Question

I found a Question similar to my problem(Regular Expression For URL Query) but could not make my problem to be resolved.

So I am having trouble with Regular Expressions in HTACCESS.

So what I have in my website is :

ROOT : (my web root is in a sub folder ‘sites’)

/sites/index.php and other files

/sites/sites/sample_folder_name/

Now what I would like to do is to ReWrite URL :

/sites/sites/sample_folder_name/file_name.php

to :

/sites/file_name.php?siteredirect=sample_folder_name

Remember :
If the URL contains any Request Parameters, then those must also be rewrited, i.e :

Example :

/sites/sites/sample_folder_name/file_name.php?cat_id=1&user=2

to :

/sites/file_name.php?cat_id=1&user=2&siteredirect=sample_folder_name

The parameters are supposed to be unknown instead of user and cat_id. It could be any parameters. Means that whatever is written after .php should also come in URL.

Means :

/sites/sites/sample_folder_name/file_name.php?if_any_parameters

then :

/sites/file_name.php?if_any_parameters&siteredirect=sample_folder_name

otherwise :

/sites/file_name.php?siteredirect=sample_folder_name

Currently, the rewrite is working great but I am not able to make them work with parameters.

What I have in my HTACCESS right now :

RewriteRule ^sites\/([0-9A-Za-z_]+)\/([0-9A-Za-z_]+)\.php(.*)$ $2.php(?(?=$3)$3&)siteredirect=$1 [L]
RewriteRule ^sites\/([0-9A-Za-z_]+)\/$ index.php?siteredirect=$1 [L]

After this, it is giving me a 404.

Please Help… Where am I doing it wrong !

You need the QSA flag (Query String Append):

RewriteRule ^sites(/sites/[^/]+)/([^/]+)$ $1?siteredirect=$2 [QSA]

What’s more, invert your rules: you won’t have to use L

Also, consider using <Location> directives, it will make your job easier:

<Location "/site/site">
    #rules here
</Location>

<LocationMatch "^/site/(?!site/)">
    #rules here
</Location>
