        */
       public function action_input(){
        echo Input::post('name');                                                                                                                                                 
        }

but i'm get error like this

http://docs.fuelphp.com/classes/input.html

<?php echo Input::post('foo') ?>

where "foo" is your POSTed parameter.

Either use a "View" (as suggested above in the comments) to display your response or do the following in your controller action.

return new Response(Input::post(<your_parameter_here>));

The primary reason is as quoted in the documentation.
http://docs.fuelphp.com/general/controllers/base.html

"A controller action MUST return a Response object. Optionally you can specify special HTTP headers, or a custom HTTP status code (a code other than "200 OK").

If your controller extends one of the base controllers, your action can also return any value that can be cast to string, like for example a View object. The after() method of the base controller will convert it into a Response object for you.

If your controller does not extend one of the base controllers, and you want to use this feature, your controller must contain it's own after() method that will accept the actions return value, and has to wrap it into a Reponse object which it must return. "
