URL Rewriting(.htaccess) index.php?page=foo&lang=en to /en/foo

Question

I am new to the URL Rewriting using .htaccess and I am strugguling with it.

What I want is to change the url similar to this http://www.example.org/index.php?page=contact&lang=en (lang has 3 options while the page value is changing depending on the current page) for example - to https://example.org/en/contact - non-www and https version).

Also if someone visits https://example.org/ I want to redirect them to https://example.org/en (default)

So far this is what I have in .htaccess and it doesn't work propertly.

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule ^\w+$ index.php?page=$0&lang=$1 [L]

RewriteCond %{THE_REQUEST} index\.php
RewriteCond %{QUERY_STRING} ^page=(\w+)(&lang=en)?$
RewriteRule ^index\.php$ /%1? [R=301,L]

Answer 1

Here is a .htaccess that matches your needs

RewriteEngine On

RewriteCond %{REQUEST_URI} ^(\/index\.php)?
RewriteRule (.*) https://%{HTTP_HOST}/en?

RewriteCond %{REQUEST_URI} ^(\/index\.php)?
RewriteCond %{QUERY_STRING} page=(\w+)&lang=(\w+)
RewriteRule (.*) https://%{HTTP_HOST}/%1/%2?

Explanation

The first condition and rule

RewriteCond %{REQUEST_URI} ^(\/index\.php)?
RewriteRule (.*) https://%{HTTP_HOST}/en?

will redirect the following urls to http://www.example.org/en

http://www.example.org
http://www.example.org/
http://www.example.org/index.php

The second conditions and rule

RewriteCond %{REQUEST_URI} ^(\/index\.php)?
RewriteCond %{QUERY_STRING} page=(\w+)&lang=(\w+)
RewriteRule (.*) https://%{HTTP_HOST}/%1/%2?

will redirect the following urls to http://www.example.org/contact/en `

http://www.example.org/index.php?page=contact&lang=en
http://www.example.org/?page=contact&lang=en
http://www.example.org?page=contact&lang=en

change contact and en with other values to see the changes

Answer 2

RewriteEngine On

#1
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [L,NE,R=301]

#2
RewriteRule ^/?$ https://%{HTTP_HOST}/en? [R=301,L]

#3
RewriteCond %{REQUEST_URI} index\.php
RewriteCond %{QUERY_STRING} ^page=(\w+)&lang=(\w+)$
RewriteRule "(.*)" "https://%{HTTP_HOST}/%2/%1?" [R=301,L]

Explanation

Block 1

Handles all Requests without https or with www.

http://www.example.org/whatever => https://example.org/whatever

Block 2

Handles root / requests and add en as default language

https://example.org/ => https://example.org/en

Block 3

Handles the index.php?page=x&lang=x Requests and replace Query Params with Path segments

https://example.org/index.php?page=contact&lang=en => https://example.org/en/contact

All 3 together should fulfill your described requirements

http://www.example.org/index.php?page=contact&lang=en => https://example.org/en/contact
