htaccess rewrite multiple folders - .htaccess

Question

hello here is my htaccess file :
RewriteEngine On
RewriteBase /
#REWRITE QUERY STRINGS!
RewriteCond %{REQUEST_URI} !^/(.*).php
RewriteCond %{REQUEST_URI} !^/(.*).html
RewriteCond %{REQUEST_URI} !^/(.*).js
RewriteCond %{REQUEST_URI} !^/(.*).css
RewriteCond %{REQUEST_URI} !^/(.*).png
RewriteCond %{REQUEST_URI} !^/(.*).bmp
RewriteCond %{REQUEST_URI} !^/(.*).jpg
RewriteCond %{REQUEST_URI} !^/(.*).gif
RewriteCond %{REQUEST_URI} !^/m
RewriteCond %{REQUEST_URI} !^/ar
RewriteCond %{REQUEST_URI} !^/fr
RewriteCond %{REQUEST_URI} !^/tr
RewriteCond %{REQUEST_URI} !^/en
RewriteRule ^(.*)$ /index.php?do=$1 [QSA]
now what this does is when I want to access : domain.com/home is like accessing domain.com/index.php?do=home which is great , but when I try to access french language for example : domain.com/fr/home it doesn't work but domain.com/fr/index.php?do=home works do you have any idea I can achieve this for tr language, arabic and english also.Thanks
PS: index.php file is located in fr , tr , ar and en folders

Answer 1

Try the folwoing code :
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !\.(php|html|js|css|png|bmp|jpg|gif)$
RewriteCond %{REQUEST_URI} !^/(m|ar|fr|tr|en)/
RewriteRule ^(.*)$ /index.php?do=$1 [QSA,L]
#three lines above summarize your original code and exclude all request
# for m,ar,fr,tr,en with / , it means when request to any directory
# of them
RewriteCond %{REQUEST_URI} ^/(m|ar|fr|tr|en)/(.*)$ [NC]
RewriteCond %{REQUEST_URI} !^/(m|ar|fr|tr|en)/index\.php [NC]
RewriteRule ^(.*)/(.*)$ $1/index.php?do=$2 [QSA,L]
# the three lines above will match any request passes the first rule
# and starts with any of your chosen directories and prevent any loop
If you want to exclude the same files extensions from the second rule you could add this line RewriteCond %{REQUEST_URI} !\.(php|html|js|css|png|bmp|jpg|gif)$ to it as well

You probably want to introduce a more general rewriting rule prior to your rule for the default language:
RewriteEngine On
RewriteBase /
RewriteRule ^/?([a-z]{2})/(.*)/?$ /index.php?lang=$1&do=$2 [END,QSA]
RewriteRule ^/?(.*)/?$ /index.php?do=$1 [END,QSA]
You may need to add some exceptions in form of RewriteConds or even switch to an explicit naming of possible language keys instead of the ([a-z]{2})...
If you experience an http status 500 ("internal server error") due to the END flag then chances are that you are using a very old version of the apache http server and need to use the L flag instead. Should work the same for this case.
And a general hint: you should always prefer to place such rules inside the http servers (virtual) host configuration instead of using dynamic configuration files (.htaccess style files). Those files are notoriously error prone, hard to debug and they really slow down the server. They are only supported as a last option for situations where you do not have control over the host configuration (read: really cheap hosting service providers) or if you have an application that relies on writing its own rewrite rules (which is an obvious security nightmare).
