textbox to session

Can anyone help me out with storing a user's location to session to be used several times by a user during a login ? I need to create a textbox where the user enters there zip code and then I need to hold that zip code value in session to be used for several queries throughout the user's time within the site. I also would like to return the user's actual town and state after the zip is submitted but that is of lesser importance. I think I almost have the controller code but not quite there yet

def store_location   session [:location] = params[:location] end

I think its close although I am new and not totally sure what it is doing. The view code I don't even know how to start though and I assume it is only the controller and the 'store location' view that I need to code for?

Thanks

The code you have there will do what you expect -- it will store exactly what is on the form submitted to that controller into the session.

thank you what does the view look like though - I am weakest on the view side right now, horrible at html,css...

I'll paste a simple controller and an associated view (which includes a form). That might help.

Here is my login form, in app/views/session/new.rhtml

<div class="contentbody"> <% form_tag(:controller => "session", :action => "create") do -%> <div><label for="login">Login</label><br/> <%= text_field_tag 'login' %></div>

<div><label for="password">Password</label><br/> <%= password_field_tag 'password' %></div>

<div><%= submit_tag 'Log in' %></div> <% end -%> </div><!-- contentbody -->

And here is the part of my controller which handles it:

class SessionController < ApplicationController   def new   end

  def create     if using_open_id?       open_id_authentication(params[:openid_url])     else       password_authentication(params[:login], params[:password])     end   end

  def destroy     # self.current_user.forget_me if logged_in?     cookies.delete :auth_token     reset_session     flash[:notice] = "You have been logged out."     redirect_back_or_default '/'   end

  def password_authentication(login, password)     self.current_user = User.authenticate(login, password)     if logged_in?       successful_login     else       failed_login     end   end

  def failed_login(message = "Authentication failed.")     flash.now[:error] = message     render :action => 'new'   end

  def successful_login     redirect_back_or_default('/')     flash[:notice] = "Logged in successfully."   end end

OK I think I have the view working, textbox is there here is my method in the controller:

def store_location     session[:location] = params[:location]     redirect_to :action => 'list'     flash[:notice] = "your location is " end

so right now you enter a zipcode and it should be storing it to the session, the redirect keeps me on the same page and the flash notice seems to work as well. What I would like to do now is add to that flash notice the actual value I just stored in the hash...something like ...flash[:notice] = "your location is " + [session value]

can anyone help with the syntax on this?

BTW does that session code look correct for actualy getting the zip stored in the session? I have not been able to verify yet becasue I cant get the flash to return it.

here is my view code just in case you need it...

<%= start_form_tag :action => 'store_location'%> <%= text_field 'location', nil %>   <%= submit_tag 'your location' %></form> <%= end_form_tag %>

look ok?

"Your location is #{params[:location]}" would work.

Note that it is subject to XSS attacks if it is displayed to 3rd parties. You'd need to escape the HTML in it if it was.
