How to create clean url using .htaccess for multiple parameters? - apache

Question

I try to make clean URLS to my web site.
The desired format is: site/category/num example site/sport/3
Both category and page are optional parameters. So i have three rules. The problem is rule three. It only work in first time.
User enter site - tule 1. OK.
User navigate and pick category. Rule 2... OK.
User navigate and want page 2 page. (rule 3) OK.
User want see more items in page 3 (rule 3) Error..
I got parameter site/category/category/3 and navigatioin fail. Now i dont get why do i get category two times.

Answer 1

Try with:
RewriteEngine On
RewriteCond %{REQUEST_URI} (\.css|\.js|\.png|\.jpg|\.gif|robots\.txt)$ [NC,OR]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([0-9]+)/?$ /index.php?page=$1 [L]
RewriteRule ^([^/]+)/?$ /index.php?category=$1 [L]
RewriteRule ^([0-9a-zA-Z_-]+)/([0-9]+)/?$ /index.php?category=$1&page=$2 [NC,L]
