Redirect certain subfolders by removing the parameter question mark

Question

I am using .htaccess to redirect certain subfolders of my domain, to remove the question mark to improve my URLs.

Currently my URLs are like this:

Answer 1

i am using php GET parameters, i am attempting for when the browser visits example.com/post/sometitle that the page that is currently example.com/post/?sometitle is displayed

In that case you need to the opposite of what you are asking in your question: you need to internally rewrite (not externally "redirect") the request from example.com/post/sometitle to example.com/post/?sometitle.

However, you must have already changed all the URLs in your application to use the new URL format (without the query string). You shouldn't be using .htaccess alone for this.

I also assume that /post is a physical directory and that you are really serving index.php in that directory (mod_dir is issuing an internal subrequest to this file). So, instead of /post/?sometitle, it's really /post/index.php?sometitle?

For example:

RewriteEngine On

# Rewrite /post/sometitle to filesystem path
RewriteRule ^post/([\w-]+)$ /post/index.php?$1 [L]

So, now when you request /post/sometitle the request is internally rewritten and handled by /post/index.php?sometitle instead.

I have assumed that "sometitle" can consist of 1 or more of the characters a-z, A-Z, 0-9, _ and -. Hence the regex [\w-]+.

If this is a new site then you can stop there. However, if you are changing an existing URL structure that has already been indexed by search engines and linked to by external third parties then you'll need to redirect the old URLs to the new. (Just to reiterate, you must have already changed the URL in your application, otherwise users will experience repeated redirects as they navigate your site.)

To implement the redirect, you can add something like the following before the above rewrite:

# Redirect any "stray" requests to the old URL
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ([\w-]+)
RewriteRule ^post/$ /post/%1 [R=302,NE,QSD,L]

The check against the REDIRECT_STATUS environment variable is to ensure we only redirect "direct requests" and thus avoiding a redirect loop.

(Change to 301 only when tested as OK, to avoid caching issues.)

In Summary:

RewriteEngine On

# Redirect any "stray" requests to the old URL
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{QUERY_STRING} ([\w-]+)
RewriteRule ^post/$ /post/%1 [R=302,NE,QSD,L]

# Rewrite /post/sometitle to filesystem path
RewriteRule ^post/([\w-]+)$ /post/index.php?$1 [L]

UPDATE: If you have multiple URLs ("folders") that all follow the same pattern, such as /post/
