In Grails you submit the data to a controller. The request will be processed by the action specified in the form's action attribute. Like:

<form method="POST" action="login">

You can get the values of the inputs from this page inside the controller action via params, which is a map with the id of the attribute as a key and its value as, well, value. Like:

def fname = params.fname

And finally, you can render another view passing these params you just received. Like:

render(view:'page', model:[parameters:params])

There are many ways you can use render though. Maybe you can find a better one for your use.
