php request vars in sef urls

I have a page (ie www.mysite.com/products.php?catid=5) in which I use the $_REQUEST[catid'] to get the category id and use it in a query. I switched to SEF urls and now the urls display like www.mysite.com/products/category/5

How can I use the new urls to retrieve the catid value?

The following lines were used in the .htaccess file for switching to SEF urls:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/index.php
RewriteCond %{REQUEST_URI} (/|\.php|\.html|\.htm|\.feed|\.pdf|\.raw|/[^.]*)$  [NC]
RewriteRule (.*) index.php
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
Solution

  • You need to rewrite the URL correspondingly using mod_rewrite for example.

    RewriteRule ^(.*)$ index.php?url=$1 [NC,QSA]

    This rule would rewrite the URL www.mysite.com/products/category/5 to www.mysite.com/index.php?url=products/category/5. From this point on you can parse the variable $_GET["url"] or refine the rewrite rule.
