mod_rewrite: avoid similar URLs go to the same page.php

I'm trying to work with mod_rewrite without particular problems but this:

RewriteRule ^(product/)([^/\<\>].+?)(/)([^/\<\>].+?)(/edit)/?$             php/prd_edit.php
RewriteRule ^(product/)([^/\<\>].+?)(/)([^/\<\>].+?)(/components/edit)/?$  php/prd_comp_edit.php

the first URL is for this kind of contents when I'd like to edit the main infos:

http://site.com/product/Nintento/Wii/edit => php/prd_edit.php

the second URL is when I'd like to edit the list of compone开发者_Python百科nts inside the products

http://site.com/product/Nintento/Wii/components/edit => php/prd_comp_edit.php

If I digit the second URL, mod_rewrite redirect the requesto to prd_edit.php instead of prd_comp_edit.php, because it read Wii/components as a product name.

I thougt to avoid this by use ([^/\<\>].+?) to specify the product can't have chars like / but it still read the product name as Wii/components.

How can I fix this?

First, move the second rewrite first and add [L] flags to them, this will fix your problem and here are some more optimisations.

RewriteRule ^product/(.+?)/(.+?)/components/edit/?$ php/prd_comp_edit.php?cat1=$1&cat2=$2 [L]
RewriteRule ^product/(.+?)/(.+?)/edit/?$ php/prd_edit.php?cat1=$1&cat2=$2 [L]

Now, given your example, $_GET['cat1'] == "Nintendo" and $_GET['cat2'] == "wii"

RewriteCond %{REQUEST_URI} ^/product
RewriteRule /components/edit/?$ php/prd_comp_edit.php [L]
RewriteRule /edit/?$ php/prd_edit.php [L]

This way you will be able to have deeper nested product groups as well :D

EDIT

$uri = $_SERVER['REQUEST_URI'];

// Split the URI apart using explode or any other suitable method
$parts = explode('/', rtrim($uri, '/'));

// Now throw away any part that is not connected to a product
// You know that the URI started with product and also know
// that it ended with components and/or edit

// $x = file is prd_comp_edit.php ? 3 : 2
$parts = array_slice($parts, 1, count($parts) - $x);

// Now there you have it, the products hierarchy ready to be processed further
