htaccess rewrite url with multiple parameters in a sub folder - php

Question

I need to rewrite the following url:
http://localhost/homemarket/products/C1/C2/
to
http://localhost/homemarket/products.php?catergory=C1&sub_category=C2
I tried searching all over stackoverflow, and found similar rewrite rules but I am facing the following problems:
These rules clash with my removing .php rules (adds .php to my sub_category query).
If subcategory is removed, its redirecting to 404 page.
If none of them are provided, its again redirecting to 404 page.
Here's what I have tried:
# Do not remove this line, otherwise mod_rewrite rules will stop working
Options +MultiViews
RewriteEngine On
RewriteBase /
#Prevent viewing of .htaccess file
<Files .htaccess>
order allow,deny
deny from all
</Files>
#Prevent directory listings
Options All -Indexes
#Error Documents
ErrorDocument 404 /homemarket/error.php?404
ErrorDocument 500 /homemarket/error.php?500
#Remove extensions
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^\.]+)$ /homemarket/buyers/$1.php [NC,L]
RewriteRule ^products/([^/]*)/([^/]*)/?$ /homemarket/buyers/products.php?category=$1&sub_category=$2 [NC,L]
DirectoryIndex index.php

Answer 1

Your first rule matches both uris, You need to exclude the slash in your rule so that it can not conflict with other rules :
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/.]+)$ /homemarket/buyers/$1.php [NC,L]
