Code igniter routing for dynamic id

Question

How can I route to specific URL for URL having dynamic id. Suppose orginal URL is

 http:localhost/c2c/init/product/5     // here 5 is the id of the product.

In route.php

 $route["product/iphone-on-sale"] = "init/product/5";

But its not routing to http:localhost/c2c/product/iphone-on-sale when when original URL is entered.

Answer 1

You can try this

$route["product/iphone-on-sale/(:num)"] = "init/product/$1";

and your url will be

http://localhost/c2c/product/iphone-on-sale/5
