I consider myself reasonably competent with PHP. I am, however, completely and totally lost when it comes to mod_rewrite.
I have a URL structure that works like the following:
http://site/something/something-else/the-actual-page/
that redirects to:
http://site/index.php?page=the-actual-page
It's only ever the final 'folder' that is passed to the script. The preceding 'folders' (if any) are for SEO and structure purposes.
If there is a preceding folder "promotion" then it redirects to a separate file. This is along the lines of:
http://site/promotion/campaign-name/
redirecting to
http://site/promotion.php?campaign=campaign-name
I'm using the following code to achieve this:
<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine On
RewriteRule ^promotion/(.*)/$ promotion.php?params=$1 [L]
RewriteRule ^(.*) index.php?page=$1 [L]
</IfModule>
This works as intended, with links redirecting properly EXCEPT when there is no trailing slash. For example
http://site/something/thepage/
will work, whilst
http://site/something/thepage
will not.
To solve this problem I'm attempting to set up a 301 that redirects any URI without a trailing slash to a URI with a trailing slash.
The code below (placed above the other rules) works to a degree, but I lose folder data.
Code:
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1/ [L,R=301]
The problem?
http://site/something/thepage
redirects to
http://site/thepage/
I'm afraid all the googling in the world is not helping me, as I cannot wrap my brain around mod_rewrite at all!
Appreciate any help.
You'll be better off using this:
RewriteEngine On
RewriteCond %{REQUEST_URI} /+[^\.]+$
RewriteRule ^(.+[^/])$ %{REQUEST_URI}/ [R=301,L]
# ... your other rerites
If you'd like to reverse it and strip the trailing slash instead, then use this:
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [R=301,L]
You'd then need to change your rewrite accordingly:
RewriteRule ^promotion/(.*)$ /promotion.php?params=$1 [L]

I've just started trying to figure out how to make clean URLs with .htaccess but it seems I've run into a wall straight away... I've got the following simple .htaccess:
RewriteEngine on
RewriteRule ^([a-zA-Z0-9-]+)$ index.php?id=$1 [L]
RewriteRule ^([a-zA-Z0-9-]+)/$ index.php?id=$1 [L]
It mostly works as expected: mysite.com/somepage goes to mysite.com/index.asp?id=somepage etc.
Except when the id is 'images'. When I try mysite.com/images it displays: mysite.com/images/?id=images (though the page still loads fine)
By the way mysite.com/images/ (with a slash) works ok. I've been searching for a solution for the last few days and that's the best I could get.
Since images is a directory Apache's mod_dir module adds a trailing slash after your rewrite rules. You can turn this feature off and add a trailing slash yourself:
DirectorySlash Off
RewriteEngine on
# add a trailing slash
RewriteCond %{DOCUMENT_ROOT}/$1 -d
RewriteRule ^(.*?[^/])$ %{REQUEST_URI}/ [L,R=302]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([a-zA-Z0-9-]+)/?$ index.php?id=$1 [L,QSA]
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/$1 [R=301,L]
# check if it is a directory
RewriteCond %{REQUEST_FILENAME} -d
# check if the ending `/` is missing and redirect with slash
RewriteRule ^(.*[^/])$ /$1/ [R=301,L]
# if file or directory does not exist
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
# and we still want to append the `/` at the end
RewriteRule ^(.*[^/])$ /$1/ [R=301,L]
I'm kind of new to the whole .htaccess thing and I've been trying to modify it so that none of my links will have trailing slashes at the end of their respective URLs. My website is filmblurb.org.
The code for the .htaccess where Wordpress begins and ends looks like this:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
I would appreciate it if someone can lead me in the right direction on how to fix this. Thanks.
You can add a RewriteRule to eliminate the trailing slash:
RewriteRule ^(.*)/$ $1 [R=301,L]
The issue is not caused by .htaccess, but rather by a combination of wordpress permalinks and .htaccess.
Login to your site and navigate to the permalinks, then if you aren't using the custom structure option, switch to it and make sure to not have a trailing slash at the end:
/%category%/%postname%
Then add this to your .htaccess file, above the
RedirectMatch 301 ^(.*)/$ /$1
That is better than using rewrite since it's a redirect and not a rewrite.
If that still doesn't work then I recommend you install the yoast seo plugin and there is a setting in it to do this.
This works for me; removing all trailing slashes from all routes while emphasizing that REQUEST_URI starts with a slash (at least in .htaccess files):
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} /(.*)/$
RewriteRule ^ /%1 [R=301,L]
Just don't use %{REQUEST_URI} (.*)/$. Because in the root directory REQUEST_URI equals /, the leading slash, and it would be misinterpreted as a trailing slash.

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=$1 [L]
EDIT: Additional suggestions:
Move the "Redirect for subdomain" section above the "Wordpress Blog" section. Since the Wordpress rule applies to "everything that's not a real file or directory, regardless of domain" that should go last.
RewriteConds only apply to a single RewriteRule that follows them. For each of the three rules you have listed under "Redirect for subdomain", after updating them per the above suggestion, you need to repeat the two RewriteCond lines in front of the RewriteRule.
What I'm trying to achive is to have all urls on my page look like http://domain.com/page/, no extensions, but a trailing slash. If a user happends to write http://domain.com/page or http://domain.com/page.php it will redirect to the first url. After some googling i found this code, and it's close to working, but when you leave out the trailing slash in your request the url becomes something like http://domain.com/Users/"..."/page/ and therefor returns a 404.
My .htaccess looks like this:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{THE_REQUEST} ^GET\ /[^?\s]+\.php
RewriteRule (.*)\.php$ /$1/ [L,R=301]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule (.*)/$ $1.php [L]
RewriteCond %{REQUEST_FILENAME} !(.*)/$
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.
