Question

I have a simple page with one textfield and a submit button. I want a user to be able to enter a string, and have the submit button direct the user to a certain page, where the textfield is in the URL as the :id.

For example, if the user enters “test”, clicking submit should send him to “/controller/action/test”.

Is this possible? I tried:

<%= form_tag :controller => "myController", :action => "myAction", :id => :textFieldName do %> ...

but that does not work. (I didn’t suspect it would.)

Thanks

You’d have to use Javascript. In the simplest form

$('form').submit(function() {
  $(this).attr('action') = '/url/prefix/' + $(this).find('input#the_field').val();
  return true;
});

And then the handler should return and the form should submit to the new url.

Note that you should also validate/normalize the field’s content.
