Passing parameters after creating ReWrite Rule - php

Question

Does anyone know how i can stop variables from being lost after creating a Rewrite Rule?
Putting in [QSA] gives me a Server 500 error message
I want this rule
RewriteRule ^family-name/([^/.]+)/([^/.]+)$ family-name.php?familyName=$1&token=$2 [L]
and this works in the sense of i get
family-name.php/somthing/token
However, when i go to $_GET['familyName'] or token it returns blank. why?
Note. the ReWrite rule is in my .htaccess page
UPDATE:
I have reduced my code down to this:
RewriteEngine On
RewriteRule ^my-family/family-name/([a-z]+)/([a-z0-9]+)$ my-family/family-
name.php?familyName=$1&token=$2 [QSA,L,NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+?)$ $1.php [NC,L]
My parameters are being passed through onto the next page LOCALLY ONLY and not when uploaded to my live site. Any thoughts???

Answer 1

You should open page (with your domain name).
http://example.com/family-name/something/token
And call your parameters with $_GET['token'], not $_SESSION['token'].
If you want RewriteRule for
http://example.com/family-name.php/something/token
You should have:
RewriteRule ^family-name.php/([^/.]+)/([^/.]+)$ family-name.php?familyName=$1&token=$2 [L]
