.htaccess rewrite multiple urls - php

Question

I need help with this rewrite in .htaccess file.
So this what I have now ans this works but when I try to add a new RewriteRule nothing happens.
I the url that I want to be rewrite is index.php?page=$1
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ profile.php?username=$1
So when I do it like:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ profile.php?username=$1
RewriteRule ^(.*)$ index.php?page=$1
The page doesn't have any css when i do it like:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ profile.php?username=$1
RewriteRule ^(.*_)$ index.php?page=$1
The page has css but i still get index.php?page=pagetitle. But the profile page does give me /username.

Answer 1

RewriteRule ^(.*)$ profile.php?username=$1
RewriteRule ^(.*)$ index.php?page=$1
Your are asking the server to redirect every URL to two different pages, it cannot work the server cannot just guess what page to load.
What you need is either a /profile/username rule or a /page/pagetitle rule.
IE something like:
RewriteRule ^profile/(.*)$ profile.php?username=$1 [QSA]
RewriteRule ^(.*)$ index.php?page=$1 [L]

Your rewrite rules are based on regular expressions and therefore need to be as specific as possible so the server can determine exactly which url to use - for example how can you tell if http://example.com/something is a page or a profile? Using a prefix such as "user", "profile", etc on your URLs means that http://example.com/profile/something can be redirected as as a username with a default redirect for everything else. To accomplish this you need to make the more specific pattern match first (users) and utilized the [L] directive to indicate that following rules should not be processed. I usually use a negative character class for URLs to match anything except a forward slash - [^/]*.
# Enable mod_rewrite
RewriteEngine On
# Set the base directory
RewriteBase /
# Don't process if this is an actual file or directory
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Does this url start with /profile and then followed with additional characters?
RewriteRule ^profile/([^/]*)$ profile.php?username=$1 [NC,L]
# Assume everything else is a page
RewriteRule ^(.*)$ index.php?page=$1 [NC,L]
Test at http://htaccess.madewithlove.be/ (note that %{REQUEST_FILENAME} and %{REQUEST_FILENAME} aren't supported for testing).
Profile
input url
http://www.example.com/profile/something
output url
http://www.example.com/profile.php
debugging info
1 RewriteRule ^profile/([^/]*)$ profile.php?username=$1 [NC,QSA,L]
This rule was met, the new url is http://www.example.com/profile.php
The tests are stopped because the L in your RewriteRule options
