php - CodeIgniter Routing

Question

I am developing an ecommerce website with CI that has product categories and products. I want to route the URL so that it will go to the products controller, then run the getCategoryByName function for the first segment, then run the getProductByName for the second segment. Here is what I have:

URL:
products/docupen/rc805

routes.php:
$route['products/([a-z]+)'] = "products/getCategoryByName/$1";
$route['products/([a-z]+)/([a-z0-9]+)'] = "products/$1/getProductByName/$2";

But its not working. "docupen" is the category, and "rc805" is the product.

Thanks in advance.

Thank you all for your help. This is what I ended up with for what I needed.

$route['products/:any/:num'] = "products/getProductByID";
$route['products/:any/:any'] = "products/getProductByName";
$route['products/:any'] = "products/getCategoryByName";

My answer builds a bit on Colin's answer.

When I played around with the routes in CodeIgniter I came to the conclusion that the order of the routes was important. When it finds the first valid route it won't do the other routes in the list. If it doesn't find any valid routes then it will handle the default route.

My routes that I played around with for my particular project worked as follows:

$route['default_controller'] = "main";
$route['main/:any'] = "main";
$route['events/:any'] = "main/events";
$route['search/:any'] = "main/search";
$route['events'] = "main/events";
$route['search'] = "main/search";
$route[':any'] = "main";

If I entered "http://localhost/index.php/search/1234/4321" It would be routed to main/search and I can then use $this->uri->segment(2); to retrieve the 1234.

In your scenario I would try (order is very important):

$route['products/:any/:any'] = "products/getProductByName";
$route['products/:any'] = "products/getCategoryByName";

I don't know enough to route the way you wanted (products/$1/getProductByName/$2), but I'm not sure how you would create a controller to handle this particular form of URI. Using the $this->uri->segment(n); statements as mentioned by Colin in your controller, you should be able to do what you want.
