return array( '_root_' => 'welcome/index', // The default route '_404_' => '404', // The main 404 route 'generalnumber2/:idea/:batchcode' => 'Generalnumber/series?batchcode=$2', ); but it is not working i am geting 404 i.e page is not found error can some one tell me the correct code for this.
Fuel doesn't support GET variables in routes. That would work if it would do a secondairy HTTP request with the route result, but it doesn't, route results are resolved internally.
Also, you have to be careful with using capitals in your routes, by default Fuel is case sensitive, so that might be the cause of the 404 too.
