Codeigniter Routing Unlimited Paramaters

Question

I currently have this in my CodeIgniter routes file. It maps anything with a URI api/controller/function to controller/api_function.

$route['api/(:any)/(:any)/(:any)/(:any)/(:any)/(:any)'] = '$1/api_$2/$3/$4/$5/$6';
$route['api/(:any)/(:any)/(:any)/(:any)/(:any)'] = '$1/api_$2/$3/$4/$5';
$route['api/(:any)/(:any)/(:any)/(:any)'] = '$1/api_$2/$3/$4';
$route['api/(:any)/(:any)/(:any)'] = '$1/api_$2/$3';
$route['api/(:any)/(:any)'] = '$1/api_$2';

As you can see, this isn't very efficient. I need a different routes line depending on the number of parameters supplied. Is there a way to automatically pass all parameters along? So hypothetically, I'm looking for something like...

$route['api/(:any)/(:any)/unlimited parameters'] = '$1/api_$2/unlimited parameters';

Thanks!

Answer 1

This Works perfectly,

$route['api/(.*)']='api/$1';

Answer 2

Try this:

$route['api/([^/]*)/([^/]*)/(.*)'] = '$1/api_$2/$3';

It basically checks for two segments (any character but a slash), then anything after that gets appended as parameters to your controller function.

This wouldn't match for routes with NO parameters, but it's not hard to do if that's a case you need to handle.

Answer 3

I believe just this would do:

$route['api/(:any)/(:any)'] = '$1/api_$2';
$route['api/(:any)/(:any)/(:any)'] = '$1/api_$2/$3';
