional rule but I really don't get any of this and I haven't been able to find any answers.
For a scenario like this one, the .htaccess author has to consider both what the browser URL bar should display and what file the web server should return/execute. Note also that each external redirect starts the processing of the rewrite directives over.
With that in mind, start by taking care of which file is returned when the URL is in the correct format:
RewriteEngine on
RewriteRule ^/?$ /index.php [L]
RewriteRule ([^./]+)/$ /$1.php [L]
Then, deal with URLs with no trailing slash by redirecting them with [R=301]:
RewriteRule ^/(.*)\.[^.]*$ http://www.example.com/$1/ [R=301,L]
RewriteRule ^/(.*)$ http://www.example.com/$1/ [R=301,L]
Note that the first of these two rules should also take care of the case where there is a filename (like something.php) but also a trailing slash by eliminating the filename extension and re-adding the slash.
Keep in mind that, if your internal directory structure does not match what the web server is serving (as is often the case in shared hosting scenarios), you will likely need to add a RewriteBase directive immediately after the RewriteEngine directive. See the Apache docs for an explanation.
