htaccess remove index.php and add www to url in expressionengine - php

Question

i made a website by expressionengine, in the htaccess i need to remove the index.php and also add www to none www url's.
here is my current .htaccess:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
# Add www to url
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
# Directs all EE web requests through the site index file
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L,QSA]
# Removes index.php from ExpressionEngine URLs
RewriteCond %{THE_REQUEST} ^GET.*index\.php [NC]
RewriteCond %{REQUEST_URI} !/system/.* [NC]
RewriteRule (.*?)/index\.php/*(.*) /$1$2 [R=301,NE,L]
</IfModule>
but the above code has some problems, it works when the url has the www itself and there is no index.php anywhere and everything is fine, but when i remove the www from the url to test the "add www" part it does not work any more and the url damages lik this:
http://www.example.com/index.php?/segment1/segment2/
an index.php comes up. i don know what to do, any help will be appriciated

Answer 1

Try this..
RewriteEngine On
#Redirect non-www to www
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
it will remove index.php from the URL and add www as a prefix.

The www redirect probably doesn't work because there's no wildcard, keep it simple and specify your domain:
# Redirect to www
# -------------------
RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
I expect you have the removal and addition of index.php the wrong way around, I redirect it first if specified in the URL, then add it in hidden:
# Redirect specific index.php requests in URL
# ------------------------------
RewriteCond %{THE_REQUEST} ^GET.*index\.php [NC]
RewriteCond %{REQUEST_URI} !/system/.* [NC]
RewriteRule (.*?)index\.php/*(.*) /$1$2 [R=301,L]
# Directs all EE web requests through the site index file
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L,QSA]
Also try with and without the ? on this line, depending on the server setup, this might not be needed:
RewriteRule ^(.*)$ index.php?/$1 [L,QSA]
or
RewriteRule ^(.*)$ index.php/$1 [L,QSA]
