How to render the data from form to controller actions?

This is my controller:-

class ViewController < ApplicationController   def index   end

  def new     @txt=params[:txt]   end

end

Index Page:-

<form method='post'action='view/new' >   <input type="text" name="txt">   <input type="submit"> </form>

New Page:-

<h1>View#new</h1> <p>Find me in app/views/view/new.html.erb</p> <h2>Hello <%= @txt %></h2> <%= link_to 'index','index' %>

Error after filling text box and cliking the submit button:-

ActionController::InvalidAuthenticityToken in ViewController#new ActionController::InvalidAuthenticityToken RAILS_ROOT: D:/projectNetBean/validation

It looks like you are not passing the authenticity token

Are you using form_for in the view?
