htacces url rewriting with rewrite condition - php

Question

Currently, i have system which works through htaccess like need to hardcore url everytime a new product is added to the system, something like below
RewriteRule ^18th-and-19th-century$ sub_category.php?id=18th-and-19th-century
RewriteRule ^20th-century-furniture$ product.php?id=20th-century-furniture
RewriteRule ^pair-lacquer-cabints$ product_info.php?id=pair-lacquer-cabints
and also there are few static pages as,
RewriteRule aboutus aboutus.php?
RewriteRule contactus contactus.php?
the Idea here, what i want is to redirect the product info, category info to some index.php and access the static page as they are,
RewriteRule aboutus$ aboutus.php?
RewriteRule contactus contactus.php?
RewriteRule ^ index.php?
i tried this but everytime it takes me too the index.php page,i think there needs to some condition thing here but not able to understand how to go forward
Thanks in Advance

Answer 1

Try
RewriteEngine On
RewriteRule ^sub_category/([^/]*)$ /sub_category.php?id=$1 [L]
RewriteRule ^product/([^/]*)$ /product.php?id=$1 [L]
RewriteRule ^product_info/([^/]*)$ /product_info.php?id=$1 [L]
Output URLs will be
http://example.com/sub_category/18th-and-19th-century
http://example.com/product/20th-century-furniture
http://example.com/product_info/pair-lacquer-cabints

Answer 2

You have wrote the all url at same directory level, so there is no way you can write dynamic .htaccess rule. You need to add some identifier or some pattern in all different kind of url's which are going to access different php page.
RewriteRule ^18th-and-19th-century$ sub_category.php?id=18th-and-19th-century
RewriteRule ^20th-century-furniture$ product.php?id=20th-century-furniture
RewriteRule ^pair-lacquer-cabints$ product_info.php?id=pair-lacquer-cabints
RewriteRule aboutus aboutus.php
Like in above pages you can use url's in following style
Subcategory URL: www.domain.com/18th-and-19th-century
Product URL: www.domain.com/18th-and-19th-century/list or www.domain.com/18th-and-19th-century/20th-century-furniture
Product info: www.domain.com/18th-and-19th-century/20th-century-furniture/pair-lacquer-cabints
OR
Subcategory URL: www.domain.com/category/18th-and-19th-century
Product URL: www.domain.com/product/20th-century-furniture
Product info: www.domain.com/product_info/pair-lacquer-cabints
So accordingly you can define levels and write rewrite rules.
Similarly you can write URL for static pages
www.domain.com/content/aboutus
www.domain.com/content/contactus
or
www.domain.com/aboutus [if you don't use first level URL for subcategory like www.domain.com/18th-and-19th-century then you can use for static pages]
if this answer is helpful to you then i will write .htaccess rules
